The Head of the Ming Dynasty Spared His Life

Yan Song suddenly looked disgusted: "Anyway, you don't understand it, go play around!"

Hai Rui squatted in the corner silently, his heart hurt.

Chapter 470 Open the furnace!Steelmaking! 【2】

Xu Xiake took his hands to survey the terrain, while Yan Song, Hai Rui and others continued to inspect the steel plant.

Hai Rui was still a little unconvinced: "Elder Yan Ge, although you have blown steel and cement into the sky, I only believe in the method of my ancestors. Big stone + burnt bluestone bricks + white ash rice soup is the only way to build a city. What kind of steel cement is this, does it really work?"

The more he talked, the more excited he became: "Although I, the deputy director of the Municipal Bureau, was recommended by you. But I, Hai Rui, am an unselfish person. If you, Yan Song, appoint private individuals and change the method of building the city privately in order to gain profits, As a result, Tianjin’s new city and port have turned into bean curd projects, I will definitely report to the emperor based on the facts! I don’t care about it at all!”

Hai Rui has such a bad temper. When he saw what kind of cement factory and steel factory Yan Song was, it seemed that these big businessmen also had a deep relationship with him. The construction had already started half a year in advance, so he began to suspect that Yan Song was a treacherous minister. , Are you going to engage in trickery again, engage in tofu dregs projects, and defraud construction funds?

Yan Song was speechless.

It was really not easy to convince this bad-tempered Hai Rui.

"Since what you say is unfounded and what you hear is false, then seeing is believing!" Yan Song pointed at Hu Xueyan: "How about you actually make some steel bars and make them into something I'll give you, [Reinforced Concrete Method] , let our Hai Qingtian take a look!"

Only then did Hai Rui snort coldly, expressing his approval.

Many business tycoons are also watching curiously, what exactly is this [reinforced concrete method]?

Except for Yan Song's top ten businessmen, Qiao Zhiyong and other absolute confidantes, other tycoons don't know much about Yan Song, let alone why Yan Song can have new terms popping up one after another, endlessly.

Hu Xueyan, a steel tycoon, smiled slightly, pointing to a row of newly built steel cave furnaces and said: "Fortunately, our process is simple. We can already start making steel bars. Then, old Qiao, your cement is all right.~? "

Qiao Zhiyong smiled and said, "My cement is all cement powder, which has already been shipped. It depends on you."

Hu Xueyan gave an order and turned on the stove!

Hai Rui and the other tycoons stretched their necks and looked at the cave-like steelmaking furnaces.

Steelworkers are very skilled at pouring truckloads of pig iron, quicklime, coke, and scrap steel into the feed port above the steelmaking furnace in the cave dwelling, and then use well-mixed cement to completely seal the cave dwelling, leaving only the top There are two stirring ports and an outlet for the molten steel below.

These workers are also skilled workers, with tacit cooperation and high efficiency.

Yan Song smiled, the crucible steelmaking method, in fact, is to reduce and replace the impurities and carbon elements in iron with coke lime in an oxygen-free high-temperature environment, turning pig iron with a carbon content of more than 2% into steel with a carbon content of 0.5%. It's that simple.

The workers put the oil that had been simply purified to remove impurities into the burner under the cave, and then evacuated the steel-making furnace of the cave.

ignition!

A lot of thick smoke came out of the oil. Although it has been purified, it is not like high-purity diesel oil. There are still a lot of impurities in it. Fortunately, there will be no explosion, but the smoke is very large.

However, this steel factory is by the sea, and the sea breeze is very strong, so it will blow away quickly, so it will not cause too much pollution.

After burning at high temperature, the pig iron and other raw materials in the cave will soon start to react.

The steelworkers keep increasing the fuel to maintain the extremely high temperature in the cave, which must reach 1200 degrees. At the same time, they keep opening the upper furnace mouth to keep stirring with the steelmaking machine to ensure that the reaction is basically uniform and the quality of the steel produced.

The high temperature above [-] degrees made everyone sweat profusely.

Hu Xueyan praised: "Yan Ge is old and smart, and set up a steel factory by the sea. The temperature here is extremely high, and some fuel can also be saved."

Half a day later, steelmaking ended.

Steelworkers opened the drain.

Hot red molten steel flowed out, burning everyone's faces red.

Yan Song watched Daming's first furnace of industrial molten steel roll out, let alone the excitement in his heart!

Under his strategizing, Daming finally smelted the world's first batch of industrialized steel 300 years ahead of the West!

Steel is a great weapon of great powers!

Even in World War II and even in modern society, steel production is still an important indicator of a country's overall national strength and war potential.

The reason why Japan lost to the United States in World War II, Germany lost to the Soviet Union, and steel production could not keep up is an important reason.

With this industrialized steelmaking method, Ming's architecture, industry, navigation, and military technology will all advance by leaps and bounds!

Yan Song's heart was surging, he laughed straight away.

This crimson molten steel, like magma, in his eyes, is the future of Daming and himself.

Hai Rui looked at the excited Yan Song, and muttered, "I'm sick."

After reading a lot of sage books, he believes that everything is inferior and only reading is high.

What steel, what cement, what shipbuilding, are not as important as sage books.

Steel workers skillfully guide the molten steel into the mold.

The mold is also made in advance, and its temperature resistance is much higher than that of molten steel, so it will not deform.The hot molten steel flowed obediently into the mold.

According to the continuous rolling process of later generations, molten steel can be easily continuously rolled into any shape such as coils, plates, steel bars, etc., but it is a pity that this is Daming, and there is no electricity, so it can only rely on manpower.
