reborn industrial empire

Chapter 440: Breaking Technical Barriers

Nearly twenty chapters have been written in three days, and I am almost exhausted and vomiting blood. Please help the ants more!

"In order to solve the problem of the internal stress of this machine frame, I read a large number of journals and scientific magazines. I even dug out the information from decades ago and re-read it. It is not that there are no corresponding ones in China at present.

The solution is the method adopted by Nanyang Machine Chuáng and Dalian Machine Chuáng Factory.

It is natural aging, but this method is too old, the cycle is too long, and it takes up space and money. There are many international solutions, such as thermal aging and vibration aging, which can eliminate the internal damage of the machine parts.

The problem of stress, but the foreign devils have kept these processing methods and processing tools too close, and they have never been available in China. At present, Nanyang Machinery

Huáng and Dalian Jichuáng are also talking with the Germans and Japanese respectively to see if they can get some molding technology and machinery from them. But the situation is not good. The Japanese and Germans regard these technologies as

The vibrator used for vibration aging is a little better. We also introduced some earlier, although it is relatively

It's backward, but it can still be used, but these guys just want to keep a close eye on the thermal aging process. It is estimated that even if it is finally introduced, it will be the same as before, and it will cost a lot of money, and it can only be done

I got outdated technology that others didn’t want, so after thinking about it, I just gritted my teeth and did it ourselves..."

Zhang Hainan explained to Jin Xiaoqiang while taking Jin Xiaoqiang around their research institute.

"Yes, if they don't give it to us, we will do it ourselves. I don't believe it. We are already in the Internet age, the age of the explosion of knowledge. How can they still keep those secrets so tightly sealed? As long as we can get some of their research and development

We should be able to copy the information."

Jin Xiaoqiang also nodded, agreeing with Zhang Hainan's theory. Selling technology from foreigners is indeed unreliable. It has been so many years, and the technology bought from these foreign devils is...

Isn't it the obsolete technology that others use?

Once these technologies are adopted, we will always have to follow in the footsteps of these foreign devils. This is definitely not what Jin Xiaoqiang wants to see.

When Zhang Hainan heard Jin Xiaoqiang's supportive attitude, he nodded secretly. With such a boss, he was indeed with the wrong person.

"For more than a year, we have been working hard to eliminate the internal stress of machine parts. We have basically mastered the thermal aging and vibration aging processes, as well as some conventional methods of manufacturing mechanical parts."

Zhang Hainan told Jin Xiaoqiang the results of their hard work this year, and Jin Xiaoqiang immediately burst into laughter.

"Hurry up and tell me."

"As for the solution to thermal aging, I consulted a lot of information at that time, and later did a lot of related experiments, and then I found out that thermal aging is actually mainly used for welding parts and castings required for machine frames.

The method adopted is to keep these workpieces in a temperature range of 500 degrees to 650 degrees for 6 to 8 hours until the furnace temperature slowly drops.

When the temperature reaches 150 degrees, airborne cooling is the only way out. Moreover, this thermal aging process should be placed after mechanical rough machining, so that the internal stress involved in casting or welding and the residual stress caused by rough machining can be eliminated and homogenized.

.However, for high-precision machined parts, the second thermal aging can be arranged after semi-precision machining. All surfaces, holes, and grooves with large machining volume should be processed before the first thermal aging.”

Zhang Hainan explained it to Jin Xiaoqiang, and Jin Xiaoqiang nodded frequently. In fact, he didn't fully understand these things. For machines, he really didn't know as much as lithium batteries, which are closely related to cars.

But this does not hinder his desire and attention for high-precision machinery, because he knows that compared with automobile manufacturing, the manufacturing of this machinery is the key.

Because it is the production of these machines that can ensure that his Huayang Power can create better cars.

Moreover, this thermal aging method can not only be applied to machine parts, but also the high-end luxury cars and even supercar parts they need to manufacture in the future will also require such heat treatment technology.

This kind of heat treatment technology is what domestic steel plants currently lack most.

This is also thanks to his previous acquisition of so many special metal smelting materials and technologies from Shinyuki Naruto, and also secretly imported a lot of small smelting and forging equipment from Japan.

After several years of training, He Naruto Shinyuki has come to Nanyang many times to provide guidance to the technical staff of his special steel smelting company. These smelting and forging equipment have been given to him by the technical staff of his special steel smelting department.

He understood it thoroughly and built several large-scale equipment.

