"The blast furnace of 10,000 jin will take longer. The technology is not mature at present, and it will take at least two hours. The blast furnace will not stop day and night, and can only produce four furnaces. This is the fastest speed." Zhang Tan said helplessly. What restricts the smelting speed is not the temperature. After the orange charcoal is present, the heating will rise very quickly. As long as the amount of loess is reduced in the fuel, it can be quickly humidified.

But the 10,000 kilograms of furnace is too heavy. The 10,000 kilograms of molten iron plus the weight of the blast furnace itself is definitely not possible to use a crucible like before. The high temperature of more than 1,000 degrees and the 12,000 kilograms of furnace body molten iron is too high to pour out.

Therefore, Zhangtan uses the trench-release method. The blast furnace is fixed. Below the blast furnace, a switch like a water pipe fence is reserved. After the molten iron in the furnace is smelted, turn on the switch and let the molten iron flow into the placed mold by itself along the iron groove.

It seems easier?

Stop pulling it, it’s convenient to use crucibles. When smelting, after high temperature heating, the impurities will float on the upper layer of iron because of their light specific gravity. When smelting with crucibles, just stand on a high place and use a long-handled iron spoon to remove the miscellaneous spoon floating on it.

The blast furnace obviously cannot be used like this. Standing at the feeding port, even if it is tens of meters away, tens of thousands of kilograms of molten iron emits heat, no one can withstand it.

Therefore, the filtering method can only be used. This requires that each time the material is poured, a filter mesh is installed at the switch below. The melting point of this filter mesh is higher than that of molten iron. Renault chose a tungsten wire mesh, which has a pretty good effect. Thanks to the ultra-high temperature of the tangerine, the melting point of tungsten with a melting point of more than 3,000 degrees, at the high temperature of the tangerine, it is not more troublesome than smelting iron ore.

Every time you clean the chamber, refractory bricks, install filters, and feed materials layer by layer, it takes much longer than using a crucible, which makes the smelting speed of 10,000 jin furnaces not faster.

"Four furnaces a day?" General Wei moaned. Wei Wenchang, who would not frown even if his bones were broken, was thundered by Zhangtan. You produce four furnaces a day, and one furnace produces ten thousand kilograms. This is 40,000 kilograms of fine iron. You still look dissatisfied with desire. Is this appropriate?

After thinking about it, he understood the difficulties of Zhangtan. Before he could get here, he heard that Master Lei had a crazy plan for the city of Jing Iron. He naturally did not believe it, but Master Lei was unpredictable. With the idea that he would rather believe in it, he hired a master of mathematics and asked them to calculate how much Jing Iron needed for a city of Jing Iron with an area of ​​ten miles.

As a result, the questions asked by General Wei stumped all the mathematical studies in Dachu. For more than a month, until he set out, he could not give an accurate result.

Anyway, it takes a lot of money. All the fine irons in Dachu are transported here in a year, which is enough to build a few rooms.

Come here and see that the plan of the Jingtie City is not only true, but also has a certain foundation. Within a radius of several miles, the ones that are stepping on are all five centimeters thick. How much fine iron is there? Take it out enough to equip Da Chu and then equip a million troops, and just spread it on the ground?

What's even more exaggerated is that so much fine iron is only part of the smelting. It is said that there are also a large amount of alloys cast into metal ingots for processing weapons, daily necessities, and experimental purposes.

For the Shengong Hall Craftsman Camp, these things are just ordinary goods. Apart from export goods such as casting iron pots and kitchen knives, they do not use them.

Of course, there are more than that. When he saw nearly a thousand hydraulic crushers standing by the underground river, the coolies took hydraulic drills and took materials on the spot to mine iron ore, threw them directly into the crushed stone crusher, and then followed the hydraulic conveyor belt to pass the crushed small pieces of ore to the edge of the iron grinding. The hydraulic power drives a huge iron grinding and grinds the ore to the size of sand.

Then it continues to be transported to the mine washing pond. After cleaning, the clean concentrate ore powder is transmitted through hydraulic power and is directly transported to the smelting site on the ground.

During the entire mining process, Renault used this huge underground river to the limit, otherwise his manpower would not be able to support such a large smelter.

Although a furnace does not use much iron ore, Zhangtan wins by quantity. Hundreds of small blast furnaces are discharged for more than ten miles and filled once, which can consume millions of kilograms of ore powder.

And this is not once a day, but more than five times a day. Zhangtan used the method of ants gnawing bones to turn the workshop-like small blast furnace into a cluster mode, and forced the output to the level of small steel plants on the earth.

Tens of thousands of people work for a day and can smel out almost 500 tons of refined iron. This amount is scary. Even if it is less than 200,000 tons in a year, there are always 170,000 tons or 80,000 tons.

Moreover, this number will continue to increase. At present, the blast furnaces are not entirely restricting production, but human resources. Airships are transporting manpower from all over the place to the camp. In a few months, the population of the camp has doubled, infinitely close to 20,000.

The new blast furnace is to solve the problem of insufficient human resources. You must know that people alone are not good, but they also have to solve the most basic living problems. Food alone will cost human life. You cannot grow food in the rainforest, and people cannot live by eating fruits.

