"The minister also knows occasionally, the iron content in its territory is very large, and the steel training is excellent, the minister has a little idea, and wants to practice a batch of steel, which is expected to be used in the coming year, I don't know if His Royal Highness is interested?"

After listening to Zheng Xiong's narration, Zhu Biao was speechless.

As the saying goes: 100 is made into steel.

Listen to this and understand that steel is not so easy to practice.

Your tone is like Chinese cabbage, how much time is there until the coming year? Do you want to get another batch?

"If you don't want much, we can requisition a little bit for you, and go over there to get steel, it's too troublesome, do you think it's okay?"

Don't mention Zhu Biao, whoever hears this kind of big talk thinks it's a joke and won't take it seriously.

Zhu Biao would not take the liberty of interfering in such troublesome matters.

But Zheng Xiong took it seriously, thought about it, and shook his head in a matter-of-fact manner.

"Although the minister doesn't say much, but it's also a lot, hundreds of billions of catties! I wonder if His Highness may be able to get it together? ”

I'll it.

As soon as this number came out, Zhu Biao seemed to have heard it wrong, and turned his head blankly and asked again.

"You're right! 100 catties or 100 billion catties? ”

Zheng Xiong took the tea and drank it all, then stretched out his finger and said with a smile.

"Your Highness heard it right, the minister said that it was 100 billion ~ catties, and it would cost at least 10 billion catties to save a little."

Looking at Zhu Biao's shocked expression, looking like he had never seen the world, Zheng Xiong was extremely satisfied.

Thinking about the productivity at this time, Zheng Xiong still took a step back and lowered the standard.

But there was no way.

I had to cut corners.

The lion's mouth is not like this.

I'm afraid you don't have a good sense of numbers!

Hundreds of billions of catties, it is impossible to make iron, and it is absolutely impossible to make steel.

If there is so much steel, it will be of great use to conquer the Quartet, and it will not be used for you.

You can't even make it yourself.

Zhu Biao seemed to have a windmill on his head, shaking non-stop.

"No, there is no loneliness, there are so many, you can't make it in the future, don't mention it again!"

It's shrinking, but you can't run if you want to.

"Your Highness, don't be in a hurry to deny it, there will definitely not be so much steel in the first batch after the year, but the minister expects it to take a year to do it, and it should be enough by then."

"Besides, a method that can be turned into steel in large quantities, doesn't Your Highness want it?"

The temptation has become a temptation.

Who can resist this.

Zhu Biao can't either.

Use steel to make steel knives, imagine the scene of the official military using steel knives, the Ming Dynasty swept Liuhe, no one can compete with it.

Sighing leisurely, Zhu Biao said with a firm look in his eyes.

"You hand over the method, Lone will show his father, if it is really useful, Lone can promise to give you 100 billion catties in the coming year."

"If you are allowed to come, I'm afraid it won't work."

You're being unreasonable.

I offer you such a great benefit, you give me a hammer to buy.

"Can't Your Highness discuss it anymore? If you let the Prince's Mansion and Ying Tianfu occupy some molecules, it will be more convenient if they want to use it at that time. ”

Zhu Biao's head kept shaking, and he was still a little vigilant.

"What are you going to do! Get so much steel, if you want to rebel, the prince's mansion will not participate, you die of this heart! ”

Hey, you're buttoned up this hat.

I can't take it.

If you really want to rebel, you can still dedicate it to you, I'm afraid it's a dream!

Zheng Xiong was speechless and helpless.

Then there is no way.

mentioned this matter, it was impossible not to hand it over, and Lao Zhu would not let himself go.

I can only hope that Zhu Biao can fulfill his promise and fulfill the steel, otherwise he will lose to his grandmother's family.

"The minister has an open-hearth steelmaking method, and this is dedicated to His Highness."

Zheng Xiong's open-hearth steelmaking method is in line with the current use.

The open-hearth steelmaking method (the open-hearth steelmaking method, also known as the martin method, is now obsolete).

