In the end, it was not only Tang Yong who came over, but also Sigmund. Mia, the future "mother of heavy-duty diesel engines" who had interned at Daimler MTU, was stupid when she heard Lin Hongfei say that he would develop a large mining dump truck with a rated load of 105 tons on the basis of the current Z12V190B diesel engine of Shungeng Diesel Engine Factory.

Thanks to the blessing of working in the construction machinery company during this time, Tang Yong has a preliminary understanding of the special alternative construction machinery of those large mine dump trucks with a load of one or two hundred tons. Gearbox and suspension, can you solve the problem of materials? Although the profits of this super-large construction machinery are attractive, the material requirements are very high, and we simply do not have the steel to meet the requirements to produce these things. ”

This is very reasonable, many domestic designers are not unable to design good products, but limited by the domestic material manufacturing process and level, because the material can not meet the design requirements, these design things can only stay on paper, Lin Hongfei last time and FAW cooperation dump truck is the current Guqi Provincial Industrial Manufacturing Co., Ltd. in terms of materials can reach the limit, those are only dozens of hundreds of tons of behemoths? This is beyond the level of costs that can be controlled at present...... It really has to be built, and it's not that it can't be built, but the cost is higher than that of imports, and it's really not cost-effective.

Lin Hongfei seemed to be confident, and turned his head to Sigmund. Mia asked, "Mia." Do you have the right steel formula here? If there is, the company will buy it from you at a reasonable price. ”

"Nope." Sigmund. Mia shook her head, "I'm only an intern at MTU, and I'm not qualified for this level of secret. ”

"That's a pity," Lin Hongfei said with a regretful face, but looking at him like that, he didn't seem to be able to see pity at all, "But Mr. Liu Laizhi, the chief designer of Shungeng Diesel Engine Factory, gave me a copy of the steel formula developed by his teacher back then, I don't know if it is useful." ”

"Old Liu's teacher?" Tang Yong was confused, "Is he famous?" ”

"It's not very famous. It can only be regarded as generally famous," Lin Hongfei said in a casual tone, "Before liberation, he used to be an artillery designer for tanks in the Krupp Arsenal in Germany, and he was also one of the main designers of Krupp carburized armor steel, and he once studied in the Department of Mechanical Engineering of the Technical University of Berlin in Germany. He obtained a chartered engineer degree, and served as a teaching assistant and researcher at the Institute of Theoretical Mechanics of the Technical University of Berlin. He also received his Ph.D. in Natural Sciences from the Department of Mathematics and Physics at the University of Göttingen, Germany. Well. If I'm not mistaken, he also worked as an engineer at the Turbo Manufacturing Plant in Sullichjokan, Switzerland. Later, after the victory of the Anti-Japanese War, he returned to China under the struggle of the country, and successively served as the chief engineer of the Dongfang Municipal Public Works Bureau, the professor and dean of Tongji University, the professor, first-class professor, and vice president of the Guqi Provincial University of Technology, the deputy director of the Guqi Provincial Mechanics Society, the vice chairman of the Fourth and Fifth CPPCC of Guqi Province, the academician of the Chinese Academy of Sciences, and the vice governor of Shandong Province a few years ago. ”

"Is there such a powerful person in our country?" Tang Yong's saliva was about to flow down when he heard it, but he tried hard to think about it, and he couldn't think of such a bullish figure in the republic. "Why haven't I heard of such a powerful character?"

"Won't it?" Lin Hongfei didn't believe it, ordinary people hadn't heard of the deeds of this super bull, how could Tang Yong not have heard of it? "Back then, when we were clashed by polar bears, this bull man helped the country solve the key equation of anti-tank ammunition."

"It turned out to be Professor Liu!" I don't know what else to say. But as soon as he talked about it, Tang Yong immediately remembered who this super bull in Lin Hongfei's mouth was: who else could it be besides Professor Liu Zhi, a former academician of the Chinese Academy of Sciences?

Professor Liu Zhi is a well-known scholar, mechanics expert, educator, and a well-known patriot, enjoying a high reputation at home and abroad, when his name is mentioned, many people first think of him as he has made important contributions to the scientific cause and education of the Republic, as well as the party's united front work and CPPCC work, but I am afraid they do not know the way, Professor Liu Zhi has also carried out research work in many fields such as solid mechanics, fluid mechanics, general mechanics, vibration dynamics, heat transfer, applied mathematics and mechanical engineering. And has made great contributions, as far as pure technology and science are concerned, if there are no political factors, Professor Liu Zhi's level is not less than two dollars for top-notch national defense.

