Sheng Chong and Abandoned Concubine: The Sixth Miss Doctor

Chapter 399
Xu Lingyue thought for a while, the world she was in now was different from any dynasty in history known to future generations.

Originally, she thought that the Great Zhou Dynasty should be similar to the Ming Dynasty, but some things were behind the Ming Dynasty, and it seemed to be at the level of the Song Dynasty, but some things were much more advanced than their Song Dynasty.

Therefore, she can't directly confirm the Dazhou she lives in and any dynasty in the memory of agent Xu Lingyue. Dazhou has its own characteristics, which can only be measured by herself.

What she wants to know is basically to ask people to collect data from the people first, and then conduct inductive analysis to get similar data.

Asking this is naturally because she has learned some data before.

What Zhou Qishan said was actually quite satisfactory. After all, he was just talking about a general idea. Different iron ores and different processes lead to different iron yields.

However, at present, Dazhou basically relies on ground furnaces or shaft furnaces to smelt iron ore to obtain sponge iron. If the temperature is higher, liquid iron can be obtained, and by adding some decarburizers, wrought iron can be obtained, and wrought iron Adding reducing agent can become steel at high temperature.

Of course, Dazhou's current smelting level is only carburizing steel, and it doesn't know how to pour steel, so the output of steel is very low, and many farm tools, utensils, and weapons are still pig iron.

Although they can obtain sponge iron through the block smelting method, and then remove impurities by forging, and then obtain steel through tempering and carburizing, and then refine it into steel, they can get steel with good quality.

However, the output of this method is very low. Sometimes it takes several years or even ten years to produce a few good swords. The cycle is too long and it is not suitable for mass production.

This also determines that the weapons at this time are generally not very good. Those good-looking swords and swords are basically collected by honorable generals as personal items, but they cannot be distributed to the army in large quantities.

If there is better steel and weapons can be mass-produced, then the military's weapon rationing will be greatly improved.

Relying on this, she is sure to get the right to operate the iron mine!

"That's true, not only the Shu Kingdom and the Yue Kingdom, I'm afraid those places farther away also rely on the technology of block smelting and tempering forging, which is very inefficient and the output is lower. We have a method of frying steel in Dazhou, not only the output Higher than them, much faster than them, so you can equip the army with better ordnance."

Zhou Qishan looked at her even more surprised: Even the princes and ministers might not be able to explain the smelting of these things, but this Miss Xu actually spoke clearly.

What Xu Lingyue said next surprised him even more.

Xu Lingyue said: "It's a pity that the method of frying steel has many shortcomings. Not only is the environment harsh, but the process is complicated and it is not so easy to master. I'm afraid that even the current imperial craftsman's prison does not have many skilled masters."

Zhou Qishan was shocked and looked at Xu Lingyue in a daze. How could she know so clearly?
Unless it is an important member of the Ministry of Industry, it is impossible for ordinary people to know these secrets.

Even the current crown prince and eldest prince can't speak so brilliantly.

Seeing him stunned, Xu Lingyue decided to scare him again, "Master Zhou, it's not just that, if I'm not wrong, most of the weapons equipped in the barracks are made of low-quality steel produced by the method of frying steel." Right. Those weapons look good at the beginning, sharp and tough, but they are not durable at all. Unless they are forged and turned into [-]-refined steel, it will be much better, both sharp and tough, but the output of such [-]-refined steel is also low, and the The scale of equipment is still unrealistic."
