On the eve of the anti-eagle movement: the country urgently called me back home!

Jiang Chen:”The outlet of the furnace is blocked by slag and needs to be cleaned. At the same time, there should be something wrong with the cooling valve!”

During the steelmaking process, various impurities in pig iron, such as silicon, manganese, phosphorus and sulfur, react with oxygen at high temperatures to form oxides.

These oxides can be in liquid, solid or gaseous form, and they react with the furnace lining and the flux added to the furnace at high temperatures to form slag.

Slag helps to separate these impurities from the molten steel, thereby improving the purity and quality of the steel.

In converter steelmaking, liquid pig iron is injected into the converter, flux such as quicklime is added, and air or oxygen is blown in to oxidize elements such as iron, silicon, and manganese to form slag.

Over time, the slag naturally forms a block and blocks the outlet of the valve, preventing the molten iron from flowing out.

Zhao Tiechi nodded:”Before, Lao Meng also guessed that this was the problem, but the inlet valve was too small, and even if it was blocked by slag inside, it could not be cleaned!”

People can’t get in

“This slag has not been cleaned for so many years. Even if we chisel it out, it will take a year or so!”

It is difficult to deal with even if we know the problem.

Jiang Chen:”If you want to clean the slag in the furnace, you don’t need to disassemble it. Just add ammonium nitrate. By cooling the high-temperature slag, it will solidify quickly and form a solid block.”

“This method is not only convenient to handle, but also fast and low cost.”

“However, it is worth noting that if the cooling speed is too fast, the residual high-temperature gas in the slag cannot be completely removed, thus affecting subsequent processing.”

“Therefore, after the high temperature is formed, it is necessary to accelerate the addition of cleaning agent (composed of ammonium nitrate and other materials) and repeat it several times until the valve can open normally!”

“However, the cooling valve must be repaired before that!”

After listening to Jiang Chen’s analysis, everyone was stunned and shocked.

Zhao Tiechi asked in disbelief:”Comrade Jiang Chen, can the No. 4 furnace really be repaired?”

“Of course!”

Lao Meng said:”But now Anshan doesn’t even have valve parts, how can we repair it? ?”

“Hey, this is easy. Just remove one of the cooling valves of furnaces 1, 2, and 3, right?”

“Now that we have repaired furnace No. 4, the issue of valve parts will not stump you!”

“Yes, why didn’t I think of that!”Old Meng suddenly realized and started to operate.

Everyone was stunned by Jiang Chen’s operation and maintenance knowledge.

This foreign student is really good!

Li Yunlong and Brigade Commander Chen showed admiration.

The boss really liked the right person.

“Come, start a fire……”Lao Meng directed the workers of Anshan Iron and Steel to start adding coal to the coal furnace.

At present, Anshan Iron and Steel uses coal furnaces instead of electric furnaces.

“Master Meng, isn’t furnace No. 4 repaired yet?”

“I hope our efforts in starting the furnace will not be in vain!”

“Just do what you are told to do, why are you talking so much nonsense.”Zhao Tiechi didn’t say much.

The workers started to get busy.

In the next two days, Jiang Chen, Li Yunlong, Brigade Commander Chen and others were all at Anshan Iron and Steel.

What Jiang Chen couldn’t believe was that the food allowances of the workers at Anshan Iron and Steel were extremely poor. Steamed buns and white porridge were a luxury.

Not to mention chicken, pork and other meats.

After asking, he learned that the country was currently in a difficult period, and eating was the biggest problem.

Four hundred million compatriots, that is, four hundred million people.

It is really a big problem to solve the problem of eating for these hundreds of millions of people.

“It’s out, it’s out!”

A shout rang out in the silent factory, and Zhao Tiechi, Shen Feixue and others quickly rushed towards furnace No. 4.

The next second, the two shouted excitedly:”Haha, it’s true… this is true……”

“Furnace No. 4 has really been repaired!”

As soon as Zhao Tiechi said this, all the workers in the workshop shouted excitedly.

The workers in the Anshan Iron and Steel Workshop knew about the problem with Furnace No. 4.

When they learned that it had been repaired, the whole workshop was immediately shocked.

“What? The iron lion in furnace No. 4 has been repaired!”

“Hahaha… it’s true… it’s really fixed… who did it? ? Who is so awesome?”

“It is said that it is a big leader from above!”

Suddenly, people in the crowd began to look for Jiang Chen.

For these ordinary workers, opening one more furnace means more work and more food.

Zhao Tiechi took Jiang Chen’s hand and said,”Comrade Jiang Chen, thank you so much!”

“Thank you for giving No. 4 furnace and Anshan a chance to be reborn. I thank you on behalf of 3,420 workers in Anshan.”

Lao Meng:”As a master in Anshan, I really admire you today. Please accept my greetings.……”

Jiang Chen:”Master Meng, Director Zhao, you are too polite. We are all working hard for the construction of New Rabbit!

“I hope our motherland will become better and better. Thank you for your hard work. I also hope that the order from Shenyang Arsenal can be expedited in the future!”

“This is a must……”Zhao Tiechi:”By the way, Comrade Jiang Chen, will there be more orders for the arsenal in the future?”

“Of course, our arsenal will have to build its own aircraft, tanks, ships and aircraft carriers in the future. Which one can be made without your steel!”

Zhao Tiechi and others were ecstatic and excited.

The arsenal wants to build its own aircraft, tanks, warships and aircraft carriers?

They can’t do without Anshan Iron and Steel.

As a”steel man”, Zhao Tiechi and other workers are full of hope and expectation for the future.

Afterwards, Jiang Chen handed over some smelting technology, how to increase the hardness of steel, and how to increase production capacity to Zhao Tiechi and Shen Feixue.

When the two heard it, they immediately felt like they had found a treasure and almost knelt down to Jiang Chen.

They admired him very much.

“Jiang Chen, you are simply a smelting expert!”

Jiang Chen let them know what special steel is, what aluminum alloy (stainless steel) is, and what titanium alloy (steel) is.

My goodness, is foreign technology so advanced?

It seems that we have to work harder!

For a while, the technicians and experts of Anshan Iron and Steel were full of motivation and enthusiasm.

They must produce steel that is more advanced than the world.

“Comrade Jiang Chen, I assure you that while ensuring the quality, Anshan’s output will double within one month and triple within three months!”

“OK, I’ll be waiting for your good news at Shenyang Arsenal.……”
