The oxygen content of 3pp in special steel is indeed a concept that is difficult to imagine.
For top-notch special steels, the manufacturing technology and processes are extremely demanding. During the manufacturing process of bearing steel, many steps must be performed in a vacuum, and interference caused by air must be eliminated.
Any small flaw in the operation process will have a huge impact.
Even if there are no flaws in the manufacturing process, the requirements for technology and processes have reached their peak, and in the end the oxygen content can only be increased to 5pp.
The current 4pp is no longer imaginable, and it can be said to have reached the conventional limit.
At present, the world's highest technologies have not been able to break through this limit.
Bearing steel with 4pp oxygen content can already support the largest bearings with the highest precision and the most stringent requirements.
How easy is it to break through to the highest international level?
In some fields of technology, it is possible for China to catch up with and surpass the international level.
For example, the software industry.
If a piece of software appears internationally, it can be quickly developed in China as a reference because the technology involved is not high-end.
High-end material technology is not something you can catch up just by trying to catch up.
At present, there is still a huge gap between the domestic high-end materials field and the highest international level. It is obvious that many domestic high-end materials need to rely on imports.
Obviously.
In the field of materials that rely on imports, domestic companies and scientific research teams have also invested in research and development. Some materials will also be reverse-engineered in the hope that they can be imitated and manufactured. However, most of the research has made no progress at all in a short period of time.
This mainly lies in the overall gap.
First of all, some of the world's top materials companies have a century-old history in materials research, and they have accumulated countless experiences during their century-long history.
At the same time, they also have market support.
With the support of the international market, products can be manufactured to generate profits, and then they can be continuously invested in research and development, forming a mutually reinforcing cycle.
For many companies that have mastered the highest manufacturing technology in the field of materials, their R&D funding, scientific research energy, and R&D time are all amazing.
These are obviously not something that can be achieved or surpassed in a short time and with some financial investment.
The domestic high-end materials field is facing this kind of problem.
The same is true in the field of high-end bearing steel.
The top international companies have spent decades, invested a lot of scientific research energy and R&D funds, and mastered the top bearing steel manufacturing technology. They just rely on one or a few teams, coupled with the support of a certain amount of funds, to catch up or surpass them. How is it possible?
Even if the manufacturing technology is just catching up, it is already remarkable.
Beyond?
Peng Hui would definitely not dare to think about it.
If you truly transcend, you will no longer have any reference, and there will really be no concept in your mind.
the other side.
Wang Hao didn't have so many ideas.
After Peng Hui's team improved the manufacturing process and process, the oxygen content of the produced bearing steel reached 4pp. He was a little disappointed when he heard the news, because it was slightly higher than expected.
"It must be a problem with the manufacturing process, right?"
Wang Hao thought.
But the gap was not that big, so he didn't take it to heart, so he discussed the issue of bearing steel manufacturing with Shi Guifang and others.
Wang Hao divided the discussion into two parts. One part is about adding rare earth elements.
Adding rare elements during the manufacturing process of special steel can effectively increase the toughness of the steel, but it is not helpful in reducing the oxygen content.
In this part of the discussion, Wang Hao mainly hopes to increase his understanding of bearing steel manufacturing.
The other part is directly related, which is to add one or several new processes in the manufacturing process of special steel to see if it can help reduce the oxygen content.
Before, Wang Hao read a lot of information and thought of several methods, so he discussed it with Shi Guifang and others. However, the final result was a bit regretful. The discussion meeting lasted for more than two hours without any progress.
"Academician Wang, there are many methods. We have tried them all, but they have no effect."
"We have also demonstrated the use of new methods. Some methods may be effective, but the cost is too high, and the environmental requirements are too harsh, and they cannot be implemented in a laboratory environment."
"I think there is a way..."
"However, even if the laboratory environment can achieve real manufacturing, problems may arise later..."
The entire discussion meeting was fruitful. Wang Hao identified several methods that would be helpful in reducing the oxygen content of steel, but the effect was definitely not that obvious.
