The oxygen content of special steel is indeed a concept that is difficult to imagine.

For the top special steels, the manufacturing process and process have been extremely demanding, and many steps in the manufacturing process of bearing steel must be carried out in a vacuum, and the interference caused by air must be eliminated.

A small flaw in any one of these operations can have a huge impact.

Even if there are no flaws in the manufacturing process, the requirements for the process and process have reached the peak, and the oxygen content can only be increased to 5pp in the end

The current 4pp is no longer conceivable, and it can be said that it has reached the limit of the conventional.

At present, none of the world's top technologies have been able to break through this limit.

Bearing steels with a 4pp oxygen content can support the largest, most accurate and most demanding bearings.

If you want to break through the highest international level, what is the easy thing to do?

In some fields, it is possible for China to catch up with and surpass the international level of technology.

For example, the software industry.

If a software appears in the world, it can also be quickly developed in China, because the technology involved is not high-end.

High-end material technology is not something you can catch up with.

At present, there is still a huge gap between the domestic high-end materials field and the highest international level, and it is obvious that many high-end materials in China need to rely on imports.

Apparently.

In the field of materials that need to rely on imports, domestic enterprises and scientific research teams have also invested in research and development, and some materials will also be reverse-engineered, hoping to imitate and manufacture, but most of the research has no progress at all in a short period of time.

This is mainly due to the overall disparity.

First of all, some of the world's top material companies have a history of 100 years in material research, and they have accumulated countless experience in the 100-year history.

At the same time, they also have market support.

With the support of the international market, it is possible to make the product profitable, and then continue to invest in research and development, forming a mutually reinforcing cycle.

Many companies that have mastered the highest manufacturing technology in the field of materials, the R&D expenditure, the scientific research energy invested and the R&D time are very impressive.

Obviously, these are not things that can be achieved or surpassed in a short period of time and with some financial investment.

The domestic field of high-end materials is facing such a problem.

The same is true in the field of high-end bearing steels.

The world's top companies spend decades, invest a lot of scientific research energy and research and development funds, master the top bearing steel manufacturing technology, just rely on one or a few teams, plus a certain amount of financial support, want to catch up or surpass, how is it possible?

Even if the manufacturing technology is just catching up, it's already remarkable.

Transcend?

Peng Hui must not dare to think about it.

If you really go beyond it, you won't have any reference, and you won't even have a concept in your head.

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 bearing steel produced reached 4pp, and he was a little disappointed to know the news, because it was slightly higher than estimated.

"It's probably a problem with the manufacturing process, right?"

Wang Hao pondered.

But the gap is not so big, and he didn't take it to heart, so he discussed the problem of bearing steel manufacturing with Shi Guifang and others.

Wang Hao divided the discussion into two parts, one of which was about adding rare earth elements.

Adding rare elements in the manufacturing process of special steel can ineffectively increase the toughness of steel, but it does not help to reduce 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, that is, adding one or several new processes in the manufacturing process of special steels to see if they can help reduce the oxygen content.

Wang Hao read a lot of information before, and also thought of several methods, so he discussed with Shi Guifang and others, but the final result was a little regrettable, the discussion meeting lasted for more than two hours, and there was no progress.

"Academician Wang, there are many methods, we have tried them, but nothing has worked."

"We've also demonstrated new approaches, some of which might work, but they're too costly and too demanding for the environment to be implemented in a lab environment."

"I think there's a way to ......."

"However, even if the laboratory environment can be truly manufactured, there will be problems......

Wang Hao identified several methods that would help reduce the oxygen content of steel, but the effect was certainly not so obvious.

"Add one and a few steps in between, as long as there are no counter-effects."

Wang Hao summed it up and said, "After you go back, you can try the method we discussed, and then look at the data."

"We will."

"I'll experiment when I get back!"

Wang Hao was talking to Shi Guifang and others, and suddenly the phone rang again.

