Lin Xi said:

"I'll give you an idea.

Make sixteen crucibles of fine iron, each containing a hundred and forty pounds of brass, and make two lugs for the crucibles, and put an iron lid on them;

The lug is connected to a crossbar by means of an iron rod, and the crucible can be moved and hoisted by means of a fixed pulley;

The iron lid can be lifted to clean up the scrap copper and dross, and the oxidation of the copper will be much slower after the lid is closed.

Make a groove lug at the bottom, which can be lifted with an iron hook, tilt the crucible, and make a triangular diversion at the inclined place.

You have to make a mobile bracket so that each crucible can be easily moved and moored to the corresponding sprue.

The melting furnace is also very important.

In my opinion, the location of the melting furnace should be no more than a zhang away from the model of a submarine.

This necessitates a change in the construction of the melting furnace.

You see, basically eight crucibles are arranged into a sixteen palace array, above the sixteen palace array, arranged with iron square pipes, arranged into a rough cage, one end stretches out some, you can draw the air in the atmosphere, and then a long section, directly added to the crucible fire, so that the cold air will be heated by the hot air above the crucible, and then through the centrifugal air jet that drives the impeller with an electric motor or windmill, from the bottom of the furnace, blowing to the coke, the coke is 2 and a half feet thick, you can try to fine-tune it in the future, neither is it enough, Don't waste too much either.

Wait until the copper melts and emits a white appearance, open the air heating pipe above, one upper casting mouth per foot, two side casting openings, and one side casting opening at each end, so that there are eight side casting openings in four feet, plus ten side casting openings at both ends, and another four pouring openings at the upper end.

Ten sprues on both sides can be cast almost simultaneously.

Then connect the air inlet of the axial flow blower to an air inlet at the top.

When casting, first plug the above four pouring ports with plugs, and then pump the air strongly, so that the pressure of the gas in the model cavity will be reduced, forming a low vacuum casting, which can reduce the generation of bubbles, if done well, even the bubbles in the copper juice can be extracted, but now it is impossible to do. ”

Lin Xi handed the finished drawings to Liu Ziming and them to see.

Everyone watched it for a while, and Lin Xi asked Lu Xin: "Master Lu Xin, Master Liu Ziming, what do you think of this method?" ”

Luxin Says:

"The gift of the saint is really incredible, ingenious!

But of course, there must also be these magical utensils, the method of coke preparation, the method of coke combustion, the method of air heating,

The atmosphere of a sheep flower bed you mentioned (note: carbon monoxide is still too difficult to understand for Luxin, so it is easy to say that it is something that you can remember) (Note: The reducing atmosphere refers to the fact that copper is in a gas environment with a high concentration of carbon monoxide produced by incomplete combustion of coke during the melting process, and in this atmosphere, copper is not easy to react with oxygen, so as to maintain pure copper. ),

There is also the frame structure just now. ”

After Liu Ziming saw it, he had an irrepressible excitement:

"Today, after looking at this design, I think, maybe you can also improve it, in fact, after the casting, the furnace and the crucible are hot, if we can cast two ships in a row, it will save at least half of the time, save more than one-third of the fuel, if we cast three ships in a row, we can complete it within two days of the amount of work of separate casting."

Lu Xin asked, "Are the two models side by side?" ”

Liu Ziming said: "No, you can follow the shape of a chrysanthemum. ”

Lu Xin asked: "If you go from a cold stove to refining copper juice, how long will it take?" ”

Liu Ziming said: "If you pull the bellows, in three or four hours, maybe the windmill or electric fan mentioned today will be shortened?" ”

Lin Xi said: "Build a few more windmills, convert them into electricity, and use electric fans to increase the wind power of the most powerful bellows by ten times, so the shortening of time is not the bellows, but after the hot air blows carbon, between the generation of heat and being taken away by the wind, how much wind is the most suitable." ”

Liu Ziming took a breath and said, "If that's the case, two hours and one furnace is nothing?" ”

Lin Xi remembered the intermediate frequency electric stove and said: "At present, this is far from being the fastest and cleanest, but because of the things that you couldn't imagine before, maybe it can be completely melted in an hour, and it will take an extra hour for the cold stove to be heated." ”

