ps: Let’s talk about something here while there is still a little free word count in this chapter.

Old readers who are familiar with the author know that the author is a broken hand, and the original little miserable manuscript will be exhausted in a few days. In addition, this is a realistic science and technology novel. In order to write a good technical project, you have to check a lot of information and understand it in a quick way. At least you won’t make low-level mistakes. This item will take several hours. At the same time, you have to find interesting highlights that readers feel in the boring technical information, which is quite laborious. Sometimes, the outline preparation information will occur, and it is found that it is not suitable for the current progress. It must be overturned and started again.

So although the author also wants to speed up the pace, three or five chapters a day to make everyone feel happy, the writing progress is really not fast. He can only write and post as soon as he writes, the update time is not fixed sooner or later, and the amount is sometimes too high and sometimes less. Here, I can only apologize to everyone with shame and hope to be able to understand.

...

While no one was paying attention, Sun Yaohua leaned into Guan Fei's ear and whispered in a mosquito-like voice: "This is the refining furnace you mentioned? With it, can we build our own artillery?"

"Of course there is no problem!" Guan Feihui answered with affirmative answer and added, "Producing high-quality gun steel is only one of them. More importantly, with it, we can smelve very good bearing steel, spring steel, tool steel, and various high-quality special alloys."

"Is that so? Why do I think it's more exciting to produce cannon steel?" Sun Yaohua blinked and laughed embarrassedly.

He understood that bearing steel and other things must be good things. But for him who have fought for many years, those things are too far away from him and have no practical concept. He has not yet refined high-quality steel for making gun barrels, which makes him feel even more grand.

Guan Fei gave him a blank look, helpless.

For those who don’t understand, no matter how they explain it, it will be useless. Compared with being able to refine cannon steel, vacuum electroslag remelting furnaces play an irreplaceable and important role in improving precision manufacturing technology.

Cannon steel and other things can also be smelted with an arc furnace, and the mass production capacity is several times that of a vacuum electroslag remelting furnace, so qualified gun barrels can be produced in large quantities.

However, the physical characteristics of the same smelted steel ingots are more than ten times that of the arc furnace! Compared with ordinary electroslag remelting furnaces without vacuum sealing, the quality is several times higher!

This means that the steel ingots refined with vacuum electroslag remelting furnaces, the gyroscopes, bearing balls, lathe guide rails, lathe tools made are smoother on the surface, higher accuracy, impact-resistant and wear-resistant characteristics, and service life are two to several times that of other similar products. The special alloy ingots refined with vacuum electroslag remelting, the vacuum pressure-resistant shells, engine combustion chambers, and aircraft load-bearing beams are also much higher than those of the same type of special alloys!

Its importance is immeasurable!

In this era, it is a country's important weapon!

If it weren't for the fact that China had roughly mastered the manufacturing technology of electroslag remelting furnaces, this equipment would have been popularized in special alloy factories across the country. However, due to theoretical support, experimental data, and lack of machining, the quality of the ingot is indeed better than that of alloys produced by other refining methods, but it has not yet reached a stunning level. For China, the real potential of this technology has not yet been realized, and it can only be said that the prospects are promising.

Therefore, the country attaches great importance to this technology, but has not yet taken it as a treasure.

Of course, it would be too naive to say that the country is not guarding against military sub-districts at all and give whatever they want.

If it weren't for the foreign exchange in the hands of the military sub-district, the upgraded vacuum electric slag remelting furnace technology provided by Guan Fei was also very attractive to the country, and he was eager to know whether his improvement was effective. However, because Guan Fei provided manufacturing drawings but did not give the main control program, he could not do it secretly. In addition, the country is now swaying back and forth between left and right, and is still quite sympathetic to the brotherly party. The military sub-district is now booming and has a higher position in the hearts of the domestic senior management. With the combined action of various forces, he has taken the attitude of keeping his promises and delivered the produced parts to the military sub-district as scheduled.

But at the same time, in the name of assisting in installation and testing, a large number of experts in metallurgy, machinery and automation were sent, and they wanted to actually examine the improvement of the refining capacity of the improved vacuum electric slag remelting furnace through the practical grasp of the test data.

If it is better than the one developed by China, of course you have to ask Guan Fei for it. If it is not as good as China, of course there is no need to worry about it. Even if some cannon steel can be refined, the quantity will not be too large. With the current processing level of the military sub-district, it can only be manufactured in small quantities, and the impact is not great.

If it weren't for this kind of thinking, the country would never have handed over such advanced equipment to the military sub-district.

In fact, Guan Fei was not sure that this vacuum electric slag remelting furnace would be built for the military sub-district. To be on the safe side, he specially reserved one hand and prepared to exchange for a second-rate arc furnace and continuous casting equipment. He was to slowly upgrade and after he had the corresponding capabilities, he would create a vacuum electric slag remelting furnace or other more suitable refining equipment by himself.

When He Tao, the director of the 5**92 unit who was responsible for contacting the military sub-district, informed him that the equipment had been installed on the road and was about to be sent to the military sub-district, he was so happy that he almost jumped up. With an emotional excitement, he ran to Zhang Shengguo. Sun Yaohua boasted a few words in front of him, and said excitedly, "With this set of equipment, the precision manufacturing capability of the military sub-district is equivalent to improving for ten years at once." This bold statement aroused the strong curiosity of the two. It was rare to put down the busy work in his hands and come to watch with him.

