However, it is not the time to celebrate yet. The final assembly of the 100-level air separation equipment has been completed, and the three-hole oxygen lance equipment has also been installed. Next, the first smelting test of the oxygen top-blown converter will be carried out!
Open a door to the field of steel metallurgy and start the era of oxygen steelmaking in the base area!
At this moment, the moment that makes countless people excited or worried about it has finally arrived.
"Fellow soldiers and comrades, I announce that the final assembly of the test furnace has been officially completed. Now all personnel of the test furnace of Yulin Iron and Steel Plant obey my orders, and each unit will begin the final safety inspection!" Yu Hua took a deep breath, his eyes were clear, and his face was clear.
Calmly, with an indescribable aura from his posture like a majestic mountain, he turned around and looked around at several workers and commanders in the factory, solemnly announced that the final assembly of the test furnace had been successfully completed, and issued a new round of instructions.
Last safety check!
After this round of inspections, the crucial first smelting test will be carried out.
If the previous Yu's Seven Towers technology was a shot in the arm for the base area, saving the base area's weak economic situation that was always on the verge of collapse, then the oxygen top-blown converter is the marrow-cleansing pill in fantasy novels, washing away
Lead Hua, complete the transformation of the whole body and mind.
As my third work, the oxygen top-blown converter not only embodies my hard work, but also includes the hard work and knowledge of Professor Zhuang Qianding, the day and night hard work and efforts of tens of thousands of Red Army soldiers, and more than one million people before and after.
Financial investment, support from the entire organization.
This experiment must be successful, it must be successful!
I've been making swords for a long time, now let's test the edge.
This sword of steel is just like the sword of chemical industry in the past. If it is extremely sharp, it can cut through the steel industry building in the base area and fill the core gap in China's industrial system.
The eternal inheritance begins today.
At five o'clock in the morning, in the Sanchawan factory area, 500-watt searchlights flickered, like a beacon in the dark night, illuminating the entire factory area. Along with the orders given by the chief engineer of the steel plant, one dispatcher after another
Flags were waved and orders were conveyed quickly through semaphores. Immediately afterwards, each production team that had been trained to a qualified level quickly got busy and went to their respective posts to conduct the final round of safety inspections.
These production groups do not have very high academic qualifications and knowledge reserves. They all come from the Red Army. There are very few highly educated technical talents who were awarded junior high school or above in the Republic of China. Fortunately, as soldiers, they have strong execution ability. As long as they can give full play to their abilities
The function of the parts can ensure the normal operation of the first smelting test.
This is the advantage of relying on an organization. You don’t have to worry about the problems of experimental personnel, let alone worry about organizational coordination and personnel allocation, funds, material transportation, safety and other matters.
As the chief engineer, what Yu Hua has to do is to grasp the direction, tackle core problems, and ensure the success of the research and development of oxygen blowing furnace technology.
Time passed quickly, and the production teams that entered their respective work stations continued to send back news of the last round of safety inspections, which were passed through the dispatcher and summarized to Yu Hua.
Blast furnace area unit ready.
Coking area units are ready.
The power station is ready.
The fuel supply unit is ready.
Torpedo tanker transport unit ready.
The ten-ton truck is ready.
The air separation unit is ready.
Oxygen lance is ready.
The main body of the test furnace is ready.
The control room is ready.
When the safety inspection is completed, all production teams at the production station will be on standby.
Now, everyone is paying attention.
Whether it was the production teams inside the factory, or the workers and soldiers in the blast furnace area and coking area outside the factory, they all held their breaths, remained silent, and waited quietly.
The atmosphere is quiet and solemn.
All factory workers and soldiers in the Sanchawan area were waiting for the attack order from their superiors, as if they were about to enter the front line for fierce fighting.
Time, 5:29am at dawn on August 3rd.
"Add materials to the blast furnace and start the first smelting test of the test furnace!" Yu Hua has arrived at the main control room where he can observe the test furnace in all directions. He looked at his watch. The second hand returned to zero and the minute hand pointed to 5:30. He did not hesitate to look at the president behind him.
The dispatcher gives the order.
The chief dispatcher quickly waved the flag with both hands and conveyed instructions to all units in the field as quickly as possible. Two minutes later, all the production teams in the blast furnace area immediately put into production after receiving the order. Two soldiers at the raw material transportation station pressed the start switch, and two
The conveyor belt with a minimalist design style is powered on. Countless sinter and coke with shapes and sizes like glass beads rise rapidly on the conveyor belt, and then arrive at the funnel-like feed bin mouth and enter the interior of the medium-sized blast furnace.
In an instant, the high-power blower located under the blast furnace operates at full capacity to transport air. The hot blast stove quickly heats the air and then completes the ignition with the sprayed pulverized coal and gasoline.
Under the action of a steady stream of high-temperature air and flames, the fine coke as the main heat source suddenly changes, producing gas to assist combustion, and then burns violently, releasing a huge amount of heat, further increasing the internal temperature of the blast furnace.
