Bright Sword: I took Li Yunlong to work in military industry

The first batch of molten iron produced from the traditional blast furnace was not directly put into the subsequent refining steps, but was merely used as a test piece to test the reliability of the traditional blast furnace.

Yu Ye and Li Zhengang spent a long time designing this traditional blast furnace, and only started construction after they confirmed that there was no room for modification.

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 here is already of a very high standard.

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.

The scene was very spectacular, just like a bumper harvest of industrial products.

There was a piece of steel billet in front of Li Zhengang. This was the steel he smelted using the pouring steel method. Its properties were much better than those of the molten iron smelted directly from the blast furnace.

"Director, do you think the steel I refine 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, his eyes full of disdain.

"Director, what's going on? Do you think the steel I make is not yours?"

Li Zhengang was somewhat unhappy. He worked hard in Zhaojiayuyu doing design, and after coming back he was doing coking and building blast furnaces, but the factory director still had a look of disdain on his face.

"It's not that it's not right. At least you can carefully check the steel you've made now and pick out the one tenth that is qualified to make gun barrels.

As for the gun barrel?"

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

"What happened to the barrel?"

Yu Ye didn't say anything, he just used his hands to make a gun barrel gesture, and then suddenly let go.

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

"Explosion?"

"Zhengang, that's not a barrel explosion, but an almost unlimited barrel explosion. You have to know that at the moment the shell is fired, the temperature inside the barrel will reach more than 3000 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 of 6 tons on an area the size of a fingernail.

If there is even a tiny bubble or flaw on the barrel, the barrel will explode instantly."

As Yu Ye spoke, he made a "bang" sound with his mouth, which scared 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 the big sinner of the Independent Regiment and Liaoyuan Arsenal.

"Director, what should we do?" Li Zhengang's eyes, which had just been filled with countless hopes because of the smelting of molten iron and steel, were shattered again.

"Let me tell you, Zhengang, this steel can be used to make gun barrels, which means that the crystal form of this steel is extremely clean and stable, and the metallographic structure is very beautiful, which is why it can achieve this goal."

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

"Then, Director, how can we ensure that the steel crystals are stable? And that there are very few impurities?"

Li Zhengang thought about it for a long time and finally gave up, because with his current knowledge, he could not find the answer to the question.

"Master has a secret method to teach you!"

Yu Ye's mouth curled up, and he instantly became amused.

"what?"

A gleam of light appeared on Li Zhengang's dark face, and his eyes instantly became hot.

"Director, please tell me, is there any good solution?"

Yu Ye took out a few pieces of almost torn paper from his back pocket and threw them in front of Li Zhengang: "Here. I will pass on my master's method to you. I hope you will study it well."

Li Zhengang spread out these pieces of paper that looked particularly bad with doubt, and saw a few big words written on the first page: Electroslag Remelting Method.

Li Zhengang was a little skeptical at first when he saw the appearance of this product. After all, how could such high-level metallurgical technology be written so casually on a piece of rotten paper?

This is a blasphemy against cutting-edge technology.

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

"Director, you are so awesome!"

Li Zhengang shouted excitedly. The problem that had troubled him for so long and which he had no idea how to solve with his current level of knowledge was solved just by a few pieces of rags of paper that Yu Ye threw at him lightly.

And the solution was so easy.

There is no worldly air at all.

However, the methods written by the factory director on these pieces of paper were so important that they were so overbearing that they were terrifying.

"Director, can we succeed according to the technology you wrote?"

"Can you remove the word 'ma'? You have been following me for several months. Have you seen me fail in any technical aspects?"

Yu Ye said unhappily.

"Zhengang, come on, take some steel billets and I'll take you to see what it's like."

"what?"

"What are you talking about? I've already prepared the equipment, is there anything strange about this?"

Yu Ye gave Li Zhengang a blank look.

Li Zhengang didn't dare to have any emotions, and quickly called 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 Jue, are you ready for the circuit I asked you to set up?" Yu Ye asked.

"No problem, Director. The wires installed this time can withstand a high voltage of 10kV, which is definitely enough. And this time our three high-power generators are working at the same time, so you can rest assured about the power." Guo Shoujue said with a smile.

"Well!"

Yu Ye nodded.

"Zhengang, put these billets you are carrying into the furnace. Remember to choose a large billet to connect 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 what Yu Ye asked.

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

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

At the same time, there are also a lot of sonic booms produced.

It was as if it was in the most violent thunderstorm, with countless thunderbolts appearing in front of everyone in an instant, looking extremely terrifying.

Even Guo Shoujue, who was in charge of the power wiring, did not expect that the voltage could be increased to such a terrifying level under the action of the transformer rubbed by Yu Ye's hands.

What is more unexpected is that such powerful electricity can also present such a spectacular sight.

In the empty laboratory, various electric arcs appeared one after another, and the crackling sound made people's scalp tingle.

Li Zhengang was stunned.

He never thought that smelting could be so crazy.
