Capital Datang

There is a saying that "one sentence wakes up the dreamer." Li Yin's seemingly joking words were heard by Mr. Jiao, but it was like a thunderbolt, which blasted a gap in his already fixed thinking. Li Yin's metaphor was very vivid, and he immediately grasped the key point, and said excitedly: "Your Highness, do you mean that the air can be heated and then blown into the furnace? "

"Hehe, Mr. Jiao really has rich experience, and he grasped the key point at once!" Li Min praised, the air preheating is actually a layer of window paper, everyone understands the truth, but no one has ever thought of doing this, the main reason is the former Human experience limits their thinking.

Li Min stepped forward and walked to the side of the water drain, stretched out his hand and gestured on the ground: "Uncle and Mr. Jiao, please look, you can build a pre-heating chamber here, and heat the air and blow it into the furnace." , In this way, the temperature in the furnace will not drop due to the cold wind, and the higher the furnace temperature, the faster the iron in the iron ore can be smelted, which not only saves time, but also improves the quality of the smelted iron Much stronger than before."

As the minister of the Ministry of Industry, Duan Lun still has a superficial understanding of the art of iron smelting, so he can understand Li Yin's words, but as an official who takes care of the overall situation, he hears an inappropriate thing from Li Yin's words. He immediately asked: "Liulang, I understand the preheating room you mentioned, but have you ever thought about it? This preheating room also consumes fuel. Although the quality of the iron produced is better, the cost But it also increased, wouldn't it be a little uneconomical?"

Hearing Duan Lun's question, Chief Jiao, who was excited, said first: "Master Shangshu, increasing the preheating room will not increase the cost, because after the furnace temperature is increased, the smelting time will be shortened. Reduce the amount of fuel, and the saved fuel can just be used to heat the air.” Capital Datang 89

"Huh~, wonderful! This is my negligence!" Duan Lun heard Mr. Jiao's explanation.Immediately, he praised Li Yin with bright eyes, and at the same time, he admired Li Yin's talent even more. The quality of the smelted iron has increased, and it can also speed up the time for the furnace to tap the iron.Don't underestimate this little improvement. Datang has countless iron-making furnaces. If each furnace is modified as Li Yin said, not only will the annual iron production increase a lot.Moreover, the quality of the iron can also be improved to a higher level, which is a remarkable feat!

"Liu Lang, everyone said that you were instructed by a god and a man. I didn't quite believe it at first. I just saw it today. Those rumors are not exaggerated for you!" Duan Lun thought that he had obtained such a big one out of thin air. With the excitement in his heart, he no longer cared about his demeanor, stepped forward and patted Li Yin on the shoulder and praised him loudly.

"Where is that, uncle, you praise my nephew too much!" Li Yin hurriedly said modestly, but he couldn't hide the pride on his face, especially when he saw Mr. Jiao's eyes shining with admiration for him, looking at himself It's like seeing a pile of gold and silver treasures.I can't wait to grab him and hold her in my arms and kiss him.

Craftsmen are all activists. Director Jiao immediately summoned several major craftsmen, and when he explained the method of the preheating room, these people were shocked immediately, and they all looked at Li Yin in the same way as Director Jiao.

These people are experts, and Li Yin is also there.So everyone talked to each other, and quickly worked out 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 has very low requirements for fuel, and there is no need to use the saved coke, and cheaper coal can be used as fuel.In this way, although a preheating chamber is added, it can actually save a lot of fuel costs, which can definitely reduce the cost of a furnace of iron.

As soon as this proposal came out, it immediately attracted the praise of Li Yin, Mr. Jiao and others. Even Duan Lun, who was dozing off on the sidelines, applauded loudly. Although the Ministry of Industry can get a lot of money every year, there are more places to spend money , so as long as he, the minister of the Ministry of Industry, hears that he can save money, he will immediately become full of energy.

As soon as the plan for the preheating room was finalized, Director Jiao originally wanted to do it himself, but Li Yin stopped him and the craftsmen. Renovating the blast furnace was just a small move by Li Yan Liwei. He mainly wanted to organize these craftsmen. Help yourself to figure out that iron filling method together.After all, only pig iron is smelted in the blast furnace, but how to turn pig iron into steel?This is the most troublesome step.

