Let's do what we say, we have collected more than 3000, add a more chapter, character explosion, long live the motherland!

sent away the guests from all over the place, and checked the various gifts obtained for his daughter's full moon, which couldn't help but scare Shouhan.

The officials at all levels in his own system are not counted, because the Shouhan has words first, and the one who gives gifts more than Yu Lu will go to Bao Zhongchen to drink. Therefore, most of these people's gifts can be summed up by courtesy and affection. Of course, a guy like Zhang Xiaohu can be an exception, and he can say that it was my previous savings.

The large gifts were sent by various surrounding forces. These guys, as soon as they make a move, are gems and pearls that are calculated in liters and buckets. This really made Li Shouhan feel ashamed, and lamented loudly that he was a dirt bun.

However, if you have nothing to do, you will naturally be a traitor or a thief.

Oh, it's not a good word to use here, and naturally it's a courtesy that people must ask for something.

The purpose of these people is as if they had been discussed.

"Buy arms!"

"Buy knives and guns!"

"Buy cannons!"

"Buy armor!"

"Buy cotton!"

"Buy porcelain!"

"Buy silk!"

"Buy something from Nanzhong, and the general allowed us to buy it!"

As a result, the shopkeepers of the Han Yuan firm happily checked the stacks of contract documents stacked high in front of them, and looked at the gold piled up as high as a mountain in the treasury.

That's right! In view of the huge regional disparity between gold and silver, Shouhan only accepted gold in foreign trade, mainly export trade. Of course, if you accept silver, you have to consider the difference in exchange rates.

"The statistics are out." Lin Huofeng, the big shopkeeper of the Han Yuan firm, held the account book in his slightly reserved hand and replied in front of Shouhan.

"The dyed cotton cloth ordered from all over the place amounted to 141,300 horses. Among them, 35,600 horses were paid in full, 27,000 horses were used for raw materials, mainly cotton, and the rest were paid 30% of the deposit according to the rules. ”

"The number and variety of those who buy porcelain, silk, raw silk, etc., are rather chaotic, and I will report them later. The largest amount and quantity of goods are the military orders that the lord said. I paid all at once, and the amount was ......," Lin Huofeng lowered his voice and burst out a terrifying number to everyone present.

A few years back, this number may have caused many people to have a sudden cerebral hemorrhage, but now, people's psychological capacity is much stronger. Rao is so, and some people have stopped smacking their tongues.

Zhang Xiaohu's third brother Zhang Xiaoqi is one of them.

"These guys, what do you want so many knives, spears, guns, and cannons?"

"Shopkeeper Zhang, you don't know about this. According to adults, it's called an arms race. What would you do if your neighbor had a good knife or a spear in your hand and you only had a woodcutter in your hand? ”

"Birds! Lao Tzu must have two knives, or a knife and a gun, to sleep! ”

"That's a good point, but if you have a knife and a gun, what about the people who have an enmity with you? Isn't it time for a firebolt? ”

"That's right! That's how it should be! ”

"Hehe, the third shopkeeper, your idea is exactly what this generation thinks, and in the end, we received a contract for more than 200 artillery pieces! There are more than 5,000 sets of armor, 30,000 knives, and 50,000 funeral guns! There are also some people who are negotiating with us and want to buy some firecrackers from Ha Jing to go back, but the lord is still hesitating here. If you count the firecrackers, then you have to add 10,000 more. ”

"We are demanded, or rather begged, to be handed over to them within three months, even if they are informed, and their ships will come and carry them away."

"Lao Lin," Shouhan, who was sitting on the tiger-skin chair behind the handsome case, was speechless for a long time, "These artillery, to the order of more than 200 guns?" What kind of cannons are they? Don't sell your weapons to others, in the future, these cannons will fall on us! ”

"My lord, I have eighty small Franc machines, fifty-five large Franc machines, forty three-pounder guns, and forty-seven six-pounder guns, for a total of two hundred and twenty-two."

"Made! The numbers are quite auspicious, in pairs! Shouhan cursed, picked up a list on the table, and looked at it.