The hock furnace of the open-hearth stove is a groove made of refractory bricks, which is covered by a roof made of refractory bricks.

There is a charging opening on the front wall of the open-hearth furnace from which the loader fills the charge. Close the door caused by the refractory bricks when smelting.

At each end of the furnace are the furnace heads, each with two holes, for the introduction of fuel and hot air, or the use of gas from the furnace.

The raw materials used in open-hearth steelmaking are scrap steel, scrap iron, iron ore and solvents (limestone and quicklime).

At the beginning of smelting, the fuel burns on the surface of the fuel in the face of the introduced hot air, at a temperature of up to 1800 degrees Celsius.

The heat is transferred directly from the flame to the charge, causing the charge to melt rapidly (the melting point of iron is 1535 degrees Celsius, and the melting point of steel is slightly lower).

At the same time, a part of the molten pig iron is formed into ferrous oxide, and the impurities in the pig iron are oxidized by ferrous oxide and sound into slag.

As an excess of limestone is placed in the furnace, impurities such as phosphorus and sulfur form calcium phosphate and calcium sulfide as slag.

Secondly, the carbon is oxidized, and carbon monoxide emerges from the molten metal as if the metal is boiling.

When the anti-bilberry is about to be completed, add oxygen absorber and remove the slag regularly.

At the end of the smelting, the composition of the steel is checked according to the pre-furnace analysis (which can be completed in a few minutes using the rapid analysis method).

The smelted steel flows from the tap port into the ladle, from which it is injected into the mold to cast products or ingots.

In order to increase the furnace temperature, the gaseous fuel is preheated in a regenerator.

In the open-hearth furnace, not only liquid pig iron can be added, but also solid pig iron, scrap iron and iron ore after tapping.

Spread out a booklet written by Zheng Xiong, which was written about the open-hearth steelmaking method.

The method is not difficult, and it is even a little simple.

It's the practical things like the furnace temperature that are difficult.

But there is always a way to overcome it.

I don't know if it's useful, and the right is a feasible strategy.

Zhu Biao said with a smile in his eyes.

"The doctor has a heart, and after his father verifies it, Gu Hui will send 100 million catties to you for use."

"Thank you, Your Highness."

No, I heard me wrong!

"Your Highness is talking about 100 million catties? Is it missing a thousand words? ”

A tooth for a tooth, an eye for an eye.

Zhu Biao looked at Zheng Xiong secretly in his heart, telling you to gasp with me, hang our appetite, now you can taste it!

Zhu Biao was sure and sure, and nodded heavily.

"That's right, it's 100 million catties, is there any problem?"

"Your Highness, you are not joking, didn't you just say that? Have you forgotten what you said about 100 billion catties? ”

Zhu Biao faced the questioning with a calm face.

"How can Lone forget! It's 100 billion catties, yes, but you only have the method of steelmaking, not the method of ironmaking, my Daming only produces 200 million catties of iron every year, and I promised half of it to you, isn't it interesting enough? ”

Interesting enough, indeed interesting enough.

As soon as Zhu Biao's voice fell, Zheng Xiong knew that he was Meng Lang.

Have enough iron.

The yield is definitely high enough.

Because there is no shortage of technology to produce iron.

What is missing is the technology for mining.

At today's level, relying on people to dig slowly, the speed is touching.

However, in this way, the bridge I made by myself is afraid that it will be a tofu scum project!

100 million catties, I don't know if it's enough to put a pillar.

"Your Highness, the minister has a way to produce more, so he has to get a 10 billion catties for the minister!"

"The five-star red flag flutters in the wind, and how loud the victory song is, singing about our dear motherland, from now on to prosperity and strength." The five-star red flag fluttered in the wind, how loud the greeting sounded, wishing my dear friend happiness and health from now on, crossing the mountains of troubles, entering the happy plain, and stepping into the pinnacle of success. 》