By this time, the meeting had ended.

He picked up the phone and glanced at it, and then immediately pressed the answer button, and heard a message from He Yi on the other side, "Academician Wang, the new equipment has been installed, and the experiment can be carried out tomorrow at the earliest."

"Good~~"

Wang Hao was still thinking about reducing the oxygen content of steel, but he didn't react for a while.

After putting down the phone, he remembered what He Yi had said, the new equipment of the Anti-Gravity Research Center was in place and could conduct new experiments.

This experiment was remarkable.

The new equipment they made can create more than 75% of the quadruple superimposed anti-gravity field, which is simply four high-end anti-gravity devices, placed in the form of a square in four directions, so that the anti-gravity field is evenly superimposed together, and a quadruple high-index superimposed force field can be created.

"The superposition force field, that is, the study of strong annihilation, should also be paid attention to......

This is the world's most high-end scientific and technological research.

"Strong annihilation, magnetization, ......"

Wang Hao suddenly frowned when he thought about it.

When the magnetization reaction of the superimposed force field is linked to the problem of the oxygen content of the steel, an idea appears in my mind - the magnetization reaction of the superimposed force field can help the steel continue to reduce the oxygen content.

「！！」

Wang Hao's eyes widened suddenly, excitedly digesting this unexpected joy.

Magnetization at the edge of the superimposed force field?

Steel reduces oxygen content?

"That's right!"

"If you add a process to the manufacturing process just now, no matter what you know by looking at any information, it has already been used!"

"Naturally, those processes can't help!"

"The magnetization effect caused by the strong annihilation force is different, it is the effect of the strong spatial extrusion, and the specific effect is not necessarily there. Now it's just making magnetized ......."

"Magnetization is caused by the interference of strong annihilation forces, which causes electrons to have directional motion......

"Different substances, for the same magnetization effect, the reaction is also completely different, new fields, new methods, there are too many to explore!"

"Maybe we can continue to reduce the oxygen content of steel!"

「……」

After thinking things through, Wang Hao immediately went to the Anti-Gravity Sex Research Center and saw the large-scale equipment that had just been assembled.

He Yi introduced, "Academician Wang, this large device is the one modified last time, and a new anti-gravity device has been added, which is the upside-down one at the top."

"There are other modifications, and the C013 we used has a relatively better effect, creating an anti-gravity field strength of 76.9 points."

"Quadruple superposition, the edge magnetization effect is definitely more obvious."

He said about international cooperation research, "We have reported the data last time, and the three institutions of Amricon, Germany and Ruishi, have also reported data two days ago, and the new data has been updated a lot."

"Now that it's new research, I don't think it's a problem to cooperate, right?"

"Not there."

Wang Hao shook his head and said, "This is our own research, and we will use this device to do a lot of new research." He asked, "By the way, how is the High Energy Institute?" When are they going to install the equipment?"

He's talking about the new lab.

The Anti-Gravity Properties Research Center has applied for a new closed laboratory, which is located in a controlled area 50 kilometers from the city center.

The new laboratory will cooperate with the Institute of High Energy to install equipment that can create a high magnetic field, which will be used to study the directional offset of the high magnetic field to the anti-gravity field, and combined with the high-strength superimposed force field, it may be possible to make some new discoveries.

This is an important part of the study of strong annihilation.

He Yi said, "We have been communicating, they are preparing, probably next month."

Wang Hao nodded lightly, thinking about it, and explained, "In this way, let's not rush to conduct experiments first. I'll get in touch with other departments and coordinate a research team.

"Huh?"

He Yi was very puzzled when he heard it.

Wang Hao didn't explain much, just asked him to continue to prepare for the experiment, and then reported to the Ministry of Science and Technology and the Aviation Group, and asked the Institute of Aeronautical Materials to send a material team over through the Aviation Group, and also bring some high-end equipment.

It's not something that can be done in a few days.

