To be precise, not only do we not use the term "A" and "B" iron materials, but we don't even have corresponding concepts. Of course, there are similar ones, and because the ironmaking technology is very primitive, no matter which blacksmith's shop produces the goods, they are classified into high and low quality.
They are all divided quite clearly.
The most typical and common ones are "wrought iron", "wrought iron", "black iron", and a lot of names such as fine iron.
These are used to identify the quality of steel.
However, these various names have basically disappeared after the advent of blast furnace ironmaking, because this technology can not only continuously produce high-quality "standard steel", but also can produce high-quality "standard steel" continuously.
And the quality, almost without exception, is far superior to ordinary steel, and the most important thing is.
The quality of these standard steels is almost identical and extremely stable, which is why they are known as "standards".
However, this was the initial folk impression, and it was often limited to one city or one place.
Once the scope is widened, the situation will be different. The texture of the standard steel produced by blast furnaces in different places will also be different!
Of course, this is not to say that there is a difference between superior and superior, but that the steel in some places lacks some toughness, and the standard steel produced by blast furnaces in some places is slightly less hardened.
No one noticed these subtle differences at first. After all, even if there are some differences in performance, in general, the steel produced by the blast furnace is still far better than ordinary iron.
But as time goes by.
And with the development of China's steam engines and military weapons, which have higher and stricter requirements for steel performance, experienced and knowledgeable craftsmen gradually discovered that something was wrong.
The steel produced by blast furnaces in different places may not be much different in general, but in the eyes of these truly professional and experienced old craftsmen, the situation can be completely different, and many details will be clearly summarized.
The current terms "A Iron" and "Yi Iron" come from this.
And what Li Sheng is editing recently is exactly related to this.
By the way, the iron materials produced by blast furnaces in different places are different. This is no longer only understood by senior craftsmen, but also by people from all walks of life who have some experience with steel, whether they are ordinary craftsmen or
Young scholars in colleges and businessmen in various places already know the situation here.
Of course, "businessmen and the like" also include Wu Meiniang, who once had the sole power to govern the West Lake Industrial Zone. Therefore, she naturally quickly figured out what Li Sheng was currently doing and was no longer curious.
However, Wu Meiniang is still curious, because in the current situation, although it is true that the quality of iron products produced by blast furnaces in various places varies, it does not seem to require a generation of masters like Li Sheng to study it.
Why did Li Sheng suddenly become interested in ironmaking again?
Wu Meiniang thought for a while, but she felt that she couldn't figure it out. At the same time, she also felt that there seemed to be some mystery here.
Of course, that's what he said, but any changes in the situation seemed to have no impact on Qiongzhou Island, especially the Bilan Manor, so Wu Meiniang just let it go. However, as time went by, among the people in Li Sheng's manor,
The population is getting more and more popular, especially girls.
People from all over the world were chatting non-stop that day, and naturally the conversation came up about Li Sheng - so naturally the topic of ironmaking came up.
but.
Whether it is Wu Meiniang, Wei Ziyu, or other female relatives in Li Sheng's house, when it comes to iron-making, it is just the female relatives who follow Li Sheng. Although they have no worries about food and clothing, they live a leisurely life, but they are boring after all, so they can't help but
I'm thinking of finding something to do so that I won't feel too bored.
But what the female relatives didn't expect was...
After mentioning the iron-making book that Li Sheng recently edited, Li Sheng actually made an earth-shattering motion.
Sell a large number of assets and acquire an iron-making workshop!
To be precise, it is not just an iron-making workshop, it is a large-scale iron-making institution with the largest number of private companies in China. Although blast furnaces are generally used, the scale is small after all, and the technical level is not very good.
It's just that, having said that, although the technical level is not very good and the scale is small, it is still serious about using blast furnaces to make steel. This is still clear.
This is the main steel production force in China. In addition, there are a large number of old-fashioned ordinary blacksmith shops and various large-scale iron smelting plants run by the Tang Dynasty.
There are various forms of them. Although they vary depending on the geographical distance from Chang'an, at this stage of development, they are all highly consistent.
But these.
Because it is obvious that Li Sheng has at least some intention of retiring, Wu Meiniang and others are not very concerned about this.
——So when Li Sheng talked about this, all the female family members were shocked.
Li Sheng's plan is to use almost all the assets under the name of Blue Manor or Li Sheng to acquire a large number of various blacksmith shops, small iron factories, and large iron factories.
Because the "public offering" thing has been running in China for many days, and currently buying and selling an entire workshop, shop, and factory, this kind of thing actually existed in China before there was such a thing as a "public offering"
, and now it is naturally even more widely known.
Naturally, Wu Meiniang and others could not understand Li Sheng's intention, but once they understood it, the sense of surprise in their hearts overflowed on the spot.
What is this for? To suddenly acquire a large number of iron-making shops and iron-making plants.
It was dinner time, and a large number of eyes suddenly gathered at the dinner table to look at Li Sheng, "Sir, why is this?"
By the way, the situation of Li Sheng's group of female relatives is completely different from that of ordinary noble families. This is first of all because the women around Li Sheng are so good-looking.
Secondly, these women who have interacted with Li Sheng from very close to today basically have some backgrounds, and their knowledge is not comparable. It can be said that the level of knowledge of this group of women is no worse than that of most businessmen, or even far away.
Better than.
Therefore, this large group of surprised and suspicious eyes gathered together, which seemed very spectacular. However, Li Sheng's face remained as usual, as if he was unaware of this group of eyes, but in the end he closed his eyes and thought about it, and then opened his eyes again, his face was completely blank.
Firmly, "That's exactly what it is!"
"I have made up my mind, let's take action as soon as possible,"
Li Sheng didn't explain too much, and looked thoughtful from beginning to end, but that was how the matter was decided.
