Chapter 326 The first furnace of molten iron!
However, now is not the time to celebrate. The [-]-level air separation plant has completed the final assembly, 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 iron and steel metallurgy, and open the era of oxygen steelmaking that belongs to the base area!
At this moment, the moment that makes countless people excited or worried about it has finally come.

"Soldiers and comrades, I announce that the final assembly of the test furnace has officially been completed. Now all the personnel of the test furnace of Yulin Iron and Steel Plant obey my order, and each unit will start the last safety inspection!" Yu Hua took a deep breath, his eyes were clear and his face was clear. Calmly, with an inexplicable aura like a majestic mountain, he turned around and looked around at several workers and commanders in the factory building. He announced the successful completion of the final assembly of the test furnace and issued a new round of instructions.

One last security check!
After this round of inspections, the crucial first smelting test will take place.

If the previous Yu's Seven Pagodas technology is a shot in the arm for the base area, it can save the economic situation of the base area which is weak and is always on the verge of collapse, then the oxygen top blowing converter is the cleansing pill in fantasy novels. Lead Hua, complete the transformation of the whole body.

As my third work, the oxygen top-blown converter not only condenses my own hard work, but also includes the hard work and knowledge of Professor Zhuang Qianding, the hard work and hard work of tens of thousands of Red Army soldiers day and night, and more than 100 million funds. Input, support from the entire organization.

This test must be successful, absolutely must be successful!

It's been a long time since I've been casting swords. Now, let's try the edge.

This steel sword, just like the former chemical sword, if it is extremely sharp, it can cut out the steel industry building of the base area and fill the vacancy at the core of the Chinese industrial system.

The foundation of the world begins today.

At five o'clock in the morning, in the Sanchawan factory area, the [-]-watt searchlights flickered like a beacon in the dark night, illuminating the entire factory area, accompanied by the order of the chief engineer of the steel factory, a dispatcher. The flags were waved, and orders were quickly conveyed through semaphores. Then, one by one, the production teams that had been trained to a qualified level quickly got busy and went to their respective positions for the final round of safety inspections.

These production teams do not have very high education and knowledge reserves, and all come from the Red Army. There are very few technical talents with high education and above. Fortunately, as soldiers, they have strong execution ability, as long as they can give full play to their own skills The function of the parts can ensure the normal operation of the first smelting test.

This is the advantage of being backed by the organization. You don't have to worry about the problem of test personnel, let alone distract your energy from managing organization coordination and personnel allocation, and worrying about funds, material transportation, and safety.

As the chief engineer Yu Hua, what he has to do is to grasp the direction, tackle the core, and ensure the successful development of oxygen blowing furnace technology.

Time passed, and soon, the production teams who entered their respective jobs kept sending back the news of the last round of safety inspections, which were passed on by the dispatcher and summarized to Yu Hua.

The blast furnace area unit is ready.

The coking zone unit is ready.

The power station is ready.

The fuel supply unit is ready.

The torpedo tanker transport unit is ready.

The ten-ton truck is ready.

The empty extension is ready.

Oxygen lance is ready.

The main body of the test furnace is ready.

The main control room is ready.

After the safety inspection is over, all production teams in the production positions are all on standby.

Now, all eyes are on it.

Whether it was the production teams in the workshop, or the workers and soldiers in the blast furnace area and coking area outside the workshop, they all held their breaths, kept silent, and waited quietly.

The atmosphere was quiet and solemn.

The workers and soldiers of the whole factory in the Sanchawan area, as if they were about to enter a fierce battle on the front line, were waiting for an attack order from their superiors.

Time, 5:29 am on August [-]rd.

"The blast furnace is charged, and the first smelting test of the test furnace begins!" Yu Hua has come to the main control room where he can observe the test furnace in all directions. He looked at his watch, the second hand resets to zero, and the minute hand points to 5:30. 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. After receiving the order, all production teams in the blast furnace area immediately put into production. The conveyor belt with a minimalist design style is powered on and running, and countless sintered ore and coke in the shape and size of glass beads rise rapidly on the conveyor belt, and then arrive at the feeding bin like a funnel, and enter the medium-sized blast furnace.

In a blink of an eye, the high-power blower located below the blast furnace runs at full force to deliver air, and the hot blast stove rapidly heats the air, and then ignites with the sprayed pulverized coal and gasoline.

