Zhao Jin knew that the next thing was an argument, but he had his own considerations, so he simply interrupted and interjected: "You just said that it was a pool, and then used bricks and stones to build the bottom and walls, and then put molten iron into it?" ”

Raising this question, Zhu Xingshu, who was sitting at the bottom, was also interested, Xu Housheng gathered his spirits, and replied: "Big brother is right. ”

"Then more than 20 catties of pig iron can only make more than two catties of wrought iron, what is the rest?"

"It's all slag, this pig iron is mixed with a lot of cinder charcoal ash, there is this, the iron mouth is not good, too brittle and easy to rust, only keep stirring and forging, get these slag out, this loss will be big, I thought there would be a good way for the foreigners, after asking Master Zhu, I found that the foreigners are similar to us, and there are a few methods but can only be small-scale steelmaking." Xu Housheng's real outstanding thing is that he knows the craft of coal and iron very well, and he has been interested in it since he was a child, this is amazing, Xu Zhenzhen is a girl, it is inconvenient to go to these places.

"Charcoal ash? Charcoal ash? Zhao Jin really doesn't seem to understand this state, and there are only some fragments in his memory.

"Could it be that the soot was made from the burning of molten iron?" Zhao Jin asked, Xu Housheng was about to open his mouth to refute, but he thought of something, glanced at Zhu Xingshu, and asked: "Master Zhu, I don't know the things in front of the furnace carefully, does Master Jin make sense?" ”

“。 This is not good, some people say that willow wood should not be used for the livelihood of mixing molten iron, that thing is also slag when it is burned, and this brick and stone bottom, these things cannot be burned with molten iron, it should be "Zhu Xingshu said very hesitantly.

Zhao Jin groaned and said: "I have also heard people talk about this method, saying that it is the pool that catches the molten iron, if you use pig iron to make the floor and wall, and then spread the slag from the iron, and then put in the molten iron and fry it, then the slag will be much less, and the amount of wrought iron can be much larger." ”

This is really a very vague memory for Zhao Jin, and there is only one sentence mentioned in the book of the hour record, after he said this, Xu Housheng and Zhu Xingshu looked at each other, but they both had hesitant expressions on their faces, obviously they didn't know whether it was right or wrong, and after a while Xu Housheng said: "Brother-in-law, you can try this method." ”

Zhao Ziying has an advantage over other workshops, that is, dare to try, have the capital to try, even if it is wrong, Zhao Ziying can afford to lose, other workshops are to make money, there is willing to make no precedent attempt, all the improvement and innovation are because of the accumulation of experience and accidental encounters, there is no experiment, in this case, naturally can not compare with Zhao Ziying.

"Xiao Xu, don't worry, these methods of the eldest brother are not not easy to use." Compared with Xu Housheng and Zhu Xingshu, Wang Zhaojing's confidence is very sufficient, because after so many years of getting along, Zhao Jin has come up with too many good ideas.

At this time, Zhao Jin was deep in thought, and the others didn't dare to disturb, and after a while, Zhao Jin said, "Come over the pen and paper." ”

After the family outside brought this in, Zhao Jin took the charcoal strip and drew a rough figure on the paper, like an empty box, with an upward hole at one end, and a downward hole on the other, this empty box is not a complete cuboid, but a curved surface, Zhao Jin circled near the hole below, and said: "Put coal here." ”

Then he drew a circle under the box near the upward hole, and said: "There is pig iron or molten iron here, I remember someone said, it is better to burn coal than to burn coal, you suffocate the coal into charcoal, and then put it in this furnace, the heat of the charcoal fire is upward, and it is always baked in this furnace, and the molten iron over there is always hot, and the blacksmith is holding an iron tong on the side to fish out the wrought iron, which may be better than pouring it directly into the pool." ”

Zhao Jin said while gesturing with his hands, everyone probably understood what Zhao Jin said, it is basically a furnace, the upward hole is the place where the smoke is taken, and the box is the furnace in the shape of winter melon.

Wang Zhaojing and Ruhui listened confusedly, and when they heard the end, Wang Zhaojing couldn't help coughing, and glanced at Zhao Jin, thinking that although the eldest brother had a lot of good ideas, he was timid in this, although Wang Zhaojing himself didn't know how to make iron, but he also knew that ironmaking should use charcoal fire to burn the ore into molten iron, and the fire and iron had to be close together.

But as soon as he finished signaling, Wang Zhaojing found that something was wrong, he found that Xu Housheng and Zhu Xingshu's expressions were shocked, looking at Zhao Jin's eyes as if he was looking at a ghost, Zhu Xingshu didn't care about any etiquette, first looked at the sketch drawn by Zhao Jin, the lines were very sloppy, there was no explanation just now, and I really couldn't understand what it was.

