After Zhao Xing's iron factory was approved by Zong Zheng and obtained the production rights, it was very large during construction, and he had to be in place at one time.

In this factory area, not only is there a smelting oven, but also a coke factory.

Yes, it's a coke factory.

The temperature of coke is more than ten times that of coal. Such fuel will greatly increase the furnace temperature, directly smelting the pig iron into the iron, and then using the pig iron stacking carburizing method, you can use the tempering blast furnace to directly train the steel. Although due to the limited process and the output is very small, this is enough to make Zong Zheng look at Zhao Xing again.

"I dare not be praised by Zong Zheng. I am just a little bitch and a little bit. It is detailed, and it still requires latecomers to constantly explore and discuss."

Zhao Xing actually didn't even count as half-baked when it comes to steelmaking, because the skills he learned were obtained by reading time-travel novels.

Fortunately, the authors of the time travel novel are still very responsible and do not make up randomly. After several experiments, Zhao Xing refined coke and steel.

Originally, Zhao Xing wanted to make a large amount of cement and glass according to the rules of time travel, but after detailed argumentation and investigation, Zhao Xing found that in fact, if he wanted to make cement in this era, it would be far more difficult than steel.

For the reason, it is still possible to refine steel with my own half-baked but skilled technology, which has the foundation of smelting in this era. In fact, my later generations summarized into the local steelmaking process, which is just a great improvement in the technology of this period in ancient times.

When making cement and glass, Zhao Xing was completely frustrated when he thought of their production process. Because in this era, there was no foundation for producing such things, so it was really starting from scratch.

In fact, the raw materials of glass are very common and simple, but the production process is definitely not as simple as those time travelers imagine. It is a huge systematic project. Otherwise, the so-called glass burned by humans for thousands of years can only be called glazed glass, which is not transparent at all.

The firing of glass requires a kiln, and a brick kiln that can withstand high temperatures of thousands of degrees. That is not something ordinary red bricks can withstand, but it requires refractory bricks.

Okay, you have to make refractory bricks first. However, refractory bricks cannot be burned with ordinary loess, so they need refractory soil. Okay, then find refractory soil first. But this thing seems to be only available in Northeast China and Liaoxi. However, that place is now the capital territory of Yan State. Now Zhao State and Yan State are mortal enemies. Going there to invest and build a factory by yourself is definitely a dangerous place where you can no longer be dangerous.

Well, even if you have refractory earth, you will start firing refractory bricks, etc., and you will also have to make refractory kilns. You have to have refractory cement to build this thing. Refractory cement is available in this country, just in Shanxi and Hebei. However, how do you get refractory cement?

Then you have to start a mining and build a cement factory. When building a cement factory, you have to have mechanical equipment. What people traveling through time say can process raw materials by using ancient manual methods, that is, without any evidence. If you use a stone mill to grind a ton of ore powder, I will see? It would be strange if you don’t live forever.

Since you need a machine, okay, you need good steel. Let’s build steel again. Now we have made it ourselves and there is no shortage of coal. But now we use the earth kiln that practices steel to make steel, which can only be considered crude steel. We can build cold weapons with the qualifications. We can make the machine with it. After thinking about it, we can wash and go to bed.

Without a little foundation, a time traveler who is not even a half-baked person wants to complete such a large project is tantamount to a reader asking this time traveler to conquer the entire earth and the universe with a fire stick.

Seeing such a large scale, Zong Zheng couldn't help but worry about Zhao Xing: "If you start with all your strength, the iron produced will be unsold."

Zhao Xing's production volume is actually not large, and it is not as high as a small smelter in later generations that produces an annual output of 100,000 tons.

At best, the daily output of Zhaoxing's smelter is less than ten tons. This is still limited by technology and technology, and it is limited by mines, which is helpless.

But even so, everyone was surprised to drop their chin and worried about sales for him.

Yes, even such a little production will lead to unsalable sales.

Because, because of this era, iron was called evil gold, and because of its original shortcomings, even if it was agricultural tools, Ning Yuan would use precious bronze with better plasticity, or simply wood, and would rather use iron. Therefore, Zong Zheng was worried about the child he liked.

Retracting the off-topic idea, Zhao Xing smiled and answered Zong Zheng's concern with confidence: "In fact, iron has his huge advantages in replacing bronze, but it was because everyone had not developed iron and his advantages and uses."

Zong Zheng did not comment, but while examining and watching, he listened to what Zhao Xing said.

"For example, in the army, because the iron is easy to fold and rust and becomes unsharp, we will abandon it. Then I have provided you with a steel ring hand knife, which uses its thickness to offset its easy to fold, and uses precious steel as a blade to offset the shortcomings of rust. In this way, the advantage of our iron sword and iron sword in length has been recognized by the army."

Zong Zheng admitted that Zhao Xing was right.

"And the soldiers' armor and accessories on the carriage are rotten because of rust and rotting. Then, for example, the furnace of iron I am smelting is the iron I smelted again, and then add a little tin and chromium into it. In this way, the iron will not rot for a long time." Then he looked at Zong Zheng and explained: "The iron punishment cauldron cast by his ancestor Zhao Yang is actually a kind of gold made of mixed with an appropriate amount of other metals. Therefore, for more than 200 years, I have experienced countless winds and rains in the square, but there is still no rust. This is a proof."

Zong Zheng suddenly realized: "The ancestors of love have this method, but unfortunately there is no inheritance."

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

Then he pointed to the red blast furnace: "Although this kind of iron, which I call Hejin, has a higher smelting cost than ordinary iron, it will still be much lower than the cost of bronze, but it is stronger, durable and wear-resistant. It also overcomes their original shortcomings and will of course be accepted by the people." Then he took Zong Zheng to the casting molds, where the molds were being reversed to produce agricultural shovels and plowshares. Yes, the shovels and plowshares and plowshares from later generations, rather than the opening plows and hoes of the present.

Zong Zheng understood at a glance that this new tool is much more advanced than the bronze hoe, and its efficiency will be greatly improved: "Is this also invented by Zhao Xing?"

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

Zong Zheng officially gave Zhao Xing solemnly: "Your credit is only lower than Shennong for the whole world."

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

Zong Zheng deeply agrees.

"I invented this agricultural tool and will definitely be accepted and promoted by everyone. The vast world will do great things. As long as the vast majority of markets are opened, will we still hate this little output? We should worry about the low output."

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