    ps: While there are still some free words in this chapter, let me say something here.  Old readers who are familiar with the author know that the author is handicapped, and the meager manuscripts he originally had were used up in a few days.  In addition, this is a realistic science and technology novel. In order to write a technical project well, you need to check a lot of information and understand it in detail, at least without making stupid mistakes. This will take several hours.  At the same time, it takes a lot of effort to find interesting highlights for readers in boring technical information.  Sometimes it happens that the information prepared for the outline is found to be inappropriate for the current progress, and it must be overturned and re-conceived.  So although the author also wants to speed up the process and update three or five chapters a day so that everyone can read it happily, the writing progress cannot be accelerated.  I can only write and post as I go. The update time may be sooner or later, and cannot be fixed, and the volume may be more or less. I can only apologize to everyone here with shame, and I hope you can understand.   Sun Yaohua took advantage of the fact that no one was paying attention, and leaned into Guan Fei's ear, whispering in a mosquito-like voice: "Is this the refining furnace you were talking about? With it, can we make our own artillery?" "  Of course, no problem!" Guan Fei replied in the affirmative and added, "Producing high-quality gun steel is only one of them. More importantly, with it, we can smelt very good bearing steel and spring steel.  , tool steel, and various high-quality special alloys. " "Really? Why do I think it is more exciting to produce gun steel?" Sun Yaohua blinked and laughed a few times.  He understands that bearing steel and other things must be good things.  But for him, who has been fighting for many years, those things are too far away from him and he has no practical concept.  There is no high-quality steel that can be refined to make gun barrels to make him feel taller.  Guan Fei rolled his eyes at him, helpless.  For those who don¡¯t understand, no matter how hard you explain, it¡¯s all in vain.  Compared with refining gun steel, vacuum electroslag remelting furnaces play an irreplaceable and important role in improving precision manufacturing technology.  Gun steel and other things can also be smelted with electric arc furnaces, and the mass production capacity is several times that of vacuum electroslag remelting furnaces, so qualified gun barrels can be produced in large quantities.  But the physical properties of the same steel ingots smelted by the vacuum electroslag remelting furnace are more than ten times that of the arc melting furnace!  Even compared to ordinary electroslag remelting furnaces without vacuum seals, the quality is several times higher!  This means that the gyroscopes, bearing balls, lathe guide rails, and lathe tools produced by refining steel ingots in vacuum electroslag remelting furnaces have smoother surfaces, higher precision, impact resistance and wear resistance, and service life, which are both superior to other similar products.  to several times.  The strength of vacuum pressure-resistant shells, engine combustion chambers, and aircraft load-bearing beams made from special alloy steel ingots refined by vacuum electroslag remelting is also much higher than that of the same type of special alloys!  Its importance is immeasurable!  In this era, it is an important weapon of the country!  If it weren¡¯t for the fact that the country had roughly mastered the manufacturing technology of electroslag resmelting furnaces, it would have popularized this equipment in special alloy factories across the country.  However, due to deficiencies in theoretical support, experimental data, and machining, the quality of steel ingots is indeed better than alloys produced by other refining methods, but it is not yet amazing.  For the country currently, the true 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 taken it seriously enough to regard it as a treasure.  Of course, it would be too naive to say that the country has no defense against military divisions and will give whatever it wants.  If it were not for the desire to earn foreign exchange from the military division, the upgraded vacuum electroslag resmelting furnace technology provided by Guan Fei would also be very attractive to the domestic market. We are eager to know whether his improvements are effective.  Unfortunately, Guan Fei provided the manufacturing drawings but not the main control program, so he couldn't test it secretly.  In addition, the country is still swinging back and forth between the left and the right, and it still has considerable sympathy for the fraternal parties. The military divisions are now prosperous, and their status in the hearts of the domestic high-level officials is getting higher and higher.  Under the combined effect of various forces, they showed an attitude of keeping their promises and delivered the produced parts to the military division as scheduled.  But at the same time, in the name of assisting in installation and test runs, a large number of experts in metallurgy, machinery, and automation were sent to actually inspect the improved vacuum electroslag remelting furnace through the actual grasp of test run data.  What is the refining ability?  If it is better than what is developed domestically, then of course you have to ask Guan Fei for it.  If it is not as good as at home, then of course there is no need to care.  Even if some gun steel can be refined, the quantity will not be too large. With the current processing level of the military division, it can only be produced in small quantities and will have little impact.  If it weren¡¯t for these considerations, the country would never have handed over such advanced equipment to the military division.  In fact, Guan Fei is not sure that the country will replace the armyThis set of vacuum electroslag remelting furnaces is manufactured in zones.  For the sake of safety, one hand was specially reserved to be used in exchange for inferior arc furnaces and continuous casting equipment.  The goal is to slowly upgrade, and when you have the corresponding capabilities, you can then build a vacuum electroslag resmelting 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 subdivision, informed him that the equipment was ready and on the road and would be delivered to the military subdivision unexpectedly, he was so happy that he almost jumped up.  In a state of excitement, he ran up to Zhang Shengguo and Sun Yaohua and boasted a few words, excitedly saying, "With this set of equipment, the precision manufacturing capabilities of the military division have been increased by ten years at a time." This attracted a lot of attention.  The two of them were so curious that they rarely put down their busy work and ran with him to watch.  Even now, after experiencing so many things and having already developed a steady mind, he still smiles unconsciously.  