Siheyuan: Craftsmen of a Great Country

Chapter 287 Converter Steelmaking Successful
"So, there was an accident in this experiment, but only one worker was injured and there were no other losses?"

Yang Weimin, who was waiting for Jiang Chen at the entrance of the laboratory, confirmed after listening to his story.

Jiang Chen nodded: "Well, there are no other major losses. However, the converter may be damaged to a certain extent. Su Gong and others are inspecting the specific situation."

"However, visual inspection has little impact, because the amount of molten iron in the charge during our experiment was relatively small, and the converter construction was relatively strong."

Tao Yuan pondered for a moment, then slowly said: "Xiao Jiang, if this research is too dangerous, just let it go."

"Your safety is more important than anything else."

Jiang Chen waved his hand: "During the experiment, Su Gong and the others were the ones operating it, and I was watching from a distance. Don't worry, I care more about my life than you think."

"Now flower growers really need a more advanced and efficient steel-making method."

Tao Yuan sighed. How could he not know the importance of steel?

Otherwise, the flower growers would not be so desperate as to make steel.

"What if, I mean what if an accident happens and you are disfigured during the experiment?"

The reason why he told Shangguan Wan'er the truth and said such things was actually to test the other party.

Shangguan Wan'er came to his side: "Leader, did the explosion just come from the laboratory?"

Jiang Chen hesitated for a moment, but still did not hide anything: "Yes, an accident occurred in the laboratory while conducting experiments. A worker's leg was injured in the explosion. Fortunately, his life is not in danger."

"If something happens to you, Mr. Zhou will probably eat us up before the higher-ups come to settle accounts with us."

"There are dangers in everything I do. Even in ordinary jobs, accidents may happen and I may fall down while walking on the street. So danger does not stop me from dreaming."

Jiang Chen raised his head and glanced at the beautiful Shangguan Wan'er: "I didn't expect that such a beautiful girl like you would be so yearning for dangerous things."

People in the infirmary initially judged that Li Yapeng might have injured his bones, but it would not be too serious.

After all, laboratories are really short of talent.

Because the head turned and flew past his calf, there was no frontal focus.

Tao Yuan also expressed concern: "Xiao Jiang, as I said before, your safety is more important than anything else."

Everyone is busy at their posts.

When you're done, turn around and leave.

Yang Weimin stood up: "Okay, as long as you're fine, pay attention to safety."

"Yes, of course!" Shangguan Wan'er replied without hesitation:

After the two left, Jiang Chen went to the infirmary again.

"Engaging in research is a very dangerous thing. How about you, are you still interested in joining the laboratory?"

Of course, it’s up to the hospital to make a final decision.

After coming out of the infirmary, Jiang Chen went to the Sangang machine tool production workshop.

Zhou Xinjian nodded to him and continued to pay attention to the production of Sangang machine tools and understand the details of the assembly line model.

Li Yapeng is no longer here and has probably been sent to the hospital for treatment.

Now that Lu Yuehua has been raped, the position of leader of the alloy steel research team is vacant, but no suitable person can be found to replace it.

Cao Jun is loyal enough and has decent abilities, but his management ability is probably only slightly better than Lu Yuehua's, and he still needs to continue to hone his skills.

Shangguan Wan'er was from a prominent family and was a generous person, so she might have potential.

But he didn't want to make a decision easily before he had absolute trust.

What happened this time is a lesson.

Shangguan Wan'er said simply: "I'm not even afraid of losing my life, so how can I be afraid of being disfigured."

"I don't need to live on my face."

Jiang Chen smiled and did not continue the topic: "You come to Sijiu City alone, will your family feel at ease?"

"Have you not considered bringing them all to Sijiu City?"

Shangguan Wan'er shook her head: "My father advocates freedom and yearns to travel among the great rivers and mountains of the motherland, explore the dangerous peaks and mountains, and be intoxicated by the beauty of nature."

"Now, I probably don't even know where to stay!"