Smelting is a high-temperature and high-risk physical work, and it is necessary to ensure sufficient nutrition. Seventy percent of the airship troops in the Shengong Hall are used to transport daily necessities, including food and meat.

As the load capacity of the airship increases, for everyone's sake, not only are jerky meat, but also live cattle and sheep transported here. If it weren't for a suitable boat, Renault would also supply a large amount of sea fish, which is very close to the beach.

Since Wei Wenchang boarded the airship, he was shocked, shocked, and shocked again...

Until now, he had not come back to his senses. Zhang Tan held paper and pen, wrote and painted, and said something he didn't understand at all. The final conclusion was that according to the current smelting and upgrading speed of the Shengong Temple, this city of Fine Iron can be built in at most five years, and the speed is no slower than that of brick, stone and wood structures. After all, this is a big city with a side length of more than ten miles.

Of course, for Zhang Tan’s bragging... Niu, oh, Niu is definitely not enough for him to brag, he has to brag Peng Whale.

Because there are still several conditions in his conclusion. Within two years, the smelting workers will reach 300,000, and the blast furnace efficiency will be increased ten times. In the eyes of General Wei, aren't you bullshit? You can't do it at all, okay, there is no problem with people, but the efficiency will be increased ten times?

In the same time, one furnace smelted out 100,000 kilograms of iron, how big is your furnace?

"General, please go here. This is a musket workshop. It can mass-produce the Shengong One-type muskets, and produce fifty ones a day. As the laboratory conquers the spring project, as long as the hydraulic drilling machine can be successfully experimented, the output will increase ten times." Zhang Tan said proudly.

Outsiders really don’t know about muskets. After all, the number is small, most of them are sent to the resource camp. Several musket teams left in the camp were all sent to the underground world to hunt, and there was no place on the ground at all. Not to mention outsiders, there were never seen coolies later, so Wei Wenchang didn’t know that there were too many war weapons in the Shengong Hall.

"Oh! What is this musket?" As a soldier, he intuitively believed that a musket that he had never heard of before was probably a weapon.

Wei Wenchang is still looking forward to the weapon developed by the secret technique of Lei Shi. The pressure on Chu was very high. Chu Ren had taken a year and a half to master most of the voice in the court and the support of the military. This is also thanks to King Wu for his outstanding support, otherwise Chu Ren would not have been able to sort out the internal affairs of the Great Chu so quickly.

Although the government orders are basically clear and the Wu Palace rarely cooperates with the Emperor Chu, there are too many problems in the Great Chu, and even the people's food and clothing have not been solved. The issues such as expanding the army, armed forces, training, and increasing naval warships are still on paper. Especially the problem of naval army expansion can not be done in a short period of time. Not to mention that the Great Chu has no money, even if it has money, warships are not something that can be created.

In the army, the military headquarters has three times the expansion. Now the expansion has been completed, less than one-third, and the number of new recruits has reached 800,000, but only half have complete soldiers.

As for the heavy cavalry that the generals wanted most, the expansion of the army was less than 20,000. In the Great Chu world, heavy cavalry was a tank, which not only required excellent equipment, but also had the best war horses, and even had very high requirements for personnel.

The full set of vests, heavy armor, and weapons together exceed 200 kilograms. Even if you ride on a horse, the burden on the knight is not light.

The heavy cavalry does not allow you to stand still with heavy armor. You need to wave your weapons to kill. Without the strength and endurance of a warrior, you can't hold on for long.

Not all warriors can become qualified heavy cavalry. It takes at least two to three years for a heavy cavalry to be selected to form an army.

It is obvious that the Ao people would not give Da Chu so long. Da Chu City had all withdrawn from Da Chu six months ago. Now there are less than two thousand people serving him and hundreds of fast ships to convey intelligence.

The first fleet of the Ao people arrived on the Romon Islands three months ago, and there are as many as eight flag numbers found.

The military system of the Austrians is different from that of the Great Chu. It is not based on the army, but on the army, with each army of about 30,000. In other words, the Austrians have been discovered so far, with eight armies and 240,000. There are 1,200 warships and nearly 1,200 transport ships.

In addition to the Eighth Army, there are three times the number of civilians. Now the total number of Austrians on the Romon Islands is close to one million.

The strength of the Dachu navy was very average. The two navy soldiers had less than 2,500 real warships, which were about twice the number of the first fleet of the Ao people. Both the tonnage and quality were quite different.

No one believes that this is the full combat power of the Austrians. It is very slow to build warships, and Chu Ren cannot afford to lose money. In addition, the six armies do not understand water warfare. The military headquarters believes that it is better to defend than attack. If you want to take advantage of the Austrians' foothold, you will have a light battle. Even if you win, the losses of the Great Chu will be very amazing.

The sea station is different from the land war. One thing is that the entire army is wiped out, and Da Chu really can't afford to play.

In other words, Renault didn't know, otherwise he would definitely sneer. The Great Chu Army did not understand the importance of sea power at all.
