Chapter 286 Methods of increasing silicon in converter steelmaking
Jiang Chen took a deep breath, calmed down his mood, and softened his tone:
"Fortunately, no one was killed. Let's end it here! Only by discovering and solving problems can we make progress. Next, let's discuss the reasons for this situation."

"How do you perform siliconization?"

Now that the punishment has been done and Lu Yuehua has made his choice, there is no need for him to hold on to him.

Unless he doesn't want to keep Lu Yuehua.

Lu Yuehua said: "Just sprinkle the calcium silicate powder evenly into the furnace material, and then add it into the furnace body."

Jiang Chen sighed: "Tell me, Teacher Lu, as a chemist, do you know that the calcium silicate powder contained in the dust has a large contact area and a very fast reaction speed, which can easily cause the risk of explosion?"

"Furthermore, if calcium silicate powder is added directly to the furnace charge, the release will be very fast and violent, with a high risk of explosion. It will also react too fast and cannot continuously provide heat."

"So, the way you add silicon is fundamentally wrong."

When Jiang Chen was in a hurry to leave, he just asked Lu Yuehua to calculate the data as a reference, and did not have time to explain in detail how to increase silicon.

And if you think about it for a moment, you will know that it is unreasonable to add calcium silicate powder directly to the furnace charge.

As long as the other party has gained his trust, he will be directly responsible for laboratory matters.

"When conducting research, every step must be carefully considered and chosen, and experiments must be conducted under safe conditions."

"Check carefully to see if it should be repaired or replaced. If the hidden dangers can be eliminated, we will continue the test tomorrow."

Therefore, he directly took back Lu Yuehua's identity as team leader and temporarily took charge of it himself.

"Of course, the disadvantage is that the first one is not adjustable, and the second one is more troublesome. It requires changing the furnace structure and adding a new spray gun."

"But let's not do the experiment today. Later, we will carefully check the damage to the converter, whether the fireproof bricks are damaged, and whether other equipment has been affected."

Jiang Chen waved his hand: "This is science. Even the calculated data can only be used as a basic reference, not to mention your so-called I thought that this is something that must never appear."

Su Changming said, "Then let's try the first option first, and then decide whether to change the furnace structure based on the actual situation."

However, as the subsequent experimental groups increased, there was not enough daughter-in-law.

Lu Yuehua said: "What does Director Jiang mean, how should we carry out the silicon-increasing treatment?"

He used to trust people too much.

"The second is to use a spray gun to spray calcium silicate powder into the bottom of the molten iron during the reaction, as long as it is completely melted before it floats."

"Also, next time, no experiments in converter steelmaking are allowed without the prior consent."

"One is to add calcium silicate powder to the molten iron before it is mixed into the furnace. We can lay calcium silicate powder at the bottom of the container. The vortex caused when the molten iron is injected will stir the calcium silicate powder into the molten iron. in, and melted.”

Jiang Chen said: "As for silicon addition, after careful consideration, I have two ideas. Let's discuss it together."

The grasp of human nature needs to be strengthened, Jiang Chen secretly warned himself.

Jiang Chen nodded: "I also think the first one is more reliable."

But after this incident, he needs to strengthen the management of the laboratory and keep all the core things in his own hands, or in the hands of his wife.

"Of these two methods, the first one has the advantage of being simple and easy to operate, while the second one is adjustable."

Lu Yuehua said: "I know, but I thought that 80% pure oxygen and their reaction speed would be within our control."

He didn't expect Lu Yuehua to be so anxious and reckless.

At this step, the method of adding calcium silicate powder has been determined. What remains is the proportion of calcium silicate powder and the control of pure oxygen concentration.

As long as you continue to experiment, you will always find the most reasonable production parameters and production methods.

There is no room for carelessness in the converter at this experimental stage.

Although he was in control of the overall situation, the construction of the converter and the experiments were all done together, and he could not guarantee that accidents would not happen again.

Everyone nodded.

After this lesson, it is estimated that no one will dare to make claims again. Jiang Chen said to Lu Yuehua: "Go to the infirmary first to check on Comrade Li Yapeng's condition. If the infirmary is not there, go directly to the hospital."

Lu Yuehua nodded: "Okay."

Of course, you must try your best to make up for the trouble you caused.

When Lu Yuehua left, Jiang Chen turned around and threw a cigarette to Su Changming: "Tell me, you are usually so steady, why do you follow Lu Yuehua into chaos?"

Su Changming scratched his head: "Teacher Lu used to be quite prudent in his work. He also calculated the data and conducted experiments based on this data."

"In addition, he is the team leader and the leader, so he asked for the experiment and I cooperated."

Jiang Chen said: "He is so steady. He has always been impetuous in doing things. In the past, I was always keeping an eye on him until the experiment was on track, so nothing happened."

"Besides, he was only the leader of the alloy steel research team before and had nothing to do with this converter steelmaking research."

Su Changming nodded and said nothing.

Jiang Chen patted him on the shoulder: "Okay, unless I authorize it, the experiments here will be subject to my instructions."

Su Changming said: "Okay, Director Jiang."

Jiang Chen stood up, and Xiao Zhou said to the workers who were still frightened around him:
"Okay, don't be so frustrated! As pioneers in the industry, we study areas that others have never touched. Everything is unknown, and accidents are inevitable."

"So in future work, we need to be more rigorous and careful, and strive to eliminate all safety hazards and minimize risks."

"Although this experiment was dangerous, it proved that calcium silicate powder can indeed increase temperature. It once again verified that our direction is correct. We are one step closer to the success of our research."

"Okay, everyone, cheer up, check the damage to the converter, and repair it as soon as possible. Only by researching what we need as soon as possible can we be worthy of Comrade Li Yapeng's sacrifice and dedication."

After Jiang Chen finished speaking, everyone's mood was a little higher, not as lifeless as before.

Su Changming stepped forward and waved: "Okay, let's start!"

"Pay attention to safety, report and communicate the situation first, and make sure there are no hidden dangers before repairing it."

Seeing that everyone had started working, Jiang Chen turned around and walked towards Liu Yu and Jiang Xin who had been watching, and asked, "I have been watching for a day, what do you think?"

Liu Yu said slowly: "I always thought that doing research was a very easy and safe thing. I just played with bottles and jars in the office and operated the instruments and that was it."

"Now I know that doing research is such a dangerous thing."

Jiang Chen smiled slightly: "So, don't take anything for granted. It is often wrong to think that this is what you think."

"We are all good people here, and many of them are engaged in research. They really don't care about life and death. They know that they will escape death, but they still devote themselves to it without hesitation."

These two guys worked hard for a week last week. It was painful and tiring, but they still persisted silently.

Although Jiang Chen scolded them all the ugly words when he was carrying them, he didn't stop, so Jiang Chen didn't speak to them as seriously as he did at the beginning.

Liu Yu was stunned: "Is there really such a dangerous research?"

Jiang Chen said lightly: "Yes!"

He looked to the west, where research on the real national treasure had already begun.

Liu Yu said: "Is it really necessary to continue such a dangerous research?"

Jiang Chen nodded: "Yes, I know it's dangerous but I still have to study it. It must be something very, very important."

"Just like this converter steelmaking, we know that there are risks, but we still have to carry out experiments, because once it is successfully developed, it can increase our steel production many times, which is very important."

"We don't encourage sacrifice, but many things require sacrifice and are worth sacrificing for."

After saying that, Jiang Chen turned and left.

I don’t know if these two people understood it, and how much they could understand.
