Yanyu Highway is one of the main arteries of the base area. Although it can meet the conditions for traffic, the road condition is not ideal. The land base is mainly dirt, and a few road sections are gravel. There are potholes everywhere along the way, which makes him suffer from back pain.
When the Yushen Highway and New Yanma Highway projects are completed, the construction of the Yanyu Highway will be put on the agenda.
Lu Junyu asked: "Chief, should we go back to the headquarters first, or go to Liushugou?"
"First go to Liushugou Machinery Manufacturing Factory to see how the 12-horsepower single-cylinder diesel engine looks like." Yu Hua said. There is only one core technology of the Red Star tractor project, and that is the powertrain-12-horsepower single-cylinder diesel engine.
The design plan for the 12-horsepower single-cylinder diesel engine was jointly finalized and confirmed by Professor Yu Hua and Zhuang Qianding. According to the plan, it is currently in the prototype trial production stage.
As long as the powertrain is solved, the entire Red Star tractor project will be half successful. After all, this is the most technical part, such as the transmission system, cargo box, brake clutch, suspension and other sub-structures, all of which use mechanical parts. There is no technology at all.
content.
Speeding on the two-lane Xinyan-Ma Highway, more than 20 minutes later, the entire Dodge truck arrived at Liushugou, entered the industrial area, and finally stopped steadily in front of the newly built machinery manufacturing plant based on the arsenal.
Get off the car and stand still.
A factory building with a red brick and cement structure came into view. It was two stories high. Two Red Army soldiers with loaded guns stood at the door. A plaque of Yancheng Machinery Manufacturing Factory hung next to it. A familiar diesel generator set came from the generator room not far away.
There is no sound of work, and power is continuously and stably supplied to the entire factory.
This is now the heart of Liushugou - the machinery manufacturing factory.
In terms of status and importance, the newly built machinery manufacturing plant ranks first in the Liushugou Industrial Zone, and even the arsenal next door cannot compare with it.
As for the reason, it is very simple. Basically all the weapons and equipment parts in Liushugou must be processed by the machinery manufacturing factory.
Nowadays, in order to protect the extremely precious machining equipment of the machinery manufacturing plant from being destroyed by spies, not only a regiment of troops is stationed outside the machinery manufacturing plant, but a dedicated armed security office is also established in the factory area, and a platoon of troops is deployed to strengthen the protection.
This is a serious defense with heavy troops.
Through the gate, Yu Hua found that the factory was basically in a state of one post every ten steps and one sentry every five steps. He nodded with satisfaction, then stepped forward, entered the factory area after being verified by two sentries, and headed for the workshop.
The interior of the factory is divided into mechanical processing area, finished product area, raw material area, warehouse and office area according to purpose. Passing through the raw material area where various parts and raw materials are piled up, Yu Hua came to the noisy mechanical processing area and observed quietly like a bystander.
The sounds of machine tools running and performing metal processing complement each other.
The fierce friction between metal and metal plays an industrial symphony unique to Yancheng. On the one hand, it belongs to the world's top mechanical processing equipment, and on the other hand, it comes from the high-quality steel produced by the epoch-making oxygen top-blown converter. It is melodious and beautiful.
The turning shop is in a busy state, with five lathes performing their duties and processing mortar barrels in an orderly manner. There are seven or eight standard barrels that have been processed on the ground.
After watching for a while, Yu Hua said nothing and walked forward to the milling workshop.
At this time, Professor Zhuang's figure appeared in sight, standing in front of the GROB semi-automatic gantry milling console. Zhuang Qianding controlled the high-speed running milling head to contact the prototype cylinder, and wire-like metal debris continued to emerge.
Out, the prototype cylinder has been formed.
Seeing this, Yu Hua quietly entered the workshop, just like he did in the Tsinghua Park Engineering Laboratory, standing quietly by the side, quietly observing and studying.
External milling, spot holes, drilling, cylinder precision boring, plus repeated measurements and corrections... There is no doubt that the entire milling process is extremely cumbersome.
Time passed, and after about an hour, the sound of the semi-automatic gantry milling machine disappeared, and the prototype cylinder on the workbench was silver-white, exuding metallic luster, with extremely low surface roughness, revealing unparalleled mechanical beauty like a work of art.
The prototype cylinder is manufactured!
"Huh... prepare the engine assembly work immediately, and strive to complete the prototype assembly within today." The exhausted Zhuang Qianding turned off the semi-automatic gantry mill, wiped the sweat from his forehead, and while adjusting his breathing, issued instructions to the five members of the milling team
instruction.
The important parts of the diesel engine, such as the crankshaft, crank connecting rod, piston and cylinder head, have been processed. After the cylinder block, which is the last part, has been processed, it is time to assemble the prototype.
In the past few days, Zhuang Qianding had hardly rested in order to build a prototype as soon as possible, and his body and mind had reached their limits.
"Yes!" The five members of the milling team nodded in unison and immediately became busy, carefully carrying the cylinder weighing dozens of kilograms and leaving the workshop.
Zhuang Qianding was a little tired and was about to sit down and rest. Suddenly, out of the corner of his eye, he caught sight of Yu Hua standing on the right. He was stunned for a moment, with a look of surprise on his face: "Why are you back? Wait, could it be that...
"
"Professor, I have brought you good news. The trial production has been successfully passed. This is the trial production report."
