Siheyuan: My Northeastern Farmhouse

Chapter 199 Good things come in pairs

Of course, Qian Weichang was not simply fooling Gu Weijun. The data he was asked to check this time did include a revised design of the diesel engine, including the calculation of external force couples, the normal stress of the cross-section of the axial tension and compression rods, etc.

In addition, there are several assumptions about the calculation of the alloy addition amount to meet the performance of the cylinder block and parts of a diesel engine with a power of more than 35 horsepower.

After Gu Weijun came back from dinner, he found that Secretary Huang and Director Zhou were also there. The fat old man and Wu Zhonghua were excitedly holding the drawings and talking to them.

These few people didn't even have time to eat lunch, so they called two old masters from Shijingshan. One used an electric steel furnace to melt scrap steel and pig iron to make new ductile iron and gray cast iron according to the latest calculated ratio; Sand casting of a modified diesel engine design;

The result is very gratifying!

At night, the new pearlitic gray cast iron cylinder and ductile iron cast crankshaft and other parts have excellent performance after testing. The strength is about 240Mpa and the hardness is about 230HBS, which can fully meet the pressure resistance and pressure resistance of high-horsepower diesel engines of more than 35 horsepower. Large load, wear resistance, corrosion resistance and other properties!

Although the performance of each component has been tested individually, it still needs to be combined into a diesel engine to continue operating tests and fatigue tests!

However, both the fat old man and Secretary Huang and others were full of confidence in the expected test results. The fat old man is confident in the results because the performance of these materials has far exceeded the design requirements; Secretary Huang and others do it out of their trust in the fat old man!

These are world-class scientists!

Suddenly, the fat old man shouted to Gu Weijun: "Gu Weijun, call Li Youshan now! Then pick him up!"

Gu Weijun was stunned, "Isn't it too late now? Mr. Li is probably asleep!" After completing the performance test of the new material, it was already past 10 p.m.

"It's not too late! You tell him that his large-scale casting of a 2-ton hydraulic press is ready!" The fat old man said unhappily: "Besides, why should you sleep? You can sleep enough at once until you die!"

Gu Weijun was stunned, wasn't it? Is this old man so crazy?

The fat old man turned his head again and said excitedly to Secretary Huang and Director Zhou: "These two materials are very suitable for large castings. I redesigned the rolling mill before, and now I am stuck on this large casting. Now I have these two materials." , we can definitely trial-produce one and see the effect!"

"In addition, due to time constraints, only two cast iron materials were tested today. We have also designed several materials before with different mechanical properties! The theoretical properties of several cast iron materials are even higher than today's test materials!"

Director Zhou was so excited that he grabbed the fat old man's hand and held it tightly, "Scientist Qian! Are you serious?" As the director of Shijingshan Iron and Steel Plant, he knew very well that the country needed those large forgings! Among other things, the armor and main shafts of new tanks and aircraft

The fat old man nodded solemnly!

"Haha!" Director Zhou laughed loudly and ordered the secretary beside him: "Xiao Wang, go ask the cafeteria to prepare some dishes! I will celebrate with Professor Qian, Professor Wu, and the students later!"

Secretary Huang also continued: "Xiao Wang, remember to say one more thing, you must have good wine and good food!"

"If the canteen is out of stock, ask Gu Weijun to go to my house. I still have the meat and good wine I saved before the Chinese New Year! Forget it, Xiao Wang, go there!"

Secretary Huang saw that Gu Weijun was still standing there dumbly and didn't move. He stepped forward and kicked him, "Why are you still standing there? Why don't you hurry up and pick up Mr. Li Youshan!"

"Oh!" Gu Weijun finally broke away from his role as a bystander and hurriedly called Li Youshan first!

When Mr. Li Youshan heard about the large casting, he could be clearly heard on the other end of the phone, stamping his feet happily, and shouted into the phone: "Come and pick me up as quickly as possible!" Got it!" Gu Weijun hung up the phone, trotted to the jeep, started the engine, jumped in, stepped on the accelerator and headed straight for Tsinghua University!

