Ever since the convoy set off, Yu Hua, who was so tired that he felt extremely tired, lay down in the cargo box of the Dodge truck, squinting peacefully on the soft thatch, not worried about being intercepted by bandits or assassinated by agents.
There is no other reason than the strong security force.
Not to mention the elite headquarters security company, which has experienced hundreds of battles, just strengthening the artillery platoon is enough to make any bandit or regular army feel what firepower is.
Four high-quality sixty-zero mortars, a shell carrying capacity of up to three bases, plus four Czech-style light machine guns and Liushugou-made M24 hand grenades whose performance is no less than that of authentic German goods.
What is firepower?
That’s it!
What is the concept of three shell bases?
According to the latest "Basic Regulations on Troop Ammunition" compiled by the headquarters based on the performance parameters of the Type 37 60mm mortar, the transportation capacity level of grassroots troops and the production capacity of the Military Industry Bureau, the base standard for a Type 37 mortar is 30 rounds.
And increasing the base number of three artillery shells in the mortar battery means reaching as many as 90 rounds!
One gun has ninety shells, and four guns have a total of 360 shells.
This number may not seem like much, but for the Red Army, whose number of artillery shells hovers in double digits and single digits all year round, it is really unimaginably rich.
To be fair, in order to ensure the smooth delivery of core equipment to Yulin, the Military Industry Bureau has spent a lot of money this time. With the headquarters security company and the reinforced artillery platoon, let alone bandits, even a regiment from Zhongzheng can occupy three points.
Firepower advantage.
With such a strong security force around you, why worry about not sleeping well?
There was no dreaming, a complete deep sleep. Yu Hua slept for a full ten hours. When he woke up, he felt refreshed and energetic, and his whole body and mind were restored to their best condition.
"Chief, we are back." Lu Junyu reminded Yu Hua when he saw him waking up and handed him a kettle and dry food.
Yu Hua nodded, took the kettle, started chewing the dried meat in his right hand, looking at the scenery in front of him, and said softly: "It's so beautiful... After preparing for so long, our moment is finally coming."
Yes, in more than thirty hours, it will be a moment that belongs to 'us', a moment that belongs to China...
The motorcade arrived at its destination smoothly and smoothly. Yulin City, like a pearl on a fortress, came into view. Thousands of red clouds enveloped this vast and lonely town in northern Shaanxi.
Red, dazzling and full of hope, has become the main color of this world.
Along the newly repaired and widened gravel road, the transport convoy was bathed in the sunset, slowly arriving at the Sanchawan area where heavy troops were stationed, and arrived at the steel plant.
With the arrival of the core unit of the air separation equipment and the three-hole oxygen lance, Yu Hua, as the first person in charge of the oxygen top-blown converter project, immediately issued the order for the final assembly of the test furnace without wasting time.
In an instant, the Yulin Iron and Steel Plant test furnace was activated like a machine and entered operation. One after another, Red Army technicians and workers who had received theoretical training entered their respective positions and worked according to the standard plan formulated for the first smelting test.
The power supply station of the steel plant started the diesel generator set to output electricity and supply it to the entire plant. The ten-ton truck lifted the three core units, each with a net weight of several hundred kilograms, to the predetermined assembly area in sequence. Yu Hua then personally came on stage to cooperate with this trip.
The assembly team is jointly responsible for the final assembly.
The final assembly is undoubtedly one of the most technically difficult parts. The three core units must be accurately connected, and the assembly accuracy must reach more than 95% of the theoretical accuracy to be considered qualified. The same goes for the three-hole oxygen lance assembly.
Accuracy and minimizing errors caused by human factors are the basic requirements for equipment assembly.
When the core equipment of the test furnace is being finalized, all basic supporting facilities areas of the steel plant are in a state of preparation. The team of workers in the blast furnace area conduct strict safety inspections on the blast furnace main body and combustion pipes and other production equipment in accordance with regulations to prepare for the smelting of molten iron.
To prepare, two one-cubic-volume torpedo tank cars passed through the 200-meter-long narrow-gauge railway, entered the blast furnace area under the traction of motors, and waited at the water outlet of the medium-sized blast furnace.
The coking area is not very busy. After all, the coke refining work has been going on since the completion of the construction, providing the most basic coke for the test furnace to conduct various metallurgical tests and steel smelting.
The sky gradually darkens, and the bright stars appear in the sky.
Throughout the Sanchawan factory, everyone was sweating like rain, with fire burning in their hearts, working tirelessly like machines, not caring about the time that passed quietly.
A few hours later, all safety inspections in the blast furnace area were completed and all inspection results passed. The sintering workshop was declared to be operating at full capacity and continued to produce sinter mixed with limestone. Reports continued to spring up like bamboo shoots after a rain, and finally converged on Yu Hua.
, for decision-making.
However, Yu Hua didn't care about the preparations for the factory. He focused all his energy on the turboexpander in front of him that weighed more than 800 kilograms.
The expansion unit is connected to the air cooling tower and the condensing evaporator. Its main function is to adiabatically expand the high-temperature compressed air to generate sufficient cooling capacity. From the perspective of the importance of the equipment structure, the expansion unit is the same as the compressor unit. The latter belongs to the heart, and the former belongs to the lungs.
department.
What Yu Hua has to do is to install this extremely high-tech and crucial 'lung' exactly where it should be.
The assembly work in the factory continued, and Yu Hua continued to cooperate with Yu Hua in starting, reorganizing, and controlling the vehicle. Time passed slowly by one minute, until eleven o'clock in the night. After six hours of busy work, with the last screw tightened in place, the air separation
The first good news finally came out about the final assembly of the core unit of the equipment. The expansion unit was assembled and accurately connected.
Everything is difficult at the beginning. With the most difficult assembly of the expansion unit completed, we are only one step away from the birth of the world's first 100-level air separation equipment.
The steelmaking principle of oxygen top-blown converter can be seen all over the world, and even a third-rate metallurgist can explain it. However, without the core 100-level air separation equipment as the oxygen supply basis, wanting to use oxygen to make steel is nothing more than a dream.
.
This is the prerequisite technology that must be turned on to realize oxygen steelmaking.
Hour after hour gradually passed, all the preparations for the first smelting test have been completed in the basic supporting facilities areas of the Sanchawan factory. In the factory, the atmosphere was quiet and serious. Workers and Red Army soldiers stared at the metal giant like a hill.
The beast, an air separation equipment with a body of two meters wide and four meters long, has come into everyone's sight.
Time passed quietly for fifteen hours, and a full thirty-two hours had passed since the initial forty-eight-hour countdown.
"squeak!"
A slight sound of metal friction was heard. Yu Hua stood in front of the compressor unit and tightened the last steel screw with an adjustable wrench. Soon, the screw was tightened to the standard.
Time freezes. At this moment, the world's first 100-level air separation equipment was born.
"It was finally completed. It took a total of fifteen hours and did not exceed expectations... The world's first 100-level air separation equipment was born. In a sense, this is a milestone in the field of oxygen production and a historic moment.
"The most advanced and cutting-edge air separation equipment in the world was born in the least industrially developed region on earth." Yu Hua stepped back three meters, wiped the sweat from his forehead, his eyes were reddish, and he stared at the big machine in front of him, feeling a sense of accomplishment in his heart.
Full.
The sense of accomplishment is really overwhelming. There is no system help. I rely entirely on the knowledge in my head and my hands. I have to say that this feeling of creating a cutting-edge technology step by step is really great.
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!
