Daqin: Qin Shihuang Visited The Stalls At the Start

Chapter 148 Let you see, what is advanced steelmaking technology!

At this time, Su Yu was spending money on the construction site.

Thermal insulation exterior building materials? Buy!

Waterproof paint? BUY!

Wall putty paint finish? BUY!

Various modern decoration materials continue to appear in the houses that have already laid water pipes and are considered semi-finished products.

And these things also cost him two to three million funds.

But Su Yu was - not at all distressed.

After all, isn't his purpose of making money just to finally be able to return to a convenient modern life again?

After all, he is now fulfilling his ideals.

Of course, there are some things that can be replaced by Daqin's existing materials, and Su Yu didn't spend any money.

For example, the blue bricks used for building walls, and the floor tiles that need to be laid indoors.

They are all directly found in the stone workshops outside Xianyang City for processing and polishing.

Including the indoor floor and a small part of wooden furniture, the carpenters are also in the process of rushing.

The whole house is nearing completion.

The rest is the greening and landscaping in the courtyard.

With these things, you can ask Lao Zhao for some people who will be the young mansion.

After all, people are official positions that came into being in order to build houses and gardens.

"Su Yu!

Just as Su Yu's thoughts fell, Lao Zhao's voice came from the door of the construction site.

"Yo, Lao Zhao, some days are gone. 99

Su Yu's face brightened with joy.

There is something to say.

I'm dozing off, so here comes the pillow!

However, before Su Yu spoke, Lao Zhao spoke first.

"Su Yu, I'm here today to ask you for help. Nian

The smile on Su Yu's face was even bigger: "It's easy to talk, what's the matter?

"It's about the method of making steel, I wonder if you can master it?"

"Oh?"

The smile faded, and Su Yu knew that it was no trivial matter when it came to making steel and iron.

Rather, it involves the great event of Daqin's national strength.

Old Zhao said sternly: "Now the DPRK and the Middle Kingdom have set up a special iron smelting palace, and they have collected my famous iron smelting officials in Daqin. 99

"However, the output of Hundred Steelmaking is still extremely low, and even the horseshoes and stirrups needed by the army cannot be supplied.

"Although it is true that there is a lot of bronze in the production of steel, but with such an output, it shouldn't be able to reach the level Su Yu said, right?

In the face of Lao Zhao's doubts, Su Yu did not directly explain.

Instead, he said: "Daqin Bai's steelmaking is just the most basic and backward ironmaking technology, give me a few days to show you what advanced steelmaking technology is.

Lao Zhao did not stay at the construction site for too long.

Because recently, due to the implementation of various systems and the response to measures to restore the status of businessmen, political affairs have been busy.

It doesn't take much free time.

After Lao Zhao left, Su Yu briefly instructed the glorious hard workers in the construction site, and also left the construction site and took a group of craftsmen with him.

At this time, the big cow is sitting at home and resting.

Since the main body of Su Yu's house has been completed, he no longer has to work hard to burn cement ash.

The half a million dollars he earned from Su Yu was enough for him to spend his entire life.

"Big cow! Are you resting?"

"Su Yu? Why are you free to come and see me? Hurry up and sit down." When the Daniel saw Su Yu approaching, he quickly got up and came over to greet him.

Su Yu waved his hand and said, "I came to you again today for help."

"What? Are you going to start firing glass?" Daniel's eyes lit up and he started rolling up his sleeves.

"It's not about burning glass." Su Yu smiled slightly: "I'm looking for you today because I want you to help make steel!

In fact, ironware was already popular during the Spring and Autumn Period and the Warring States Period.

There are even the earliest quenching techniques.

However, compared to the bronze weapons at that time, it is still slightly inferior.

Even in Daqin, Hundred Steelmaking, which has begun to develop gradually, is in the final analysis, it is only the earliest piece of steelmaking.

There is still a huge gap between the real steelmaking in the Han Dynasty and even later.

Since only the use of charcoal calcination was used in this period, the temperature was limited.

Only iron ore can be fired into relatively pure iron particles and slag, which are sponge-like.

Although the purity of iron particles is relatively high, during the distribution of impurities aggregated into a large amount of slag, a large amount of forging is required to discharge the slag.

And because of the problem of metal fatigue, forging has a limit after all.

Therefore, the block iron products still contain a lot of impurities as a whole, which also seriously affects the performance of the iron, which is greatly detrimental to the toughness and strength.

Until the later period, the Western Han Dynasty began to use coal to make iron.

The high temperature far exceeds the high temperature produced by charcoal, which makes the technology of frying steel appear.

Since then, the output and performance of steel has also begun to have a leap forward.

With the emergence of the steel pouring method during the late Han and Northern and Southern Dynasties, the output of steel increased again.

A variety of forging, casting, quenching, and grinding techniques have also blossomed.

But that's all for later.

What Su Yu wants to do today is to bring this method of pouring steel over.

The premise of this steel filling method is the steelmaking furnace.

After all, what this thing uses is the high temperature generated by coal, which is far from what an ordinary smelting furnace like the Daniel family can produce.

"Steelmaking?" When the Daniel heard Su Yu's words, he showed an excited look.

This is his ancestral craftsmanship.

However, before he could speak, Su Yu spoke again: "The way we are today is not the same as what you have been in contact with before. 55

The voice fell, and he clapped his hands.

A group of craftsmen came in through the door.

Looking at Daniel's puzzled face, Su Yu explained: "This time, because of a different approach, we are going to rebuild a steelmaking furnace."9

"When the time comes, it will not be a dream to produce 10,000 catties of steel per day!" And.