Under the continuous action of high-temperature air and flame, the fine coke, which is the main heat source, changes suddenly, produces gas to support combustion, and then burns violently, releasing huge amounts of heat, further increasing the internal temperature of the blast furnace.

Under the action of high temperature and the main flux of limestone, tens of thousands of glass beads sintered iron ore first softened, then melted, and finally completely melted and transformed into molten iron, which began to drip downward to form a molten pool, showing an extremely dazzling orange. Red flare.

The blower keeps running, and the 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 is designed with a modern blast furnace core structure. Although it looks simple and ordinary in appearance, it is very different from the small blast furnaces in Liushugou Iron Works and all blast furnaces in the Republic of China. It can continuously produce molten iron , The 24-hour molten iron production reached [-] tons. Of course, not only this medium-sized blast furnace, but also two other small blast furnaces can also continuously produce molten iron.

A medium-sized blast furnace, with two small blast furnaces, makes the designed daily output of molten iron reach 120 tons. As for the actual output...

Emmm, if you can reach 30% of the designed production capacity within half a year, it is enough to burn high incense.

Another point to note is that although it is called a medium-sized blast furnace in the name, in fact, this blast furnace with a volume of 10 cubic meters is placed in western European and American industrial countries, especially the Soviet Union and the United States. It is not even a miniature blast furnace. Starting at [-] cubic meters, there are even super giants with a volume of up to [-] 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 [-] times.

In the blast furnace area, with the last batch of iron ore and coke entering the blast furnace, the raw material supply task is completed, and the furnace is undergoing an extremely complicated smelting reaction process, and the temperature has reached 450 degrees Celsius. More and more iron ore is turned into molten iron, and a fiery red molten pool is formed.

Around the medium-sized blast furnace, the unit commanders and dispatchers in the blast furnace area stood with nervous and serious faces. All the workers and soldiers affiliated to the blast furnace area adjusted their status and prepared with all their might.

Each production team performs its own duties and is ready to do its job well.

Four hours later, the sky is already bright, and now, after continuous continuous smelting, the time for the official production of molten iron has arrived!
Below the tap hole of the medium-sized blast furnace, a torpedo truck with a volume of 1 cubic meter waited quietly. The entrance at the top of the tank was opened. A worker in a vest held a steel drill and came to the tap hole of the blast furnace. Poke open.

In an instant, a fiery red hot molten iron gushing out like magma, entered the sight of the commander and the blast furnace dispatcher, quickly flowed down the trench, and entered the molten iron storage pool that served as a transfer. The volume of the molten iron storage pool was three cubic meters meters, can be about 22 tons of molten iron at a time, and the water outlet adopts a steel structure, mainly to improve the smelting efficiency and facilitate the transportation of molten iron to the torpedo tanker.

The first furnace of molten iron in the Yulin Iron and Steel Plant project was born!
Seeing this scene, everyone was excited, but as soldiers, everyone did not lose their minds. They resisted the excitement in their hearts and continued to work at their posts. The commander issued different orders to the molten iron storage tank group and the mud gun group order, the molten iron storage tank opened the nozzle, and the fiery red molten iron entered the first torpedo tanker like a water flow. The mud gun unit controlled the mud gun to enter the ready state. Block the blast furnace tap hole 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.

With the news that the first batch of molten iron was released, everyone in each unit was invigorated, and Yu Hua was also relieved, with a look of anticipation in his eyes.

With molten iron, will molten steel be far behind?
Soon, the first torpedo tanker set off with a full load of 7.3 tons of high-temperature molten iron after going through the slag removal process, left the blast furnace area via the narrow-gauge railway, and drove more than 200 meters into the exclusive discharge port of the plant. The water outlet is slowly aimed at the iron bucket, commonly known as the iron bag, located directly below.

The molten iron is poured into the iron barrel.

In a short while, more than 3000 jin of molten iron was introduced into the small iron drum. Sun Hong, the crane worker, felt a rush of heat. The main body of the furnace is gone.

Under everyone's attention, the ladle crossed the last distance and came to the mouth of the converter, which was in a tilted state, lowered the height, raised the tail of the barrel, and aimed the mouth of the barrel at the mouth of the converter. There are various types of scrap inside the converter.