According to the technical level and cost of artillery manufacturing in this era, Shouhan made a very conscientious offer for his artillery to be sold to the outside world, taking the Franc machine as an example, a large Franc machine with a gun body weight of about 200 catties, excluding the weight of the gun and the gun carriage, the external price is 3,200 taels of silver. Five guns and twenty cannons were given. And send gunsmiths for after-sales service, including teaching and packing.

Later, this method of pricing was found to be a loss, for no other reason, because ductile iron was much stronger in ductility, toughness, and tensile resistance than traditional bronze and iron cannons, and its own weight was much lower.

The list included the Dutch, the Japanese, the Zheng and Mo families in the north, the Taungoo and Arakan kings of Burma in the west, and the Siamese who had signed treaties with Nanzhong and claimed to be vassals.

It includes almost all the political and military forces in the surrounding area, and as for those small toasts, they ask for the purchase of some swords, guns, armor and the like, and if there is a fire gun for sale, then it is thanks to the Bodhisattva.

"Since we have received money from others, we have to give them things." After thinking about it for a while, Shouhan made such a decision.

"Tomorrow, come with me to the workshop."

"This powerful regime, in its embryonic years, until recently, has been technologically creating illusions and deceiving the whole world. As far as the most common metal manufacturing process, or military equipment manufacturing technology, is concerned, for a long time, we have thought that it was done by relying on huge manpower, as many people have pointed out in their own writings, the so-called crowd tactics. However, after carefully studying the population and food consumption in the area under Lee's rule at that time, I was surprised to come to the conclusion that it was impossible for Li Shouhan to devote the huge manpower we imagined to the activities of casting artillery and smelting metal. ”

Vladimir. Ilyich. Ulyanov peeled off Li Shouhan's mask in his monumental work "The Eastern Empire - Technology".

Shouhan took the black goggles handed over by Ling Zheng on the side, and carefully watched as the molten iron was carefully poured into the mold. Nowadays, goggles have become a popular thing among the generals at all levels of the Navy Division and the Land Division. At first, it was Zhang Xiaohu's tired guy, who found that this thing had an excellent effect on preventing the dazzling sunlight, so he begged for half from Shouhan, and half begged for twenty pairs of half-grinding and half-laid, and distributed them to the ships under his command as paramilitary equipment for the captain and the spear and sail captain. Seeing that the left wing of the water division was there, Zuo Tianpeng on the right wing was not to be outdone, and begged for twenty pairs. Immediately afterwards, there was Gonzalez, who was practicing the fleet in the martial arts hall, and the Guards Battalion, Xuanwu Battalion, Phoenix Battalion, and Qilin Battalion reached out to ask for it.

In desperation, the defenders had to be evenly wet with rain and dew, one for each battalion officer, one for each artillery officer, and one for each rangefinder. As the same equipment as clairvoyance, I register and make a book.

Today, the main firearms of the South China Army are composed of rockets, 12-pounder guns, eight-pounder guns, big franc machines, small franc machines, and firearms, which are simple, cheap, and effective.

The material used is the most deceptive nine-turn steel - ductile iron. Interested friends can check that the excellent casting performance, heat resistance, corrosion resistance, wear resistance, vibration damping, machinability, economy, ductility and toughness of ductile iron are far more than the best material for making guns in this era, bronze.

"Lord, now we have made some adjustments to the original artillery-making process!" In the gun station, people came and went, the sound of metal crashing, and the neighing of mules and horses transporting all kinds of materials made Ling Zheng have to shout loudly to the guards.

In order to meet the requirements for artillery in various places, the technicians of the gun station reformed the cylinder forging method that was originally suitable for bronze cannons to the iron mold water cooling method. That is, the iron mold casting process proposed by Gong Zhenlin is combined with the Rodman method, and improved according to the characteristics of its own material, ductile iron. After a small-scale trial, the Artisan Guild approved the process.

Today is the day when the cannon casting officially begins.