Even now, after experiencing so many things and having already trained to be steady, he still smiles unconsciously. His eyes at the device were as gentle as looking at his beloved girl.

Good stuff, what a good stuff!

It is hard to be so generous in China and bring him such good things.

But it's no wonder.

Although I have been studying it for more than ten years, I have not yet understood this technology in China, and of course I don’t realize how important it is.

Moreover, just having such a set of refining equipment is nothing.

It is like an excellent tool. With it, it can only be said that the physical properties of refined alloys are better than those of the same formula. However, to fully exert its capabilities, excellent technical operators, scientific operating procedures, and precise control of technology.

The most important thing is to require huge experimental data to support it, and to have an in-depth understanding of various metal smelting and processing characteristics. We must master massive alloy formulas and key smelting technologies.

Even in China, there are not many of these things. Otherwise, why are the ingots produced in China using electric slag remelting furnaces with higher sulfur content than those of the Soviet Union, and their strength, wear resistance and lifespan are not as good as those of the Soviet Union?

That's the difference in data!

Without countless experimental investments, there will be no corresponding data support, and it will be impossible to have tens of thousands of material formulas that allow producers to easily smel out special alloys that meet the requirements according to product requirements to meet the needs of manufacturers.

Obviously, the military sub-district is regarded as such a user in China. It just thinks that the vacuum electric slag re-melting furnace is good, but I don’t know that there are so many subsequent requirements and are so strict, and I am not optimistic about its use prospects. In China, instead of having a flashy vacuum electric slag re-melting furnace, the military sub-district is better than a poorer technology for entering the set, but the requirements are lower and the output of the arc furnace is more realistic.

Guan Fei looked at the group of domestic experts who were frenzy around him and couldn't help but run up to help with the installation, and couldn't help but bend the corners of his mouth again.

The installation of vacuum electroslag remelting furnace is time-consuming.

The installation of a vacuum electroslag remelting furnace is a particularly precise project, but the vertical error of the upper and lower parts of the supporting columns of a factory of more than ten meters shall not be greater than one millimeter of zero point. After the support column is established, the vertex gap and horizontal error between each column must also be guaranteed to be within two millimeters of zero point.

Before installation, in order to ensure that each component is processed and meet the requirements, the military sub-district also needs to repeatedly measure each component. To this end, Guan Fei specially selected a large number of elite soldiers and generals from each factory to bring a large number of precision measurement equipment to ensure that this set of equipment will not have any problems.

This makes the entire installation progress never faster. It is a kind of expert who assists in installation. His physical strength and enthusiasm are constantly consumed, and he gradually shows a little fatigue.

According to this progress, it will take at least half a month to install the entire equipment.

Zhang Shengguo and Sun Yaohua each have a lot of things, so it is impossible for them to stay here all the time. Besides, they don’t understand technology, so staying is useless to waste time. After watching for a while, they didn’t realize their reputation. They learned that it was impossible to wait for the result today, so they said hello to Guan Fei and went to do their own thing.

Guan Fei did not leave. He used the programmer he brought to enter control data on the spot for each qualified industrial control board on the equipment.

After working on technology in this era for so many years, Guan Fei has gradually become a master.

If it were in an era when everyone had biological subbrain, his level could be said to be terrible. It was a standard civil science, and what he produced would only be ridiculed by experts. But in this era, he was a real top expert.

Without high-energy bioenergy support, the biological auxiliary brain cannot perform large-scale data operation (compared in Guan Fei's era), but there is no problem in performing small-scale data operations. It is just that the brain is hypoxia after calculation and is a little dizzy.

But the speed of these so-called small-scale operations is a super-high speed that even supercomputers cannot achieve in this era.

Guan Fei cannot perform overall simulation operations, but he can bring variables into each moving part and substitute them into a formula for calculation, thereby calculating the stress position, direction, and source of each component. Then he obtains an accurate number for the stress requirements of different stress parts of the component, and then calculates the required materials, processing accuracy, and processing methods to meet different standards.

After constantly adjusting the variable data, a complete set of drawings is designed.

Therefore, the vacuum electroslag remelting furnace drawings he submitted were not the original sample in the database. Instead, based on the technical level of this era in China, the drawings that can be produced were recalculated. Perhaps in a few years, with the advancement of various technologies, a better vacuum electroslag remelting furnace can be created, but in this era, it is an optimized equipment that is capable of manufacturing in China.

For actual use, if the domestic system has not fully understood the principles, or only partially digests the technology, and comprehensively optimizes it, and then writes the most scientific operating process. Perhaps the refined alloys of the same type of equipment manufactured in China in ten years are not as good as it!

During the local simulation operation, the corresponding action control program has been automatically formed.

Guan Fei is now just entering it into the main control memory to solidify it. It is a boring and repetitive physical work for him, without any technicality or fun.

So he simply handed everything over to the biological brain, but his thoughts drifted out of the sky and began to think about other things.

His actions soon attracted the group of experts who were strictly inspected by the military sub-district and were dragged to nothing and were somewhat physically and mentally exhausted.

When he saw that he was entering the industrial control program that everyone was most concerned about, everyone immediately became very concerned about.

I don’t know if Guan Fei is willing to teach them this program, and he did not invite him, so the experts winked at each other. Some experts who don’t know how to program act as walls, blocking the view of the military sub-district, covering their companions’ way of pretending to be nothing, moving to Guan Fei little by little, widening their eyes, trying to see every input from Guan Fei, and doing their best to keep it in their minds.
