: The second shift of Bu Ri, brothers who have been begging for the elderly, please don't be stingy with your tickets

It's not so much the Pentagon as the Pentagon.

How old is the Pentagon in later generations? How can it be compared with Deng Haonan's Pentagon Castle?

The total area of the twin islands is 400 square kilometers. To the north, the island used for the construction of the Pentagon Castle covers an area of 150 square kilometers. The walls of the Pentagon Castle were built along the pentagonal coastline, two miles apart, with a total area of 60 square kilometers, while the Pentagon of the United States in later times was only 600,000 square meters, a hundred times larger.

Of course, the people's office building is the city wall, but Deng Haonan's is the outer defense of the city wall.

The walls are divided into five sides. The design height is 20 meters, the width is 5 meters, and 10 5,000-pound Longwei cannons and 40 thousand-pound Longwei cannons are installed on each city wall, and 500 people are guarded.

The interior of the castle is also divided into five corners, and in the north corner is the headquarters of Di Haonan, as well as the office administrative area of the major institutions of the Nahao Nan Group, including the martial arts school. The other four corners are the family area, the barracks area, the industrial area and the logistics area. There is a fifteen-meter-wide avenue between the districts, which leads to the outer five city walls, leading inward to the center of the Pentagon.

At the center of the Pentagon is a million-square-meter square, in the center of which Na Haonan is preparing to build a hero's ancestral hall and a monument to the heroes. But those who follow Di Haonan, if they are sacrificed, the tablet will be enshrined and will always receive the incense of the latecomers. And their names will be engraved on the monument. Immortal.

This is just a way for Deng Haonan to win people's hearts. Of course, the tangible benefits that Hao Nan gave them can be supported, but this invisible spiritual incentive is more able to unite people's hearts.

When the Pentagon is completed, it will be able to accommodate 200,000 people. It is enough to solve any of Deng Haonan's current problems.

Build the Pentagon to the north. On the large island in the south, the Hailan base and port facilities were built, and on the mountain more than 300 meters high, fortress batteries were built on the commanding heights of each hill, which were condescending, which could not only protect the warships in the naval base, but also help defend the Pentagon City in the north, and act as horns for each other.

After Huang Zupei and Sigou completed the construction of the Xiaonanshan Naval Base, they already had enough experience. Therefore, the Twin Islands site is expected to be completed within three months, and the internal facilities can only be done according to the needs first, such as prioritizing the completion of the office requirements of the administrative district, and then meeting the housing construction of the family area, and then gradually improving the rest.

Everyone was busy, and Deng Haonan was not idle.

In this troubled world, that Haonan knows what God is!

Artillery!

God of War!

Since Na Haonan came to this world, he has successively manufactured several weights of Huwei artillery and Longwei artillery, and the power is okay, in this era, it is considered a relatively advanced artillery.

However, Deng Haonan was a fanatical artillery expert in later generations. This pediatric weapon made him very shameless.

All kinds of artillery materials in his mind, just take out one at random. It is enough to dominate in this era. It's a pity that the industrial technology level of this era is too poor, even if you want to build a simple cannon for future generations. In this era, it is an unattainable dream. However, Deng Haonan has been working hard!

Yes! He never gave up!

Inside the steel mill. Deng Haonan tried various methods to improve the purity of molten steel and reduce the carbon content. Thus increasing the strength of the steel. It is not necessary to meet the standards of later generations, as long as it can meet the steel standards of the early nineteenth century.

Ming dynasty. Iron-making shaft furnaces and their smelting technology have been further developed. In particular, Fujian metro metallurgy is the most refined.

For this reason, Na Haonan had already entrusted the big housekeeper to the four dogs. and Qian Shun, Zhang Chi and other officials of the Quartermaster Department searched for famous blacksmiths.

It's just that the Ming Dynasty is extremely strict with the control of artisan households, and the taxation is even harsher than the tiger.

The main trick is that the government set up a smelting class, wantonly searched, and aroused strong resistance from the people. In the ninth year of orthodoxy, Fujian and Xijiang silver classes increased tenfold compared with the Hongwu period, and Deng Maoqi and Ye Zongliu rose up one after another. In the ninth year of Chenghua, the Yunnan Patrol said that all the guards in Chuxiong and other places served as miners, because "the frying was insufficient." or pawn wives and children, make up for the number, or even flee for their lives, and gather as thieves." Faced with this strict situation, the Ming Dynasty not only did not take measures to improve it. On the contrary, it has intensified its repression and raids. In the thirteenth year of Hongzhi, it was stipulated that "those who gather more than 30 people and divide mines to more than 30 catties do not care about the first offense and the second offense." Ask the border guards to fill the army".

