Chapter 74

Although he said he wanted to take Brian to try steelmaking, don couldn't figure out what to do. In a word, he took Brian to get some limestone, then went to the charcoal factory to get some charcoal, and then found an empty place on the edge of the forest to start work.

"Big brother, what are you going to do?"

Brian looked at Donne squatting there studying stones. His face was tangled. He clearly asked himself to watch and study, but he couldn't understand it. He still learned a hair!

"Firing limestone."

"Limestone?"

"Here are these stones."

Donne pointed to the limestone next to him: "quicklime is needed for steelmaking. When these limestone are calcined at high temperature, quicklime and a gas will be generated."

"This kind of stone? We have it all over the ground."

The ambris mountains themselves are a super huge mineral vein. Coupled with the dwarf digging around, it is normal to have a lot of limestone.

"Oh, remember, this kind of stone is essential for steelmaking."

When Donne finished, he probably remembered almost. With a hook in his hand, the mage's hand grabbed the limestone and floated up. Then an idea flashed, and a cluster of hot flames suddenly appeared in the air.

"Eh!? brother, are you a magician?"

Brian was very surprised: "I always thought you were a soldier according to your fighting situation!"

"Don't tell anyone."

Donne said casually, but his eyes were fixed on the limestone, and the temperature of the flame kept rising.

"Why?"

Brian scratched his head: "magicians are much more popular than soldiers. If your people know that you are a magician, they probably worship you more and obey you more. If I were you, I would tell them why you should keep it a secret? Do you want to keep a sense of mystery? Do you have enemies? Or --"

"If you talk nonsense again, get out of here!"

Donne's face is tangled. Brian works actively, fights actively and has a good person. It's no problem to be a friend, but why does he talk so much? Especially after drinking wine, it's like a dam with a gate open

Brian said boldly, "how can you forbid me to speak? The goddess gave us --"

Silence.

Donne's lips moved and Brian's voice disappeared in an instant.

Eh? Why is there no sound?

Brian touched his lips and opened his mouth again. He still didn't make a sound. Suddenly he was worried and shouted desperately. Unfortunately, he still didn't make a sound.

Donne was too lazy to talk to him and devoted himself to calcining limestone.

Soon the color of limestone turned white. The mage's hand shook gently, and a layer of dusty calcium oxide, the so-called quicklime, fell down on it.

With the help of magic, in just a few minutes, the limestone crushed by Donne was calcined and completely turned into quicklime.

After putting away the pile of quicklime, Donne looked back at Brian, but almost laughed.

The guy dug up with his hands and his mouth wide open. Did he think there was something wrong with his voice?

Donne lifted the silence and said, "next time you talk nonsense, I'll keep you from talking all day."

"Big brother, I -- eh!? can speak! Damn it -- it's your magic!"

Bryant jumped up as he said, "you've imprisoned my right to speak!"

"Magic works at this time."

Donne said with a straight face, "are you going to watch it?"

"I --"

Brian said dejectedly, "well, you won!"

Brian wanted to have a good fight with Donne, but on second thought, Donne didn't play much melee. Now he knows he's still a mage. How can he fight!

Donne pointed to the pile of quicklime and said, "see, these are quicklime."

Brian leaned over and looked, "I haven't seen it."

"It's normal... Don't get close to it. It'll be a big trouble in your eyes."

"When it meets water, it ripens into lime and releases a lot of heat. It's very dangerous," Downe said

"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~~~~
