An He took in the other party's reaction, but he didn't break it, but pointed to the blast furnace with a smile and said. Pen, fun, and www.biquge.info

Hearing An He's words, Master Jiao was stunned for a moment, and then smiled:

"If you are interested, it is an honor for the lower officials!"

As soon as he approached, An He felt a wave of heat coming to his face, and then looked at the smoke billowing above the blast furnace, and it seemed that the furnace inside was burning.

"Zhonglang General, this is the blast furnace for iron smelting, we will superimpose the fuel and iron ore and limestone layer by layer, ignite the fuel inside, and then blow the air from the bottom with a blower, when it reaches a certain furnace temperature, the iron in the ore is heated into molten iron, which flows out from below, which is very common pig iron. Now it is making iron with the coke that has just been delivered, and the coke is growing new fuel, so what we need to do now is to find out its character and facilitate large-scale application in the future. ”

The coke director didn't know that the coke was made by Anhe in front of him, so he introduced the coke in such detail.

"Hehe, Master Jiao, you may not know that this coke is the masterpiece of General Zhonglang."

Hearing Master Jiao's words, Duan Lun said with a smile.

"Oh?"

Master Jiao glanced at An He with some hesitation, he had also heard of An He's name, and knew that this young man was good at making tools, but iron-making was different from others, this was all real experience, not that it could be done if he was smart, but looking at An He's age, it was impossible to have any experience in iron-making, so when he heard An He come to guide them in iron-making just now, he would be so disdainful.

"Zhonglang will be talented, and the little old man doesn't know that the coke is made by Zhonglang General, but it makes you laugh."

Jiao said with a bow, as a craftsman who has been smelting iron all his life, of course he knows the importance of coke for ironmaking, this coke has good air permeability, and can support a large amount of iron ore stacking, the most important thing is that using coke to make iron can increase the furnace temperature, so that the iron quality is better, the amount of iron produced is also higher, and it is not like charcoal, which will make the iron too brittle, which can be said to be the best fuel he has seen in his life.

"Hehe, it's okay!"

An He saw that this Jiao was in charge of the matter, and his attitude towards himself immediately became more respectful, and he was quite proud in his heart, the other party's respect just now was only because of his identity, and the current respect was the respect for his own talents, and the meaning of these two kinds of respect was completely different.

"Master Jiao, these should be used for wind blowing, right?"

An He stretched out his hand and pointed to the row of skins next to the blast furnace, which were stretching and shrinking in a reciprocating motion, the gas outlet was connected to the bottom of the blast furnace with an iron pipe, and the horses were powering the skins.

"Qi Yu Zhonglang General, this thing is called water drain, it is indeed used for blasting, because it is generally driven by water power, so it is called water drain, but because the blast furnace here is only for experiments, and it does not really produce iron, it is not used much, and there is no water source around, so it is driven by horsepower, so it can be called a horse row."

Director Jiao stepped forward and introduced.

"Oh~, I have a question I want to ask Master Jiao, when making iron, is the higher the temperature in the furnace, the better?"

An He said with a smile, although there are not many places he can improve in this blast furnace ironmaking, but there happens to be one in front of him, and with this improvement, he can also shock the craftsmen of Jiao Gongzhi and let them know their talents, so that they can better command them in the future steelmaking.

"Uh~"

Jiao was stunned for a moment, he was still not used to Anhe's jumping thinking, and he asked about the water drain just now, why did he run to the furnace temperature all of a sudden? But after all, he has been doing iron smelting all his life, so he opens his mouth to these questions.

"Qi Yu Zhonglang General, if you don't consider the degree of burning resistance and cost of the furnace, the higher the furnace temperature, the better, such as the coke that Zhonglang will make you, one of its biggest advantages is that the temperature is higher than that of charcoal, and it is also more resistant to burning."

After An He heard the other party's answer, he laughed and said:

"Master Jiao, since you know that the higher the temperature, the better, but why do you still blow cold air inside, isn't this like pouring cold water into a pot of boiling water, how can it be possible to make the furnace temperature inside reach the highest?"

、

There is a saying that 'a word wakes up the person in the dream', An He's words that seemed to be joking listened to the ears of Jiao Zhushi, but it was like a thunderbolt, which blasted a gap in his already fixed thinking, coupled with An He's analogy is very vivid, so he grabbed the key at once, and said excitedly:

"General Zhonglang, you mean that you can heat this air and blow it into the furnace?"

"Hehe, Master Jiao is really experienced, and he has grasped the key point at once!"

An He praised that air preheating is actually a layer of window paper, and everyone understands the truth, but no one has ever thought of doing this, mainly because the experience of predecessors limits their thinking.

An He stepped forward and walked to the side of the water row, stretched out his hand and gestured on the ground:

"Duan Shangshu and Jiao, please see, you can build a preheating room here, heat the air and blow it into the furnace, so that the temperature in the furnace will not be reduced due to cold air, and the higher the furnace temperature, the iron in the iron ore can also be smelted as soon as possible, which not only saves time, but also the quality of the iron smelting is much stronger than before."

Duan Lun, as the secretary of the Ministry of Industry, still knows some about the art of iron smelting, so he can also understand Anhe's words, but as an official who coordinates the overall situation, he heard an inappropriate thing from Anhe's words, and asked at the moment:

"General Zhonglang, I understand what you said about this preheating chamber, but have you thought about it, this preheating chamber also consumes fuel, although the quality of smelting iron is good, but the cost has also increased, will this be a little cost-effective?"

Hearing Duan Lun's question, Master Jiao, who was excited, preemptively said:

"Lord Shangshu, adding a preheating chamber will not increase the cost, because after the furnace temperature is raised, the smelting time will be shortened, so that the amount of fuel can be reduced during smelting, and the saved fuel can just be used to heat the air."

"Huh~, wonderful! This was my negligence! ”

Duan Lun heard Jiao's explanation. At the moment, his eyes lit up, and at the same time, he admired Anhe's talent even more, and he made a small change to the blast furnace after a while, which suddenly made the quality of the blast furnace iron-making rise, and it could also speed up the furnace iron-making time. Don't underestimate this little improvement, Datang has countless iron-making furnaces, if each furnace is changed according to what An He said, then not only will the annual iron output increase a lot. And the quality of iron can also be raised to a higher level, which is a great feat!

"General Zhonglang, everyone says that you have the guidance of a god, but I didn't believe it yet. When I saw it today, I realized that those rumors are simply not exaggerated to you! ”

Duan Lun thought that he had achieved such a great political achievement out of thin air, and under the excitement in his heart, he couldn't care about any manners anymore, so he stepped forward and patted An He's shoulder and praised loudly.

"Where is it, Duan Shangshu, you are too complimentary!"

An He hurriedly said modestly, but he couldn't hide the pride on his face, especially when he saw that Jiao Shishi's eyes were shining with admiration for him, as if he had seen a pile of gold and silver treasures. I can't wait to snatch it and hold it in my arms and kiss the two. (To be continued.) )