Jiang Chen gave the other party a strange look. Do children from this scholarly family speak in such a refined manner, as if they were endorsing something?

Jiang Chen asked: "I've never heard you talk about your partner. Are you not married yet?"

Shangguan Wan'er nodded: "Not yet."

Jiang Chen was startled: "That shouldn't be the case. If you have such good conditions, I'm afraid there will be a long queue of people chasing you. Why haven't you gotten married yet? Don't your family urge you?"

At 22 years old, she can be regarded as an older leftover girl.

It would be strange if the parents didn't urge me. Shangguan Wan'er sighed: "My parents naturally hope that I will find a home early, but so far I have not met a man who can conquer me. I don't want to give in to a life-long event such as marriage."

Jiang Chen smiled and said: "Don't be too picky, otherwise the better you are, the fewer people will be worthy of you. And among those truly outstanding boys, there are very few who are not married at the age of 22."

"In two years, as you get older, it will be harder to find the right person."

He thought about it carefully and found that there was really no man in his circle who could match the girl in front of him.

Shangguan Wan'er said: "Then I will not get married and devote my whole life to scientific research."

Seeing that the other party was speaking firmly, Jiang Chen stopped saying anything.

"1 atmosphere pressure, 99.5% pure oxygen blown in."

After Su Changming gave the order, he turned on the oxygen blowing switch.

99.5% pure oxygen is blown into the mixture of molten iron and charge through the nozzle.

There was a roaring sound in the furnace, but it was much smaller than that accident and was within the normal range.

"Temperature 1400."

"Temperature 1500."

"Temperature 1600."

"Temperature 1650."

"Temperature 1680."

After the oxygen is blown in, the furnace body heats up rapidly.

After that, the temperature basically remained stable around 1700 degrees.

Materials such as molten iron and scrap steel in the furnace quickly transform into molten steel at high temperatures.

After 12 minutes, the temperature began to decrease slowly.

After 15 minutes, the temperature is lower than 1600 degrees and brown steam appears, indicating that the steel has been tempered and the oxygen blowing is stopped.

Then tilt the furnace body to draw out the molten steel.

The red molten steel flows out of the furnace and enters the mold.

As a veteran of steelmaking, Su Changming said excitedly: "Gong Jiang, it's successful, it's successful. I can tell at a glance that what we are smelting should be steel."

After Jiang Chen proposed a reasonable silicon-increasing treatment method, the experiment finally got on track.

The rest is to calculate the amount of silicon added and control the refining process.

As well as the subsequent actual control of temperature control, coolant and slagging materials, etc.

All require multiple experiments to continuously improve and verify.

Steelmaking is not static, but requires different responses based on actual conditions.

When there are correct ways to deal with various situations that may arise, this steelmaking method can be regarded as a successful research.

During the experiment, they also encountered various situations.

For example, the temperature decreases slowly, the calcium silicate powder is added insufficiently or too much, etc. We have found ways to deal with it through experiments.

Fortunately, the converter makes steel quickly and can conduct multiple experiments a day, so the progress is also very fast.

In just four days, they basically found the correct method of making steel and the solution to the main problems.

This furnace of steel is the result of many previous experiments.

And the amount of steel refined this time is 30 tons.

Jiang Chen waved his hand: "Don't be too happy now. Let's wait for the steel to cool down and send it for testing."

"Okay, everyone, thank you for your hard work. Let's go and rest first."

Of course, this test is a basic test.

As long as the hardness, toughness, composition and other aspects are tested, and the testing is done in our own factory, the speed is relatively fast.

Results will usually be available within a few hours.

In the past, when testing, people here would continue with the next experiment.

But this time there is no need, they need to wait for the final results to come out.

Moreover, this time it was made according to the standard top-blown oxygen converter steelmaking mode of the system, so there will definitely be no problems.

There are no flaws other than the flaws of the method itself.

When the test results come out, it is time to modify the converter and study the best steelmaking method that has not yet appeared in the world.
