The smelting method that Chu Ze gave to Li Xing was the concentrate blast furnace smelting method in the fire method copper smelting.

The blast furnace is a vertical furnace, and it is very convenient for China to directly smelt copper. This method is also known as sintered block blast furnace smelting method, which is to sinter copper sulfide concentrate through sintering to remove part of the sulfur to make sintered blocks, and add it to the furnace in layers with flux and coke according to the batch of materials. Copper matte and waste slag produced by smelting.

The problem is that it is not conducive to the recovery of sulfur.

And now Chu Ze taught Li Xing the method, but it can reduce air leakage while increasing the concentration of sulfur dioxide.

Chu Ze tilted his body, pinched the peanuts in his hand and peeled them, threw one into his mouth after peeling one, and slowly spit out one noun after another in his mouth: "Mix the copper sulfide concentrate into a paste, and then add some lumps, fluxes, coke, etc. to the furnace from the central feeding port of the top of the furnace in batches to form a material seal, reduce air leakage, and increase the concentration of sulfur dioxide." ”

The pen in Li Xing's hand moved rapidly.

After Chu Ze finished speaking, Li Xing also finished remembering.

He raised his head and looked at Chu Ze suspiciously: "What is sulfur dioxide?" ”

"Uh......" Chu Ze's voice paused, the speed at which he peeled peanuts stopped, he turned his head sideways at Li Xing, thought about it, and said in a more understandable language, "You can simply understand it as a very stingy gas, if it is used well, it is a good thing, if it is not used well, it is a murderous thing." ”

After hearing this, Li Xing felt even more curious.

"You can't see or touch the air, how do you know that?"

Of course, I stepped on the shoulders of giants and saw it.

Otherwise, do you expect him to find out for himself?

Chu Ze thought that he didn't have such a big ability.

"You use our method, and then use some special methods, you can also see it."

As soon as Chu Ze finished speaking, he saw Li Xing's eyes suddenly brighten up.

Chu Ze nodded: "Naturally, it's true." ”

When the kneading material is dried and roasted by hot smoke in the furnace, a sintered column will be formed. The bulk material is also surrounded by columns around the sintered material column to maintain air permeability, which can increase the concentration of sulfur dioxide and ensure the normal progress of smelting.

During the smelting process, sulphur dioxide appears, which can be collected using a set of equipment.

The previous processes are easy to say, but the two links of dust collection and fog removal make Chu Ze a little difficult.

In modern times, where there is a lot of electricity, as long as these machines can be made, they can naturally operate. But in the Ming Dynasty, whose cognition of electricity is only on lightning, it is very difficult to run such a set of equipment.

Not only did he need to make the equipment, but he also had to think of a source of energy that could be replaced.

Although Chu Ze now plans to make a steam generator, it is still not enough.

There is certainly not a small amount of electricity that a factory needs.

The steam generator he envisioned now was probably not enough.

He had to keep thinking.

After listening to Chu Ze's narration, Li Xing recorded it word for word.

He was afraid that he would remember wrongly, so he deliberately asked Chu Ze to read it, and after confirming that it was correct, he put away the paper and turned his head to find the carrier pigeon, intending to send the letter back to Taiwan.

When he came back, Chu Ze was lying on the side of the desk, holding a pen in his hand, writing and drawing on paper.

He saw that Chu Ze was writing seriously, so he didn't make a sound, but walked over lightly.

When I got closer, the man didn't even notice him.

Li Xing didn't make a sound to remind, so he stretched his neck and looked at Chu Ze's paper.

After looking at it for a long time, Li Xing only saw a few big circles and small circles, but other than that, he didn't understand anything.

The rest of the ghost talismans are even more incomprehensible.

He looked at it twice and left in disgust.

When he was about to step out of the study door, Chu Zecai lifted his eyelids and glanced at him, but he didn't look up, and then continued to bow his head to paint.

If he wants to make a generator, he has to ask for copper wire.

Copper is also used a lot now, and there are also copper wires.

But those are all used to decorate crafts and so on.

What Chu Ze wants is copper wire that can be used on generators, which requires higher copper wires.

It is better to be able to speed up production.

Only in this way can he be able to supply copper wire when he needs to use a lot of copper wire in the later stage.

After Chu Ze drew a few strokes, he put the pen down again.

He stood up, spun around twice behind his desk, and then changed his clothes and went out.

There were some things he didn't remember well, and he needed to find inspiration.

The so-called inspiration is naturally to see how others make copper wire.

As far as he knew, there was a craftsman in the northern city of Yingtianfu.

However, the handicrafts made by this person are not copper wires, but bamboo strips.

The bamboo products he made are exquisite, and the bamboo strips are trimmed to be extremely delicate, like a girl's skin. Therefore, his works are very popular in Yingtian.

Although making bamboo strips has nothing to do with making copper wire, some of the things used in the production process have some relevance.

For example, round knives.

Chu Ze asked Zhao Si to set up a good car and set off straight towards Beicheng.

Beicheng is very lively, and it is a gathering place of three religions and nine streams.

Along the way, people came and went, shouting and trading, as well as juggling, and selling their own mysterious prescriptions, Chu Ze even saw one who sold his daughter.

Chu Ze glanced at it twice, threw a silver ingot to Zhao Si casually, and said, "Give it to that person." ”

Zhao Si followed Chu Ze's gesture and looked over, and saw the mother who sold her daughter at a glance.

The daughter he sold was not very old, and she was quite handsome.

Zhao Si's first reaction was: "The master has taken a fancy to that girl?" ”

Chu Ze's face darkened.

"Can we fancy her? For a person with big beans, let her serve tea as high as a tea bowl. The lord is kind today, go and give it to her, and no one will have to take it back. There is a big family in the house, so I don't need her. After Chu Ze finished speaking, he retracted into the carriage, he leaned on the wall of the carriage, but his heart was very heavy.

Although the sale of sons and daughters has existed in all dynasties.

But the people of the Ming Dynasty seem to have a more difficult time.

I don't know if Zhu Yuanzhang killed too much and offended God. During the reign of the Ming Dynasty, various natural disasters took turns.

It's really you singing and I'm on the stage.

It's very lively.

It is the misery of the people.

People's livelihood has to be changed.

Chu Ze began to worry again.

"Sir, it's here." The carriage stopped on a street, and Chu Ze got out of the car when he heard the sound.

Before he could touch the ground, he saw a small shop full of people.

They squeezed me and I was next to you, and craned their necks to look in.

It's like you're looking at something lively.

Chu Ze was immediately attracted.

He jumped out of the carriage and plunged straight into the crowd.

Anyway, I came out to find inspiration, and watching the excitement can also inspire inspiration.

Chu Ze squeezed to the front after two or three clicks.

One look -

Yo, old trick. (End of chapter)