"Add one or more steps in the middle, as long as there are no counter-effects."
Wang Hao summed it up and said, "When you go back, you can try the method we discussed and look at the data then."
"We will."
"Let's experiment when we get back!"
Wang Haozheng was talking to Shi Guifang and others when suddenly the phone rang again.
By this time, the meeting had ended.
He picked up the phone and took a look, and then immediately pressed the answer button. He heard a message from He Yi on the opposite side, "Academician Wang, the new equipment has been installed, and experiments can be carried out as soon as tomorrow."
"Okay~~"
Wang Hao was still thinking about reducing the oxygen content of the steel, but he didn't react for a while.
After he put down the phone, he remembered exactly what He Yi was talking about. The new equipment at the Anti-Gravity Research Center was in place and new experiments could be conducted.
This experiment was remarkable.
The new equipment they manufactured can create more than 75% of the four-overlapping anti-gravity field. Simply put, it is four high-end anti-gravity equipment placed in a square shape in four directions to make the anti-gravity field uniform. Stacked together, four high-index superimposed force fields can be created.
"You should also pay attention to the research on superimposed force fields, that is, strong annihilation forces..."
This is the most advanced scientific and technological research in the world.
"Strong annihilation power, magnetization..."
Wang Hao suddenly frowned while thinking.
When the magnetization reaction of the superimposed force field was related to the oxygen content of steel, an idea came to mind - the magnetization reaction of the superimposed force field can help the steel continue to reduce the oxygen content.
"!!"
Wang Hao's eyes widened immediately, digesting this unexpected surprise with excitement.
Edge magnetization effect of superimposed force field?
Steel reduces oxygen content?
"yes!"
"If you were to add a process to the manufacturing process just now, no matter what process you know from any data, it has already been used by others!"
"Of course those processes can't help!"
"The magnetization effect caused by strong annihilation force is different. It is the effect caused by strong space compression. The specific effect is not necessarily certain. Now it is just creating magnetization..."
"Magnetization is due to the interference of strong annihilation force, which causes electrons to have directional movement..."
"Different substances have completely different reactions to the same magnetization effect. There are so many new fields and new methods to explore!"
"Perhaps we can continue to reduce the oxygen content of steel!"
"..."
After figuring things out, Wang Hao immediately went to the Antigravity Behavior Research Center and saw the large equipment that had just been assembled.
He Yi introduced, "Academician Wang, this large equipment is modified from the last one. A new anti-gravity device is added, which is the inverted one at the top."
"Other modifications have also been made. The C013 we used has a relatively better effect. The anti-gravity field strength produced reached 76.9 points."
"When four stacks are added, the edge magnetization effect is definitely more obvious."
He talked about international cooperative research, "Our last data has been reported. American's three institutions, Germany and Swiss, also reported data in the past two days, and the new data has been updated a lot."
"Now that there is new research, there should be no worries about cooperation, right?"
"Not here."
Wang Hao shook his head and said, "This is our own research. We are going to use this device to do a lot of new research." He asked, "By the way, what about the Institute of High Energy? When will they come to install the equipment?"
He was talking about the new laboratory.
The Antigravity Behavior Research Center applied for a new closed laboratory in a control area fifty kilometers away from the city center.
The new laboratory will cooperate with the Institute of High Energy to install equipment that can create high magnetic fields to study the directional deflection of high magnetic fields to antigravity fields. Combined with high-intensity superimposed force fields, new discoveries may be made.
This is an important part of the study of strong annihilation forces.
He Yidao, "We have been communicating, and they are preparing, probably next month."
Wang Hao nodded slightly, and said after thinking, "In this way, we are not in a hurry to conduct experiments. I will contact other departments and coordinate a research team.
"ah?"
He Yi was very puzzled after hearing this.
Wang Hao didn't explain much and just asked him to continue preparing for the experiment. Then he sent reports to the Ministry of Science and Technology and the Aviation Group, and through the Aviation Group, he asked the Aviation Materials Institute to send a materials team and bring some high-end equipment.
