Zhao Xing's iron factory, after obtaining Zongzheng's approval and obtaining the right to produce, was very large when it was built, and he had to be in place at one time.

In this plant, there are not only smelting ovens, but also a coke plant.

Yes, it's a coke plant.

The temperature of coke is more than ten times that of coal, and such fuel will greatly increase the furnace temperature, and the pig iron will be directly smelted into wrought iron, and then the pig iron wrought iron will be stacked and carburized, and the tempered blast furnace can be used to directly train steel. Although limited by the process and the output is very small, this is enough for Zong Zheng to look at Zhao Xing as a celestial again.

"I don't dare to be praised by Zongzheng, I'm just a half-little understanding, detailed, or need to be constantly explored and discussed by latecomers."

Zhao Xing is actually not even half-baked about steelmaking, because the technology he learned was obtained from watching and traveling.

Fortunately, the authors of the crossing were still very responsible, and they did not make up nonsense, so that Zhao Xing smelted coke and steel after several tests.

Originally, Zhao Xing also wanted to make cement and glass in large quantities in accordance with the rules of crossing, but after detailed demonstration and investigation, Zhao Xing found that in fact, in order to make cement in this era, it is far more difficult than steel.

As far as the reason is concerned, steelmaking, with its own half-baked but technology, in the basis of smelting in this era, can still be realized, in fact, their own later generations to the soil method of steelmaking, but the ancient period of technology, greatly improved.

As for making cement and glass, Zhao Xing was completely depressed when he thought of their production process. Because, in this day and age, there is no basis for the production of such a thing, and it is really self-made.

In fact, the raw materials of glass are very common and simple, but the production process is definitely not as simple as those who travel through imagined, it is a huge system engineering. Otherwise, for thousands of years, the so-called glass burned out can only be called glass, which is not transparent at all.

Firing glass requires a kiln, a brick kiln that can withstand thousands of degrees of high temperature, which is not something that ordinary red bricks can withstand, and it needs refractory bricks.

Well, then you have to make refractory bricks first. However, refractory bricks can not be burned out of ordinary loess, that needs refractory soil, okay, then find refractory soil first, but this thing seems to be only available in Northeast Liaoxi, but that place is now the territory of Yan Guodu, and now Zhao and Yan are mortal enemies, and it is definitely a dangerous place to invest and build a factory there.

Well, even if the refractory soil is available, start firing refractory bricks, etc., and make refractory kilns, you have to refractory cement to build this thing, and the refractory cement material is available in this county, in Shanxi, and Hebei, but how does refractory cement come from?

Then you have to open a mine, build a cement plant, and build a cement plant to have machinery and equipment, those people who pass through the use of ancient manual methods can process raw materials, that is unsubstantiated obscenity, you use a stone mill to grind out a ton of mineral powder I see? If you don't do it, you're old and weird.

Since you want a machine, well, then you need good steel, yes, let's make steel again, now we have smelted it, and there is no shortage of coal, but now I use the earthen kiln of the big steel to make steel, in fact, it can only be regarded as crude steel, and the cold weapon is qualified.

In the absence of a little foundation, a traverser who is not even a half-baked person wants to complete such a big project, which is tantamount to the reader asking this traverser to conquer the entire earth and the universe with a burning stick.

Zong Zheng looked at such a large scale and couldn't help but worry about Zhao Xing: "If you go all out, the iron produced will be unsalable." ”

Zhao Xing's production volume is actually not large, and there is no annual output of 100,000 tons from a small smelter in later generations.

At best, Zhao Xing's smelter produces less than ten tons a day. This is still limited technology and technology, and it is limited from the mine, which is also helpless.

But even so, everyone was already worried about his sales after dropping their jaws in surprise.

Yes, even such a small amount of production will produce unsalable.

Because, because of this era, iron is called evil gold, because of his original shortcomings, so that even if it is a farm tool, it is better to use precious bronze, or simply wood, than to use iron. That's why Zongzheng is worried about this child he likes.

Retracting his off-topic thinking, Zhao Xing smiled and confidently answered Zongzheng's concern: "Actually, iron replaces bronze, which has his huge advantages, but it is just that everyone did not develop iron and its advantages in the first place. ”

Zong Zheng was noncommittal, while inspecting and watching, he listened to what Zhao Xing said.

"For example, the army, because the iron is easy to break and easy to rust and becomes not sharp, so everyone abandons it, so I provide you with a steel ring hand knife, use his thickness to offset his easy breakage, and use precious steel as a blade to offset the shortcomings of rust, so that the advantage of our iron sword in length is recognized by the army."

Zong Zheng admitted that Zhao Xing was right.

"And the armor of the soldiers, the accessories on the horses because of rust and rot, and they are not used, then, for example, the molten iron I am smelting now, I smelt the iron I smelt again, and then add a little tin and chromium to it, so that the iron will not rot for a long, long time." Then he looked at Zong Zheng and explained: "The iron punishment tripod cast by your ancestor Zhao Ying is actually a kind of gold made by mixing an appropriate amount of other metals, so that for more than 200 years now, it has experienced countless winds and rains in the square, but there is still no rust, which is the proof of this." ”

Zong Zheng suddenly said: "The emotional ancestors have this method, but unfortunately there is no inheritance." ”

Zhao Xing smiled, in fact, it was not a deliberate smelting of gold, but a coincidence of a blind cat and a dead mouse.

Then he pointed to the red blast furnace: "Although the smelting cost of this kind of iron, which I call Hejin, is higher than that of ordinary iron, it will still be far lower than the cost of bronze, but it is more durable and wear-resistant, and it also overcomes their original shortcomings, and of course it will be accepted by the people." Then he took Zongzheng to the front of the casting molds, where the shovels and ploughshares for agricultural use were being made by pouring the molds, yes, the shovels and ploughshares of later generations, not the open plows and ploughshares of the present generation.

Zong Zheng understood at a glance that this new tool was much more advanced than the bronze one, and the efficiency would be greatly improved: "Is this also invented by Zhao Xing?" ”

Zhao Xing smiled proudly: "I am based on agriculture, and I should make every effort to improve production efficiency, so I have the invention of these things." ”

Zong Zheng officially gave Zhao Xing a solemn salute: "Your merit is only lower than that of Shennong for the whole world." ”

Zhao Xing hurriedly avoided modesty: "Everything is for the people of the world to produce more food and fill their stomachs, which is also the responsibility of our superiors." ”

Zong Zheng thinks so.

"I invented this farm tool, it will definitely be accepted and promoted by everyone, the vast world has a lot to do, as long as the largest market is opened, do we still hate this little bit of output? We should be worried that our production is not high. ”

Zong Zheng hurriedly said goodbye and went back to arrange how to increase production.

Due to Zhao Xing's vigorous implementation and drive, Dai County has become the factory area of the Central Plains, and all kinds of industrial products began to go to other vassal states here, while bringing a steady stream of wealth to Zhao Xing and Dai County, industry and capitalism sprouted, more than a thousand years in advance, and began to sprout, and at this time, Zhao Xing can be regarded as the largest capitalist in the Warring States Period.