The Qingxu Pope said in surprise: "If this is the case, six hours during the day a day, and the cold stove starts to burn at dawn, and five ships can be cast in a day?" Exactly 10,000 catties! ”

Lin Xi said: "If you continue to cast, the coke needs to be filled, and it will take a little more effort, and you need to use a special carbon hopper, which can be opened and closed, and move to the stove through the row frame structure, and the excess coke ash will be blown away by increasing the wind force, and the other will be dredged by iron rods." ”

Lu Xin said: "If you dredge it through an iron rod, there is still a standing position for people, whether the dredging is appropriate, I think, it is better to blow the ash in a strong wind, that is, people should be far away, and it is better to be on a certain earthen platform along the coast." ”

Liu Ziming said: "Yes, this is exactly the reason. But we don't have enough supplies, and we can't rely on the reserves of eagle's beak rocks alone. ”

Tu Xicai said: "We will solve this with the Xuanyi Army!" Before sunset tomorrow, we will at least take Minami Okura. ”

Pope Qingxu said: "Marshal Tu, our Gospel Department has detected the location of all fourteen warehouses in Yashan, and there can be more than one million catties of copper, which is the entire family of the Great Song Dynasty, and there are also some officers' private collections. ”

Tu Xicai was overjoyed: "Qingxu Zhenren, since you have already detected it, why don't you say it?" I won't give you this drink. ”

The Qingxu Pope was happy: "It's not a secret, the fourteen cancangs were not detected at one time, we sent someone to enter the southern canatura, who knows, among the fourteen canaries, in fact, the ones that belong to the Great Song Dynasty have long been hollowed out." On the night when the puppet yuan landed on the shore, all of the fourteen except for the eagle's beak rock belonged to the private army. Except for Nan Dacang, the other twelve belong to two forces, and they have all besieged the city with earth, ready to play against the Xuanyi Army? ”

Jiang Chen couldn't help but scolded hatefully: "A bunch of nests! ”

The Qingxu Pope said: "Since there are only three forces, it is much easier to investigate, and they are each pulling heads, of course, they must measure the resources of each family, and strive to win over the soldiers and generals who can fight." Jiang Lifu of Nanokura is very important, and now there are fifty or sixty guards in and out, hahaha"

Liu Ziming's eyes lit up: "They recruited soldiers, and the food, silver, weapons and tools needed to defend the city, copper is not of much use, so it is not very good at loss, right." ”

Pope Qingxu smiled and said, "Yes! A bunch of dying people can't be fed! ”

Lu Xin said: "Well, they defend the city, if they need to make utensils, they need a master craftsman, and in the absence of a master craftsman, they can only do very little tinkering, well, they really don't know whether they are alive or dead." ”

Lin Xi said: "Gentlemen, I've gossiped, let's finish the submarine matter first, I'm also curious about the information of the Qingxu Pope, this is a big opportunity." ”

Everyone looked ambiguous, and even some people had water flowing down, which was really uncontrollable.

Lu Xin cleared his throat:

"Well, that's what I see about things, let's build a few groups, anyway, there are a lot of soldiers now, let's do it;

The first is the coke group, the second is the crucible group, the third is the furnace group, the fourth is the electric windmill group, the fifth is the electric hair dryer and exhaust unit, the sixth is the valence structure group above the furnace, the seventh is the hopper group above the valence structure, the eighth is the model group, the ninth is the model auxiliary material group, and the tenth is the casting technology group.

The eleventh is the mine group;

The twelfth is the torpedo group;

The thirteenth is the communication equipment group;

The fourteenth is the grain and logistics support group,

The fifteenth is the medical treatment group.

Set up a general headquarters for the submarine project, with a general commander and commanders of each group;

Each group has a commander, a master craftsman, and 100 to 200 sergeants are assigned to help with the work, 3 scribes join the army, 3 spies, 3 signal soldiers, and small workers and auxiliary workers are recruited by master craftsmen.

