Chapter 195 Advanced Steel Equipment
Yes, this is the demeanor of steel warriors, and the brilliant group portrait of the new steel workers!
At this moment, all of this has been deeply imprinted in Li Yang's mind.
Looking around, there are mountains and seas of books. Every book, every formula, every chart has become extremely familiar and vivid.
They have become Li Yang's strategic weapons, helping him to overcome difficulties and expand his territory.
“It’s time!”
Li Yang slowly stood up and stared at the darkening sky outside the window, his eyes as firm as torches.
As a steel warrior of the new era, shouldering the heavy responsibility of the rise of national industry,
He is ready to use his skills to write a new chapter for China Steel!
Not only that, with the support of advanced steelmaking skills, Li Yang also acquired more cutting-edge metallurgical processes and formulas.
The first thing to be affected is the ladle refining technology.
Although traditional converter steelmaking is highly efficient, it still has shortcomings in terms of molten steel quality.
It is easy to produce defects such as pores and inclusions, which affect the performance of steel.
Ladle refining is the process of further purifying and tempering the molten steel using the ladle, a "mobile refining furnace", after the steel is produced from the converter.
Its core equipment is the "purification gun" and "stirring rod" installed above the ladle.
When molten steel flows from the converter into the ladle, workers start the purification gun, penetrate deep into the molten steel, and continuously blow in inert gas, or spray in aluminum particles, silicon Ca and other alloys.
At the same time, the stirring rod rotates at high speed in the ladle, forming a strong centrifugal field.
Under the combined action of gas, alloy and centrifugal force, the impurity oxides in the molten steel are reduced and adsorbed and accumulated in the slag on the surface of the ladle.
The molten steel itself becomes cleaner, more uniform, and has a denser structure.
After refining, the toughness, strength and plasticity of molten steel can be greatly improved.
This laid the foundation for the production of high-quality steel.
Another example is vacuum smelting technology.
This is a refining method that utilizes a vacuum environment.
By vacuuming, the oxygen partial pressure in the steelmaking process can be greatly reduced, thereby inhibiting the oxidation of the molten steel and preventing the formation of inclusions.
At the same time, under vacuum conditions, gas impurities in molten steel can also escape in the form of molecules, greatly improving the purity of the steel.
The most common vacuum smelting equipment is the "RH" vacuum degassing tank.
It consists of two vertical pipes immersed in a steel ladle, with the top of the pipes connected to a vacuum chamber.
When the ladle enters the vacuum chamber, the vacuum pump is started to extract the air in the tube to form a negative pressure.
Under the difference between atmospheric pressure and negative pressure, molten steel will continuously flow from the ladle into the vacuum chamber through the lower pipe, and then flow back through the upper pipe.
This cycle repeats itself, and every portion of molten steel can be fully degassed and purified.
In addition, during the "RH" refining process, aluminum, silicon, manganese and other alloys can be added in time to adjust the composition of the molten steel.
The use of slag-forming agents such as lime and fluorite can more effectively absorb impurities in molten steel.
In this way, with a two-pronged approach, both internal and external improvements, the quality of molten steel will surely be taken to a higher level!
In Li Yang's mind, a series of refined schematic diagrams of "RH" were clearly visible.
The main body of the equipment is sealed and connected to the bottom of the ladle, like an inverted "U"-shaped tube.
The inner wall of the pipeline is lined with refractory material to resist high temperature erosion of molten steel.
The top end is connected to the argon gas pipeline and the vacuum pump, which are used to blow in inert gas and extract vacuum respectively.
In the middle section of the circulation pipeline, a vibration device is installed to enhance the stirring of the molten steel and accelerate degassing.
In addition, during the circulation process, the operator will add aluminum particles, silicon Ca and other alloys in time.
For this purpose, a special feeding device is provided above the "RH" and is sealed and connected to it.
In this way, while the molten steel circulates, alloy powder is also added and dissolved in the molten steel.
Exquisite design, strict layout, interconnected and integrated.
……
Inside the library, the setting sun gradually casts a layer of dreamy gold on the books in the collection.
Li Yang slowly stood up and stroked the piles of yellowed pages carefully.
Here, between these ancient words, the secrets of steelmaking that have spanned centuries lie quietly.
They are the treasures of China's thousand-year-old metallurgical civilization and the wisdom condensed by generations of steel workers' lives.
And now, all of this will open a new chapter in the hands of this young man.
We have a heavy responsibility on our shoulders and much to do!
Li Yang breathed a sigh of relief, a confident smile appearing at the corners of his lips.
On the system panel, the large words "Steelmaking Skills" flashed brightly.
He knew that with this power, he would be invincible on the iron front.
More importantly, with these drawings and formulas, Geng's workshop's steelmaking capacity will surely undergo a revolutionary transformation!
Holding up the piles of manuscripts, Li Yang took one last look around the library.
The sun has set, the lights are on, and a sacred and solemn atmosphere permeates the bookshelves.
It seems to be passing the baton of time to the trendsetters of this new era.
And Li Yang also secretly swore in his heart:
"I will definitely live up to your trust and fulfill my mission!
With the legacy of these predecessors, we will create a new era for the steel industry.
With this skill, I will contribute all my strength to the prosperity of our motherland!"
As night fell, Li Yang's back disappeared at the entrance of the library.
A bright moon rises slowly, outlining the silhouette of a young man striving for progress.
Li Yang got on his bicycle and sped towards the factory.
Tonight is destined to be a sleepless night
The steel workers in Geng's workshop will welcome a great leader.
Under his leadership, this ancient steel fortress is about to burst into new life!
Li Yang's pace became faster and faster, and his eyes became more and more determined.
……
In the hospital, He Yuzhu stared at the ceiling with lifeless eyes, as if he had lost his soul.
He just learned from the doctor that one of his eggs had been cut off!
This cruel fact almost broke him down.
He Yuzhu lay on the hospital bed in a daze, his mind blank.
He is only in his early thirties, in the prime of his life, but now he has become a "lone egg"
If this news gets out, which girl would be willing to marry him?
Thinking of this, He Yuzhu felt hopeless and extremely disappointed.
Tears flowed uncontrollably from his eyes and slowly flowed down his cheeks.
"Zhu Zi, don't think too much. As long as the person is fine and his life is not in danger, that's the most important thing!"
Yi Zhonghai and an old lady standing by kept comforting her.
Yi Zhonghai patted He Yuzhu on the shoulder and said earnestly:
"An egg is worthless. Many rich people have lost their families, but they still live a carefree life. We will take care of you in the future. Are you afraid that you can't make ends meet?"
