Although he said that he was going to take Brian to try steelmaking, but in fact he didn't know what to do, so he took Brian to get some limestone, then went to the charcoal factory to get a batch of charcoal, and then found a place at the edge of the forest where no one was supposed to start work.

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

Brian watched Don squatting there studying the stones, with a tangled face, obviously asked himself to come to watch and learn, but he couldn't read it, and he still learned it!

"Fired limestone."

"Limestone?"

"Well, these are the stones."

Donn pointed to a few limestones next to him: "Quicklime is needed to make steel, and these limestones are calcined at high temperatures to produce quicklime and a gas. ”

"This kind of stone? We're all over the ground. ”

The Ambris Mountains themselves are a huge vein, and with the dwarves digging around, it's normal for a lot of limestone to be poured.

"Oh, then you remember, this kind of stone is indispensable for steelmaking."

After Tang En finished speaking, he probably remembered it almost, he hooked it casually, and the mage's hand grabbed the limestone and floated up, and then a thought flashed, and a cluster of blazing flames suddenly appeared in the air.

"Huh!? Big brother, are you a magician? ”

Brian was very surprised: "Looking at your battle before, I always thought you were a warrior!" ”

"Don't tell anyone."

Don 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 warriors, if you let your people know that you are a magician, they will probably worship you more and be more obedient, if it were me, I would definitely tell them, but why should you keep it a secret?" Do you want to keep it mysterious? Or do you have enemies? Or do you mean—"

"If you talk nonsense, fuck me off!"

Don En looked tangled, this Brian is active in work, active in fighting, and a good person, it's no problem to be a friend, but why is there so much to talk about? Especially after drinking, it is like a dam that has opened the floodgates......

Brian said confidently, "How can you forbid me to speak? Speech is given to us by the goddess—"

Silence.

Don's lips moved slightly, and Brian's voice disappeared in an instant.

Hey? Why is there no sound?

Brian touched his lips and opened his mouth again, but he still didn't make a sound, and suddenly he was in a hurry, and roared desperately at the top of his throat, but unfortunately he still didn't make a sound at all.

Don didn't bother to talk to him, and concentrated on calcining the limestone.

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

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

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

This guy actually dug in with his hands with his mouth wide open, did he think there was something wrong with his throat?

Don En lifted the silence technique and said, "Next time you talk nonsense, I'll make you unable to speak for a day." ”

"Big brother, I-huh!? I can talk! Damn it - it's your spell! ”

Brian suddenly jumped up: "You actually imprisoned my power to speak!" ”

"That's when spells come into play."

Tang En said with a straight face: "Are you still going to continue watching?" ”

"I—"

Brian hung his head and said, "Well, you win!" ”

Brian originally wanted to have a good fight with Don En, but after thinking about it carefully, Don couldn't fight much in close combat, and now he knows that he is still a mage, how can he fight!

Tang En pointed to the pile of quicklime and said, "See, these are quicklimes." ”

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

"It's normal...... Don't get into it, it's a big problem if you get it in your eyes. ”

"This thing becomes mature lime when it comes into contact with water, and it also emits a lot of heat, which is dangerous," Donn said. ”

"Oh? Wouldn't it be nice to be a yin person in battle? ”

Brian just said it casually, but Donne's eyes lit up and he discovered another use for quicklime.

It is said that when he first watched Lu Ding Ji, Wei Xiaobao relied on the magic weapon of quicklime to kill a lot of enemies, which shows how powerful quicklime is......

Don silently jotted it down, then said, "The quicklime and charcoal are ready, and now it's time to make steel." ”

"How?"

"Originally, I was going to smelt the ore first, but to save trouble, I got some pig iron ingots from Edgar."

As he spoke, Don took out some pig iron ingots, and the magic flames instantly erupted into a high temperature of more than two thousand degrees, and in a short time, those pig iron ingots melted into melted liquid.

"After the pig iron melts, the charcoal and quicklime are blown into the melt......"

