The stove I just talked about is a reverberatory furnace, Zhao Jin flipped through the records of his childhood, and often saw this, but he didn't have any deep memories, if it wasn't for the in-depth conversation with the knowledgeable Xu Housheng and Zhu Xingshu today, I'm afraid I wouldn't be able to remember this point.

At that time, the main reading was mainly military things, the reason why this reverberatory furnace was mentioned, it was said that because of the many wars in Europe, the demand for weapons and armor increased, especially the demand for firearms made of wrought iron increased greatly, in order to meet this demand, Western and Central European countries began to improve the smelting and casting technology, this reverberatory furnace is one of them, because it reduces the contact between molten iron and charcoal, and at the same time maintains high temperature in the production process, so in the process of converting pig iron into wrought iron, the loss is reduced. Dramatically increased production, one of the examples of the so-called war driving technological development.

Zhao Jin is not sure whether this technology is now appearing, just now Xu Housheng mentioned the place name "Tieshenggou", the Xu family because of the wealth and power, so has been carefully collecting the world's coal and iron skills, and sorted out into a book to pass on, even if Xu Housheng has not been out of anything, he can also be well-informed by this, why is such a good method not promoted, but it is normal to think about it, this kind of secret method must be passed on from father to son, and it is not good that daughters-in-law and daughters can not pass it on, so it is naturally not widely spread, but according to Zhu Xingshu's words, What refining method is used by white people now, and the refining method of Daming is the same meaning.

"This hydraulic machinery has been used a lot in Europe, not only to save manpower, but also to process larger objects, in terms of craftsmanship, we are too far behind." Zhao Jin said with emotion.

Regarding Zhao Jin's feelings, Wang Zhaojing and Ruhui both nodded in agreement, but their faces still accidentally showed a disapproving look, in their opinion, what is backward, but some clever methods Da Ming himself did not think, and now this is not to catch up?

Xu Housheng and Zhu Xingshu didn't even continue to chat, they hurriedly left the past to prepare, and Wang Zhaojing was also busy, if this method is really as important as everyone said, then it must be kept secret, and even the people involved must be kept close, and there can be no omission.

For this newly built iron furnace, a large courtyard was specially arranged, the fence was raised, the security was tight, and the craftsmen who built the iron furnace were the most reliable people of the Xu family, and after doing this work, they were placed under house arrest in a disguised firearms workshop.

However, all the masters of the Xu family who participated in the construction of this furnace know a little bit about the business of burning coal and making iron, so they naturally know the meaning of this iron furnace, and they can also understand why they are under house arrest.

Wang Zhaojing and Ruhui naturally saw the excitement of Xu Housheng and Zhu Xingshu, as well as Yu Shan, Louis, those craftsmen who were born in the Ming Dynasty and came from abroad, but in their opinion, this is just a trivial matter, Zhao Jin is now in charge of the overall situation, and he should put his mind on bigger affairs, and even have the world in mind.

But what surprised them was that Zhao Jin's attention to the craftsman hall was not only the blacksmith, the main force of the firearms workshop was the blacksmith and apprentice helpers, but the firearms, armor and various utensils also needed a lot of wood and other materials, so there were many carpenters and other craftsmen in the Zhao Ziying craftsman hall.

Zhao Jin paid attention to the blacksmith's side for a long time, and then turned his attention to the carpenter's side.

"Big brother, the Emperor of the Apocalypse is addicted to carpenter things all day long and ignores government affairs, but as a result, the government is controlled by Wei Zhongxian and others, and the Donglin Party is constantly attacking, and the world is in chaos, this is a lesson from the past, big brother must be vigilant." Wang Zhaojing was worried about Zhao Jin's approach, and his remarks could be said to be very serious.

"He doesn't care about things, others take care of him very well, don't worry, I know what you mean, I have my reasons for doing this, you think the art of craftsmanship is a small way, but I think this is one of the foundations, and the cultivation on our grange, do this well, our family can win all battles." Zhao Jin explained with a smile, but Wang Zhaojing had a cold face, and directly made it clear that if Zhao Jin continued like this, he would invite Zhao Zhentang and Wang Youshan and other elders to come over.

Zhao Jin was also a little crying and laughing at such a straightforward advice, but he still had to show that all his business was not delayed, and Zhao Ziying was also operating as usual.

"The eldest brother is well-informed, he must have heard the allusion of the king of the ivory chopsticks!" Wang Zhaojing said more heavily.

These words made Zhao Jin very annoyed, but he was helpless, he just said: "These things have nothing to do with fun, I have to finish it, now you may not know why I am so concerned, a year later, two years later, you will understand, we brothers for so many years, don't you know what kind of person I am?" ”

Zhao Jin never thought that the conversation between the brothers could reach such an embarrassing point, so he almost swore an oath, Wang Zhaojing still refused to relax, and finally he was a little helpless, just said: "What kind of person is the eldest brother, the younger brother knows very well, but the younger brother also feels that the eldest brother is too stable, and the enterprising mind is a little worse, this stability is not a bad thing, but in such a rich and noble situation, it is easy to slack off, the eldest brother should not forget, we are now walking on the edge of the cliff, and if we are not careful, we will be crushed!" ”

"You watch, you watch." Zhao Jin explained that in the end, he was also a little angry.

