The craftsmen are all action-oriented, and Director Jiao immediately summoned several major craftsmen over, and when he talked about the method of the preheating room, these people were immediately shocked, and the eyes that looked at An He were the same as those of Director Jiao.

These people are experts, and An He is also there. So everyone said a word, and soon got the detailed plan of this preheating chamber, and some of them proposed that when the preheating chamber is heated, the fuel and air are separated. This requires very little fuel, and there is no need to use the saved coke at all, and it is possible to use cheaper coal as fuel. In this way, although a preheating chamber is added, it can actually save a lot of fuel costs, and it will definitely reduce the cost of a furnace of iron.

As soon as this proposal came out, it immediately attracted the appreciation of An He and Jiao and others, and even Duan Lun, who was dozing off on the side, also applauded loudly, don't look at the Ministry of Industry can get a lot of money every year, but there are more places to spend money, so as long as he, the secretary of the Ministry of Industry, hears that he can save money, he will immediately become a hundred times more energetic.

As soon as the plan for the preheating room was completed, Director Jiao wanted to do it himself immediately, but An He stopped him and those craftsmen, and the transformation of the blast furnace was just a small move by An He Liwei, and he mainly wanted to organize these craftsmen and help him get the steel filling method together. After all, what is smelted in the blast furnace is only pig iron, but how to turn pig iron into steel? That's the most troublesome step.

Datang's steelmaking is still fried steel, the so-called fried steel, in fact, is to melt the pig iron, and then keep stirring, as if stir-frying, so that the oxygen in the air and the impurities and charcoal in the pig iron can react, so that the carbon content in the iron is reduced, but most of the steel frying method is wrought iron and low carbon steel, if you master it well, you can also get some more widely used medium carbon steel and high carbon steel.

What Anhe wants to engage in is a further steel filling method, although whether it is the steel frying method or the steel filling method, Anhe only knows a rough idea, after all, he has not specifically learned this knowledge, but has only read this introduction from some miscellaneous books or the Internet. However, even if he knows a little about steelmaking, An He is very sure that he can get the steel-filling method out, after all, he is very clear about the essence of steel. To put it bluntly, isn't the so-called steel iron with a carbon content within a certain range?

If you want Jiao to help them get the steel filling method out for themselves, An He has to let them understand the difference between steel and iron first, so An He had to make a temporary cameo appearance as a chemistry teacher and try to explain it in easy-to-understand language. Of course, An He was not stupid enough to talk about any atoms and molecules, but just told them that this iron contains many impurities, of course they know about this Jiao, and then An He said that one of these impurities is very special, and its content will affect the properties of iron.

Everyone understood this, and then An He talked about the principle of the steel-filling method, although the steel-filling method was available in the late Han Dynasty, but it was not until the Song Dynasty that it began to be used on a large scale, so in the early Tang Dynasty, there were extremely few people who knew this steel-making method. In fact, the so-called steel filling method is to mix pig iron and wrought iron together, as long as the ratio is correct, the steel will come out. Of course, the steel filling method is certainly not as simple as Anhe imagined, but the principle is not wrong, as long as you spend some energy and time studying it in this direction. It can definitely get the steel filling method out.

After listening to Anhe's steel filling method, Jiao and a group of craftsmen fell into contemplation, for Anhe's explanation, they also understood, if someone else talked about the difference between steel in front of them, they must have scoffed, after all, when it comes to the understanding of steel, they have played iron all their lives, but no one is convinced. But just now Ann He's opinion on the preheating room. Already let them

I was in awe of An He, a different prince, and now after listening carefully to An He's explanation, and then confirming my understanding of the nature of steel, I found that I only knew what it was before. And where I don't know why, if I explain it with the theory of An He, it will all of a sudden be unblocked.

Director Jiao discussed quietly with the craftsmen around him for a while, and then stood up and reported:

"General Zhonglang, the subordinates have understood the steel filling method you mentioned, although in practice, there may be some problems, but it is not without solutions. If we are given a period of time to study, we are sure that this method will be worked out! ”

"Good!"

As soon as An He heard that there was a door, he was immediately overjoyed, and reached out and patted Jiao on the shoulder twice.

"Director Jiao, if you can get this steel filling method out. It will definitely increase Datang's steel output several times, and you, as the main participants in this matter, will definitely be famous in the history of Datang! ”

"Not bad! You all give me the audacity to do it, come to me when you need it, and you put down everything else at hand during this time. Make every effort to get this steel filling method out. ”

Duan Lun also stood up and said at this time, but the expression on his face was a little strange, and his face was red and didn't look like excitement. On the contrary, it makes people feel a little breathless.

Seeing that even Lord Shangshu fully supported the implementation of this steel filling method, Director Jiao no longer had any worries, and immediately spoke:

"Lord Xie Shangshu supports, and his subordinates will go all out to study the steel filling method as soon as possible!"

Although An He is a prince, after all, he can't control Jiao and them, and Duan Lun is the boss of the family, so here, Duan Lun's words are more effective.

After An He finished explaining the steel filling method, there was nothing for him to do, after all, when it came to the actual operation of iron smelting and steelmaking, he and Jiao were far behind, so as soon as the theoretical knowledge was finished, An He and Duan Lun no longer bothered these craftsmen who had begun to take action, and left the big workshop together.

While walking on the road, Duan Lun snorted angrily and said:

"You kid is really slippery, this is what you said to help us improve the technology of iron smelting and steelmaking?"

"Huh? Isn't a preheating chamber and a steel filling method enough?

This is a good thing that can double Datang's steel production a few times! ”

Ann and blinked his eyes and replied very innocently.

"! Although the preheating chamber is a good way, but your steel filling method is purely a painting cake, and you only know a rough idea, and then talk to the craftsmen, let them study it themselves, whether they can study it for the time being, but it must cost a lot of manpower and material resources, which are all out of our Ministry of Industry's pocket.