Otherwise, even if Zhang Hainan has ideas, it may be difficult to put these technologies into practice. And even though he sounds relaxed now, in fact, when he was exploring such heat treatment methods, he didn't know

How many experiments have been done and how many detours have been taken.

For such technology, one has to be willing to spend money. Fortunately, he has now formed a small industrial chain of a certain scale. For example, metal raw materials can be obtained directly from his father, special steel smelting facilities, and steel plants.

I have it, otherwise I would have to spend dozens or tens of billions just to solve such a heat treatment experiment to eliminate internal stress.

This is also thanks to the fact that he is taller than others. If it were anyone else, it would really be impossible. But even so, Zhang Hainan and the others spent no less than 500 million on experiments just to solve the problem of internal stress.

"For example, when manufacturing the chuáng body of a milling chuangg, when using HT300 steel, the heat treatment temperature range must be controlled between 550 degrees and 570 degrees, while the part using HT200 steel must be controlled between 520 and 550 degrees.

Between degrees, the insulation is 6 hours. The welded structure of the bed beam steel plate is used

Q235 must be kept at 620 degrees to 650 degrees and kept warm for 4 hours. Hahaha, we had to be divided into more than a dozen groups every day, and each group stared at several furnaces. All experiments were carried out at the same time, and everyone worked day and night.

After working for more than three months, I basically figured out these processes and processes. By the time the experiments were completed, everyone was so tired that they were out of shape..."

Zhang Hainan told about the pain and joy of their work, but at this time, his face showed more excitement. Obviously, that time was one of the best and happiest times in his life, because they

I have taken the first solid step on the road to my current ideal.

But what Jin Xiaoqiang saw was only moved, and at the same time, what he was thinking in his heart was whether it was time to increase their wages...

"However, this thermal aging method and process is not omnipotent. It also has shortcomings, that is, high equipment investment, long production cycle, and high energy consumption. The most important thing is that these processes are not suitable for the production of guide rails and other

special parts."

Zhang Hainan explained to Jin Xiaoqiang.

"It doesn't matter, Mr. Zhang is not afraid. We at Huayang Dynamics have never been afraid of spending money on research and development. You can just work hard and try to develop a full set of technologies for me."

Jin Xiaoqiang is full of pride at this time. He is really not afraid to throw money into it now. Huayang Power's current models are selling well. It can be said that the car company is making money every day, and the Thunderbird in the United States is even more popular.

Gain a lot by cutting through the wind in the stock market.

And the most important thing is that these companies are all his own. They are not listed on the market, and he does not need to be responsible to shareholders. As long as he can pay employees enough wages and ensure the normal operation of the company, he is willing to use the remaining money

Wherever you go, you go.

These processes may seem like nothing, but from now on if there is one thing that I cannot do, I will have to be pinched by outsiders. People with his strengths don't like to live by being pinched by others.

What's more, these processes are all laying the foundation for his future equipment manufacturing industry. Only by mastering these can he consolidate the cornerstone of his future industrial empire.

"As for the vibration aging method, it is relatively simple. As long as you can obtain a suitable vibrator with the same frequency, we have introduced such a vibrator before, but it is relatively backward. This method of eliminating internal stress

In fact, the principle is very simple, that is, fix the workpiece on the vibrating table, and then use the vibrator to firmly install it at the peak of the vibration of the workpiece. The workpiece resonates under the action of the periodic external force exerted by the vibrator, and the workpiece

,chuá

The deformation stress experienced by each part of the ng body is superimposed with the residual internal stress inside, causing local yielding of the workpiece, causing slight plastic deformation, causing the residual stress to relax or stabilize or redistribute, tend to be uniform, and strengthen the metal matrix.

The anti-deformation ability achieves the purpose of improving the precision and stability of the workpiece assembly. This process is mainly used for non-alloy structural steel, low carbon alloy structural steel, stainless steel, various cast iron and non-metal basic parts, welded components and other components."

Zhang Hainan began to explain the vibration aging method to Jin Xiaoqiang again, and Jin Xiaoqiang also listened attentively. At this time, Zhang Hainan became more and more excited as he talked. It seemed that he had reached the part he was most proud of...

“However, the most advanced vibration aging technology at present is spectrum harmonic vibration aging technology. This technology analyzes the spectrum of the workpiece to find dozens of harmonic frequencies, and selects the five best ones for eliminating residual stress in the workpiece.

Aging treatment is performed on the harmonic bo frequencies of different modes of vibration to achieve multi-dimensional stress relief and improve dimensional stability. This is our most critical technology to overcome...
