Chapter 386 The first electroslag steel ingot was born!
Time passed quietly, and the fish belly turned white in the distance.
Big cave dwelling.
The boss, who was wearing a coat, walked back and forth, looking up at the door from time to time, with eagerness and expectation intertwined in his eyes. He raised his right hand and looked at the time. When he saw that there was still no movement, he shook his head and started walking again.
"I said, boss, don't be so anxious. I can't help but see flowers when I walk here and there. You have to eat beforehand, so you don't go hungry." A joking voice came from the door of the cave, and the figure looked at it.
He looked like a boss, holding a pottery bowl filled with porridge, and said while eating.
"I think the boss can't eat it for the time being, so we might as well eat it first." The elegant man also held the pottery bowl and joked.
"Desheng, you must have an appetite. I really can't eat it." When the boss heard the two people's banter, he couldn't help but shake his head and sigh. He sat down next to the stone mill, took out a cigarette and lit it: "It's so important today.
It’s really important. The success of the smelting test means that our army will now have the ability to independently manufacture heavy artillery, and it means that we will no longer have to hide in Tibet..."
Heavy artillery is a well-deserved strategic weapon in this era, and the significance of independently manufacturing heavy artillery is that they have a foundation to compete in the world!
The days of hiding in Tibet are gone forever.
The first smelting test being carried out at Liushugou Iron and Steel Plant is of great importance to the organization and the troops.
"Be sure to have dinner in advance. After dinner, we are waiting here for the good news. I believe that this young man Yu Hua will bring us good news." The figure looked calm, with confidence in his brows, and took a bite with his chopsticks.
Porridge, said seriously: "Boss, from a scientific point of view, if you don't trust me, don't you still trust Professor Yu Hua and Zhuang?"
"Since Professor Zhuang and Yu Hua arrived at the base area, our life seems to have changed in an instant, which makes me, a person who is full of confidence in the future, find it incredible..." The elegant man nodded, with emotion in his eyes: "Science is really true.
It can change everything."
The former base area had no light industry, no heavy industry, and no military industry. It was a typical three-no zone.
The light and heavy industries are completely zero, and nothing can be manufactured. The level and scale of the military industry are at their most primitive levels. The arsenal can only produce low-quality grenades filled with black powder, the kind that explode with two or three lobes.
What now?
The light industry can produce clothing, cigarettes, salt, glass, ceramics, etc., the heavy industry can produce motors, diesel engines, bearings, turbines, tractors, the chemical industry includes three acids and two bases and various types of high-quality explosives, and the military industry has achieved
The targets independently manufactured by the light weapons system can produce 60mm mortars, medium-sized rifles and various bullet grenades.
The days in the base area changed instantly after Professor Zhuang and Yu Hua arrived at the base area, becoming better and better and more and more incredible.
"I understand this. It is precisely because of the changes in the base area and the prosperity of the base area that I can't calm down. Soon, Chiang Kai-shek will discover the changes in the base area, and the Japanese will also discover what will happen by then.
it goes without saying."
The boss took a puff of his home-made cigarette and said in a deep voice: "I am like a wealthy landlord now. I urgently need a big knife to drive away those wolves. With heavy artillery and heavy artillery troops, we can hold on to these hard-won things.
"
"However, Desheng, you are right. No matter how anxious I am, I can't do anything. Going to the steel plant rashly will still affect the experiment."
"Have a meal!"
"That's right."
Desheng smiled and nodded: "Respect science and let's just do our job well."
The whole person was holding a bowl and eating porridge while looking at the light reflected in the ravine in the southeast. It was the light of hope for defeating the Japanese invaders and... the dawn of saving China.
Studying medicine cannot save China, and teaching cannot save China. Only cannons can measure the territory of China, smash the three mountains that are pressing on the Chinese nation, and resist the invaders.
…
The night is silent, and the morning light gradually breaks the shackles of the night.