Under the action of high temperature and the main flux limestone, tens of thousands of glass bead sintered iron ore first softens, then undergoes melting, and finally completely melts and transforms into the form of molten iron, and begins to drip downward to form a molten pool, showing an extremely dazzling orange color.
Red fire.
The blower continues to operate, and two minimalist conveyor belts transport raw materials at a speed of ten tons per hour to ensure the supply of raw materials.
This medium-sized blast furnace has a volume of 10 cubic meters and adopts a modern blast furnace core structure design. Although it looks simple and ordinary on the outside, it is very different from the small blast furnace of Liushugou Iron Works and all the blast furnaces in the Republic of China. It can continuously produce molten iron.
, the 24-hour molten iron output reaches 70 tons. Of course, not only this medium-sized blast furnace, but also the other two small blast furnaces can also continuously produce molten iron.
One medium-sized blast furnace, paired with two small blast furnaces, enables the designed daily output of molten iron to reach 120 tons. As for the actual output...
Emmm, if we can reach 30% of the designed production capacity within half a year, it will be enough to burn high.
Another thing to note is that although it is called a medium-sized blast furnace in name, in fact, this blast furnace with a volume of 10 cubic meters is not even a micro-blast furnace in Western European and American industrial countries, especially the Soviet Union and the United States. Other people's blast furnaces are often
Starting from 500 cubic meters, there are even super Big Macs with a volume of up to 1,000 cubic meters.
A medium-sized blast furnace of 10 cubic meters can only be called that in China. If it is placed outside, the volume must be increased by at least twenty times.
In the blast furnace area, as the last iron ore and coke enter the blast furnace, the raw material supply task is completed. An extremely complex smelting reaction process is going on in the furnace. The temperature has reached 1,450 degrees Celsius. The coke and gas continue to heat, and the limestone assists.
Melting, more and more iron ore turns into molten iron, and a fiery red molten pool is formed.
Around the medium-sized blast furnace, the commanders and dispatchers of the units in the blast furnace area stood with nervous and serious faces. All the workers and soldiers affiliated with the blast furnace area adjusted their status and made full preparations.
Each production team performs its duties and is prepared to do its job well.
Four hours later, the sky was already bright. Now, after continuous smelting, it was officially time to produce molten iron!
Below the taphole of a medium-sized blast furnace, a torpedo tank car with a volume of 1 cubic meter is waiting quietly. The inlet at the top of the tank is opened. A worker wearing a vest holds a steel drill and comes to the taphole seal of the blast furnace. He aligns the position and hammers hard
Poke open.
In an instant, a stream of fiery red, high-temperature molten iron like magma gushes out, enters the sight of the commander and the blast furnace dispatcher, flows rapidly down the trench, and enters the molten iron storage tank that serves as a transfer. The molten iron storage tank has a volume of three cubic meters.
meters, it can hold about 22 tons of molten iron at one time. The water outlet adopts a steel structure, mainly to improve the smelting efficiency and facilitate the delivery of molten iron to the torpedo tanker.
The first batch of molten iron of the Yulin Iron and Steel Plant project was born!
Seeing this scene, everyone was excited. However, as soldiers, they did not lose their minds. They suppressed the excitement in their hearts and continued to work at their posts. The commander issued different instructions to the molten iron storage tank team and the mud gun crew respectively.
At the command, the molten iron storage tank opened the water outlet, and the hot red molten iron entered the inside of the first torpedo tanker like water. The mud cannon crew controlled the mud cannon to enter the ready state. After the molten iron in the blast furnace was completely discharged, it quickly controlled the mud cannon machine to start the operation and seal the
Block the taphole of the blast furnace and enter the next round of smelting cycle.
At the same time, the blast furnace dispatcher quickly waved the flag and reported the situation to the main control room.
As the news of the first batch of molten iron came out, the spirits of everyone in each unit were lifted. Yu Hua also breathed a sigh of relief, with a look of anticipation in his eyes.
Once the molten iron is gone, will the molten steel be far behind?
Soon, the first torpedo tank car went through the slag removal process and set off with a full load of 7.3 tons of high-temperature molten iron. It left the blast furnace area via the narrow-gauge railway and drove more than 200 meters into the exclusive discharge port of the factory. The tilt angle of the torpedo tank car and the water inlet
It turns into a water outlet and slowly aims at the iron bucket commonly known as the iron bag located directly below.
The molten iron is poured into the iron bucket.
After a while, more than three thousand kilograms of molten iron was introduced into a small iron bucket. Sun Hong, the crane worker, felt a rush of heat in his face. With a calm expression, he steadily controlled the crane to lift the iron bucket from the molten iron area to the
Go away from the main body of the test furnace.
Under everyone's attention, the iron bucket crossed the last distance and came to the tilted converter mouth. It lowered the height, raised the tail of the bucket, and aligned the bucket mouth with the converter mouth. The high-temperature molten iron that gathered countless eyes and became the focus was poured into the container.
There are various kinds of scrap steel inside the converter.