This cannot be accomplished in a few days.
What Wang Hao wants to do is very simple, that is, to conduct more detailed inspections of magnetized metals under high-intensity superimposed force fields in order to understand all changes in the metals.
In addition, he also wants to start from the manufacturing process of metal materials such as alloys and steels to see if the superimposed force field edge magnetization process can be added to the manufacturing process to discover some very effective effects.
This is obviously a large study.
It involves strong annihilation force and alloy materials. The combination of them is attractive enough.
The Aviation Industry Group naturally supports Wang Hao's research 100%.
The research on anti-gravity superimposed force fields has nothing to do with them, but it does involve alloy materials. No matter how much it costs, a team must be sent to support it.
…
Shi Guifang, Lou Jianping and others have returned to the metal laboratory of Xijing Jiaotong University.
What they brought back was a summary of the meeting, which was some of Wang Hao's suggestions. Based on the suggestions, the Metal Laboratory added several manufacturing processes to the special steel improvement process.
A series of experiments took half a month, but the final results were not ideal, but the data continued to decrease.
At the meeting, Wan Yiming took a detailed report and carefully concluded, "In the past half month, we have conducted several experiments in a row, and the oxygen content of the special steel produced is around 4pp, with the lowest data being 3.98pp and the highest is 4.13.”
"Through several experiments, we can roughly determine several additional processes that can further reduce the oxygen content of steel by about 0.4-0.7pp."
"The effect is still there, but..."
Wan Yiming still shook his head as he spoke, "While increasing the process, it also greatly increased the cost, four times or more than the original increase. It's a bit outweighing the gain."
He concluded from the perspective of Wuhan Iron and Steel Co., Ltd.
From the perspective of scientific research, as long as the oxygen content of steel can be reduced, it will definitely be a research result, but from the perspective of Wuhan Iron and Steel, the situation is different.
Wuhan Iron and Steel is a company operating normally, and the products it manufactures must be sold on the market.
When a technology makes a small improvement in product performance, but increases manufacturing costs several times, it is obviously not worth the gain.
Peng Hui nodded and said, "That's it. Record the recent research. This can be considered a further achievement."
"Get ready to report."
"Our research has ended."
"Where's Academician Wang?" Shi Guifang suddenly asked, "I think what Academician Wang means is that he wants to increase the toughness of the steel."
Peng Hui said, "I will ask Academician Wang in advance to see what we need to cooperate with."
He thought for a while and then thought, "Actually, it has little to do with us. If the oxygen content is lowered or other improvements are made in the future, Academician Wang can also directly contact the Wuhan Iron and Steel Research Institute."
"This is all our laboratory can do. For example, the rare earth issue you are discussing has nothing to do with us and cannot be solved by us.
Wan Yiming suddenly said, "One more thing, Academician Wang said, let us send all the finished products produced by the experiment to Xihai University."
"Huh? Is there still such a thing?"
"Yes, I said it." Shi Guifang emphasized, "I said it after I came back from the West Sea."
Peng Hui suddenly slapped his head hard, "Look at my memory! Okay, but I have to report it to Wuhan Iron and Steel."
"Wugang knows that it's Academician Wang, so there must be no problem. It's just that Wuhan sent people to verify the results, and there are too few experimental products. Isn't that okay?"
"Academician Wang said he wanted the finished product of the experiment, but he didn't say he wouldn't return it, right? We just wait until it's returned and then submit the report?"
"That's okay too."
Several people concluded the discussion.
Wan Yiming was thinking and suddenly asked, "Tell me, why did Academician Wang ask us to send the finished experimental product? Isn't he still trying to find a way to continue to reduce the oxygen content?"
"this……"
"may be?"
"Could it be that his goal is really 3pp?" Wan Yiming's expression was a little exaggerated. "This data seems unreliable!"
"I guess so."
Peng Hui thought about it and said, "Academician Wang just wants to test it, maybe for data comparison or summary..."
"Anyway, Academician Wang, it's not something we can imagine."
