The days when I fished in Daming

"I also know about it occasionally. The iron content in the territory is very high, and it is excellent for steel training. I have an idea. I want to make a batch of steel and plan to use it in the coming year. I wonder if Your Highness is interested?"

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

As the saying goes: Steel is made after a hundred attempts.

After hearing this, you will understand that steel is not that easy to practice.

Your tone is like cabbage. How long is it until next year?Do you want another batch?
"If you don't want much, we can recruit some for you. It's too troublesome to go over there to get steel. What do you think?"

Not to mention Zhu Biao, anyone who hears such nonsense will think it is a joke and will not take it seriously.

Zhu Biao would not rashly interfere in such troublesome matters.

But Zheng Xiong took it seriously. After thinking about it, he shook his head seriously.

"Although I don't say much, it's still quite a lot, maybe a hundred billion catties! I wonder if Your Highness can get it together?"

What the hell.

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

"You're right! One thousand catties or one hundred billion catties?"

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

"Your Highness, you heard me right. What I said is hundreds of billions of catties. If you use it sparingly, it will cost at least tens of billions of catties."

Seeing Zhu Biao's shocked expression, as if 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 his standards.

But there is no way.

We can only cut corners.

The lion doesn't do this even when he opens his mouth.

I'm afraid you are not very sensitive to numbers!
One hundred billion kilograms, it is impossible to make iron, and it is absolutely impossible to make steel.

If there was so much steel, it would be of great use to conquer the four directions, but it would not be used by you.

Not even if you did it yourself.

Zhu Biao seemed to have a windmill on his head, shaking constantly.

"No, I don't have one. You won't be able to create so many in the next year. Don't mention it again!"

It has shrunk, but if you want to run away, there is no way.

"Your Highness, don't deny it in a hurry. The first batch of steel after the year will definitely not be that much, but I estimate that it will take a year to make it, and it should be enough by then."

"Besides, wouldn't Your Highness want a method that can turn steel into large quantities?"

Follow the temptation and become the inducement.

Who can resist this.

Neither can Zhu Biao.

Use steel to make steel knives. Just imagine the scene where the officers and soldiers use steel knives. It is easy for the Ming Dynasty to sweep Liuhe, and no one can compete with it.

Zhu Biao sighed leisurely and said with firm eyes.

"You hand over the method and I will report it to Father Ming. If it is really useful, I can promise to give you hundreds of billions of catties in the coming year."

"I'm afraid it won't work if I ask you to come."

You are unreasonable.

I have given you such a great benefit, and you give me a one-shot deal.

"Your Highness, can't we discuss it further? It would be more convenient if the Prince's Mansion and Yingtian Mansion take over some of them if they need to be used at that time."

Zhu Biao's head kept shaking, still a little wary.

"What are you going to do! With so much steel, are you planning to rebel? The Prince's Mansion will not participate, so give up!"

Hey, your hat is on.

I can't take it.

If I really want to rebel, I can dedicate it to you. I'm afraid it's just a dream!
Zheng Xiong was speechless and helpless.

Then there's no way.

After mentioning this matter, it was impossible not to hand it over, and Lao Zhu would not let him go.

We can only hope that Zhu Biao can fulfill his promise and deliver the steel, otherwise he will lose money to his grandma's family.

"I have an open-hearth steel-making method, which I would like to offer to Your Highness." The open-hearth steel-making method Zheng Xiong mentioned is in line with current use.

The open-hearth steelmaking method (the open-hearth steelmaking method is also called the Martin method, and has now been eliminated).

The hearth of an open-hearth furnace is a trough made of refractory bricks, covered by a furnace roof made of refractory bricks.

There is a charging port on the front wall of the open-hearth furnace, and the charging machine loads the furnace materials from here.Close the door made of refractory bricks while smelting.

There are burners at both ends of the furnace, and each burner has two holes for introducing fuel and hot air, or for guiding furnace gas from the furnace.

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

When smelting begins, the fuel burns on the fuel surface when it encounters the introduced hot air, with temperatures as high as 1800 degrees Celsius.

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

At the same time, part of the melted pig iron generates ferrous oxide, and the impurities silicon and manganese in the pig iron are oxidized by the ferrous oxide and become slag.

Because there is excess limestone in the furnace, impurities such as phosphorus and sulfur generate calcium phosphate and calcium sulfide and become slag.

Secondly, the carbon also undergoes oxidation, producing carbon monoxide that emerges from the molten metal as if the metal is boiling.

When the deoxidation process is about to be completed, deoxidizer should be added and the slag should be scooped out regularly.

When smelting is about to be completed, it is necessary to check whether the composition of the steel meets the requirements based on pre-furnace analysis (using a rapid analysis method, which can be completed in a few minutes).

The smelted steel flows into the molten steel ladle from the steel tap, and then poured into the mold from the molten steel ladle to be cast into products or steel ingots.

In order to increase the furnace temperature, the gaseous fuel must be preheated in the regenerator.

Not only liquid pig iron can be added to the open hearth, but also solid pig iron, scrap iron and iron ore after pinching can be added.

Opening up a pamphlet written by Zheng Xiong, it was written about the open-hearth steelmaking method.

The method is not difficult, even a bit simple.

The hard part is practical things like furnace temperature.

But there are always ways to overcome it.

I don’t know if it’s useful, but I’ll take it as a feasible strategy.

Zhu Biao said with a smile in his eyes.

"The medical lord is interested. After the emperor father has verified it, I will send you a hundred million catties for your use."

"Thank you, Your Highness."

No, I heard it wrong!

"Your Highness said billions of catties? Is there a thousand words missing?"

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

Zhu Biao looked at Zheng Xiong with a feeling of joy in his heart, asking you to gasp with me to whet our appetite, now you can taste it!
Zhu Biao was certain and affirmative, and nodded heavily.

"That's right, it's [-] million pounds. Is there any problem?"

"Your Highness, Jun Wuxi, isn't that what you just said? Have you forgotten the one hundred billion catties you mentioned?"

Zhu Biao looked calm when asked.

"How could I forget it! It's a hundred billion kilograms, yes, but you only have the method to make steel, not iron. Our Ming Dynasty only produces [-] million kilograms of iron every year. I promised you half of it. Isn't that interesting enough? "

Interesting enough, indeed interesting enough.

As soon as Zhu Biao finished speaking, 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 lacking is mining technology.

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

However, in this case, the bridge built by myself will probably be a shoddy project!
One billion kilograms is enough to even put a pillar on it.

"Your Highness, I have a way to increase production. No matter what, I have to get tens of billions of kilograms for you!"

"The five-star red flag is fluttering in the wind, and the victory song is so loud, singing that our dear motherland will become prosperous and strong from now on."The five-star red flag is fluttering in the wind, and the greetings are so loud. I wish my dear friend to have happiness and health from now on, to cross the mountains of trouble, to walk into the plain of happiness, and to reach the pinnacle of success. 》