The Pope of Purity set up a group of scribes and detectives;

Marshal Tu set up a security and anti-spy group;

To obtain raw materials, Marshal Tu is responsible for this. ”

Tu Xicai said: "Master Luxin really has the style of a famous general, in addition, you have to be under the eagle's beak rock, we will set up a cordon two miles away to ensure the safety of the project." ”

Liu Ziming shook his head: "Marshal, the submarine is going to go to the sea, it can't be in Eagle's Beak Rock?" ”

Tu Xicai said: "The left and right are only two thousand catties, and they have been lifted." ”

Lin Xi said: "Security is the foundation of everything, and you must especially do a good job of confidentiality. ”

Then, Lin Xiyou drew a picture:

"I just thought, since we already have a row frame structure above the top of the furnace, why can't we make a model of four or five models of the submarine above-ground row frame structure, so that as long as we move the cast model, and then move the model next to it, in the same position, casting, must improve the skill of the caster!"

Lu Xin looked at the picture and praised it: "Yes, this idea is so good, I understand, we must do everything possible to make things easy to do, not to look good and difficult to do!" ”

Several people next to him said, "That's such a reason!" ”

Lu Xin put away his things and said to Lin Xi and the others: "Today, the marshal, the Pope, the principal, the matter is urgent, and the workload is very large, I will wait for this to go down and make arrangements." Also, be sure to invite the Song Academy to come over, our entire engineering institute combined, there are no more than 200 masters, each of which is precious. ”

Jiang Chen said: "Commander-in-Chief Deer, don't worry, I will raise horses and take over all the masters on the Xuanyi tonight, you go and arrange it first." ”

Lu Xin nodded, and instructed again: "Marshal, copper, iron, charcoal, and bamboo and wood, please." After saying this, they bowed deeply, and everyone bowed to each other.

Xiao Bing said very obediently: "Today, it's time to eat." ”

Lin Xi said: "Very good, I'm hungry." ”

As soon as the meal was served, someone at the door reported that Lin Xi raised his chin to Xiao Bing, Xiao Bing understood and immediately went to the door.

After a while, he came back and said: "There is a man named Jiang Lifu, who says that he is Nan Dacang, and he wants to surrender?" ”

Tu Xicai hurriedly asked, "Is he alone?" Or the whole Minami Okura? ”

Xiao Bing said: "He said that Song Bing, who represented Nan Dacang, came to negotiate peace and talk about the conditions for peace. ”

The Pope said, "Now, let him come in and talk about it?" ”

Lin Xi ate and said, "Okay, let's talk." ”

Tu Xicai said, "Then let him in." ”

Xiao Bing said: "He has a hundred personal guards. ”

Tu Xicai said, "Well, you can bring two people in." ”

Xiao Bing said: "Obey." ”

After a while, Jiang Lifu came in with two men with big shoulders and round waists, and made a salute, which was not respectful, nor disrespectful, Jiang Lifu said: "Ladies and gentlemen, Nan Okura commanded me to ask you to say goodbye, and came in the middle of the night to negotiate peace, so as not to ruin the lives of people." ”

Lin Xi asked, "What about the conditions?" ”

"Well" Jiang Lifu thought to himself, this is not according to the routine, so he said stubbornly: "My family said that we will take out one-third of the grain to the Xuanyi Army, after all, they are all Han people, and it is the right way to resist the enemy together." In addition, my family commander hopes to exchange some flying and explosive artifacts with the Xuanyi Army, yes, there are also aerial water-making artifacts, we can buy them, silver and food. ”

Lin Xi said: "The people who took you go back now, before the time of the child, I want to see the copper and copper coins, iron, charcoal and bamboo wood in Nandacang, which can surround you from dying, and you can leave some private property, you can stay in Yashan, or you can leave Yashan." ”

Jiang Lifu still has three points of anger, and immediately said softly and firmly: "My lord, killing people is not enough, but I have more than 10,000 soldiers in Nan Dazang, and the soldiers are full of food and drink......

Lin Xi said: "It's time to talk about anything." It was not delivered, but it will be delivered tomorrow morning, and you will be allowed to leave Yashan with the silver you have saved, not exceeding a certain amount. When the sun comes out tomorrow, we will destroy all the southern okura, and we will take it ourselves! ”