During the Wanli years, Niu sent eunuchs to various places to distribute extortion. In ten years, he obtained three million taels of silver. The forced struggle against the mining tax has risen one after another. All over the country. "Ming History Food and Goods" talked about the accumulation of disadvantages in the mining administration, saying: "Those who know think that the death of the Ming Dynasty is here." There is some truth to that!

The strictness of the mining tax directly led the mining and smelting craftsmen to change careers one after another, and they disappeared in other places. This poses a stern challenge to the Quartermaster Department. At the same time, in order to cope with the border war, the imperial court had a strong demand for firearms, and allowed each state capital to smelt and cast firearms on its own, so a large number of blacksmiths were confined by the imperial court to various military bureaus. Those who are outcast are even more powerful and powerful. and the merchant gang who forged artillery without permission to take it away. Therefore, the well-known blacksmiths of Fujian are nowhere to be found.

Thereupon. The Quartermaster Department then expanded its scope and went to Nanzhili to search for craftsmen.

After some efforts, it happened to catch up with the boss of Nanjing Longjiang Shipyard offended the eunuchs, the blacksmith workshop was implicated, some blacksmiths for survival, secretly dived and escaped, happened to run into the battleship of the quartermaster department on the river, Yu Minglu and Liu Weiran were worried about not finding a superb blacksmith, and saw that more than 20 people rescued were blacksmiths from Longjiang Shipyard. And talk about the steel mill... Bamboo gnawing

At first, these blacksmiths didn't understand Na Haonan's steel mill, until they got used to one. A few months later, I learned that assembly line production technology was used here. It's just that Deng Haonan also groped for it, and his steelmaking is based on later book knowledge, which is very different from this era.

So, on the one hand, these blacksmiths lamented that Di Haonan's advanced technology can make steel on a large scale. On the other hand, in terms of details, Deng Haonan's steelmaking plant was boldly reformed.

Fortunately, Deng Haonan is very talkative, which makes these craftsmen suddenly bold, and many things that they originally wanted to do but didn't dare to do. At this time, they were all taken out.

Na Haonan knows. Everything has to be tested to know if it works.

It is also necessary for modern people to look down on the ancients and say that they are stupid. But let's take iron-making technology lightly. The advanced ductile iron technology invented by the British promoted the world steel revolution, and the Chinese were amazed. Because until today, China has not been able to do the special steel for aircraft carriers produced by the West, and the timetable for building its own aircraft carriers has been delayed again and again.

But. When archaeologists excavated cast iron tools from ancient tombs in the Han Dance era, they were shocked to find that the use of those tools was comparable to the modern ductile iron process.

How can this be explained? Will you still laugh at the ancients?

That Hao Nan shook his head affirmatively!

Inside the steelmaking plant, Master Li, from a family of Wuhu iron smelters, is helping to improve steelmaking methods. From the use of materials to the final forging and forming, we have provided guidance one by one.

Of course. persuaded the old man to take out the family heirloom, but Yan Haonan struggled with his tongue and thoughts.

However, Di Haonan has no regrets. Because of his huge dedication, he has been rewarded handsomely.

"The iron furnace is one foot and two feet deep, two feet and five inches in front, and two feet and seven inches in the back. Left and right are one foot six inches, the front is a few zhang for the place of iron, all stone masonry, with a simple thousand stone as the door, the bull head stone as the heart, and the black sand as the foundation. Stones are the support. Apply it from time to time, use charcoal fire, put two sheath fans, and get iron four times a day. The wonder is that the stone is produced at the water gate, and the color is red and white, slightly like a peach blossom. The big ones are like solutions, and the small ones are like fists. Mash it and crush it. If it is cast into the flame, it will turn into water. If the heart of the stone is dry, the sand cannot be lowered, so the sand will be sold into iron

The stone that is as colored as a peach blossom here should be a fluorescent stone. It can be used as a flux to lower the melting point and make the furnace condition go smoothly. It is an important progress in ironmaking technology at the end of the Ming Dynasty.

Most of the blowers used in ironmaking are double-acting piston wooden bellows. Due to the clever setting of the box structure and the valve, the air can be supplied in both forward and reverse strokes. Provides continuous air flow to the furnace. The large wooden bellows pulled by four people, with a wind pressure of up to 300 mm Hg, was an advanced blower equipment in the world at that time.