After 1,200 to 1,300 degrees of high temperature training by the blast furnace, the ductile iron became liquid, and the liquid ductile iron was dumped into the hollow iron mold with a water injection pipe, and with the injection of molten liquid, the workers on the side began to slowly add water to the water injection pipe in the iron mold. The water flow slowly enters the cooling pipe in the iron mold from the water inlet set at the tail of the gun, and flows slowly in the mold along the line designed by people, cooling the enthusiasm of the melt with its own calm, and soon, the cold water becomes lukewarm, and the warm water becomes boiling water, and the boiling water flows out of the outlet at the tail of the gun with hot gas, completing its own task.

"The climate in Nanzhong is hot, it is obviously impossible to cast a cannon with a clay mold that is popular in the mainland, and the mold forging method proposed by the lord is certainly superior, but the technical requirements for processing tools and staff operation are very high. It is inconsistent with the requirements of large-scale production, short production cycle and low cost put forward by the owner. Ling Zheng defended those guys who were "bold" and "arbitrary" to change the process process formulated by the lord.

However, Shouhan's attention was not on these words, he just hummed a little casually, and his eyes were fixed on the young men in the workshop wearing yellow shoulders.

"Those people graduated from the academy according to the vocational education proposed by the lord, and after receiving education in various schools, they went to the workshop for internships. We have discussed that there will be a team of 50 people, and each team will only learn one link of craftsmanship, and they will not mess around with each other. As the head of the workshop, Ling Zheng followed Shouhan's gaze and immediately introduced the origin of this group of people to Shouhan.

"The weight of the country cannot be shown lightly. The smelting of these nine turns of steel and the manufacture of artillery are the foundation on which our South Central Army depends for survival in this troubled era, and we must not lose it! ”

The ten molds were quickly filled with the melt, and the water injectors in charge of cooling began to speed up their movements.

"My lord, this method of mold casting seems to be extensive, and farm tools and weapons can be made by this method. Save labor and time, one worker will earn hundreds of profits, and one cannon will save dozens of times the capital. And spin casting spin out, no delay days, flawless, natural smooth, twice the result with half the effort, infinite use. ”

Listening to Ling Zheng's slightly self-boasting words, Shouhan couldn't help but have some mixed feelings in his heart: he thought that it was most appropriate to use bronze to forge a cannon, but he didn't want to become a casting cannon because of the advent of ductile iron, or the iron mold water-cooled casting method that was respected by countless people. Is it really as everyone says, one step ahead is a genius, and two steps ahead is a madman?

Through the goggles, people clearly saw that the originally red cannon barrel began to dim. "Keep cooling!" A foreman shouted loudly, and more than a dozen workers responsible for filling the barrel mold responded in unison: "Fill water!" ”

Dozens of native laborers carried two large wooden barrels to supply water to and from the water injectors.

"Lord, it's going to take some time to cool down, we might as well go and see something else?" Feng Mofeng, who was in charge of the arsenal and the gun station, asked in a low voice in Shouhan's ear.

"What to see?"

"The springs you mentioned, the sons and daughters have made them."

The spring production site was not as heavily guarded as the gun station, and in an open space at the Taipingdong Arsenal, people were busy with their tasks.

Thick coarse porcelain rods are placed in the open space, and people use large pliers to pick up the red nine-turn steel bars that are burned at furnace temperature and carefully wound them on the coarse porcelain sticks.

The usually tough and strong nine-turn steel, under the action of high temperature, hum! It is also a hundred refined steel turned into finger wrapping soft. Under the action of workers and pliers, they are obediently wound around the coarse porcelain rod one by one, and the distance between each is equal. After cooling, the formed and fixed nine-turn steel bar is removed from the porcelain rod, and whether it is a qualified spring is determined according to the manufacturing level of the steel bar.

Depending on the size of the mold during processing, from a huge rod to a thumb-sized porcelain bar, large and small springs are placed in front of people's eyes.

To be honest, people can guess the general direction and purpose of other things that have been guided by Shouhan in recent years, but what exactly can be used for this thing called a spring is not known to people after a long time of arguing with each other.

"What is it for?" Shouhan flicked the springs of different sizes with satisfaction, "You'll know in a moment." ”

"Huang Leiting!" Shouhan greeted the representative of the artillery division loudly.

"Mark it in!"

"You go and ask Mr. Feng if the gun carriage that your artillery division asked him to process is ready."

