The Supreme Prosecutor of the Tang Dynasty

Chen Qiu personally supervised the work, and in just half a day, the prototype of the steelmaking furnace was erected.

Looking at the steelmaking furnace that basically met the requirements, Chen Qiu finally nodded with a smile.

Immediately, he saw Zhou Kang with a sad face on the side, and couldn't help but chuckle: "What, you're worried?"

"Master, this ...... Zhou Kang was indeed a little worried. "

"Time is too short, even if there is no problem with the furnace this time, we don't have enough time to find a suitable blacksmith and start working on it!"

In Zhou Kang's concept......

The role of the steelmaking furnace, that is, it is similar to that of ironmaking, even if there is a difference, it is not big.

Is it so easy to make iron?

After ironmaking, at the very least, you have to build it, right? After it is built, you can price it according to cost and quality.

Taking a step back, even if everything is going well, what if the cost is too high?

"There's nothing wrong with the idea, but you've made a mistake!"

Chen Qiu shook his head with a smile, and then said softly: "Fang Cai, I have already said that this furnace is not used for smelting iron!"

"Isn't it iron-making?" the master did say that, but ...... Zhou Kang was even more curious. Zhou Kang frowned: "If you don't smelt iron, what is this furnace?"

"Steel-making furnace, that's the name of this furnace!"

"Steel-making furnace?" Zhou Kang wondered.

"Steel-making furnace, steel-making furnace, as the name suggests, smelting, is naturally steel!"

Chen Qiu smiled confidently......

Perhaps, if you use the original equipment and manpower of this blacksmith shop, if you want to wrestle with the private iron of the family gate, it is really not a small difficulty.

Can...... Who told you that I was going to make iron?

Official salt, official iron?

Sorry, if you want to play, let's play the more advanced ones, let's ...... Direct steelmaking!

The conditions required for steelmaking are somewhat harsh, and the first and most important point is temperature!

Without enough temperature, it is impossible to make steel, which is why Chen Qiu is so concerned about the steelmaking furnace!

This steel-making furnace is a kind of furnace designed by him according to the technology in steel-making and combined with the current actual situation.

This kind of furnace, after being sealed, is heated violently, and it can fully meet the temperature standard required for steelmaking.

So dependent, the biggest problem of steelmaking was naturally solved by him!

As long as the furnace can be built, the problem of temperature is no longer a problem!

As for how to make steel, Chen Qiu naturally belongs to his heart.

The steelmaking technique from the system was like a kind of secret book, Chen Qiu opened it directly, as if he had been empowered, and directly memorized all the knowledge in it.

Even, it can be said that it is backwards,!

In this case, steelmaking is not a big problem!

As long as there is a high enough temperature, the impurities and carbon content in the pig iron can be eliminated, the carbon content is reduced, and the purity and quality of the iron are better!

In fact, that's just the quality of private iron.

But...... Chen Qiu wants more than that!

Iron with higher purity can certainly beat private iron, but the degree is limited, it is not explosive enough, or in other words, it cannot meet the requirements of Chen Qiu's heart!

Therefore, only steelmaking can be regarded as real satisfaction.

In steelmaking, when pig iron is constantly refined, impurities are constantly removed, and the carbon content is lazier and lower, some unique substances are added to carry out chemical reactions.

To put it simply, steel is actually an alloy!

At a high enough temperature, add the right material to catalyze an alloy, and this alloy is steel!

The hardness of steel is much higher than that of iron!

At the same time, the durability is also better, and it is used to build agricultural tools, which is enough to press the iron to the ground and rub it in all directions!

Of course, steel also has a disadvantage, that is, it is too hard and not elastic!

The so-called steel is easy to break, and this is the truth.

But this problem is not impossible to solve.

In steelmaking, there is a solution to this problem. Even, even if there is no way, Chen Qiu has a way to get it done.

The most common is the cladding method!

One is the forging technique that was born in the Tang Dynasty, but it has not yet been invented.

In later generations, it was extremely famous for the Tang horizontal knife forged by the Baotou steel method in the Tang Dynasty!

The exterior is steel, but the inside is wrapped in a very pure iron, which is then forged......

The Tang horizontal knife forged by this method is not only extremely sharp, but also extremely elastic and tough! Even if it is chopped on a hard corbel bone, it will not break, and even if it is built well enough, even a gap will rarely appear.

If a person studies these things from scratch, let alone a month, even if it is a year or even ten years, it may not be enough!

But for Chen Qiu, ten days is enough!

After all, he doesn't need to study anything by himself, all kinds of means and techniques are all in his head, and when he needs it, he can directly take it out and use it, and he is afraid of asking for it?

However, Zhou Kang was still a little confused: "Dare to ask the master, what is steel?"

"Steel?"

Chen Qiu shook his head and smiled: "To put it simply, it's ...... Harder, sharper, and more precious than iron!"

"There's hardly much comparison between the two!"

"Under the steel sword, the iron sword and the iron sword, although not as fragile as tofu, will never be so hard. "

"Well, looking at your bewildered look, no matter how much you say, you can't understand. "

"Look at this progress, tomorrow at noon, the stove will be about the same, let's come back tomorrow, when the time comes, let you see and understand, what is ...... Steel!"

Chen Qiu shook his head and smiled, and left with Zhou Kang.

And many inspectors are still busy, meticulously building steelmaking furnaces.

...... (Deli Hao)

Vertical sun, noon.

It was the time for lunch, and the smell of food came out from every house, and the autumn sun was not too hot, and it was a little warm on people.

Because the refined salt was sniped by the snow salt, it was almost killed directly, so the major families were in a hurry, so their private iron was all reduced in price again!

All kinds of iron tools, whether it is farm tools, kitchen supplies, etc., or knives, guns and sticks, etc., the price has been reduced again!

Before this, the price of private iron was lower than that of official railway, and now, it has been reduced twice in succession, making the price of private iron low to a level that makes it difficult for the people to calm down.

Yes, the business of private railways has been much better in the past two days!

Even if you have a kitchen knife at home...... But, at such a low price, isn't it a good thing to buy more?

Those who are in the rivers and lakes are even more so......

Walking the rivers and lakes, how to play with a few weapons at hand?_