Coke is commonly used in steelmaking on the earth, coke is distilled by high temperature and high pressure in the coal mine isolated from the air, and at present, Don has not heard of a coal mine in Plandal, so he naturally will not consider coke, but then again, charcoal for steelmaking is actually better, although the consumption of charcoal is large, but ...... Aren't the endless Ladian and Emerald Forests next to Ellington the best sources of charcoal?

Just use whatever you want and don't mess with the elves......

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

"Because iron is not pure, iron ore is ...... How do I explain my rub? ”

Donn is entangled, 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 temperature of fusion, the more fully the reaction ......"

Don originally wanted to talk about the redox reaction, but he decided to forget it after seeing Brian's sluggish face.

Anyway, his chemistry is only half-baked......

When blowing into the charcoal, in order to increase the degree of reduction, Donn also used a wind spell to blow a large amount of air into the melt - it should have blown in pure oxygen, but Donn has no way to make the raw materials for storing gas now......

It's easy to make pure oxygen, get an electrolyzer to electrolyze pure water, the gas of the cathode is hydrogen, and the gas of the anode is oxygen, even if you don't know which side is the cathode and which side is the anode using the electric spell, you just need to try it when the time comes......

But the problem is storage.

Don couldn't get a high-pressure storage tank to store the gas he was making......

So you can only use the simplest way, blowing, blowing in a lot of air.

"As for why quicklime is blown in, it is so that the impurities in these melted liquids can coagulate together to form slag and discharge, see? Those tumbling things up there? Those are quicklime slag. ”

Don motioned to Brian to see the slag clearly, and with the stirring of the mage's hand, many lumps floated on top of the molten iron, Brian took a closer look, and was stunned: "These pig iron ingots were fired by me and Edgar, and there are so many impurities in them?" ”

"Of course, many things are not visible to the eye, but that doesn't mean they don't exist."

Don shrugged, his eyes fixed on the flames above the molten iron, and when the flames weakened and became weak, Don filtered out all the slag - a very easy way to do this with spells.

In fact, the process of steelmaking is far more complicated than these, but Don himself only remembers a few of them, and he really can't recall the other complicated processes.

After continuing to stir the molten iron to allow the toner and iron to fully react, Don was ready to set the shape.

As for other processes...... Hehe.

After the magic flame stopped, the molten iron was restrained by Donn's magic and turned into a square shape, and after cooling, it was neatly arranged.

Brian leaned in and touched it: "Big brother, this is steel?" ”

"Well, probably—"

Because his memory was too vague and unprofessional, Don wasn't sure if his attempt was successful, but of course he couldn't lose face in front of Brian, so he smiled proudly and waved his hand, "-Of course!" To be precise, it's a carbon-iron alloy, but ...... You don't have to care about the name, it's steel, well, yes, it has to be steel! ”

"But it looks no different from a pig iron ingot."

"The difference is huge...... Go back and try it out of these steels to build a few weapons. ”

Don manually refined dozens of kilograms of "steel" this time, which was enough for Brian to experiment.

"No problem!"

Brian was interested in experimenting with new materials, and he was eager to know how good the "carbon-iron alloy" Downe was talking about.

The two began to return home, and Tang En pondered all the way, if this could make some steel that could be put into use, then the steel mill could consider starting construction, and before that, the problem that still needed to be solved was how ordinary workers could achieve several more important technological means in the middle.

Blowing charcoal and lime can be achieved with constant magic aids, slag removal can also be achieved with high-temperature resistant magic metal tools, and stirring can be achieved by adding a magic circle to the bottom of the steelmaking furnace and controlling the output of mana through a simplified switch on the outside......

After going through the process in his mind, Don let out a long sigh of relief, with his poor knowledge reserves, he could only go so far, if even what he refined was that kind of scrap steel, he could only consider other means - Plandal is a magical world, and it is normal to make some strange special alloys, maybe there are better alloy materials than steel?

Immediately after returning to Ellington, Brian began experimenting with the properties of the steel. ===PS: I almost forgot to update...... After reading the vote~~~~
