Ganqing Palace.

Zhu Youxiao looked at Sun Yuanhua's eagerness and couldn't help but caress his forehead and pretended to think.

The emperor is so smart. Many problems of technology manufacturing can be solved. For example, crucible steelmaking, coke iron smelting, and the addition of limestone to steelmaking...

This is the feeling that Xu Guangqi, Sun Yuanhua and others gradually developed. Even if they find it strange, they dare not ask in detail. They can only explain it with their natural wisdom.

In fact, this is what the young emperor learned from the vast number of online knowledge in his previous life, and many of them were only a little bit of aware of it.

But this little understanding often makes it look like a flash of inspiration for the technical problems that trouble Xu Guangqi, Sun Yuanhua and others.

Crucible steelmaking was successful because its technology itself is not complicated, and the core is the production of clay crucibles. It is not difficult to solve the problem by using different ratios.

It is only a matter of time before steel with high hardness can be refined, and then the carbon ratio can be adjusted to create steel sheets with strong elasticity.

In other words, the creation of flintlock rifles has shown light.

However, the difficulty raised by Sun Yuanhua is the speed and efficiency of crucible steelmaking, which means that he wants to greatly shorten the current time for melting iron from three hours.

Zhu Youxiao went to see the production of the capital steel mill. He thought that the output was low and he would build more crucibles. However, this lazy mind was defeated by Sun Yuanhua's responsibility and good learning.

"This, I think--" Zhu Youxiao finally found a solution from his previous life's visit and said slowly: "The blowing is to make the coke better burn and heat it, but the air conditioner blown in is not good."

Sun Yuanhua blinked his eyes, feeling that he had some ideas, and asked tentatively: "Long live means heating the air conditioner first and then blowing it into the crucible furnace?"

Zhu Youxiao nodded and said, "Well, Sun Qing is very smart. That's what I think. Adding a preheating device to the blower passage and blowing the hot air in may be effective, right?"

That must be effective. Steel mills all have heat storage chambers. The cooling is reduced when blowing cold air. How can it be the same as hot air?

Sun Yuanhua thoughtfully asked, "If you blow hot air on the iron material, you should be able to speed up, right?"

Yes? This is a bit of the meaning of blowing steel, but I don’t know what the difference between blowing air and blowing oxygen?

Zhu Youxiao refused to comment and encouraged him: "Sun Qing can only know if he can succeed if he goes to the test!

After pausing for a moment, Zhu Youxiao quickly changed the subject and asked: "Sun Qing, do you think there are craftsmen in the Weapons and Powder Bureau that suggest casting cannons with iron cores and copper bodies?"

"Long live back, that's true." Sun Yuanhua bowed: "Weichen thinks it is feasible, so he has organized people to conduct experiments. First cast iron tires, wait for them to cool down, and then make molds with clay or lost wax method..."

Zhu Youxiao nodded repeatedly, reached out to interrupt Sun Yuanhua's long story, and said, "No matter whether it succeeds or not, I will reward this craftsman first. Well, Sun Qing, if nothing else, you should step down first, and I still have important things to deal with."

Sun Yuanhua hurriedly stood up, and after he finished showing his salute, he left the palace.

Huh, Zhu Youxiao leaned into the chair and breathed a sigh of relief.

I have been here to be an emperor, not to be a technical mate.

Of course, if I can make money, I don’t mind. Well, when it comes to making money, it seems like it’s going to be soon!

Zhu Youxiao's eyes turned and stopped on a piece of glass on the table.

No one is a fool, and it is impossible to tell if you kill a chicken to warn the monkey. But under the hat of plotting to rebel, no one dares to complain about these people.

On the contrary, the shock showed great effect. The gentry who owed money and food in Jiangnan happily paid all the money and food, while the landlords and gentry who invaded military camps in several northern provinces also quickly returned the military land.