Datang's steelmaking still uses the method of frying steel. The so-called steel frying is actually to melt the pig iron and then stir it continuously, just like stir-frying, so that the oxygen in the air can react with the impurities and charcoal in the pig iron. , to reduce the carbon content in iron, but most of the iron and low-carbon steel produced by this method of frying steel are wrought iron and low-carbon steel. If you master it well, you can also get some medium-carbon steel and high-carbon steel that are more useful .

What Li Yin wants to do is a further method of filling steel. Although Li Yin only knows a rough idea whether it is the method of frying steel or pouring steel. Or read about it on the Internet.However, even though he has only a little knowledge of steelmaking, Li Yin is fully confident in the method of pouring steel. After all, he knows the nature of steel very well.To put it bluntly, isn't the so-called steel just iron with a certain carbon content?

If Mr. Jiao and the others want to help them figure out the method of pouring steel, Li Yin must first let them understand the difference between steel and iron, so Li Yin had to be a guest chemistry teacher for a while, and try to explain it in an easy-to-understand language.Of course, Li Yin was not stupid enough to talk about atoms and molecules. He just told them that the iron contained many impurities. Of course they knew about Mr. Jiao. Then Li Yin said that one of these impurities was very special. Its content will affect the properties of iron. If there is too much of this impurity, it will be pig iron, if it is less, it will be wrought iron, and if it is in the middle, it will be steel.

In this way, everyone understood, and then Li Yin explained the principle of Guangang method. Although Guangang method existed in the late Han Dynasty, it was not used on a large scale until the Song Dynasty, so it was not used until the early Tang Dynasty. , People who know this steelmaking method are extremely rare.In fact, the so-called steel filling method is to mix pig iron and wrought iron together. As long as the proportion is correct, steel will come out.Of course, the iron filling method is definitely not as simple as Li Yin imagined, but the principle is not wrong, just spend some energy and time researching in this direction.Absolutely can come up with the pouring steel method.

After listening to Li Yin's method of filling steel, Director Jiao and a group of craftsmen fell into deep thought. They also understood Li Yin's explanation. If someone else talked about the difference between steel and steel in front of them, they would definitely sneer. When it comes to the understanding of steel, those of them who have been playing with steel for almost a lifetime, but they are not convinced by anyone.But Li Yin's opinion on the preheating room just now.It has already made them feel awe of Li Yin, a unique prince. Now after listening to Li Yin's explanation carefully, and confirming it with their own understanding of the nature of steel, they found that they only knew what it was before.And where I don't know why, if I use Li Yin's theory to explain it, it will suddenly become smooth.

Chief Jiao discussed with the craftsmen around him for a while, then stood up and reported: "Your Highness, all the subordinates understand the method of pouring steel that you mentioned. It's not that there is no solution. If we study it for a while, we are sure to come up with this solution!"

"Okay!" Li Yin was overjoyed when he heard that there was a door, and he stretched out his hand and patted Mr. Jiao on the shoulder twice, "Mr. Jiao, if you can come up with this method of pouring steel, it will definitely increase Datang's steel output by several times." Times, and you, as the main participants in this matter, will definitely be famous in the annals of Tang Dynasty!"

"That's right! You all have the courage to do it for me, and come to me if you need anything. During this time, you put down other things at hand. Do your best to make this Guangang method come out." Duan Lun also stood up and said at this time, It's just that the expression on his face was a bit strange, his face was so red that he didn't seem excited.On the contrary, it makes people feel a little suffocated.

Seeing that even Master Shangshu fully supported this Guangang method, Chief Jiao and the others no longer had any worries, and immediately said: "Thank you, Lord Shangshu for your support, and my subordinates will definitely go all out to study the Guangang method as soon as possible!" Although Li Yin is the prince, he can't control Mr. Jiao and the others. Duan Lun is the boss, so here, Duan Lun's words are more effective.