Of course, Deng Haonan's steelmaking plant uses "locomotives, i.e., dump cars fixed with pulleys and rails." For example, the iron yard is filled with ore and thrown from the mountain by locomotive to the furnace, which saves labor. Improved ergonomics.

Coal was shipped from Shandong. Na Haonan disposed of it. It is used as coke for ironmaking.

This is all recorded in Master Zhao's family heirloom secret book: "Coal is produced everywhere, and the mystery burns and closes it into stone, and then chisels it into the furnace and says that it is a reef, but it can not be extinguished for five days." Frying ore and boiling stones, it is very labor-saving

According to the ash content of charcoal, it is only 10,000 yuan, and the sulfur is very little, but it can be ignored, and the porosity is large. The material column has good air permeability, which is conducive to melting operation. But due to its low strength. The furnace height cannot be more than ten meters high, which limits the development of the blast furnace. There are many impurities in butterflies, and the amount of slag must be increased when making iron, and the thermal stability is poor. It is easy to make the furnace condition unsmooth. The resulting pig iron has a high sulfur content. The quality is inferior. Coke is distilled at the time of preparation. Removing most of the volatiles, it has high strength and high calorific value, which is an ideal fuel for shaft furnace ironmaking. After the Sui and Tang dynasties, iron frying was almost the only method of preparing wrought iron from pig iron, so it played an extremely important role in steelmaking. There were three kinds of iron-frying furnaces in the Ming Dynasty: earth hearth, reverberatory furnace and raw and cooked iron-making furnace.

In Master Zhao's words. Na Haonan did adopt advanced methods that had not been used by the ancients in steelmaking. However, in Master Zhao's eyes, the steelmaking plant built by Na Haonan is still a simple hearth. Merely. Deng Haonan magnified it more than ten times, and the layman couldn't see it.

Na Haonan was ashamed of what Master Zhao said, but he couldn't deny it. After all, human capabilities are limited. People who know everything are basically people who are loose in everything. Deng Haonan can make the steelmaking plant to this point, which is already the limit. After all, his specialty is not steelmaking. It's just a matter of getting the best steel.

Compared with the simple hearth, the reflex iron stir-fry furnace improved by Master Zhao for Na Haonan is more advanced. Its combustion chamber is separated from the melt pool to reduce the mixing of ash and impurities. Coal can be used as fuel.

The secret book of the Zhao family records: "If wrought iron is made, when the pig iron flows out, it is connected to a few feet and a few inches lower, and a pond is built, and a short wall is against it." Its iron flows into the pond. Several people lined up on the wall with willow sticks. Dry in the sludge first. Sieve the fine Luo Luo like noodles. One person hurriedly scattered, and everyone stirred the willow sticks quickly, and immediately fried the mature iron. Every time the willow stick is fried, it is burned two or three inches. Reuse. and even more. When it is slightly cold, there are those who cut it into squares in the pond, or those who propose to wave the spine to round the goods

This practice of using the iron-making furnace and the iron-frying furnace in series to improve production efficiency and reduce energy consumption is very advanced in terms of process thinking.

Master Zhao was very fond of Na Haonan and always explained to Na Haonan in detail. Merely. Deng Haonan really had a headache about the ancient text, so he could only pretend to listen very seriously.

Of course, the people next to Deng Haonan carefully recorded them one by one.

"Where the iron furnace is made of salt and mud to beg out of the oven and not fried for pig iron, it is both fried and cooked, and the raw and cooked phase refining Zhou Yuxi wool iron, raw rotten iron. When the stream is ripe, he also makes Fang Zhijun "sprinkle dry plaster and hold a willow stick to stir quickly, then it is cooked." ”

This process of smelting wrought iron is still used in Sichuan, Yunnan and other places in modern times.

Filling steel is the most important in all kinds of traditional steel-making techniques, wrought steel has no source, it is made of pig iron and wrought iron, or wrought iron sheets are sandwiched in a wide iron pot, and mud is coated into the fire. or cast with pig iron and wrought iron. Wait for it to be very familiar. If the pig iron wants to flow, the pig iron is placed on the wrought iron and rubbed into it.

Changing the wrought iron of the bending plate to iron sheet can increase the contact area of raw and wrought iron, which is conducive to slag forming and carbon diffusion and homogenization. The infiltration of the pig iron droplets on the raw iron helps to make slag and purify the iron. It is similar to the principle of modern Bailin steelmaking.

Master Zhao's improvement of Deng Haonan's steelmaking plant brought a new dawn to Deng Haonan's steelmaking plant, when the first furnace of molten steel was locked, Na Haonan checked it, and it was indeed more than twice as good as the steel he had made before.