On the horizon, the sun rises in the east, covering the heaven and earth with its light.
Inside the Liushugou Iron and Steel Plant, the electroslag furnace workshop.
"Zhi!" The sound of high-frequency current from the operation of electrical equipment resounded all around, and a steady stream of electric energy was continuously input to keep the test furnace operating at a rated power of 380KV. The temperature of the space around the workshop was quite high, and the test personnel at each position were sweating profusely.
state of exhaustion.
At this time, the clock on the wall had quietly pointed to nine o'clock in the morning.
As the scheduled time arrived, everyone present cheered up and turned their attention to Yu Hua, who had been sitting in the middle for five hours.
"Operation console, report equipment operating data." Yu Hua, who was highly concentrated, immediately raised his watch to check the time, checked it with the workshop clock, and then issued instructions to the console after confirming that it was correct.
"Report, voltage is 58V, current is 6500A, rated power is 380KV, real-time power consumption is 1560 kWh/ton, and the estimated average remelting rate is 300 kilograms per hour." After receiving the instruction, the young operator methodically gave a series of equipment operating parameters: "Currently
It has been running for five hours and the estimated remelting capacity is 1,500 kilograms."
At the same time, another operator held a pencil and recorded the operating parameters as quickly as possible for data backup.
"Control console, raise the height of the electrode chuck by 50 centimeters, cancel the loop, and maintain the current state of the crystallizer." Yu Hua took a deep breath, moved his somewhat stiff shoulders slightly, stared at the main body of the fiery red test furnace that released billowing hot air, and said in a serious voice.
Issue instructions.
The young operator immediately followed the instructions and quickly controlled the electrode chuck. The chief dispatcher waved a flag and conveyed instructions to the crystallizer unit.
"Buzz!"
In an instant, the electrode chuck slowly rose under the action of the hydraulic device, and the red and hot electrode steel ingot slowly rose. The lower end of the steel ingot was in a molten state, and red liquid molten steel continued to drip. As the electrode steel ingot left the molten pool, the current circuit
Then disconnect.
A billowing heat wave erupts from the main body of the test furnace, and the operation of the crystallizer is maintained to ensure that the molten metal under the molten pool crystallizes and condenses at the fastest speed to obtain steel with the highest purity.
The changes in the workshop suddenly attracted the attention of everyone around. Looking at the slowly rising electrode chuck, everyone understood that the most important moment had come.
At this moment, a raw electroslag steel ingot with a thickness of 280 mm has been formed, with a height of about 5 meters and a total mass of 1,500 kg.
Of course, from a strict perspective, the original electroslag steel ingots in the current test furnace cannot be called 'electroslag steel' for the time being. Only through strict metallographic testing and element content testing can the internal metallographic structure and composition be confirmed.
After the content reaches the standard of electroslag steel, it can be officially called electroslag steel.
"Stop the main pump of the crystallizer, tilt the main body of the test furnace 90° to the right, and take out the steel ingot." The smelting mathematical model in his mind was running at high speed. After the crystallizer cooled and crystallized the last molten metal, Yu Hua gave the order without hesitation.
When the order came out, all units immediately executed it. The main pump of the crystallizer was shut down, and the main body of the test furnace was tilted. When the angle of the furnace mouth reached 90 degrees, two soldiers from the steel collection team appeared, wearing the simplest heat insulation suits.
, using a metal chuck connected to the crane, close to the extremely hot main body of the test furnace, and using the metal chuck to lock the red original electroslag steel ingot.
"Buzz!" The vehicle slowly moved backwards. The two soldiers endured the scorching heat and tightly controlled the metal chuck to take out the electroslag steel ingot weighing 5 tons from the test furnace.
"Boom!"
The fiery red electroslag steel ingot fell and came into close contact with the metal transport flatbed truck prepared below, making a deafening sound of metal impact.
It's dull, thick, surging and powerful.
The scene freezes, and the world's first electroslag steel ingot is born.