"If you go back to the lord, the gun carriage has been prepared, and there are two sets of various artillery pieces, all of which are stored in the warehouse." Feng Mofeng, who was accustomed to silence, answered Shouhan's words in the crowd.

Soon, at the firing range of the test guns, the twelve-pounder guns and the six-pounder guns were placed in two groups, and the randomly selected gunners stood nervously and excitedly according to their respective positions.

Not far behind them, there was a group of people led by Li Shouhan.

"The artillery is all the same gun, the difference is in the gun carriage. On one group of gun carriages, the group under the Yellow Banner is equipped with your newly made springs, and the other group is not equipped with springs, the same gun position, the gunner's technical level is also about the same, and you will know after a while that this spring is useful! ”

Artillery rumbled.

Shells were pushed out of the chamber by gunpowder and flew towards the mound in the distance.

Today, the gunners can show off their artillery skills in front of the lord, and all of them are full of 120,000 spirits, and they will operate many links such as clearing, charging, loading, aiming, and firing like their peers.

However, the moment the cannon was discharged, the craftsmen noticed some subtle differences:

The two thick springs installed behind the side of the gun barrel and closely connected to the gun carriage were compressed tightly by the barrel moving backwards, but they also absorbed a lot of castration of the gun barrel, and as the gun carriage moved backwards, the springs bounced away and pushed the gun barrel forward. Several gunners took advantage of the situation to push the gun forward, quickly reset, clear the chamber, load the cartridge, load, aim, and fire. After that, reset again. And so on and so forth.

On the other side, there was no spring mounted artillery team, although the gunners were also confident in their operation, but after a few rounds of shells were discharged, the gunners' body consumption was huge, and the time interval between resetting the guns became longer and slower. Finally, a gunner fell like a puddle of mud next to the gun carriage.

So that's it!

The craftsmen somewhat understood.

The two springs, as well as the connecting rod installed together with the spring, constitute the most primitive reentry machine, the spring is the reentry spring, and the connecting rod plays the role of the reentry rod. Although the process is crude, the principle is the same.

When the gun recoils, the reentry rod attached to the gun at the tail end is pulled back. At this point, the reentry head compresses the reentry spring. At the end of the recoil, the reentry spring is extended, and the reentry rod is pushed forward, and the reentry rod drives the gun body back to its original firing position. There are many different types of reentry machines, some use reentry springs, some use compressed gas, and some use both. However, regardless of the type of reentry machine, it works by compressing the spring using recoil energy. Compress the gas or compress the spring and gas, and then use the stored energy to return the gun body to the original firing position.

"My lord! That's a good thing! "Huang Lei was very excited as if he was drunk, and his face was flushed." In the past, every time the sons and daughters fired more than a dozen guns, they were so tired that they couldn't do it, and they just marked it down, and the Yellow Flag artillery team fired thirteen guns, and the gunners were still full of energy, and the artillery reset speed was very fast. ”

"Lord Huang, you don't know anything!" Ling Zheng next to him didn't know when he was standing next to Shouhan with a flintlock pistol. He was about to hand the fire gun in his hand to Shouhan to watch.

"There's a lot of use for this thing!"

Ling Zheng pointed to the position of the dragon head and explained to Shouhan in a low voice, and Huang Lei hurriedly leaned over to watch. Although the flintlock pistol is easier to operate than the arquebus, the musketeers do not need to check the arquebus, and do not need to carry a bundle of rope with them, but the dumb fire rate of this thing is really higher, and the good character is about twenty percent, and the bad character is almost thirty percent!

That's not all, every time you pull the trigger, you can't wait to concentrate all the strength of your body on your index finger, otherwise, you won't be able to make a spark!

"We make the spring zuò small and tight, installed in the position of the faucet, only need to gently pull the trigger, under the action of the spring hammer can hit the flint fiercely, both increase the probability of firing and reduce the force of the trigger, the dolls have calculated, every ten times the trigger, the average firing rate is around eight!"

"Eight times?" Hearing this, Huang Lei couldn't help but smack his tongue secretly, which means that the blind fire rate is around 10%?

