Release that Witch

658. Chapter 658 Steel and Dreams

    Under the tumbling of molten iron, silicon and manganese were first oxidized, and then the carbon in the pig iron was turned.

    In the high temperature of nearly 1,500 degrees, carbon combines with the oxygen in the air to form carbon monoxide. The heat released “boiling” the furnace, and the flame from the mouth almost absorbs the air pipe and the hob – This is why the bracket also covers the heat-resistant coating.

    A large amount of carbon monoxide escapes outward, and it is in contact with the outside air at the mouth of the furnace, followed by intense combustion, which is like igniting the furnace. The squeaking sound of the gas swelled over the steam engine for a time, and everyone could not help but retire before the scene like a volcanic eruption. Only Roland was carrying a both hands, standing against the hot wind, completely immersed in the flames of steel. Roaring.

    Regrettably, the current technology can only be filled with air to make steel. If it can be replaced with pure oxygen in the future, the fireworks will be even brighter.

    Finally, the reaction is phosphorus and sulfur. When the oxides of the two and the limestone form slag, the flame begins to retreat. At this time, the molten iron has basically become steel. The lighter slag floats on the molten steel, and as long as the converter is tilted, the molten steel can be poured out of the taphole like pouring tea.

    According to the rules of modern steel mills, at this time, the slag ball, the slag dart, and the infrared detection method are used to prevent the upper scum from flowing into the steel ladle. The current technology of Neverwinter City is still not able to do this, so Roland’s solution is also very simple, that is, don’t fall too clean, if there is still a small amount of molten steel left in the furnace, the furnace will be directly lifted, and then they will be poured out together with the slag. If you waste a little, you will waste a little. If you collect more, you can re-refin it. Anyway, he does not have to pursue any production benefits.

    In order to ensure the quality of the steel, the finishing work is to remove excess oxygen from the molten steel.

    The alumina that is continuously transported from Longsong Stronghold acts as a deoxidizer. A bucket of pure aluminum separated from Lucia is poured into molten steel, and the resulting alumina slag is floated together with unreacted liquid aluminum to the surface. At this point, the entire steelmaking process is completed.

    When the bright molten steel flowed into the mold and turned into a piece of dark red steel ingot, the City Hall officials had been shocked to speak.

    The main means of steelmaking in this era is still at the level of 100-forged steel. A steel body can be passed down from generation to generation. No one has ever seen steel produced like flowing water – even “Iron Star” It has been able to produce steel in large quantities, but most people regard it as an accessory to the ability of the witch. Without Anna and Lucia, the steel can not be produced.

    But this time it is different. If you don’t need to rely on the power of the witch, you can only know what it means by the ordinary people’s both hands.

    There is only one “Iron Star”, but there are countless converters and workers.

    Steel is no longer a rare material, and in the future this sturdy metal will be produced from the foot of the Northern Slope Mountain, replacing those soft and fragile wooden and bronze appliances.

    Roland is very pleased with the fear of the City Hall officials – if it can’t be shaken by the majestic beauty of the steelmaking process, it is not expected to be a qualified leader. Workers may only see the ingots in front of them, and they should be able to see the future represented by the ingots.

    At this point, Neverwinter City’s coal-iron composite industry has begun to take shape – from mining to smelting iron, then from smelting iron to steelmaking, and finally casting steel into various objects, a process that can be done by ordinary people. Coupled with the rapid growth of population and education popularization, Roland has been able to hear the sound of the steel wheel running over the earth.

    It is true that the quality of the newly-released steel is still in need of further inspection by Lucia. The blowing time and the slag-removing formula are slowly adjusted according to the test results, but all of this has finally started.

……

    Roland, who has completed a great career, has not stopped. With the memory replay of Dreamworld, he still has a lot of work to do.

    Now that the primary textbook has been completed and rewritten, he has turned his attention to a higher level of mechanical professional textbooks – Neverwinter City now has the basis for mass production of steel, then high-performance processing equipment is undoubtedly his next step s things. The batches of simple machine tools that were originally manufactured have become less and less suitable for processing high-end products, and they are a bit overwhelming when faced with components such as stronghold guns, heavy machine guns, and grenade fuzes.

    So where is the detailed drawing?

    The school library may be a good choice. Roland didn’t go there when he was studying. The legendary cricket didn’t meet it once. It was a lot of books, and many of them involved the mechanical design principles.

    After eating dinner, he lay down on the bed early.

    Since wandering in another world is not a sleep, so the first day during the normal time will be very hard, plus there is no air conditioning in the apartment building, and the hot midday sun has become a reverie. He can only fall asleep early and use this part of his energy to save his dreams.

    Entering the dream is still sunny in the early summer morning.

    There were more than a dozen missed calls on the bedside phone. They were all called by two traffickers, and the same was true in the SMS box.

    “eldest brother, do you still have armor? I have a friend who just wants to take some pictures, and if you have any, contact me immediately. “

    “This price can be opened a little higher, how about seven hundred?”

    “The swords are also up two hundred, which is enough.” But don’t have to start the front, look at the strange scary. “

    “We can talk about it if we are not satisfied with the price.”

    “eldest brother, are you going back?”

    Roland turned directly to the last text message, which was sent by the bank. The balance of the card has risen to 3,600, and the newly-accounted one thousand is the living expenses of the Zero family.

    This money is enough for him to use for a long time.

    He tapped his finger, deleted all the text messages, put on short-sleeved shorts and walked into the living room.

    Zero has not yet got up at this point in time.

    Roland was too lazy to wait for the little girl to make breakfast, went straight downstairs, and found the powder shop in the alley to sit down.

    “Boss, a bowl of pork powder, big.”

    “Well!”

    Since you have money, naturally you have to enjoy it, right? Be aware that this is something that even the Kingdom Capital can’t enjoy – after all, Greycastle has no rice.

    The hot noodles quickly came up, and Roland was eating breakfast while looking at the apartment building opposite.

    So far, the farthest distance he has ever worked, that is, the second-hand bookstore and the small Internet cafes outside the two streets. Because he is busy collecting money and memory information, this is his first leisure time, from another angle, the Building of Residents in Soul.