Advice is advice, Zhao Jin's schedule is still decided by himself, Wang Zhaojing followed with a cold face, and everyone was not very comfortable.

Compared with the busy blacksmiths in the firearms workshop, the carpenters in the workshop are also very busy, and the handles, handles, grips and wooden parts of various utensils, such as firearms, spears, knives and axes, and the wooden parts on various utensils, all need to be produced by them, because there are a large number of blacksmiths on the side of the Xu family in Jingshan, Zhao Ziying has always screened out craftsmen and apprentices to supplement the homeless, and the carpenter, in addition to the craftsmen in the prisoners of the homeless, Yunshan Xing went as far as Shanxi and Huguang to recruit, as long as it is a carpenter with craftsmanship, they will all settle down and pay well, Moreover, apprentices who learned carpenter's work were encouraged, and there were also such and such preferential treatments for these apprentices, and in this way, they barely maintained a sufficient carpenter force.

The carpenters of Zhao Ziying now have a new job, that is, to make equipment for spinning and weaving, Songjiang Yu has already sent a model, various equipment for pressing cotton, spinning, and weaving, and the carpenters should make according to this, and the cotton planting in various granges in Zhao Ziying has begun on a small scale, and it will be rolled out on a large scale in the coming year, and these instruments are also necessary.

In addition to the style, Zhao Ziying also invited craftsmen who were familiar with spinning and weaving from Songjiang and the homeless people, and asked them to make equipment with the carpenters, and felt very uncomfortable with the carpenters, and said that those instruments were very simple, and everyone made them seriously, so there would be no leaks, why let these people who don't know how to work as carpenters star, isn't this looking down on people?

Zhao Jin knew these complaints, but these spinning and weaving equipment were for those weavers, so he naturally had to listen to their opinions, so that they could be used well.

After Zhao came in, the carpenter's workshop was full of spirits, and they wanted to show themselves well in front of their benefactors, and a few people with good eyes even deliberately displayed the things they made skillfully around them, but they didn't expect that Wang Zhaojing's face would turn black after seeing these things.

To everyone's surprise, Zhao Jin stayed in the place where the spinning wheel was made for the longest time, and made a lot of very childish actions, such as the spinning wheel was rotating vertically, but Zhao Jin kept pushing him down and flattening, which made people very confused, and he didn't know what the intention was at all.

“。 This spinning wheel can only bring one spindle, you think about it, if it is knocked down and flattened, can a spinning wheel drive several more spindles, you don't have to worry about the labor and materials, it doesn't matter if you can't do it, but as long as you can figure it out, there will be a heavy reward on my side, and the children will also be treated well, and I Zhao Jin is a good talk."

Zhao Jin gave this promise, the carpenters were naturally eager to try, in fact, after the spinning wheel was put down, Zhao Jin put forward a request, and many people were already able to figure out how to do it, and the next thing was nothing more than to study with those weavers, how to make this thing suitable for use, and then win this lottery.

“。 I don't want KitKat fun things, I can make things that save effort and make things faster, how much you want, there will be a heavy reward, you can ask, how much do blacksmiths get because of innovation" Before leaving, Zhao Jin made a commitment to these carpenters and also put forward needs.

What made Wang Zhaojing breathe a sigh of relief was that after Zhao Jin did this, he told Xu Housheng to report the progress in time, and then he didn't go over there much, Wang Zhaojing understood a little that Zhao Jin had been in the past for these purposes from the beginning, and now that it has been completed, naturally there is no need to waste time there.

The flag awarding review of the second brigade and the flag awarding review of the third brigade have to be visited by Zhao Jin in person, which is fine in Huai'an North District, but the flag awarding and proofreading of the third brigade is different, the third brigade itself is nothing, but the Qingjiangpu local area is a sensation, Zhao Jin came to Qingjiangpu again, and those who want to communicate and flatter must hurry, and even people from Yangzhou have rushed over.

Originally, the martial arts competition held in Xuzhou will be held in Qingjiangpu, jointly organized by Yunshanxing and Qingjiangpu Chamber of Commerce, and the proceeds will be shared proportionally.

The martial arts competition of those people at the martial arts conference is very exciting, but the Qingjiangpu businessmen are not concerned about this, they can keenly see the various business opportunities brought by the competition, the business of inns, restaurants and courtyards will be hot, and there will be businessmen from other places to come here, everyone trades, all aspects are benefits, which will make this Qingjiangpu more prosperous.

Historically, reverberatory furnaces appeared at a much later time, but the technologies required for the construction and operation of reverberatory furnaces were completely achievable in this era, and the difference was nothing more than an idea