"But when you calculate it, the consumption of flint is much higher! Alas! Everything has a benefit and a disadvantage, and sugarcane is not sweet at both ends! Ling Zheng smacked his lips, expressing regret.

"It's okay!" Shouhan waved his hand very generously, well, this feels good, and it has a bit of a leader's taste. "What is a flint worth? How many more enemies can you kill and how many fewer casualties can you kill when you come? The merit is immeasurable! ”

Hearing this, I heard the hearts of the people around me slander: Others accumulate merits, they are burning incense and kowtowing, eating fasting and reciting Buddha, buying birds, fish and shrimp to release them, you can do it, killing people is accumulating merit?

"The enemy has killed a lot, and our army has few casualties, isn't this considered a merit?"

Well?

The lord's words also sound quite reasonable, and besides, the lord is the person chosen by the emperor, he said yes, that's right!

"Also, there are other folk uses for this spring, let's not talk about it today, I'll have someone send the drawings over when I go back, and you can beat a few pieces of furniture to me."

Shouhan has already made up his mind to set up sofas and chairs in the two rooms of the sisters Yanmei'er, Xiuxiu, and Meishan, and it is best to replace the bed with a spring! In addition, it seems that springs can also be installed in the car as a shock absorber, so that hey, hey, hey!

There are always people who come to interrupt Shouhan when he is in an infinite reverie for his own selfish desires.

There is one right now.

"Lord, lord?" Ling Zheng's son, Ling Li, rushed over from the gun station.

Ten molds have cooled, and several craftsmen are using calipers to test the caliber of the guns.

"The caliber is the same!" The muzzle of the cannon was tested with the same eight-pounder shell, and the distance between the shell and the muzzle was almost the same, and several craftsmen signed their names and fingerprinted on the inventory. From the beginning of the casting of these guns, the craftsmen and technicians of each link will sign the relevant inventory and leave fingerprints and bucket baskets, and once there is a quality problem in use in the future, the military room will track it down step by step, until it is the person who releases it. After that, there is the terrible phase of accountability.

"Gun No. 1. The caliber model is a twelve-pounder gun, the material is nine-turn steel, and the manufacturing process is cast. The clearance between the shell and the muzzle is one-twenty-fifth of the inner diameter, which is within the permissible range! ”

A technician carefully measured the inner diameter of a gun, carefully measured the gap between the shell and the inner diameter of the muzzle with the caliper in his hand, and nodded with satisfaction. The general casting artillery process of this era, the clearance between the inner diameter of the muzzle and the shell, is basically about one-tenth, and the south reaches one-twenty-fifth, in terms of accuracy alone. Already surpassed almost all the countries of this era that had the technology of artillery manufacturing.

However, there are more stringent links to come.

After detecting the caliber, it is necessary to enter the next link, and use a boring machine to boring the inner wall of the gun chamber to ensure the smooth range of the inner wall of the gun.

Outside the gunner's factory, an aqueduct was built to divert water from the river in the distance to several huge cisterns. These cisterns are not used to ensure the livelihood of people, but to serve other purposes.

In addition to ensuring the production water of the factory, they are also used to provide power for the factory.

A few brass whistles sounded, and two flags waved.

The workers on duty at the reservoir slowly turn the winch to lift the gate of the reservoir, and the water stored in the reservoir rushes forward along a narrow passage.

A waterwheel is placed at the mouth of the channel, and the blades of the waterwheel are just below the outlet channel, and the turbulent water quickly pushes the blades up, and the waterwheel rotates slowly. A long pole connected to the waterwheel rotated slowly but firmly as the waterwheel turned.

The long rod provides the original and reliable power for a horizontal boring machine installed indoors.

