Chapter 170: Coke and Iron (2)

Walking through the boilers, Xu Qing saw that there were about ten people in each boiler, from burning the fire, carrying water, to beating, each performing its own duties, and casting the weapon in an orderly manner. There are about five boilers in one house, and I saw the supervisor take Xu Qing through more than a dozen houses to a house with "Ordnance Supervisor" written on it. Xu Qing knew that this was where the eunuch's yamen was located.

The supervisor said that there was nothing to entertain in the contempt, so please go directly to the workshop. Xu Qing didn't come to visit the door, so he nodded and agreed. But seeing that the prisoner led Xu Qing to a workshop, there was only one boiler in this room, but there were guards guarding the door. Jian Cheng told Xu Qing that this place is to study how to improve smelting technology and forging technology, Xu Qing said in his heart, isn't this a science and technology park? Fortunately, the equipment in this scientific place is definitely much better than that of production outside.

After the supervisor finished the introduction, he left Xu Qing and the load of coal that Xu Qing brought over. An old man next to the boiler came over and arched his hand: "Old decay Lu Xuan, see Lord Xu." ”

Xu Qingxin said, this old man is arrogant, proud of this self-proclaimed "old decay". Most of the craftsmen in this ordnance prison are ordinary people, and they should be humble when they see Xu Qing. The word "old" was originally a humble title, but because there is a "old" word in it, this humble title has changed its taste. Old man, Oya, although you call yourself a rotten wood, you also call yourself an adult.

However, Xu Qing pretended not to know, but instead respected him: "This old man, presumably his skills are superb, and the official has some new ideas, and he wants to experiment here, I don't know if it's okay?" ”

Lu Xuan smiled: "Well, there is no void under the fame, it is worthy of Lord Xu Qingxu who is crazy outside, and he is good as soon as he speaks." ”

Xu Qing smiled and said, "What is rumored outside is so exaggerated, I'm really ashamed." ”

Lu Xuan shook his head and said: "Lord Xu's saltpeter ice making method, horseshoes, I know, Lord Xu really has a wonderful idea, and the old man also yearns for it, but he only has some experience in making iron here, I don't know that Lord Xu came today, but he came to make iron?" ”

Xu Qing nodded: "I came here today to make iron." I don't know if Mr. Lu is free now? ”

"Since Lord Xu is here, the old man's thoughts are just encountering a problem, so how about listening to Lord Xu's thoughts first?" Lu Xuan said, and the people around him were all in a hurry to prepare for ironmaking.

Xu Qing stopped and said slowly, saying that he didn't want to be in a hurry to make iron, and when they were puzzled, Xu Qing groaned and asked, "Mr. Lu, do you know the four words of pure fire?" ”

Lu Xuan's eyes lit up when he heard this, and then he said: "The furnace is perfect, haha, the old man has heard of it." But the furnace is mixed with green, the old decay has seen it, Lord Xu may not know, we and other iron-smelting people, to refine the green fire in the furnace as the top, a furnace of iron can have five or six traces of green fire, burning half a pillar of incense time, then this iron must be superior......"

Xu Qing asked again: "Mr. Lu, this official has a question, I hope you don't get angry, dare to ask how much green fire you can refine?" ”

Lu Xuan was stunned and said: "No, as long as there is good ore, these ten wisps of green fire are still nine out of ten." ”

"Hahahaha......" Xu Qing suddenly laughed, and Lu Xuan asked puzzled:

"Why is Lord Xu laughing? Isn't this ten traces of green fire enough? Oh, of course, the more the better, but in today's world, the only one who can refine more green fire is probably the old man Yuan Tiangang. ”

Xu Qing said categorically: "Mr. Lu, it's not me Xu Qing who is talking big, wait a while, I'll refine a furnace full of green fire for you!" ”

"What?!"

Lu Xuan looked at Xu Qing as if he had seen his good G friend cheating, but he was so old, he didn't live in vain, looking at the firmness and confidence in Xu Qing's eyes, it shouldn't be a lie. But this full of green fire, that is his life's pursuit, and it is the pursuit of several generations of their Lu family. It's all just a wish, Xu Qing can actually make it now?

If you don't believe it, no matter how powerful you Xu Qing is, I won't believe it today. Lu Xuan looked at Xu Qing's eyes and asked seriously, "Lord Xu, do you say this is your fantasy, or have you already made it and changed it to the cauldron experiment here?" ”

Xu Qing thought for a while and said, "For the time being, I have a fantasy, but I have eighty percent of the experiments. ”

This time, Lu Xuan breathed a sigh of relief, he said in his heart, the old man has been for decades, and it is not false to have a new idea a day, but has the old man succeeded? Is the old man inflated? Is the old man proud? The old man didn't say that he was eighty percent sure.

When Xu Qing saw him like this, he said, "Mr. Lu, you may control the temperature in the furnace?" ”

"The temperature in this furnace is so large that the old man's disciples can do it." Lu Xuan chuckled and said, "However, the old man will personally take care of it for you, and see how your furnace full of green fire is made." ”

Xu Qing didn't say a word, looked around the boiler, and found that there was a vent hole on the boiler, and then shook his head, this coke needs a sealed environment to make it. So he said to Lu Xuan: "Can you block that hole?" ”

As soon as these words came out, everyone present laughed, and Lu Xuan also laughed so much that his white beard trembled, and he looked at Xu Qing and said, "Lord Xu, you blocked that hole, how can this fire burn?" ”

Xu Qing returned solemnly: "Use charcoal, use some red-hot charcoal to pile inside." That hole must be plugged, or it won't be possible today. ”

Then, Xu Qing pulled Old Man Lu Xuan aside and said the general request. Wait until the charcoal in the furnace is burned red, then pour the coals into it, and then cover the lid tightly and the vents to prevent a trace of air from entering. Lu Xuan couldn't resist Xu Qing, and began to think of a way to get up, and after a while, the people in the workshop moved.

Lu Xuan personally commanded, and Xu Qing came up with some ideas on the side, although this was the first time to come like this, but it was only a stick of incense, and the preparations were ready. After the charcoal was arranged, Lu Xuan put some fluffy straw in it and lit a fire. I don't know how Lu Ban knew that the charcoal inside was red, and ordered his men to build a small bridge that had been erected, like a board bridge like a water-carrying movement, and then poured two large barrels of coal into it.

Then someone shut down the big boiler, and someone brought an iron plug to block the vent.

At this time, Xu Qing's heart was beating up, he knew the basic conditions for coal to become coke, eight hundred degrees and a sealed environment, the magazine in the coal, and other organic matter were burned and volatilized, leaving relatively pure carbon that could be burned. However, I don't know if other aspects of the boiler can meet this condition, and the original air in the boiler will also have a great impact. Xu Qing only brought two barrels of coal, and I don't know if I can burn out a barrel of coke.

However, as long as you have coke, steel can be made immediately, so be patient for the sake of steel!