The way he looks at the device is like looking at his beloved girl, extremely gentle.  Good stuff, really good stuff!  ¡°It¡¯s hard for China to be so generous and send him such good things.  But it¡¯s no wonder.  Although it has been studied for more than ten years, domestic people have not yet fully understood this technology, and of course they do not 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 alloy refined using the same formula are better.  However, in order to fully utilize its capabilities, excellent technical operators, scientific operating procedures, and precise control technology are required.  The most important thing is that it requires the support of huge experimental data and 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.  ??????????????????????????????????????????????Why are the steel ingots produced in China using electroslag remelting furnaces higher in sulfur content than those in the Soviet Union, and their strength, wear resistance, and lifespan are not as good as Soviet products?  It¡¯s just that these data are missing!  Without countless investment in testing, there would be no corresponding data support, and it would be impossible to have tens of thousands of material formulas that producers can pick up at their fingertips to smelt special alloys that meet the requirements of product requirements to meet the needs of manufacturers.  .  ??Apparently domestic military divisions are regarded as this kind of users. They simply think that vacuum electroslag remelting furnaces are good, but they don¡¯t know that there are so many and demanding follow-up requirements behind them, and they are not optimistic about its prospects.  From a domestic perspective, instead of a flashy vacuum electroslag remelting furnace, the military division would be more practical to purchase an arc melting furnace with worse technology but lower requirements and greater output.  Guan Fei looked at the group of domestic experts who were enthusiastic and couldn't help but run up to help with the installation. He couldn't help but curl up the corners of his mouth again.  The installation of vacuum electroslag remelting furnace is very time-consuming.  The installation of a vacuum electroslag remelting furnace is a particularly precise project, but the vertical error of the first few support columns of more than ten meters in the factory must not be greater than 0.1 mm.  After the support columns are erected, the apex 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 specially mobilized a large number of elite soldiers from various factories and brought a large number of precision measuring equipment to ensure that this equipment would be 100% problem-free.  This has slowed down the progress of the entire installation. The installation has stopped and the installation has stopped. As an expert assisting in the installation, the physical strength and enthusiasm are constantly being consumed, and gradually showing signs of 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 their own affairs and cannot stay here forever.  Besides, they don't understand technology, so staying here will be a waste of time.  After watching for a while but not seeing anything, the two of them learned that it was impossible to wait for the result today, so they said hello to Guan Fei and went about their own business.  Guan Fei did not leave. He used the programmer he brought to input control data on-site for each qualified industrial control board on the equipment.  After so many years of developing technology in this era, Guan Fei has gradually become a master.  "If it were in an era where everyone had a biological accessory brain, his level would be terrible. It was a standard civilian science, and what he produced would only be ridiculed by experts.  But in this era, he is truly a top master.  Lack of high-energy biological energy support, the biological accessory brain cannot perform large-scale data operations (compared to Guan Fei's era), but there is no problem in performing small-scale data operations. However, after the calculation, the brain is deprived of oxygen and feels a little dizzy  But the speed of these so-called small-scale operations is ultra-high speed that even supercomputers cannot reach in this era.  Guan Fei cannot do the overall simulation calculation, but he can bring variables into each moving part and substitute them into the formula for calculation, thereby deducing the stress position, direction and source of each component, and then calculating the force stress of different stress parts of the component.  It is necessary to obtain an accurate number, and then calculate the materials, processing accuracy, and processing methods required to meet different standards.  After continuously adjusting the variable data, a complete set of drawings will be designed.  So the vacuum electroslag remelting furnace drawings he submitted were not the original set of samples in the database.  Instead, based on the domestic technical level of this era, we recalculated and came up with drawings that could be manufactured.  Maybe in a few years, with the advancement of various technologies, better vacuum electroslag remelting furnaces can be manufactured, but in this era, it is the most optimized equipment that China can manufacture.  Specific to actual use, if the country has not fully understood the principles, or only partially digested the technology, fully optimized it, and then compiled a set of the most scientific operating procedures.  Maybe the same type of equipment manufactured in China ten years later will not be able to refine the alloy as well as it!  During the local simulation operation, the corresponding action control program has been automatically formed.  Guan Fei is just inputting it into the main control memory to solidify it. For him, it is a tedious and repetitive physical work, without any technicality or interest.  So he simply handed everything over to the biological assistant brain, but his thoughts drifted to the sky and started to think about other things.  His actions quickly attracted a group of experts who were left idle and exhausted physically and mentally by the strict inspection procedures of the military division.  When they saw that he was inputting the industrial control program that everyone was most concerned about, everyone immediately became attentive.  I didn¡¯t know if Guan Fei was willing to teach them this program. He didn¡¯t invite them, so the experts looked at each other. Some experts who didn¡¯t understand programming acted as a human wall, blocking the view of the military division and covering the equipment of their companions.  Tsukuru walked around casually as if nothing had happened, and moved little by little to Guan Fei's side. With his eyes widened, he tried to understand every input from Guan Fei and tried his best to remember it in his mind.  Even though they were slowly approaching in twos and threes, as time passed, Guan Fei was still surrounded by experts from China.
