Liang Jian: I will take Li Yunlong to engage in military industry

The first batch of molten iron smelted from the indigenous blast furnace was not directly put into the subsequent refining steps, but was only used as test supplies to test the reliability of the indigenous blast furnace.

Regarding this indigenous blast furnace, Yu Ye and Li Zhengang spent a long time designing it, and only after confirming that there was no room for modification did it officially go into construction.

It can be said that this is the pinnacle of existing technology.

Although it cannot be compared with a real industrial blast furnace or a modern blast furnace, the molten iron produced by this furnace is already of a very high level.

Yu Ye and Li Zhengang squatted not far from the traditional blast furnace, watching pile after pile of materials being added from the charging port, and furnace after furnace of molten iron flowing out from the bottom.

This scene is very spectacular, like a bumper harvest of industrial products.

A piece of steel billet was placed in front of Li Zhengang. This steel was made by the steel pouring method. Its properties are much stronger than the molten iron made directly from the blast furnace.

"Factory director, do you think the steel I made can be used to make gun barrels and cannon barrels?"Li Zhengang knocked on the steel billet in front of him, making a crisp sound.

Yu Ye curled his lips and said nothing, with a look of disdain in his eyes.

"Director, what is going on? Do you look down on the steel I make?"

Li Zhengang was a little unhappy. He continued to work on the design in Zhaojiayu where he lit lamps and boiled oil. After he came back, he made coking and built a blast furnace. In the end, the factory director still had a look of disdain on his face.

"That's not to say it's wrong, at least check it carefully with the steel you've made now, and select only one-tenth of the quality to make the barrel.

As for the barrel?"

Yu Ye didn't say anything, but the disdain in his eyes was still clear.

"What happened to the barrel?"

Yu Ye didn't say anything. He just made a gesture like a gun barrel with both hands, and then suddenly let go.

Li Zhengang instantly understood what Yu Ye meant, which was to explode the barrel.

"Exploded chamber?"

"Zhengang, that is not a chamber explosion, but an almost unlimited chamber explosion. You have to know that at the moment the cannonball is fired, the temperature inside the barrel will reach more than 3,000 degrees Celsius, and the pressure on the barrel is also extremely high. I remember asking you to calculate the instantaneous pressure.

It should be equivalent to applying a pressure equivalent to 6 tons of weight on an area the size of a fingernail.

When there are a few bubbles and flaws on the barrel, the barrel will explode instantly."

Yu Ye said and made a"bang" sound effect with his mouth, which directly shocked Li Zhengang, who was concentrating on thinking about the problem. Li Zhengang could not accept such a scene at all. He did not want to become a major sinner of the Independent Regiment and the Liaoyuan Arsenal.

"Director, what should we do?"Li Zhengang's eyes, which had soared countless hopes because he had produced molten iron and steel, were shattered again.

"Let me tell you, Zhengang, this steel can be used as a gun barrel, which means that the crystallization form of this steel is extremely clean and stable, and the metallographic phase is very beautiful, so that such a goal can be achieved."

Li Zhengang nodded repeatedly after hearing this. This is very important knowledge.

"So, factory director, how can we ensure that the crystallization of this steel is stable? And there are very few impurities?"

Li Zhengang thought for a long time, and finally gave up, because with his current knowledge base, he couldn't find the answer to the question.

"My teacher has a secret method that I want to teach you!"

Yu Ye raised the corners of his mouth and suddenly started to think about it.

"ah?"

Li Zhengang's dark face bloomed with energy, and his eyes instantly became fiery.

"Factory director, tell me quickly, is there any good way?"

Yu Ye took out a few torn pieces of paper from his butt pocket and threw them in front of Li Zhengang:"Here. I have passed on my master's teachings to you, and I hope you will study them carefully."

Li Zhengang spread out these pieces of paper with particularly poor appearance with suspicion, and saw a few big words written on the first page: electroslag remelting method.

Li Zhengang was a little skeptical when he looked at this appearance. After all, How could the extremely high level of advanced metallurgical technology be written so casually on crappy paper?

This was a blasphemy against top technology.

However, as Li Zhengang continued to study, his expression suddenly became serious.

"Factory director, you are so awesome!"

Li Zhengang screamed with excitement. The problem that had troubled him for so long, and which he could not even think of a solution to with his current level of knowledge, was solved by a few pieces of rotten paper thrown over by Yu Ye.

And the solution was still there. It's such an understatement.

There's no fireworks at all.

However, the way the director wrote on these pieces of paper is so overwhelming that it's simply terrifying.

"Factory Director, can it be successful according to the technology you wrote?"

"Can you remove the word '?'? You have been following me for several months. Have you seen any technical failures on my part? Yu

Ye said angrily.

"Zhengang, let's go. You take some steel billets and I'll take you to see them."

"ah?"

"What are you doing? I already have the equipment ready, is there anything surprising about this?"

Yu Ye rolled his eyes at Li Zhengang.

Li Zhengang didn't dare to have any emotions, and quickly called on a few companions to carry a batch of steel billets and follow Yu Ye.

When Yu Ye walked into the laboratory set up in the cave, Guo Shoujue was already waiting. inside

"Shou Jie, I asked you to set up the circuit, are you ready?"Yu Ye asked

"No problem, director, the wires installed this time can withstand 10kV high voltage, which is definitely enough. And this time we have three high-power generators working at the same time, so you can rest assured in terms of power."Guo Shoujue said with a smile.

"Well!"

Yu Ye nodded.

"Zhengang, put these billets you are carrying into that furnace. Remember to choose a large billet and connect it to the electrode.

Don't worry, I haven't turned on the power yet, so I won't do anything to you.���"

Li Zhengang didn't dare to say anything and did all these things according to Yu Ye's requirements.

Due to the harsh conditions and lack of insulating clothing, Yu Ye took everyone to a safe enough distance and activated the relay switch.

As the switch was turned on, a bright arc suddenly burst out in the simple furnace, accompanied by many fine arcs.

At the same time, there were many sonic booms produced.

Just like in the most violent thunderstorm, countless thunderbolts appeared in front of everyone in an instant, which was extremely penetrating.

Even Guo Shoujue, who handled the power wiring alone, did not expect that the voltage could be increased to such a terrifying level under the influence of Yu Ye's hand-rolled transformer.

I never expected that this powerful electricity could present such a spectacular sight.

In the empty laboratory, various arcs were heard one after another, and the sizzling sound made people's scalp numb.

Li Zhengang was stunned.

He never thought that smelting could be so crazy.