After Li Yin finished explaining the method of pouring steel, he had nothing to do next. After all, when it came to the actual operation of smelting iron and steel, he was far behind Mr. Jiao, so once the theoretical knowledge was finished, Li Yin and Duan Lun stopped bothering these craftsmen who had already started to act, and left the big workshop together.

While walking on the road, Duan Lun snorted angrily: "Liu Lang, you are really cunning, is this what you said to help us improve the technology of iron and steel smelting?"

"Huh? Uncle, isn't a preheating room and a steel pouring method not enough? This is a good thing that can double the steel production of Datang!" Li Yin blinked his eyes and replied innocently.Capital Datang 89

"Fart! Although the preheating room is a good method, but your steel pouring method is purely a drawing, and I only know the general idea, and then I will talk to the craftsmen and let them study it by themselves. Can you study it? Let’s not talk about coming out, it will definitely cost a lot of manpower and material resources, all of which have to be paid for by our Ministry of Industry.” Seeing Li Yin’s scoundrel, even Duan Lun, a gentle man, couldn’t help but swear, When Li Yin asked him for help, he boasted that he was an expert, as if he could get everything done right away, but in the end, Li Yin only pointed out a general direction. The craftsmanship process is up to the craftsmen under him to study it themselves, and he, the minister, has to reimburse the expenses. How can he not be angry?

"Uncle, you can't say that. My method of pouring steel is the real thing. If they don't have my advice today and let them study it by themselves, it may be difficult to study it even if it takes a hundred years!" Li Yin said very confidently. , In fact, what he said is obviously a bit bragging. Guangang method appeared as early as the end of Han Dynasty, but few people knew about it in Datang.

"Hmph~" Seeing the majestic King Liang playing a rascal in front of him, even if Duan Lun is Li Yin's uncle, he has nothing to do with him. In the end, he can only snort coldly, turn his head to the side, and stop looking at this rascal.

Seeing that Duan Lun seemed to be really angry, Li Yin was also a little worried. He still needs to use Duan Lun in many places in the future, and it would not be worthwhile if the relationship became tense because of such a trivial matter.So Li Yin thought for a while, and suddenly had an idea, and tugged on Duan Lun's sleeve with a flattering expression, making him turn his face away, and then said: "Hey, uncle, it's my nephew's fault this time, how about In this way, I will come out with something new, and this time I promise, I will never fool you with semi-finished products like the steel filling method!"

"Hmph, are you so generous?" Duan Lun still had some doubts about Li Yin's character.

"Of course, and this thing is related to farming. As you know, farming is the most important thing in my Tang Dynasty. Even my father and emperor went to the fields in person. As long as I take out that thing, and then your Ministry of Industry will donate it. If in the future If you promote it, uncle, as the main promoter, you will definitely be famous in the annals of Tang Dynasty." Li Yin started to fool around again, and he had already said the last sentence to the principal and the others just now, without even a single word change.

"Hey, even if your stuff is boasting to the sky this time, I won't believe it unless you show the real thing!" Duan Lun is also a smart person, and he will never fall twice in the same place.

"Isn't it the real thing? Uncle, wait a few days. I'll let the artisans in the house make it when I go back. When it's done, I'll demonstrate it in front of you. Then you will know the benefits of this thing." Li Yan still said with an awesome face.

After returning to the Ministry of Industry, Li Yin bid farewell to Duan Lun and went back to the palace immediately without going anywhere. He was very surprised to see a person, and he heard from the servants that this person had been waiting for him at the mansion for a long time.

"Eighth Brother, why do you have time to come to Sixth Brother's house today?" Li Yin walked into the living room and asked with a smile.The person who came was Li Zhen, who was ranked eighth among the princes. When Li Yin went to elementary school, this kid even grabbed origami paper with Sizi. It can be said that he is a relatively unscrupulous guy.

"Sixth brother, you must help me this time, otherwise I will really have no face to live!" But what people didn't expect was that as soon as Li Zhen saw Li Yin, tears filled her eyes with excitement, as if It was a child without a parent who finally saw his relatives, rushed forward and hugged Li Yin's thigh, crying loudly. ! ! !
