"What, you're going to use a 150 megapascal ultra-high pressure vessel here? We can't do this, not to mention us, that is, no one in the whole country has this qualification, more than 100 megapascals is ultra-high pressure, and there are two or three high-pressure vessel qualifications in China. ”

Looking at the sketches drawn by Li Jian in detail, especially the few places marked with key points, they turned out to be ultra-high pressure vessels, Lin Kaihe shook his head, the ultra-high pressure container is not like other things, the pressure inside is too large, in case there is a weld that cannot withstand the high pressure in it, it will cause a huge production accident, and no one dares to touch such a high-voltage line.

"You're afraid that the weld won't be able to withstand such high pressure, right?"

Li Jian asked, Li Yuelong pouted contemptuously, it seems that this Li Jian only knows a little bit of technology, and I don't know where to hear about this set of production processes, the weld of the ultra-high pressure vessel is only one aspect, the pressure resistance of the steel plate of the container itself is another direction that needs to be considered, and the sealing ring at the interface of the container is another fatal point of the pressure-resistant container.

The pressure resistance requirement of 150 megapascals was no less than climbing Mount Everest with bare hands for the machinery industry in this period.

"Not only the welds, but also the 150 megapascal pressure test on our steel plates, and the current pressure resistance of our sealing rings can only reach 75 megapascals at most, which is simply excessive for performance requirements."

Lin Kaihe drew a difference on several ultra-high pressure vessels, and then pointed to another place marked with a red dot.

"The low-temperature resistance of this reactor cannot be reached by the current steel plate in our country, and the steel plate that meets this requirement is embargoed to China anywhere in foreigners, and we can't buy it even if we have foreign exchange, I'm afraid it is more difficult to solve than the high-pressure resistant steel plate."

Lin Kaihe stretched out his tongue and licked his lips, he was very helpless, the field exploration was done, he originally thought that this small-scale ethanol refining production line was a piece of cake, but when Li Jian took out his specific requirements, he didn't expect it to be such a hard bone, no matter how Li Jian got such a production process, but just looking at such strict requirements, I know that with the current strength of Shengli Design Institute, there is no way to solve it, even if you add Daqing or several other machinery factories, there is still no way to get it, The limitations of materials cannot be shifted by human will.

"Boss Li, where did you find the process flow, don't just write a few data on it, do you know the difference between fifteen megapascals and one hundred and fifty megapascals? This is not the same as the difference in the current on the telephone, don't look at the extra tens of megapascals, this is a decades of technological gap, no one in China dares to tell you that such a device can be made. ”

After Li Yuelong's visit to Zhang Zhihua the day before yesterday, he knew that Li Jian did have some strength in electronic communications, but he still did not prevent Li Jian from looking down on Li Jian in the chemical industry, which was just unwarranted jealousy, and he did not want to admit that the knowledge he had worked so hard to obtain was not as good as that of a student who did not graduate from high school, even if this student showed a genius in the communication industry.

"Not at the moment, but it will be soon."

Seeing the current domestic steel level and the overall pouring level, far from reaching the glorious period after a few decades, Li Jian also scratched his head, there are only two ways to go, one is to seek foreign chemical enterprise cooperation, but then the prospect of non-coal and non-oil chemical industry will be discovered by foreigners, if they follow their own production process flow chart for reverse restoration, they are very willing to figure out the production principle within a certain period of time, and then bypass their own patent barriers, the same production.

Non-coal and non-oil chemical industry, but after a few decades, when the oil resources are limited, the new industry that has been vigorously developed, the set of equipment picked out by themselves, basically belongs to the minimum requirements, this epoch-making industry is only symbolic in the oil resources are sufficient, but when the oil resources are almost exhausted or restricted, that is to affect the development of a country.

The second way is to improve the level of domestic steel casting industry and industrial design, but this requires cooperation with iron and steel enterprises, but also with design enterprises.

At present, the domestic iron and steel enterprises, I am afraid that they are all state-owned enterprises, and basically have to be state-owned enterprises above the county level, one by one, even if they are on the verge of bankruptcy, they don't care, there is a government to wipe their buttocks, and they will not worry about the lack of oil and water.

Even if he proposes to help them with technical transformation for free, I am afraid that it will be a hot face and a cold ass, and mechanical design companies are all branches affiliated with major state-owned enterprises, such as Shengli Design Institute, it is completely to improve the treatment of their internal employees, so they will agree that Lin Kaihe will take Li Yuelong and two people to Qianghua, and if they want to talk about cooperation, I am afraid that they will be kicked out.

Seeing Li Jian falling into deep thought, Li Yuelong thought that Li Jian couldn't erase the face that he had been counted down.

"If Boss Li can invite people in China to help you solve the problem of high pressure and low temperature resistance, I Li Yuelong will complete this design for you for free."

Li Yuelong only dared to say that he was free, anyway, he was an intern, so he didn't have much money to take at all, but as for Lin Kaihe, he didn't dare to sit in charge.

"Professor Lin, what level of treatment do you enjoy in the Provincial Machinery Factory Research Institute?"

Li Jian didn't pay attention to Li Yuelong, but thought of another problem, if you want to cooperate, it is better to do it with Lin Kaihe, his own industrial process design has been seen by Lin Kaihe, and Lin Kaihe's work attitude also makes Li Jian feel satisfied, there is no kind of dog-eyed behavior that looks down on people, and he can do his best to consider Li Jian's requirements.

"Where do I have any treatment, now I am an ordinary researcher, and my monthly salary is only three hundred and forty yuan, which is just enough for my wife and children to eat."

Lin Kaihe smiled, he is a native of Ludong, and he has been working in victory for a few years, but because he is humble and honest, he doesn't like the leader very much, so he didn't have his share in several promotions, and all these years have been doing small work like Qianghua, as for the kind of design that makes a lot of money, basically he doesn't have his share.

"Then if Qianghua hires Professor Lin to work in Chunjiang, solve the housing and your lover's work for you, and pay you three times the salary level of the Shengli Machinery Factory Research Institute at the same time, are you willing to work in Qianghua?"