On the boring machine, iron steel (that is, steel made of high manganese ore sent by the Mo family, calcined soft manganese ore, removed the impurities in the ore, and obtained manganese dioxide ore containing about 70% of manganese, after many crucible steelmaking tests, the process formula containing 10%-13% of manganese was obtained, and a more satisfactory high manganese steel was obtained, and the first batch of products of high manganese steel with extremely high hardness became tool steel without exception, and were made into all kinds of knives and cutting tools. After mass production, the process is determined to first calcine the soft manganese ore to remove the impurities in the ore to obtain relatively pure manganese dioxide. Then the manganese dioxide and iron ore are mixed together for coke steelmaking, and the oxygen in the iron ore and manganese dioxide will be reduced under the enthusiastic combustion of coke, and then the crystallization of love - high manganese steel will come out. In order to continue the consistent pit style of Shouhan, high manganese steel is no exception to be given a deceptive trade name, iron steel. It is said to have come from an ancient beast. It resembles a buffalo, but has huge horns, black fur, and feeds on iron. Excrement is as good as steel and can be used as weapons. The blade began to spin at a constant speed, heading straight for the barrel of the cannon that was fixed to the wooden frame on the opposite side.

After a tooth-aching sound of metal cutting, someone made a gesture to indicate that the processing of the gun chamber had been completed. The workers guarding the waterwheel hurriedly pulled the ram to stop the waterwheel slowly, and at the same time signaled to the workers on the sluice gate to drop the sluice plate on the canal and stop the power brought by the water flow to the waterwheel.

Several apprentices pulled the chains on the pulleys, and after a loud sound, the cannon was hoisted high, and some metal debris floated out of the muzzle, ignition, etc. Some people use thin brooms and brushes to clean and oil the inside of the gun chamber.

Soon, another group of technicians in charge of the inspection arrived with their own equipment.

The two men took out a steel plate cut into a circle, slightly smaller than the caliber of the gun, from the tool kit, and passed a thin metal rod through the round hole in the center of the steel plate, and the two small claws at one end of the metal rod made a soft sound with the steel plate, "click".

A slightly fatter technician lifted the simple detection tool and stretched straight into the barrel along the muzzle, the feeling of contact between the steel plate and the inner wall was slightly astringent, but the steel plate reached the bottom of the barrel.

Another technician placed a burning incense stick down at the place of the ignition, "Can you see that?" He asked his colleague.

The fat technician opened his eyes and looked into the barrel of the gun, and in the observation holes reserved on both sides of the steel plate, no burning incense was found, "I can't see it!" ”

This detection method uses the principle of straight line propagation of light, if the person at the muzzle of the gun can see the bright spot of the incense, it means that the position of the ignition port and the gun chamber is deviated, either the position of the ignition port is wrong, or the opening is too large.

The steel plate that served as a simulated medicine pack was removed, and the technician removed another heavyweight inspection tool.

A twelve-pound cannonball, unlike a regular cannonball, had a depression in the shell, a thin beam above the depression, and a thin rope made of raw silk slowly extended as the cannonball entered the chamber.

"A position artillery, cast in March in the spring of the sixth year of the Apocalypse, boring machine processing on the 17th, tested by technicians Kuang Xiaoshan and Li Mingxi, the muzzle of the cannon is positive, the chamber of the cannon is straight, the position of the ignition port is appropriate, the shell is smooth into the chamber, and the inner wall is smooth."

Li Shouhan, who had been observing the whole process for a long time and witnessing the whole process, nodded slowly, expressing satisfaction with the set of testing rules and regulations and technologies of the gun station.

"What else to check?"

"Back to the lord, before the official storage, there is still a real yàn. Because we have no way to measure the chamber pressure you mentioned, we have to use the stupidest method. "Ling Li, who has grown into the main force of artillery technicians, methodically returned his methods to Shouhan.

"The cannon cast, after all kinds of testing links, moved to the test artillery field, this test artillery field is not the cannon fire test range, but the selection of a remote and empty place, the cannon chamber is filled with gunpowder, not the gunpowder of one-third of the weight of the bullet when fired in the army, with a long heart to lead the fire rope a little, everyone as far away as possible to hide, once the cannon is fired over the air, the fall is not bad to not explode as the degree, there will be no trouble."

Only those that have undergone such destructive tests can be officially entered into the formation sequence as equipment. If it is not qualified, it will either be re-cast in the furnace, or it will be marked in an inconspicuous position of the artillery and handed over to the Han Yuan firm for disposal. (Ahem!) Ahem! My hand slipped and I made a typo. This is absolutely not true! ）
