As the molten iron surging, silicon and manganese were first oxidized, and then it was the carbon in pig iron.
At a high temperature of nearly 1,500 degrees, carbon and oxygen in the air combine to form carbon monoxide, and the heat released makes the furnace boil, and the flames sprayed out of the furnace almost engulf the blower and the furnace stand. This is why the brackets also need to be covered with heat-resistant coating.
A large amount of carbon monoxide escaped, contacted the abundant air outside at the furnace mouth, and then burned violently, as if the furnace was lit.
The thunderous sound of gas expansion overshadowed the sound of the steam engine for a moment. Everyone couldn't help but retreat one after another in front of this scene like a volcano eruption. Only Roland was standing with his hands on his back, facing the hot wind, completely immersed in the roar of steel flames.
Unfortunately, current technology can only be used to make steel by injecting air. If it can be replaced with pure oxygen in the future, the fireworks will be even brighter.
The final reaction is phosphorus and sulfur. When the oxides and limestone of these two form slag, the flame begins to retreat, and the molten iron has basically become steel.
The lighter slag floats on the liquid steel. As long as the converter is tilted, the steel can be poured out from the steel outlet like pouring tea.
If we follow the rules of modern steel mills, we must also block the slag balls, block the slag darts, and use infrared detection to prevent the upper layer of scum from flowing into the transport ladle.
Without Winter City's current technology cannot do this, so Roland's solution is also very simple, that is, don't pour it too clean. When there is still a small amount of molten steel in the furnace, lift the furnace directly, and then pour them out with the slag. If you waste a little, you can waste it. If you collect too much, you can return it to the furnace and refine it. Anyway, he doesn't have to pursue any production benefits.
In order to ensure the quality of steel, the finishing work is to remove excess oxygen from the molten steel.
The bauxite transported from Changge Fortress can just act as a deoxidizer. A barrel of pure aluminum separated by Lucia is poured into the molten steel, and the alumina slag produced floats to the surface together with the unreacted aluminum. At this point, the entire steelmaking process is completed.
When bright liquid steel flowed into the mold and turned into dark red ingots, the city hall officials were shocked to speak.
The main means of steel making in this era are still at the level of forging steel. A piece of steel full-body armor can be passed down from generation to generation. No one has seen steel be produced like running water. Even if the Steel Star can produce a large amount of steel, most people regard it as an accessory to the witch's ability. Without Anna and Lucia, this kind of steel would definitely not be produced.
But this time it was different. Only when they saw that converter steelmaking could be done without relying on the power of witches, but they could do it with the hands of ordinary people alone, could they vaguely understand what this means?
There is only one Steel Star, but there are countless converters and workers.
Steel is no longer a rare material, and in the future, this strong metal will be produced from the foot of the North Slope Mountain to replace those soft and brittle wooden and bronze utensils.
Roland was very satisfied with the fear expressions of the city hall officials. If he could not be shaken by the magnificent beauty displayed during the steelmaking process, he would probably not be a qualified leader.
Workers may only see the steel ingots in front of them, and they should be able to see the future represented by the steel ingots.
At this point, Wudongcheng's coal-iron review industry has begun to take shape, from mining to iron smelting, and then from iron smelting to steelmaking, and finally casting steel into various objects. This process can be achieved by ordinary people.
Coupled with the rapid growth of population and popularization of education, Roland can already hear the sound of the wheel of steel rolling over the earth.
It is true that Lucia needs to conduct further inspection on the quality of the newly released steel, and slowly adjust the blowing time and slag removal formula based on the test results, but all of this has finally begun.
……
Roland, who completed a great cause, did not stop at all. With the help of the memory replay of the dream world, he still had a lot of work to do.
Now that the primary textbooks have been completed and re-edited, he has turned his attention to a higher level of mechanical professional textbooks. Now that winter city has the foundation for mass production of steel, high-performance processing equipment is undoubtedly what he urgently needs in the next step.
The initial batch of simple machine tools are no longer suitable for processing high-end products, and they seem a little overwhelmed when facing parts such as fortress cannons, heavy machine guns, grenade fuzes.
So where to find detailed drawings?
The school library may be a good choice. Roland went there a lot when he was studying, and he never encountered the legendary encounter. He read a lot of miscellaneous books, including many of which involve the principles of mechanical design.
After dinner, he lay on the bed early.
Since wandering in another world is not considered sleeping, the first daytime will be very hard based on normal hours. In addition, there is no air conditioning in the apartment building, and taking a nap in the hot noon sun has become a delusion.
He could only fall asleep early and use this part of the energy saved in his dreams.
Entering the dream, it is still the sunny morning in the midsummer.
There were more than a dozen phones on the bedside phone. When I clicked on it, I saw that they were all called by the second dealer, and the same was true in the text box.
Brother, do you still have armor there?I have a friend who happens to want to stop filming, so if you have, contact me immediately.
The price can be opened higher this time, how about seven hundred?
The swords and swords also increased by 200, which is great.But you don’t need to open your head, it looks scary.
If you are not satisfied with the price, we can talk about Ah again.
Brother, can you reply?
Roland turned directly to the last text message, which was sent by the bank, indicating that the balance in the card had increased to 3,600 yuan, of which the newly recorded 1,500 yuan was the living expenses received by Jieluo's family.
This money has been enough for him to spend a long time.
He tapped his fingers gently, deleted all text messages, put on short-sleeved shorts and walked into the living room.
Jieluo hasn't gotten up yet at this time.
Roland was too lazy to wait for the little girl to make breakfast, so he walked downstairs and found a noodle shop in the alley and sat down.
Boss, a bowl of shredded pork noodles, large portions.
OK!
Since you have money, you naturally have to enjoy it, right?You know, this is a delicacy that even the king cannot enjoy. After all, Gray Castle has no rice.
The scalded vermicelli was quickly brought up, and Roland was eating breakfast while looking at the apartment building opposite.
So far, the longest distance he has ever taken action is the old bookstore and small Internet cafe two streets away. Because he is busy raising money and memorizing information, this is the first time he has left his spare time to observe the residents in the Soul Tower from another perspective.