No wonder the British scholar Stevens once said: "The Ming Dynasty is a great country!" Even in his last days, he still exudes his strength! Anything that Europe can make. As long as the Ming people have seen it. It can be imitated immediately and quickly put into mass production! And whether it can be mass-produced in a short period of time. is the standard of a strong country".

Of course, the facilities in the steel mill are also guided by more than 20 other steelmaking masters. In general, the biggest beneficiary is Deng Haonan.

However, Deng Haonan was not beaten by Master Zhao and was powerless.

In the days that followed, Di Haonan began to collect rare metals, mainly tungsten steel and manganese steel, which were used to enhance the strength of steel, because Na Haonan needed to make a forging mill from this steel in order to lay the foundation for large-scale industrial steel processing in the future.

There is also silicon manganese steel, which is used to make springs. There are also key steels that resist high-temperature friction, and the most important is inlaid steel stainless steel. Because of its strength. Strong corrosion resistance. It is not easy to oxidize, which is the best material used by Deng Haonan to cast artillery.

It's just that the materials that Deng Haonan needs are very difficult to find. For example, inlaid ore needs to be transported all the way from Yunnan. Yunnan's inlaid ore has existed since the Song Dynasty, because another name for inlay is fake copper, which is often used by merchants and landlords in Yunnan to make fake copper coins. When Deng Haonan learned about it, he scolded these businessmen for being too extravagant. As everyone knows, that thing is a very important steel raw material.

The Quartermaster Department traveled thousands of miles to contact Yunnan fake copper mining merchants. Shipped back to the inlay. Then Na Haonan used the method of reducing the red inlay ore with charcoal to make metallic nickel, and finally fused it into molten steel to obtain a very shiny stainless steel.

This thing was undoubtedly a huge blow to Master Zhao and the others, and their arrogance suddenly disappeared. Thereupon. Deng Haonan told the craftsmen that adding a small amount of other metals to the steel would give them a variety of steels, and let them study it. After all. Deng Haonan on this. I don't know the name of minerals in the world, and I don't know the number, so naturally looking for rare metals is like looking for a needle in a haystack.

However, if they let these experienced craftsmen study, with their experience and experience. It should be possible to find the metal element that Di Haonan is looking forward to. As long as they practice the steel that meets Deng Haonan's requirements. Deng Haonan can clearly know what the name of this metal is in Daming. This can then be used for large-scale mining. And the production of such steels was carried out.

Oh, my God! Di Haonan is actually ready to train these craftsmen to become scientists!

After that Haonan smelted the inlaid steel. The surplus was used to make artillery.

When the first test artillery was built. Everyone was stunned. Because after the artillery is polished and polished. It becomes very bright. A refreshing metallic glow in the sun.

Compared to the previous cannon, it was still bright after being polished, but it didn't take long. It becomes black and looks ugly.

That's the effect of stainless steel!

Of course, stainless steel is only within a certain range of dù is not tempting!

The first artillery gun made of nickel steel. Na Haonan called it the Apocalypse Five-Year Young Millimeter Old Double-Diameter Front-loading Cannon. The basic parameters are: caliber drop millimeter, old double diameter, muzzle velocity about meters, seconds, effective range: live ammunition Xu Mi corpse shotgun Gammy, bullet weight: live ammunition 4 kg corpse shotgun 8 kg, rate of fire corpse cent, gun car weight inkstone kilograms.

And the previous Qianjin Longwei artillery must have used artillery made of hawium steel. The firing range was longer, the weight was lighter, and the barrel became longer.

Apocalypse five-year field millimeter cannon. Western artillery of the same type was a six-pounder cannon. This means that their fired shells weigh about the same. However, in terms of range and power, as well as the weight and overall performance of the gun, the Western six-pounder gun could not be compared.

Because Deng Haonan only built a small-caliber artillery gun with the mentality of experimentation, the result was very successful. But. This artillery is still too small to be installed on a warship. So Deng Haonan improved the gun carriage and turned him into an army-type cannon, equipped with marines.

After it is determined. The arsenal began to produce modified artillery according to Deng Haonan's request. According to Na Haonan's request, the first batch of artillery to be equipped with the Marine Corps was produced with 100 pieces, and the Marine Corps was specially equipped with 500 artillery pieces.

In this way, Di Haonan's marines are no longer just fighting with muskets with battleships, but can be used as an independent unit to land on the beachhead!

This is a huge step forward for the Na Hao Nan collective.
