Chapter 1604 Wang Yingxuan Steelmaking Method

Previous page        Return to Catalog        Next page

    "Add ingredients!" Wang Yingxuan said loudly again.

    The workers added ferromanganese alloy into the red molten steel.  One is to remove the pores produced in the steel during the reaction, and the other is because the reaction was too violent, all the carbon was removed, and what was produced was actually wrought iron, so a little carbon had to be added to the steel.

    ¡°It¡¯s time to start the stove!¡± Finally, Wang Yingxuan suppressed his excitement and shouted tremblingly.

    The workers worked together to turn the huge gears on both sides and cooperated with the new crane to slowly tilt the converter.  When the converter is tilted to a certain angle, a blazing torrent will flow out from the furnace mouth, which is so brilliant that it is impossible to look at it.

    The molten steel flows vertically into the cold iron ingot mold. The mold expands when heated and the molten steel solidifies and contracts, so there is no need to worry about sticking together.  After it cools down, the mold is turned back and tapped, and the steel materials of various shapes fall off from the mold.

    Zhu Shimao and others' hearts finally returned to their stomachs.  Good guy, this is so exciting

    ??~~

    Everyone went outside to drink cold drinks, take a shower, and change their clothes.  When he came in again, the researcher handed three finger-thick steel bars to Mr. Zhao, Director Wang and Jiangnan Iron and Steel Chairman Wang Yu.

    Wang Yu has been dealing with steel for half his life. His family was originally located in Wangji Steel Factory in Wuhu, which was the most advanced steelmaking factory in the entire Ming Dynasty and even the world at that time.  Although he has seen too much of the power of Institute 01 over the years, he still can't believe that steel can be made by simply blowing.  It's almost enough to brag

    In Wang Yu¡¯s heart, steel is sacred and is tempered thousands of times.  Even the most advanced technology now requires the entire process of melting iron ore to obtain pig iron, refining pig iron to obtain wrought iron, and then carburizing to obtain steel.

    The first two steps are easy to say, just start with the blast furnace, the output is large and it is not too troublesome, but steelmaking is very arduous.

    It takes six or seven days for the iron to be heated to become high-carbon carburized steel, but at this time the iron only contains carbon on the surface, but the inside is the same as before.  If it is used to produce high-quality steel for sword blades, craftsmen are required to continuously beat, fold and carburize it in the forge until the carburized steel layer reaches the required thickness.

    All processes require large amounts of fuel and skilled labor and are extremely costly.  That¡¯s why ¡®steel¡¯ is so sacred and noble in the minds of blacksmiths.  How can it come out of the blast furnace directly like iron?

    Is it true? Is it true?  Does steel still have dignity?  Is that still valuable?

    He was thinking wildly, while Wang Yingxuan was trying hard to break the steel bar with both hands, but even with all his strength, there was no sign of bending.

    Lao Wang held the steel bar with both hands and smashed it against an iron ingot on the side. Sparks flew, but the steel bar did not snap or deform like before.

    This shows that the sulfur content and carbon content should be qualified.

    Wang Yingxuan is not happy at all, because the strength of steel with high phosphorus content will be significantly improved.  But phosphorus is more harmful. It reduces the plasticity and toughness of steel and makes it cold brittle.  It is because the phosphorus in the steel cannot be removed that Institute 01 has been stuck in place for so many years.

    Although in theory, because iron ore does not contain phosphorus, steel should also not contain phosphorus.  But Lao Wang has had many happy events in recent years, so he has become extremely cautious.

    He then asked someone to take a piece of freshly made steel and stuff two bricks into the left and right ends of it.  Then hit it hard with a big hammer.

    With the loud banging sound, the steel was slightly bent every time by the hammer, and then rebounded back to its original shape without any signs of breaking or shattering.

    Beating and beating, Wang Yingxuan couldn't help but burst into tears.

    Because this shows that the phosphorus content in the steel is also qualified, otherwise it would not have such toughness

    Witnessing this scene, Wang Yu opened his mouth in surprise.  But he was still unconvinced and called another guard, who pulled out a steel knife and cut the steel bar in his hand.

    With one slash of the knife, fire flew out, and the steel knife left a shallow white mark on the steel bar.  Wang Yu simply took the knife and chopped at the same spot repeatedly.

    Until the steel knife was sharpened, the white mark on the steel bar only became larger and darker, and it was nothing serious.

    ?Obviously the hardness is also qualified.

    Strength, hardness, toughness and elasticity are all qualified isn't it steel?

    "Is it really steel?" Wang Yu was dumbfounded.

    "Based on these characteristics, it should be high-carbon steel with a carbon content greater than 8% per thousand." Wang Yingxuan also suppressed his excitement and said: "But it still needs to be tested to get the accurate carbon content!  "

    "Then why are you still standing there? Go quickly!" Zhao Hao patted him on the shoulder.

    "Okay, let's go now!" Wang Yingxuan immediately took the sample and ran to the next door. In order to facilitate the testing,What a beautiful thought Mr. Zhao wiped the drool from his mouth and smiled bitterly. Just what he imagined in his daydream, I am afraid that the production capacity will not be reached in ten or twenty years.

    ¡°Alas, we still have to be down-to-earth and work hard!

    He glanced at Wang Yu and said with a smile: "How about it, are you interested in being the person in charge of this coal and steel complex?"

    "I'm sure I'll be interested!" Wang Yu agreed: "Even if the young master doesn't tell me, I still have to shamelessly volunteer!"

    As he spoke, he said with a smile: "After seeing the converter steelmaking method here, I can no longer understand the original methods. I can't go back, I really can't go back"

    "It's okay if we can't go back. We just have to stride forward and go as far as possible!" Zhao Haohao said angrily: "Let our descendants live in a world of steel!"

    "Young Master is so romantic" Lao Wang and Lao Wang were so shocked by what Zhao Hao said that they shed tears.

    Zhu Shimao and others disagreed. What's so good about the world of steel?  It is gray and rusty, how can it have the beauty of mountains, rivers and countryside?

    However, the landscape and countryside are vulnerable to a world of steel

    ps. It¡¯s another day when no one helps to look after the childrentwo mythical beasts.  It¡¯s gone tonight, but it will be fine tomorrow. The little one is going to kindergarten.  Try to make up for what you owe today.  (Remember the website address: www.hlnovel.com