What Wang Hao has to do is very simple, that is, to conduct a more detailed detection of the magnetized metal under the high-strength superimposed force field, so as to understand all the changes in the metal.

In addition, he also wanted to start from the manufacturing process of metal materials such as alloys and steel, and see if he could add the magnetization process at the edge of the superimposed force field to the manufacturing process to find some very effective effects.

This is obviously a large study.

It involves strong annihilation power, and it also involves alloy materials, and the combination of each other is attractive enough.

Aviation Industry Group naturally has a 100% supportive attitude towards Wang Hao's research.

The study of the anti-gravity superposition force field has nothing to do with them, but when it comes to alloy materials, it is the same, and 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 the summary of the meeting, that is, some of Wang Hao's suggestions, and the metal laboratory also added several manufacturing processes to the special steel improvement process according to the suggestions.

A series of experiments took half a month, but the final results were not too ideal, but the data continued to decrease.

At the meeting, Wan Yiming took a detailed report and seriously concluded, "In the past half a month, we have conducted several experiments in a row, and the oxygen content of the special steel produced is 4pp, the lowest data is 3.98pp, and the highest is 4.13."

"After several experiments, we can roughly determine that the oxygen content of the steel can be further reduced by 0.4-0.7pp by several additional processes."

"The effect is still there, but it's ......."

Wan Yiming shook his head as he spoke, "While increasing the process, it has also greatly increased the cost, which is four times or even higher than the original, which is a bit more than worth the loss."

He made a summary from the perspective of Wuhan Iron and Steel.

If it is only from the perspective of scientific research, as long as it can reduce the oxygen content of steel, it will definitely be a research achievement, but from the perspective of Wuhan Iron and Steel, the situation is different.

WISCO is a normal company, and the products manufactured are to be sold in the market.

When a technology improves product performance slightly, but increases manufacturing costs several times, it is obviously very much worth the loss.

Peng Hui nodded after hearing this, and said, "That's it, record the recent research as well, and this can be regarded as a further achievement."

"Prepare for a report."

"Our research is over."

"Where's Academician Wang?" Shi Guifang suddenly asked, "I think what Academician Wang means seems to be that he also wants to increase the toughness of steel."

Peng Hui said, "I will ask Academician Wang in advance to see what you want us to cooperate with."

He thought about it and thought, "Actually, it doesn't have much to do with us, if we reduce the oxygen content or make other improvements in the future, Academician Wang can also go directly to the Wuhan Iron and Steel Research Institute."

"That's all we can do in our lab, for example, the rare earth problem you discussed has nothing to do with us, and we can't solve it.

Wan Yiming suddenly said, "There is one more thing, Academician Wang said, let us send all the finished products made by the experiment to Xihai University."

"Huh? And this thing?"

"yes, I did." Shi Guifang emphasized, "I said it after I came back from the West Sea."

Peng Hui suddenly patted his head hard, "Look at my memory! Okay, but I'll report it to Wuhan Iron and Steel."

"Wuhan Iron and Steel knows that it's Academician Wang, so it's definitely no problem. It's just that Wuhan Iron and Steel sent people to verify the results, and there are too few experimental products, which is not good, right?"

"Academician Wang said that he wanted the finished product of the experiment, and he didn't say that he wouldn't return it, right? We'll wait until we get back and turn in the report?"

"That's fine."

A few people have concluded their deliberations.

Wan Yiming thought about it and suddenly asked, "You say, why did Academician Wang let us send the finished experimental product over?" Isn't he still looking for a way to keep his oxygen levels lower?"

"This ......"

"Probably, right?"

"Could it be that his goal is really 3pp" Wan Yiming's expression was a little exaggerated, "This data feels unreliable!"

"I guess."

Peng Hui thought about it and said, "Academician Wang just wants to test it, maybe it is to do some data comparison, or summarize something......

"Anyway, Academician Wang, it's not something we can imagine."