With a look of respect on his face, Yu Hua stepped forward to inform him of the situation, then took out the trial production report and handed it to Zhuang Qianding, saying softly: "We succeeded."
It was successful, yes, it took more than half a year, from the initial conception and planning to the completion of 24-hour trial production in the test furnace, and it was finally successful.
"The actual output of steel in 24 hours is 94.65 tons, the average output of a single furnace is 2.01 tons, and the output per hour is 3.94 tons. The ratio to the designed output is 98.5%... Good, good, very good. I never thought that one day we in China would really develop a
The steel smelting technology is more advanced than that of Western countries. Yu Hua, you are now qualified to call yourself the father of the oxygen top-blown converter." Zhuang Qianding was moved when he heard this, and quickly took the paper report. When the content of the report came into view, the entire
The person then became excited, his words trembled slightly, his inner emotions surged out like a bursting dam, and he shouted three times in a row.
The father of oxygen top-blown converter!
In terms of Yu Hua's technical contributions, he is fully worthy of this title. No one in the world is more qualified to deserve this honor than Yu Hua, not even Besmer, who originally proposed the idea of oxygen steelmaking.
Besmer only proposed the idea of oxygen steelmaking, but it is almost unimaginable how difficult it is to transform oxygen steelmaking from a pioneering idea into a reality and complete the first industrial application.
Look at how terrible the oxygen top-blown converter steelmaking technology is?
The actual output of steel in 24 hours was as high as 95.65 tons!
This is a converter with a smelting mass of only 2 tons!
What is the difference between a 2-ton converter and a hundreds-ton open-hearth furnace?
A gap of dozens or even hundreds of times.
It must be said that Yu Hua handed over an unprecedented answer sheet.
Surpassing Britain and the United States, leading the world, and doing so quietly.
"Professor, these are just empty names to me and are not important. If exposed, it will plunge China into a catastrophe." Yu Hua smiled and said with a natural expression: "Professor, before I lose the ability to protect myself, I
We are not planning to release any papers or news about oxygen top-blown converter technology to the outside world.”
Although the oxygen top-blown converter steelmaking process is good, it is not something China can afford today.
Once the news leaks, it will definitely trigger an unprecedented crisis, and almost all industrial countries in the world will put pressure on it, including the Soviet Union, which is regarded as the big brother.
A steelmaking process concept proposed by Besmer 150 years ago, and a cutting-edge metallurgical technology that has completed its first industrial application, the two are completely different concepts.
Those tigers, leopards and jackals will use all means to rob, literally all means!
The so-called father of the oxygen top-blown converter is just a false name. Although Yu Hua needs fame to increase his authority, he will not be stupid in this matter.
"Okay, I understand, but you have to understand that if someone develops oxygen top-blown converter technology before you do, then this honor will be lost." Zhuang Qianding immediately understood the meaning of Yu Hua's words and took a deep breath.
Taking a breath, with a solemn and solemn face, he silently regarded the oxygen blowing furnace technology as the highest secret and would never mention it to anyone on any occasion.
Academics have no boundaries, but technology has boundaries.
This top technology, which can determine the fate of the country, certainly cannot fall into the hands of the Japanese invaders and the West. But here is the problem. If Yu Hua does not announce it now, then when someone announces the registered patent, the honor of the father of the oxygen top-blown converter will no longer belong to him.
Yu Hua.
This has always been the case in academia. Only by publishing research and development results and registering patents are the real winners.
"It's not important."
Yu Hua nodded and changed the topic to concern about the Red Star tractor project: "Professor, how is the situation of the single-cylinder diesel engine? At present, the transportation capacity problem has become our biggest shortcoming. Whether it is highway construction or industrial raw material demand, they are all limited by
There is a transportation capacity problem. Yulin Steel Plant has a daily transportation capacity quota of twenty tons, which is only enough to meet the needs of five tons of steel smelting."
"You came just in time. All parts of the first prototype of the 12-horsepower single-cylinder diesel engine have been processed and are in the assembly stage. I happen to be short of people here." Zhuang Qianding said with a smile after hearing this.
"Students understand." Yu Hua smiled.
Zhuang Qianding and Yu Hua turned around and left the milling workshop and headed to the finished product area, where the 12-horsepower single-cylinder diesel engine prototype was being assembled.
Arriving at the finished product area, the prototype cylinder block that was previously like a work of art was placed in the center of the assembly table, and a series of engine parts, crankshafts, pistons, cylinder heads, etc. were arranged in order on the left and right sides.
"Have you forgotten the engine design drawings?"
Zhuang Qianding stood in front of the workbench, picked up a cast iron wrench and handed it to Yu Hua, saying: "You design the engine, and you assemble it."
"Of course I haven't forgotten."
Hearing these words, Yu Hua, the designer of the 12-horsepower single-cylinder diesel engine, smiled slightly, took the cast iron wrench, and started working in a familiar way, assembling the engine parts in order.
Crankshaft, timing gear, piston connecting rod group, cylinder head, oil pump, water tank, fuel tank, plus the most classic big flywheel.
In more than 20 minutes, with the last-minute tightening of the nuts, the 12-horsepower single-cylinder diesel engine, the power core of the classic walking tractor that would shuttle through the streets and fields for generations to come, was born.
