Chapter 74 (2/2)

”Oh? Isn't it good for Yin people in battle?”

Brian just said casually, but Donne brightened his eyes and found another use of quicklime.

In other words, when watching the story of the deer tripod, trinket killed many enemies with quicklime. It can be seen how powerful quicklime is. People here in prandal have never seen quicklime. They certainly don't know how to deal with quicklime. If this big killer is suddenly sacrificed in battle

Dunn wrote this down silently and said, ”quicklime and charcoal are ready. Now you can make steel.”

”How?”

”The ore was to be smelted first, but in order to save trouble, I got some raw iron ingots from Edgar.”

Donne said and took out some raw iron ingots. The magic flame burst into a high temperature of more than 2000 degrees. In a short time, he melted those raw iron ingots into molten liquid.

”After the pig iron melts, blow these charcoal and quicklime into the melt...”

Coke is widely used in steelmaking on earth. Coke is produced by dry distillation of coal mines isolated from air at high temperature and pressure. At present, don hasn't heard of a coal mine in prandal. Naturally, he won't consider coke. However, charcoal is actually better for steelmaking, although the consumption of charcoal is large, But... Isn't the endless ladhian forest and Emerald Forest next to Ellington the best source of charcoal?

As long as you use and plant, don't annoy the elves

Brian scratched his head: ”why blow in carbon and quicklime?”

”Because iron is not pure, iron ore inside... How can I explain if I wipe it?”

Donne is tangled. Do you want to popularize basic chemistry with Brian?

”Iron ore is actually a composite product called iron oxide. The process of melting iron ore is actually the process of removing impurities inside. The higher the fusion temperature, the more sufficient the reaction...”

Donne wanted to talk about redox reaction. You can see Brian's dull face, but he decided to forget it.

Anyway, his chemistry is only half level

When blowing charcoal, in order to increase the degree of reduction, Donne also used the wind magic to blow a lot of air into the melt - pure oxygen should have been blown, but Donne can't make and store gas raw materials at all

It's easy to make pure oxygen. Get an electrolyzer to electrolyze pure water. The gas at the cathode is hydrogen and the gas at the anode is oxygen. Even if you don't know which side of the electric magic is the cathode and which side is the anode, you can just try it at that time

But the problem is storage.

Donne can't make a high-pressure storage tank to store the produced gas

So we can only use the simplest way to blow in a lot of air.

”As for why quicklime is blown in so that the impurities in the melt can condense together to form slag. See? Those tumbling things above? Those are the slag from quicklime.”

Donne motioned Brian to see the slag clearly. With the stirring of the mage's hand, many blocks floated on the molten iron. Brian looked carefully and was stunned: ”these raw iron ingots were fired by Edgar and I, and there are so many impurities in them?”

”Of course, many things can't be seen by the eyes, but it doesn't mean they don't exist.”

Don shrugged his shoulders and stared at the flames on the molten iron. When the flames weakened and became weak, don filtered out all the slag - this can be easily achieved by using spells.

In fact, the process of steelmaking is much more complex than these, but Donne himself only remembers so many, and he can't remember other complex processes.

After stirring the molten iron to fully react the toner and iron, Donne plans to set the shape.

As for other processes... Ha ha.

After the magic flame stopped, the molten iron was bound by Donne's magic and turned into square shapes. After cooling, it was placed neatly.

Brian leaned up and touched, ”big brother, is this steel?”

”Well, probably -”

Because his memory is too vague and unprofessional, Donne is not sure whether he succeeded in this attempt, but of course he can't lose face in front of Brian. He smiled proudly and waved his hand, ”-- of course! It's carbon ferroalloy, but... You don't care about the name. This is steel. Well, yes, it must be steel!”

”But it looks no different from raw iron ingots.”

”There's a big difference... Go back and try making some weapons with these steel.”

Donne manually refined dozens of kilograms of ”steel” this time, which is enough for Brian's experiment.

”No problem!”

Brian is very interested in experimenting with new materials. He really wants to know how superior the ”carbon iron alloy” Dunn calls is.

The two began to return. Donne was meditating all the way. If this can refine some steel that can be put into practical use, then the steel plant can be considered to start construction. Before that, the problem that needs to be solved is how ordinary workers should realize several important process means halfway.

Carbon blowing and lime can use constant magic auxiliary tools, and slag removal can also be realized by using high-temperature magic metal manufacturing tools. Mixing can be realized by adding a magic array at the bottom of the steelmaking furnace and controlling the output of magic through an external simplified switch

After going through the process in his mind, Donne breathed a long sigh of relief. With his poor knowledge reserve, he could only do so. If even what he refined was that kind of scrap steel, he could only consider other means - prandal is a magical world, and it is normal to make some strange special alloys, Maybe there are better alloy materials than steel?

After returning to Ellington, Brian immediately began to test the properties of steel=== PS: I almost forgot to update... After watching the vote~~~~