Li Youshan had been waiting at the South Gate of Tsinghua University for a long time. When he saw Gu Weijun's jeep approaching, he opened the door and jumped in without waiting for it to stop, saying in a hurried tone, "Quick! Quick!"

Gu Weijun rolled his eyes secretly. After changing gears, he turned the steering wheel fiercely. The jeep made a semicircle, smoke was coming out from the butt of the car, and it was like a drifting effect! Press the accelerator to the bottom again and accelerate!

Without waiting for the car to stop, Li Youshan jumped out of the jeep, staggered into the test workshop, and shouted: "Where is it? Where is it?"

"No! This, and this!" The fat old man pointed proudly at the diesel engine that had begun running tests! There are also cast iron plates and iron pillars on the side for testing performance!

Li Youshan ran over and picked up the iron pillars and plates with his hands, knocked them against each other, listened to the buzzing sound, and asked the fat old man: "Old Qian, where are the performance test data? Give it to me quickly!"

Li Youshan took the performance report handed over by the student. When he saw the column of strength and hardness, he did not continue to look down. He slapped the fat old man's thigh and shouted excitedly: "Fuck! You old man, you are so stupid." Yes!"

"Haha! There is hope for large-scale castings of hydraulic presses!" Li Youshan, with disheveled hair and waving his hands, tears looming behind his glasses,

"Everyone is here! Let's go have a drink!" Director Zhou waved his hand! "Let's talk while drinking!"

As a later generation, Gu Weijun actually cannot empathize with the fat old man and Mr. Li at all! Because I have watched too many documentaries produced by great powers on CCTV [-] in later generations! Isn’t there a clip of a speech by the President of the United States?

What is covered under the American flag is "Zhenhua Heavy Industries" Made in China!

Although there is no empathy, it still cannot diminish Gu Weijun's admiration for these scientists! Without the hard work of this generation, how could we be proud and proud in a few decades!

Fortunately, Gu Weijun was present and forcefully stopped Mr. Li Youshan from asking for a drink, while everyone else was very drunk!

Director Zhou’s next operation made Gu Weijun call him awesome!

Director Zhou first called the Metallurgical Department to report, and then directly contacted Taiyuan Heavy Industry, Anshan Iron and Steel, Shenyang Machine Tool Factory and other factories to ask for new materials and large castings, come quickly!

After all the people from the brother factories came to see the performance of several cast iron materials, they said two phrases in unison: "Fuck!" "Awesome!"

Then they worked together to optimize the casting process at the Shijingshan Iron and Steel Plant. The fat old man and others followed the engineers and master workers every day to climb up and down the process, and they were so dry!

As for the diesel engine, only a few students and Gu Weijun are left to observe whether it is running normally. Wu Zhonghua's students paid more attention to these test machines than Gu Weijun. These diesel engines were related to their graduation thesis!

For the fat old man, Li Youshan and others, what diesel engine? Hasn't it been studied already? Besides, there is nothing interesting about a steel rolling mill and a [-]-ton hydraulic press.

And there is another thing worth mentioning after the development of this new material, that is, the fat old man’s hat has finally been taken off!

Originally, the fat old man wanted to push Gu Weijun out, because the fat old man felt that Gu Weijun's contribution would be greater in the research of new materials! However, Gu Weijun firmly opposed it and repeatedly emphasized to him: First, he just did the calculation work, which is not worth mentioning; second, he is still young and still in the learning stage, and it is not a good thing to push yourself out too early!

There is only one thing I have to do now, and that is to continue to cooperate with the research and calculations of the Fat Old Man and others, and to continue learning!

Secretary Huang and others also persuaded the fat old man to finally give up the idea.

The fat old man who took off his hat immediately resumed his position as deputy director of the Institute of Mechanics. It is worth mentioning that the director is: Qian Xuesen!

Oh, do I have a chance to meet Qian Xuesen!

So excited!