Since 1945, Professor Liu Zhi has published more than 60 scientific papers, including Introduction to Mechanical Vibration and Liu Zhi's Collected Papers. He has made significant scientific research achievements in the fields of theoretical mechanics, fluid mechanics, elastic mechanics, vibration, thermal stress, heat conduction, applied mathematics and basic theories of mechanical engineering.

His research on thermal stress has filled a gap for the country and is of international level; In terms of vibration and balance, he proposed a scientific and practical calculation method, which attracted the attention of foreign counterparts.

He wrote four papers on the balance of second-order reciprocating inertia forces of planar crankshaft eight-cylinder V-type internal combustion engines, created three balance schemes, and solved a major problem of vibration caused by inertial forces, which are known as "three important inventions", which are of guiding significance for production, teaching and further theoretical research.

Speaking of Liu Lao's glorious past, Tang Yong's eyes consciously carried reverence, and while speaking, he suddenly reacted, and the expression on his face became excited, it was the kind of extreme excitement, for example, when you didn't drink a sip of water in the desert for three days, you suddenly found that there was a blue lake in front of you The kind of excitement that is difficult to express in words, "Mr. Lin, do you mean that the formula of this steel is the steel formula provided by Professor Liu?" ”

Professor Liu is a cow who has designed carburized armor steel, and it is not simple to design a special steel that meets the conditions for the use of minecarts? If there is a steel formula provided by Professor Liu, an engine, a clutch, a gearbox and a suspension system, then the operability of this matter will be much greater. Thinking that the Beijun Construction Machinery Factory, which has always been able to produce low-cost construction machinery, actually wants to produce the crown jewel of construction machinery: mining vehicles, Tang Yong was excited and trembled slightly, if this is really a successful mining vehicle with a rated load capacity of 100 tons, it is the only one in the country.

"Well, Engineer Liu Laizhi once studied with Mr. Liu Zhi, and he is half of Mr. Liu's closed disciple," Lin Hongfei nodded, now he thinks that Lin Hongfei's head is dizzy, he didn't expect that Mr. Liu Laizhi, the designer of Shunchai 190 series diesel engines, gave Mr. Liu a steel formula to himself without mentioning any conditions, "The formula of this steel was given to Mr. Liu Laizhi by Mr. Liu Zhi three years ago when he passed away and self-examined to Liu Laizhi's designer, but this steel formula has not been verified. The conditions of the Shungeng Diesel Engine Factory also did not allow them to do such a test, which was too expensive. ”

"It's okay, they don't have money to do experiments, we have money, as long as this steel formula can meet the requirements of super-large mining vehicles, it's worth it to spend a test test," the current big boss Tang Yong Tang is wealthy, and he didn't blink his eyelids and said, "Allocate 10 million first, it's not enough." ”

Nima! Isn't it a bit extravagant to spend 10 million yuan to verify whether a special steel formula can meet the strength, hardness and elasticity requirements of mining vehicles? Lin Hongfei was very depressed, looking at Tang Yong's eyes as if he was looking at a super-large loser, but he said, "It's a pity, the hydraulic press in our company is still small, and this thing is inseparable from the large-tonnage hydraulic press, hydraulic press, and die forging machine." ”

"Then let's get it from Lao Maozi again!" Tang Yong waved his hand indifferently, in the past few years, taking advantage of the chaotic situation on Lao Maozi's side, Guqi Provincial Industrial Manufacturing Co., Ltd. really got a lot of good things from Lao Maozi, but the situation in front of him made Tang Yong thoughtful, "However, Mr. Lin, I think we should pay attention to Lao Maozi's research institutes and other research and development units in the future, and the technology and research and development materials in them can't be obtained with money." ”

These things are waiting for you to think that the daylilies are cold. Lin Hongfei couldn't help but sigh at Tang Yong's hindsight, and couldn't help but remind him, "You forgot, the data building specially built by our company, just the various materials from Lao Maozi filled the entire seven floors, but the current data sorting work has not been completed, otherwise it will ......"

Otherwise, there is no need to take the steel formula from others, maybe our data building has the required steel formula information. Lin Hongfei's meaning was obvious, but Tang Yong was very disappointed: What year and month should the mountain-like information be sorted out by the ghost?

"It's a pity, Mr. Liu left too early, he left in 90 years, and he only lived to be 84 years old," Lin Hongfei said, smacking his lips reluctantly, "A national treasure like Liu Lao, I don't dare to say that I should live to be 100 years old and 95 years old, right?" After hearing that Mr. Liu was gone, the relevant departments directly packed Mr. Liu's life's research efforts and took them away, and I don't know which corner of the road was sent to become moldy...... How nice would it be to send it to our company? ”

I was very excited to hear it before, but when I heard it back, Tang Yong pouted in his heart: I guess what you really think about is the various research materials that were directly packed and taken away by the higher departments after Liu Lao left, right? (To be continued.) )
