Zhuang Qianding didn’t say much. Now that Yu Hua had given the answer, all he had to do was wait for Yu Hua to deliver the historic good news and achieve another ‘from 0 to 1’ breakthrough.
Everything lies in this.
Electroslag remelting is really important.
From the perspective of heavy weapons projects, this technology means that high-strength gun barrels can be manufactured and produced, pushing the entire project forward and bringing the Military Industry Bureau's weapons production level to a whole new level - independent production and manufacturing of heavy weapons.
From the perspective of the field of metallurgy, there is no doubt that electroslag remelting has epoch-making significance, and its influence is no less than that from the Bronze Age to the Iron Age, because this is the first time that human civilization has touched the field of refining high-purity metals and mastered it.
The significance of this technology is that it can promote the rapid development of materials science.
From the perspective of the base area, electroslag remelting not only means mastering the ability to independently produce cutting-edge gun steel materials, but also means that the last piece of the jigsaw puzzle in the industrial system framework of the base area has been completed. Since then, relying on electroslag steel with extremely excellent material properties
Or electroslag metal, the industrial system in the base area is its own without any restrictions!
From an aircraft carrier engine crankshaft weighing hundreds of tons to an aircraft rivet weighing as small as a gram, the industrial system in the base that has been freed from the shackles of materials will soon have substantial manufacturing capabilities!
Yes, that's it, it's really no exaggeration.
Throughout ancient and modern times, any technology that breaks through from 0 to 1 will receive extremely generous returns. This is the reward science gives to explorers.
Zhuang Qianding left, with a smile on his face and expectations in his eyes, and walked step by step towards the machinery manufacturing factory. The early morning sunshine enveloped him, and a shadow followed closely behind him. This shadow was very young, as if he was the same person ten years ago.
An ignorant young man with a dream of saving the country through industry.
The dream that has been dormant for ten years now has a ray of light.
The dream of saving the country, this is his dream of saving the country...
After giving the reply, Yu Hua did not waste any time and immediately left the Heavy Weapons Research Complex by car and went straight to Liushugou Iron and Steel Plant.
The reason why Professor Zhuang came to inquire today is nothing more than a matter of time.
Although the Japanese Fifth Division suffered heavy losses at Pingxingguan, in the final analysis, it still failed to change the overall strategically inferior situation of the Chinese defenders.
The powerful Japanese army could fail many times, but the defenders on the outer Great Wall defense line could only fail once without any chance of regret.
Soon after, Tojo Hideki's troops will capture Ruyue Pass and use it as a breakthrough point to tear apart the weak Great Wall defense line of the Shanxi-Sui Army, causing Yan Laoxi to flee back to Taiyuan in a hurry.
This is a war situation that cannot be changed.
As the Japanese invaders approach, time becomes increasingly urgent and the base area becomes urgent. This is normal.
After all, who doesn't want to have a heavy artillery force equipped with 105mm howitzers as soon as possible?
Soon, Yu Hua arrived at Liushugou Iron and Steel Plant, where the 1.5-ton single-column electroslag remelting test furnace project designed by him was settled.
The entire test furnace project was constructed in strict accordance with the finalized design plan. After more than 20 days of intensive construction, the main body of the test furnace was basically completed. The high-voltage power supply lines and transformers have been modified and laid. Only the operation console line connections and the water-cooled crystallizer system are left.
The installation and commissioning work has not yet been completed.
In addition, in order to improve transportation efficiency, a narrow-gauge railway was specially built in the test furnace plant to connect to the forging workshop, using a 12-horsepower single-cylinder diesel engine as traction power. After the electroslag steel ingots are smelted, they are immediately transported to the forging workshop for rough forging, and finally sent to the forging workshop.
Go to the machinery manufacturing plant for finishing.
Entering the factory, a semi-buried cigar-shaped special metallurgical furnace with a volume of about 5 cubic meters comes into view, and valuable equipment such as transformers and operating tables are clearly visible.
The main body of the test furnace is composed of upper and lower parts. The upper part belongs to the furnace control device. Next to it is a huge metal column covered with wires, which is responsible for controlling consumable electrodes and power supply. It can be moved freely. The lower part is the furnace body and base.
The internal structure of the furnace is almost the same as that of the mature electroslag furnace of later generations.
A single smelting of 5 tons of electroslag steel is enough to produce two 105mm gun barrels, or eight 40mm L56 gun barrels.
In order to keep up with the schedule and save time, the project adopted a two-shift system, with people working continuously without rest. When Yu Hua arrived at the test furnace building, he immediately went to work in person, took the baton from the person in charge of the on-site construction team, and began to install the water-cooled crystallizer.
.
The water-cooled crystallizer is one of the key equipment of the main body of the test furnace. Its main function is to crystallize and condense the molten metal liquid to form electroslag steel ingots.
This is the last level of the main body of the test furnace and cannot be ignored.
Instructions were given one by one, and the trucks were dispatched to lift the water-cooled crystallizer and various lines and pipe networks, and then the installation work was carefully carried out.
About five hours later, the water-cooled crystallizer was installed, and then the debugging process began. After two hours of rigorous debugging, it was confirmed that the operation was normal, and then it was accepted.
After completing the installation and commissioning procedures of the water-cooled crystallizer, Yu Hua carried out the final finishing work, connecting the lines between the operating table and the electroslag test furnace.
The atmosphere in the factory area is tense and serious. The construction team of dozens of people and the workers and soldiers are highly nervous and carry out operations with the highest efficiency.
At the same time, as Yu Hua announced that the electroslag test furnace project had entered a 48-hour countdown, the Military Industry Bureau entered a state of martial law, and all production units were notified to make corresponding preparations for the first smelting test.
Everyone is waiting for the final moment to arrive.
Time passes unconsciously.
"Squeak!" As the last steel screw between the console and the controller was tightened to the tightening strength standard, the electroslag test furnace completed all construction operations.
The picture seems to be frozen, and the world's first 5-ton single-column electroslag furnace was born.
"It's finally done. It took a total of twenty-five hours... After today, the industrial system in the base area will no longer have shackles and restrictions, and it can launch an impact on high-end fields. Compared with previous history, China has mastered electroslag furnace technology 23 years earlier.
, mastered the fluorine-free slag process forty-three years in advance." Yu Hua wiped the sweat from his forehead, took three steps back, stared at the electroslag test furnace that exuded an advanced atmosphere, his eyes were full of pride, and his heart was full of achievements.
feel.
Real pride, real satisfaction.
To be honest, there is nothing more intoxicating than creating a top-notch metallurgical technology with your own hands. This feeling is addictive and fascinating.
The last time he felt a great sense of achievement was when he succeeded in conquering the oxygen blowing furnace technology. Not long ago, the Red Star tractor project was successful, and Yu Hua didn't feel any excitement.
Now, he finally experienced this long-lost pleasure again.
This happiness belongs exclusively to scientific explorers!
In 1960, China designed and built the first industrial electroslag furnace.
In 1980, the fluorine-free slag process was born, which reduced the power consumption of electroslag furnaces by 50% and increased productivity by 100%.
This is the pace of development of high-end metallurgy in China in history. Since its birth, it has seriously lagged behind the development level of foreign metallurgy in the same period.
Today, things have turned around and history has changed.
