Chapter 352: Always go back with something

When Yang Hui walked in, he saw the doorway inside, especially the processing of engine compressor blades.

"The processing process of these titanium alloy blades is indeed very distinctive"

Yang Hui silently compared the titanium alloy blade processing in the trial production of the fast reaction center engine with the titanium alloy processing method of the previous face, and came to the conclusion that there are many differences between the two processing technologies, but not too big.

The titanium alloy processing technology of the Soviet Union matured very early, and in some respects it was even more awesome than that of the US imperialists, otherwise it would not be possible to manufacture super submarines: all-titanium alloy hull submarines such as the Papa-class and Barracuda-class have reached almost perverted speed, depth, and silent levels.

However, in Yang Hui's comparison, some differences were found, although the current titanium alloy processing technology of the Soviet Union is very good, but the level of automation is relatively low, most of them are some semi-automatic machine tools for processing, and the United States imperialism, the Republic of the Republic of automation precision machine tools have a big gap.

Of course, in the current Yang Hui's view, the Soviet Union's titanium alloy processing technology is absolutely drooling, and the semi-automatic big deal is that it is more time-consuming and labor-intensive, at least much better than pure manual operation of machine tools.

As for the so-called material loss, there is really nothing to say, before the application of 3D additive printing technology, most of the metal processing technology was cutting, and the chemical corrosion method was actually regarded as material processing.

These will cause 'waste', in fact, these cut materials can be collected and remelted. The losses are not too great.

When Yang Hui saw the titanium alloy blades being processed, his saliva was about to flow out. If Southwest Science and Industry can master this technology, not only engine manufacturing can be of great benefit. Even aircraft building can benefit greatly, isn't this drooling what is?

Xi Luojing saw Yang Hui's appearance, and naturally knew the reason why Yang Hui drooled, although it was quite bitter, but his heart was very useful, this is the gap between the basic industries of the two countries, titanium alloy manufacturing technology, this is the high-end processing industry of the powerful country, Hua

Xia still doesn't understand this.

"That's right. This is the manufacturing process of our titanium alloy compressor blades, with it, our aero engines can get great gains, not only the weight can be reduced, but the mechanical properties of the blades will also be greatly improved. ”

When he introduced the titanium alloy processing technology that the Soviet Union was proud of, Vice President Shirodin was very proud and motioned to the technicians to continue the trial production of blades.

"Titanium alloy processing is very difficult, and the thermal conductivity of the metal itself is low, which is prone to spontaneous combustion and burns. Therefore, the cold-blooded requirements in processing are very high: its metal elastic modulus is small, and the requirements for the tools used in processing are not low, and it is almost impossible to achieve titanium alloy processing without good cutting tools. ”

Xi Luojing's introduction is very simple, because Yang Hui has seen the processing of titanium alloys in later generations. Naturally, I know some of the precautions, in titanium alloy processing, the requirements for tools are simply perverted.

Titanium alloys themselves are prone to bond chips to the tool during machining. On the other hand, because the titanium alloy is too hard, the wear on the tool is very large.

Even in the machining of larger parts. The degree of wear of the tool at the beginning of machining is very different from the wear and tear at the halfway point and to the end of the machining stage.

Due to the machining process, the tool is worn too much. As a result, the machining accuracy of the parts is reduced, which is probably only unique to the process of titanium alloy machining.

This is only the problem of the tool itself in the processing process, the use of CNC machine tools, taking this into account when writing the program, the requirements for machining accuracy can make up for it.

Think about it from another aspect: since the wear and tear of tools is large and fast, this brings another problem, and the procurement channels of tools must be stable.

Why do you say it once? High-performance tool manufacturing, Yang Hui said, this is simply more disgusting and perverted than high-performance machine tool manufacturing, which is completely through continuous testing of materials, and finally tried. Sorry, the later Republic of China in the development of titanium alloy processing tools, that is also the biggest weakness.

Fortunately, the Republic of China has obtained the manufacturing method of titanium alloy processing tools through some special methods, which is a matter of course. In the case of a large consumption of knives, the republic can provide its own relatively stable tool procurement channels.

But now it is the 80s, Yang Hui can't think of any good way to get a stable knife procurement channel, after all, the international environment of the republic in the 90s is like that, and it is almost impossible to purchase stably from Western countries.

There is no stable tool procurement channel, and Yang Hui did not spend a lot of effort on titanium alloy processing machine tools, processes, etc. after being reborn.

The unstable source of processing equipment is the sword of Damocles for industrial products made with titanium alloy processing technology.

But now it's different, Yang Hui thought of another opportunity through this trip to the Soviet Union, the so-called East is not bright and the West is bright, and the surname is unstable, so let's go to the surname society.

The titanium alloy processing industry in the Soviet Union is also very good, and the most important thing is that you can start preparing now, at least after getting the Soviet titanium alloy processing technology, there will be no danger of being stuck.

If you really feel unsafe, after the collapse of the Soviet Union, you can start directly from the Soviet Union, study the entire titanium alloy processing industry chain, or copy and copy, as for what tools are small problems.

Even, Yang Hui guessed that in the upper plane, the tool manufacturing technology used in the republic's titanium alloy processing was obtained from the Soviet Union, and now Yang Hui is more confident.

"The titanium alloy processing technology of the Soviet Union is indeed quite good, we are very envious, I don't know if it is to cooperate on this, our republic needs this kind of thing, of course we are willing to spend dollars to procure."

As soon as he finished speaking, Yang Hui suddenly remembered a huge and influential thing in later generations, maybe he could use it, which could be used to help the titanium alloy processing technology this time.

Yang Hui began to plan silently, but the Soviet Foreign Ministry and Vice President Shirodin on the side seemed to hear a joke, how could the Soviet Union transfer such an important technology to a country like the Republic, after all, there were still hundreds of thousands of soldiers on the border between the two countries.

"No, no, no, this is absolutely impossible, titanium alloy processing technology is absolutely impossible to provide to you, this technology is too important, with the current relationship between our two countries, it is absolutely impossible."

As for Yang Hui's purchase of dollars, the current Soviet Union is still 86 years, although the society is going downhill, but there is no economic collapse, the demand for dollars is not too obvious, and the foreign exchange ** disease has not appeared.

Of course, since Gorbachev has come to power and social reform has begun, many people have begun to yearn for Western society in their hearts, and naturally they also yearn for the green dollar, such as this senior official of the Soviet Foreign Ministry, who is still very envious of the dollar Yang Hui said in his heart.

Yang Hui had already guessed this kind of ending, and he was not surprised, Yang Hui's killing move was still to come.

Yang Hui was deeply impressed by the visit along the way, such as the large rotor overrotation test bench used for compressor testing, which is driven by an electric motor, and every start is costly; There is also a total of 25,000 square meters of strength and vibration laboratory; There are also full-temperature, full-scale turbine tests

Seeing this strong technical background, it deepened Yang Hui's determination to open up the aviation industry of the Republic, especially the titanium alloy processing technology that Yang Hui is ready to get his hands on this time. (To be continued.) )
