Chapter 74 When the Popularization of Basic Chemistry Is in Progress...

Although he said that he wanted to take Brian to try steelmaking, Tang En was at a loss as to how to do it. In short, he first took Brian to get some limestone, and then went to the charcoal factory to get a batch. Charcoal, and then I found a deserted place at the edge of the forest and planned to start work.

"Brother, what are you planning to do?"

Brian watched Tang En squatting there studying the stone with a troubled expression on his face. He clearly asked himself to watch and study, but he couldn't even understand it, so he was still learning!

"Fired limestone."

"limestone?"

"Here, these are the stones."

Tang En pointed to a few pieces of limestone next to him: "Steelmaking requires quicklime, and these limestones are calcined at high temperature to produce quicklime and a gas."

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

The Ambris Mountain Range itself is a super huge mine vein, and with the dwarves digging around, it is normal for there to be a lot of limestone.

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

After Tang En finished speaking, he probably had almost recalled it. He hooked it casually, and the mage's hand grabbed the limestones and floated up. Then a thought flashed, and a cluster of fiery flames suddenly appeared in the air.

"Huh!? Brother, are you a magician?"

Brian was very surprised: "I saw you fighting before, I always thought you were a fighter!"

"Don't tell anyone."

Tang En 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 do you Do you want to keep it a secret? Do you want to maintain a sense of mystery? Or do you have enemies? Or—”

"If you talk nonsense again, get out!"

Tang En's face was full of confusion. This Brian was active in his work and fights, and he was quite a nice person. It was no problem to be a friend, but why did he talk so much? Especially after drinking, it's like a dam that has opened its gates, and it's going on and on...

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

Silence.

Tang En's lips moved slightly, and Brian's voice disappeared instantly.

Huh? Why is there no sound?

Brian touched his lips, opened his mouth again, but still didn't make a sound, and suddenly became anxious, and roared desperately, but unfortunately, he still didn't make a sound.

Tang En didn't bother to talk to him, and concentrated on calcining the limestone on his own.

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

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

After putting away the pile of quicklime, Tang En looked back at Brian, but almost laughed out loud.

This guy opened his mouth wide and dug it up with his hands. Did he think there was something wrong with his throat?

Tang En lifted the silence technique, and said: "Next time you talk nonsense, I will make you unable to speak for a day."

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

Brian jumped up immediately: "You actually imprisoned my right to speak!"

"That's when the spell comes into play."

Tang En said with a straight face: "Are you planning to continue watching?"

"I--"

Brian said dejectedly, "Okay, you win!"

Bryan originally wanted to have a good fight with Tang En, but after thinking about it carefully, Tang En didn't fight much in close combat, and now that he knew he was still a mage, how could he fight like this!

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

Brian leaned over and took a look: "I haven't seen it."

"It's normal...don't get close to it, it will be a big trouble if it gets in your eyes."

Tang En said: "When this thing meets water, it will turn into slaked lime, and it will emit a lot of heat at the same time, which is very dangerous."

"Oh? Wouldn't it be nice to have a shady person in the battle?"

Brian just said it casually, but Tang En's eyes lit up, and he discovered another use of quicklime.

It is said that Wei Xiaobao used quicklime as a magic weapon to kill many enemies when he first read The Deer and Ding Ji. It can be seen how powerful quicklime is. The people here in Prandal have never seen quicklime, so they must not know how to deal with quicklime. Bring out this big killer...

Tang En silently remembered this, and then said: "The quicklime and charcoal are all ready, and now we can make steel."

"How to practice?"

"Originally, the ore should be smelted first, but to save trouble, I got some pig iron ingots from Edgar."

As Tang En spoke, he took out some pig iron ingots, and the magic flame instantly burst into a high temperature of more than 2,000 degrees, melting those pig iron ingots into a molten liquid in a short while.

"After the pig iron is melted, these charcoal and quicklime are blown into the melt..."

Coke is commonly used in steelmaking on the earth. Coke is produced by dry distillation of coal mines isolated from air at high temperature and high pressure. Tang En has not heard of coal mines in Prandal so far, so naturally he would not consider coke, but then again, steelmaking uses Charcoal is actually more effective. Although charcoal consumes a lot, isn't the boundless Ladia Forest and Emerald Forest next to Ellington the best source of charcoal?

As long as you use it and grow it, don't mess with the elves...

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

"Because the iron is not pure, in the iron ore...how can I explain it?"

Tang En was entangled, should he 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 melting temperature, the more fully the reaction..."

Tang En originally wanted to talk about oxidation-reduction reactions, but seeing Brian's sluggish expression, he decided to forget it.

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

When blowing in the charcoal, in order to increase the degree of reduction, Tang En also used a wind spell to blow a large amount of air into the melt - pure oxygen should have been blown in, but Tang En has no way to make stored gas now. raw material……

Making pure oxygen is easy to say. Make an electrolyzer to electrolyze pure water. The gas at the cathode is hydrogen and the gas at the anode is oxygen. up...

But the problem remains with storage.

Tang En has no way to get out a high-pressure storage tank to store the produced gas...

So I can only use the simplest method, blowing air, blowing in a lot of air.

"As for why the quicklime is blown in, it is to allow the impurities in the molten liquid to condense together to form slag to be discharged. Here, see? Those tumbling things above? Those are the slag turned from quicklime."

Tang En motioned Brian to look at the slag clearly. With the stirring of the mage's hand, many lumps floated on the molten iron. Brian took a closer look and was stunned: "These pig iron ingots were fired by me and Edgar together. Yes, there are so many impurities in it?"

"Of course, many things are invisible to the eyes, but that doesn't mean they don't exist."

Tang En shrugged his shoulders and kept his eyes on the flames above the molten iron. When the flames weakened and became faint, Tang En filtered out all the slag - this purpose can be easily achieved by using spells.

In fact, the steelmaking process is much more complicated than these, but Tang En himself only remembers this, and he really can't recall other complicated processes.

After continuing to stir the molten iron to allow the carbon powder and iron to fully react, Tang En planned to set the shape.

As for other crafting... huh.

After the magic flame stopped, the molten iron was restrained by Tang En's magic power and turned into square pieces. After cooling down, they were neatly arranged.

Brian went up to touch it: "Brother, is this steel?"

"Well, maybe—"

Because his memory was too vague and he was unprofessional, Tang En wasn't sure if his attempt was successful, but of course he couldn't lose face in front of Brian, he smiled proudly and waved his hand, "—Of course it is! Accurate Say, it’s a carbon-iron alloy, but...you don’t need to pay attention to the name, this is steel, um, yes, it must be steel!”

"But it looks no different from pig iron ingots."

"The difference is huge... Go back and try to forge a few weapons with these steels."

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

"no problem!"

Brian is quite interested in experimenting with new materials, and he really wants to know how superior the performance of this "carbon-iron alloy" that Dunn mentioned is.

The two started their return journey. Tang En was thinking all the way. If some steel that could be put into practical use could be produced in this way, then the steel factory could be considered to start construction. Before that, the problem that needs to be solved is How should ordinary workers realize several more important technological means in the middle.

Carbon blowing and lime can use auxiliary tools with constant magic, and slag removal can also be realized by using high-temperature-resistant magic metal manufacturing tools. Stirring can be considered to add a magic circle at the bottom of the steelmaking furnace, and control it through a simplified external switch The output of magic power to achieve...

After roughly going through the process in his mind, Tang En heaved a long sigh of relief. With his poor knowledge reserve, he could only do this. We can only consider other means - Prandal is a magical world, and it is normal to make some weird special alloys, maybe there are alloy materials better than steel?

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