"This way, this way." Zhu Xingshu muttered there, but there was no complete word, Xu Housheng had no etiquette to speak of, the whole person was lying on the sketch, ignoring a few people around him, and pondered for a while before he looked up and said: "Brother-in-law, how did you come up with this method, I heard the masters say that there is a similar method in Shanxi Tieshenggou in the past, but I can't try it, brother-in-law, you have this method clearly, you know how to put iron, how to burn the fire, yes, yes, you have to use charcoal, use coal coke, The fire that burns is steady, and the coal fire and the wood fire are hot. ”

Zhao Jin coughed a few times at this time, and after a pause, he replied: "It's too fine, I don't know, it's this method that my second uncle saw when he went to the university, and he told me when he came back, how to use it specifically, and you have to think about it, what I said may not be right." ”

"It's good to have this method, this method will open up all things, nothing more than that this furnace should be heat-resistant, the clay bricks of the porcelain kiln can be built, there must be a good master here in Xuzhou, stirring the molten iron with a wrought iron rod, the top is covered with a wooden block, the person who uses it puts on leather gloves, and then changes it when it burns out, but there is a difficulty, you say that this has to look at the fire, this fire and molten iron hurt the eyes, and you will be blind if you stare at it for a few years, and those who can touch the fire and know how to see the color are all masters, It's a shame that it's so costly. Zhu Xingshu was already excited, and there was nothing rude or rude, just thinking about what to say over there.

Xu Housheng was also very excited at this time, and when he heard Zhu Xingshu's words, he smiled and said: "Master Zhu, don't worry about this, our Xu family has its own method, do you know that Mojing is eye-catching?" ”

Over there, Zhu Xingshu patted his head, and suddenly said, "Is your Xu family using this to see the fire?" No wonder, no wonder, your Jingshan Xu family is known as the first coal and iron in the world, and there is such a method. ”

The two of them were talking about it as if no one was around, Wang Zhaojing and Ruhui watched dumbfoundedly next to them, Zhao Jin listened with a smile, he liked this kind of scene where craftsmen and technicians argued about the details, such a scene always made him feel very pleasant, this ink crystal glance sounded like a very high and unfathomable thing, but everyone here knew what it was, it was nothing more than black crystal polished into a disc and inlaid on the copper wire, to put it bluntly, it was a kind of glasses, at this time it was called eye skimming, it was one of the tools for nourishing the eyes, and there were many people in Jiangnan.

This kind of appliance is the most suitable for observing bright molten iron and fire, and the damage to the glasses is also very small, the quality of the iron tools on the Xu family's side is outstanding, I didn't expect that there is such a reason, and it can be used at this time.

Many inventions and innovations are like this, not necessarily what is a brilliant idea, maybe a lot of things have long been mastered, but few people to find another way, think in a different direction, or stick to the so-called ancestral law, feel that the past is right, and the demand of this era is not so big, there are several places in the world where iron and iron are made, can already supply all the demand, even oversupply, naturally there is no need to think about any improvement, if the demand is huge, Someone will inevitably come up with new ways to improve productivity.

After Zhao Jin said this opinion, Xu Housheng and Zhu Xingshu were shocked, but there was nothing they didn't understand, they could figure out this set of things, they just didn't think of it, and the tool matching behind it was something that Zhao Jin never thought of.

"Jin Ye, this method must be kept, if you let others steal it, it will be a big trouble, relying on this method, the Xu family can eat for a hundred years, Jin Ye, you must use capital crime to deter!" Zhu Xingshu had already thought of this aspect, he could only say that he was extremely excited at this time, and he didn't consider that if he wanted to kill people and keep it secret, the most important thing to kill was him, a new outsider.

Wang Zhaojing shook his head and smiled, nodded and said, "Master Zhu, don't worry, we will arrange this matter." ”

Ruhui also had an excited look on his face, as the head of the Agricultural Reclamation Department, there was a great demand for iron and even weapons in the Grange below and related places, if Zhao Jin's method could produce wrought iron on a large scale, it would also be of great benefit to his side.

Over there, Wang Zhaojing turned sideways with a smile and said, "Big brother is really capable of anything, and he actually knows such skills." ”

"It was the second uncle who told me, and the second uncle traveled south and north to see a lot of knowledge, and I recorded everything he said in the book." Zhao Jin replied with a smile, whether others believe it or not, now it is the credit of the second uncle Zhao Zhenxing, and it is easy to explain it.

"Second Uncle is really well-intentioned." Wang Zhaojing sighed, and his expression couldn't see anything, it seemed to be wholehearted admiration.
