Fu Song believes that there is no need to give a detailed description of China's four major steel mills, or the four major steel giants.
Because as long as you know that it is because of the existence of the four major steel mills that China has the confidence to promote its heavy industry to the world.
Take a deep breath, look at the "students" behind Wang Weidong, and then look at the high-spirited Wang Weidong.
Fu Song realized that even though he had prepared himself mentally, he still underestimated the security guard.
The other party's status in the steel industry is definitely not weaker than that of the Western Melon King Hao Yuezhu.
He greeted everyone with a smile, and Fu Song stood quietly by the side, acting as a nobody.
Wang Weidong waved his hand and said, "Let's get started!"
Immediately, workers began adding raw materials to the blast furnace.
The raw materials for making steel are very simple: iron ore and charcoal.
The refining principle is simpler, that is, in a high temperature environment, the reducing property of charcoal is used to reduce the high-valent iron in iron ore into elemental iron.
The elemental iron is then fused with excess charcoal to form an iron-charcoal alloy, namely steel.
The history of steelmaking is also very long, dating back to the Spring and Autumn Period and the Warring States Period.
However, making steel is easy, but making a furnace of good steel is extremely difficult.
The simplest one is the carbon content in steel. Steels with different carbon contents exhibit completely different properties.
The higher the carbon content, the more ductile the steel will be, but the harder it will be.
The lower the carbon content, the harder the steel will be, but the ductility will decrease and it will be more likely to break.
The idiom "too rigid to break easily" refers to this situation.
Of course, in order to obtain steel with excellent performance, in addition to the carbon content, other metals such as nickel and chromium must be added.
Pen tip steel is a kind of steel with extremely complex composition and forging process. The hardness of qualified pen tip steel is second only to diamond.
Based on this data alone, one can roughly guess the difficulty of smelting, not to mention indicators such as wear resistance, ductility, and plasticity.
The iron ore slowly melted into juice in the blast furnace. During this process, Wang Weidong kept directing people to add medicines into it, and patiently explained the reasons for doing so.
Even though Fu Song didn't know anything about steelmaking, he still listened to what he heard.
The molten steel in the blast furnace became redder and redder, and Wang Weidong's expression was no longer as calm as before.
He stared closely at the color changes in the furnace and suddenly said, "Add condensate!"
A worker pressed the switch and a large amount of white smoke instantly came out of the blast furnace.
When the white smoke dissipates, the red molten steel in the furnace directly turns into a dark silver solid. This is the prototype of steel, crude steel.
Fu Song was comparing what he saw with theoretical knowledge when he suddenly heard a voice exclaim, "Five tons of molten steel completely solidified in seven seconds. How is that possible?"
After taking a look at the person who was speaking, Fu Song remembered that his name was Su Yumin, a first-class steel engineer at Baosteel.
You can't blame him for being surprised; there are two core elements to steelmaking.
The first is rolling, and the second is cooling.
Steel rolling is a simple process that involves repeatedly pressing the steel to remove impurities and produce high-performance steel.
For example, the blacksmithing commonly seen in TV dramas is the most commonly used steel rolling technology in ancient times.
The cooling principle is similar to that of steel rolling. The most common method is water cooling, that is, after forging, the blacksmith will directly pour a bucket of water on the red-hot iron block.
Of course, modern steelmaking technology will not use such a method that is extremely difficult to control in terms of precision. In Baosteel's laboratory, Su Yumin can find at least 200 cooling methods.
Fourteen of them were invented by him.
However, among these 200 cooling methods, not one can completely solidify five tons of molten steel within 7 seconds.
Wang Weidong looked at Su Yumin and laughed: "Why not?
Forget 7 seconds, I have a way to achieve the same effect in 5 seconds.
If you don't agree, we can make a bet.
How about a 12-ton vacuum induction melting furnace? I remember that's what Baosteel is best at."
Su Yumin waved his hands quickly after hearing this: "I wouldn't dare bet with you, old man. Not to mention 5 seconds, I'd believe you even if you said 3 seconds."
Just kidding, there was an engineer at Anshan Iron and Steel Group who refused to accept the situation and insisted on competing with Wang Weidong.
As a result, I lost all my pants.
With such a previous experience as a lesson, Su Yumin would not be stupid enough to confront the other party head-on.
But while he admitted his mistake, he couldn't help but wonder how the other party did it.
Because for steel, the shorter the cooling time, the better the performance of the steel produced.
So although the steel in the blast furnace is crude steel, its toughness is probably no worse than that of fine steel.
Wang Weidong felt a little disappointed when he saw that he didn't catch any fish. He then ordered his men to take out the steel and put it into a refining furnace for secondary smelting.
Then comes rolling, cooling, adding materials...
Since it was an experiment, Wang Weidong divided the five tons of steel into thirty groups and forged them in different ways.
Because of the heavy workload, the technicians who were learning from him no longer just took notes.
They directed the workers according to Wang Weidong's experimental plan, while they themselves kept measuring various data and making comparative analyses.
Fu Song was originally very curious about steelmaking, but soon lost interest.
In addition, the steel is subjected to high temperatures throughout the forging process, and it will explode if you are not careful.
In just half a day, the blast furnace used for preliminary smelting of iron ore exploded three times.
Although no one was injured, Fu Song was still frightened.
As a business genius, I am good at making money, not experimental research.
So I decided to go back to the office to have a cup of tea and help Morning Star Pen Refill Factory design its future development direction!
Fu Song did it as soon as he thought of it. He turned around and slipped away while no one was paying attention.
