PS: While there is still a bit of free word count in this chapter, I will say something here. Pen % fun % Pavilion www.biquge.info

Veteran readers who are familiar with the author know that the author is a handicap, and the original pitiful 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 you have to swallow dates to figure out a rough idea, at least you won't make low-level mistakes, which will take several hours. At the same time, it is quite painstaking to find the sparkle that the reader finds interesting in the boring technical materials. From time to time, it happens that the materials prepared for the outline are found to be not applicable to the current progress, and must be overturned and reconceived.

So although the author also wants to speed up and add three or five chapters a day to make everyone happy, the writing progress is really not fast. It can only be written and sent, the update time is early or late, it can't be fixed, and the amount is sometimes more and less, so I can only apologize to everyone here, and I hope to be considerate.

……

Sun Yaohua took advantage of the fact that no one was paying attention, leaned into Guan Fei's ear, and whispered in a mosquito-like voice: "This is the refining furnace you said?" With it, will we be able to build our own artillery? ”

"Of course no problem!" Guan Fei replied in the affirmative, and added, "The production of high-quality cannon steel is just one of them. What's more, with it, we can smelt very good bearing steel, spring steel, tool steel, and a variety of high-quality special alloys. ”

"Really? Why do I think it's more exciting to produce cannon steel? Sun Yaohua's eyes blinked, and he laughed embarrassedly.

He understands that bearing steel or something, it must be a good thing. But for him, who has fought for many years, those things are too far away from him and have no actual concept. There was no high-quality steel that could be refined to make the barrel, which made him feel even more lofty.

Guan Fei gave him a blank look, helpless.

For those who don't understand, no amount of explanation is in vain. Compared with the ability to refine gun steel, vacuum electroslag remelting furnace plays an irreplaceable and important role in the improvement of precision manufacturing technology.

Cannon steel can also be smelted in an electric arc furnace, and the mass production capacity is several times that of a vacuum electroslag remelting furnace, which can produce qualified barrels in large quantities.

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

This means that the steel ingots refined by vacuum electroslag remelting furnace are made of gyroscopes, bearing balls, lathe guide rails, and lathe tools with smoother surfaces, higher precision, impact and wear resistance, and service life, which are two to several times that of other similar products. The strength of the vacuum electroslag remelted and refined special alloy steel ingots, the vacuum pressure-resistant shells, engine combustion chambers, and aircraft bearing beams manufactured by vacuum electroslag remelting and refining are also much higher than those of the same type of special alloys!

Its importance is immeasurable!

In this era, it is a proper national weapon!

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

Therefore, China attaches great importance to this technology, but it has not yet paid attention to it to the point of being a treasure.

Of course, it would be naïve to say that there is no defense of military divisions in the country and that they will give whatever they want.

If he didn't want to earn foreign exchange in the hands of the military division, the upgraded vacuum electroslag remelting furnace technology provided by Guan Fei was also very tempting to China, and I was eager to know if his improvements were effective. However, because Guan Fei provided the manufacturing drawings, but did not give the main control program, he couldn't do it secretly if he wanted to. In addition, the country is now swinging back and forth between the left and the right, and there is still considerable sympathy for the fraternal party, and the military sub-districts are now thriving, and their status in the hearts of the country's top leaders is getting higher and higher. Under the combined effect of various forces, they showed an attitude of keeping their promises and delivered the parts and components produced to the military sub-districts on schedule.

However, at the same time, in the name of assisting in the installation and testing of the machine, a large number of experts in metallurgy, machinery and automation were sent to actually investigate the refining capacity of the improved vacuum electroslag remelting furnace through the practical grasp of the test machine data.

If it is better than domestic research and development, then of course you have to ask Guan Fei for it. If it's not as good as in China, then of course you don't need to care. Even if some cannon steel can be refined, the quantity will not be too large, and the current processing level of the Israeli military division can only be manufactured in small quantities, and the impact is not great.

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

In fact, Guan Fei was not sure that China would manufacture this vacuum electroslag remelting furnace for the military division. For the sake of safety, one hand was deliberately retained, and it was intended to be used in exchange for slightly inferior arc furnaces and continuous casting equipment. The fight is to upgrade slowly, and when you have the corresponding ability, you can make your own vacuum electroslag remelting furnace or other more suitable refining equipment.

When He Tao, the director of the 5**92 unit, who was responsible for liaising with the military sub-division's counterpart, informed him that the equipment had been fully equipped on the road and was about to be delivered to the military sub-district unexpectedly, he was so happy that he almost didn't jump. Under the emotion, he ran to Zhang Shengguo and Sun Yaohua and boasted a few words, and excitedly said that "with this set of equipment, the precision manufacturing capacity of the military division is equivalent to ten years increased at once", which aroused the strong curiosity of the two, and it was rare to put down the busy work in their hands and run with him to watch.

Even now, after experiencing so many things, he has already been trained and has a steady mind, and he still smiles unconsciously. Looking at the device, it is like looking at the girl you love, which is extraordinarily gentle.

What a good thing, what a good thing!

It's hard to think that the country will be so generous and send him such a good thing.

