Release that Witch Chapter 658: Steel and Dream

Under the surging molten iron, silicon and manganese were first oxidized, and then it was the carbon in pig iron.

At a temperature of more than 1,500 degrees, carbon and oxygen in the air join to form carbon monoxide. The heat released causes the furnace to “boiling”, and the flame emitted from the furnace mouth almost absorb blowpipe and furnace frame. This is The reason why the stent is also covered with a heat-resistant coating.

A large amount of carbon monoxide escaped, contacted with ample air outside at the mouth of the furnace, and then fiercely burned, just like lighting the furnace. The scream of gas expansion overwhelmed the sound of steam engine for a while. Everyone couldn't help but recede before this volcanic eruption. Only Roland was carrying both hands, standing against the hot wind, completely immersed in the roar of steel flames. in.

Unfortunately, the current technology can only infuse air to make steel. If it can be replaced with pure oxygen in the future, this firework will be brighter and brighter.

Phosphorus and sulfur are the last to participate in the reaction. When the oxides of these two and limestone form slag, the flame begins to retreat, and at this time the molten iron has basically become steel. The lighter **** floats on the molten steel. As long as the converter is tilted, the molten steel can be poured out of the tap hole like tea.

If you follow the rules of modern steel plants, at this time, you must lower the **** ball, **** dart, and use infrared detection to prevent the upper scum from flowing into the ladle. Neverwinter City's current technology can't achieve this, so the solution of Roland is also very simple, just don't pour too clean, lift the furnace directly when there is a small amount of molten steel in the furnace, and then pour them out with the slag. If you waste a little, waste a little. If you collect more, you can return to the furnace for refining. Anyway, he doesn't need to pursue any production efficiency.

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

The bauxite continuously transported from Longsong Stronghold can just act as a deoxidizer. A bucket of pure aluminum separated from Lucia is poured into molten steel. The alumina **** generated along with unreacted aluminum floats to the surface. So far the entire steelmaking process is complete.

When the bright molten steel flows into the mold and turns into pieces of dark red steel ingots, the officials of City Hall have been shocked to speech.

The main means of steelmaking in this era is still at the level of one hundred forged steel. A steel body armor can be passed down from generation to generation as a heirloom. No one has ever seen that steel can be produced like running water even if "Iron Star "It is already able to produce a large amount of steel, but most people regard it as an accessory to the witch capability. Without Anna and Lucia, this steel can't be produced.

But this time is different. When they saw that converter steelmaking does not need to rely on the power of witch, ordinary people's both hands can do it, and they just realized what it means.

There is only one "Iron Star", but there can be countless converters and workers.

Steel is no longer a rare material. In the future, this strong metal will be produced at the foot of Northern Slope Mountain, replacing those soft and brittle wooden and bronze appliances.

Roland is very satisfied with the horrified expressions revealed by City Hall officials. If it cannot be shaken by the majestic beauty displayed during the steelmaking process, it is estimated that it will not be a qualified leader. Workers may only see the ingot in front of them, and they should be able to see the future behind the ingot.

At this point, the coal and iron review industry of Neverwinter City has begun to take shape from mining to iron smelting, from iron smelting to steel making, and finally casting steel into various objects. This process can be completely realized by ordinary people. Coupled with the fast-growing population and the popularization of education, Roland can already hear the sound of the wheel of steel running over the earth.

It is true that the quality of the newly-released steel products requires Lucia for further inspection, and according to the test results, slowly adjust the blowing time and **** removal formula, but this has finally started.

...

Roland, which completed a great undertaking, didn't stop at all. With the memory replay of the dream world, he still has a lot of work to do.

Now that the primary textbooks have been completed and re-edited, he has turned his attention to higher-level mechanical professional textbooks. Neverwinter City now has the basis for mass production of steel, so high-performance processing equipment is undoubtedly his next urgent need. s things. The batches of simple machine tools that were originally manufactured are increasingly unsuitable for processing high-end products, and appear to be inadequate when facing parts such as the stronghold cannon, heavy machine gun, and grenade fuze.

Where can I find detailed drawings?

The school library may be a good choice. Roland did not go there when reading, and the legendary encounter did not come across it once. I read a lot of miscellaneous books, and many of them involved mechanical design principles. Content.

After dinner, he lay in bed early.

Wandering in another world does not count as sleeping, so the first day of the day will be very hard if you work and rest at normal time. In addition, there is no air conditioning in the apartment building, and it will become a delusion to face the hot midday sun. . He could only fall asleep early, using this part of the energy saved in his dreams.

Into the dream, it is still the sunny summer morning.

There are more than ten missed calls on the bedside mobile phone. When you open them, they are all called by second-hand traffickers, and the same is true in the message box.

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

"The price can be higher this time. How about seven hundred?"

"The swords have also gone up by two hundred, which is interesting. But don't start, look at the weird."

"We can talk about the price unsatisfactory."

"eldest brother, would you like to reply?"

Roland turned directly to the last text message, which was sent by the bank. It showed that the balance in the card had risen to 3,600 yuan, of which the new account of 1,500 was the living expenses from the Zero family.

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

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

Zero has not yet got up at this time.

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

"Boss, a bowl of shredded pork, large portions."

"Oh!"

Now that you have money, you have to enjoy it, right? You know, this is the food that Lian Guo Kingdom Capital cannot enjoy. After all, Greycastle has no rice.

The hot noodles were brought up quickly. Roland was eating breakfast while watching the apartment building opposite.

So far, the longest distance he has ever acted, which is second-hand bookstore and small Internet cafes two streets away. Because he is busy collecting money and memory data, this is the first time he has spared time and looked at Building of Soul from another angle Residents.