But it's no wonder.

Don't look at the research for more than ten years, but the country itself has not fully understood this technology, of course, I don't realize how important it is.

And just having such a set of refining equipment is nothing.

It is like a sophisticated tool, with it, it can only be said that the physical properties of the refined alloy are better than those of the same formula. However, in order to fully exert its capabilities, it needs excellent technical operators, scientific operation processes, and precise control technology.

The most important thing is that it needs to be supported by a huge amount of experimental data, and it is necessary to have an in-depth understanding of the smelting and processing characteristics of various metals. It is necessary to master a large number of alloy formulas and key smelting technologies.

These things are not even mastered in China, otherwise, why is the sulfur content of the steel ingots produced by the same domestic electroslag remelting furnace higher than that of the Soviet Union, and the strength, wear resistance, and life are not as good as those of the Soviet Union?

It's just the difference in these numbers!

Without countless test inputs, there is no corresponding data support, and it is impossible to have tens of thousands of material formulas, which can allow producers to smelt special alloys that meet the requirements according to product requirements to meet the needs of manufacturers.

Obviously, the country regards the military division as this kind of user, but simply thinks that the vacuum electroslag remelting furnace is good, but does not know that there are so many follow-up requirements behind it, so harsh, and is not optimistic about its use prospects. From a domestic point of view, it is more practical for military subdivisions to have a set of flashy vacuum electroslag remelting furnaces than to have a set of electric arc furnaces with worse technology, but lower requirements and greater output.

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

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

The installation of the vacuum electroslag remelting furnace is a particularly delicate project, but the vertical error of the first few support columns of the plant of more than ten meters shall not be greater than 0.1 millimeter. After the support column is erected, the vertex gap and horizontal error between each column must also be guaranteed to be within 0.2 mm.

Before installation, in order to ensure that the processing parameters of each part meet the requirements, the military division must repeatedly measure each part. To this end, Guan Fei deliberately dispatched a large number of elite soldiers from various factories to bring a large number of precision measuring equipment to ensure that this set of equipment is 100% problem-free.

This dragged on the entire installation progress is never fast, the installation stops, stops and installs, a kind of expert who assists in the installation, physical strength and enthusiasm are constantly consumed, and gradually show a trace of fatigue.

According to this progress, the installation of the whole set of equipment will take half a month, to say the least.

Zhang Shengguo and Sun Yaohua each have their own things to do, and it is impossible to stay here all the time. Besides, they don't understand technology, and it's a waste of time to stay. After watching it for a while, they didn't see the fame, and the two 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 didn't leave, he used the programmer he brought to the site to input control data on each qualified industrial control board on the equipment.

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

If it is in the era when everyone also has a biological side brain, his level can be said to be miserable, it is a standard civil science, and the things he makes will only be laughed at by experts. But in this era, he is a real master.

Lacking the support of high-energy bioenergy, the biological auxiliary brain cannot carry out large-scale data operation (compared with the era of Guan Fei), but there is no problem in conducting small-scale data computing, but the brain is deprived of oxygen after calculation, and it is a little dizzy.

However, the speed of these so-called small-scale operations is ultra-high-speed that supercomputers cannot reach in this era.

Guan Fei can't do the overall simulation operation, but you can bring the variables into each moving part and substitute the formula for calculation, so as to calculate the force part, direction and source of each part, and then get an accurate number for the force requirements of different force parts of the part, and then calculate the materials, processing accuracy and processing methods required to meet different standards.

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

Therefore, the drawings of the vacuum electroslag remelting furnace he submitted were not the original prototypes in the database. Rather, according to the technical level of the domestic era, the drawings that can be manufactured are recalculated and obtained. Maybe in a few years, with the progress of various technologies, a better vacuum electroslag remelting furnace can be manufactured, but in this era, it is the most optimized equipment that can be manufactured in China.

Specific to the actual use, if the country has not fully understood the principle, or only partially digested the technology, and comprehensively optimized, and then write a set of the most scientific operation process. Maybe the same type of equipment manufactured in China ten years later, the refined alloy is not as good as it!

In the process of local simulation operation, the corresponding action control program has been automatically formed.

Guan Fei is now just entering it into the main control memory and solidifying, which is a tedious and repetitive manual work for him, untechnical and uninteresting.

So he simply handed everything over to the biological vice-brain, but his mind drifted to the clouds, and he began to think about other things.

His actions on his side soon attracted a group of experts who were dragged to nothing by the strict inspection procedures of the military sub-district, and some were physically and mentally exhausted.

As soon as they saw that he was entering the industrial control program that everyone was most concerned about, everyone immediately paid 120,000 points of attention.

I don't know if Guan Fei is willing to teach them this set of procedures, and he didn't invite them, so the experts looked at each other, and some experts who didn't know how to program acted as a human wall, blocking the sight of the military division, covering their companions and pretending to walk around casually, moving to Guan Fei's side little by little, widening his eyes, trying to see every input of Guan Fei, and trying his best to memorize it.

Even if he slowly leaned over in twos and threes, as time passed, Guan Fei was still surrounded by experts from China.
