Things from Another World

Although it was said that Brian was going to try steelmaking, in fact, Tang En had no idea what to do. In short, he took Brian to get some limestone, and then went to the charcoal factory to get a batch. Charcoal, and then found a place on the edge of the forest where no one was planning to start.

"Brother, what are you planning to do?"

Brian watched Tang En squatting there to study the stones, his face was tangled, he obviously called himself to study by himself, but he could n’t understand it, and learned a hair!

"Burned limestone."

"limestone?"

"Well, these are the stones."

Down pointed to a few pieces of limestone next to it: "Steel is needed for steelmaking. These limestones are calcined at high temperatures to produce quick lime and a gas."

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

The Ambries itself is a super huge vein. In addition, the dwarves dug and digged, many limestones are normal.

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

After Tang En said it, he probably remembered it. He hooked it, and the mage's hand grabbed the limestone and floated, then a thought flashed, and a burst of hot flames burst out in the air.

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

Brian was very surprised: "Looking at your fighting before, I always thought you were a soldier!"

"Don't tell others."

Tang En said casually, but his eyes were staring at the limestone, and the temperature of the flame kept rising.

"why?"

Brian scratched his head: "Magic is more popular than warriors. If your people know that you are a magician, they may adore you more and be more obedient. If I were to say it, I would definitely tell them why you are. Keep it secret? Do you want to keep it mysterious? Or do you have enemies? Or say— "

"Fuck me off if you stop talking nonsense!"

Tang En's face was tangled. This Bryan was active in work, active in fights, and very nice. When he was a friend, there was no problem at all, but why was there so much? Especially after drinking, it is almost endless like the dam that opened the gate ...

Brian said rightly, "How can you stop me from speaking? But the goddess has given us—"

Silence.

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

Huh? Why is there no sound?

Brian touched his lips, opened his mouth again, and still didn't make a sound. He was in a hurry immediately, and shouted desperately, but unfortunately still no sound came out.

Tang En didn't bother to ignore him, and focused on calcining the limestone.

Soon the color of limestone turned white, and the Master's hand lightly shook, and a layer of dust-like calcium oxide fell on it, also known as quicklime.

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

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

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

Tang En lifted the silence and said, "Next time you talk nonsense, I will keep you from talking for a day."

"Big brother me-eh !? Can talk! Damn-it's your spell!"

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

"Spells come into play at this time."

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

"I--"

Brian said downcast, "Well, you won!"

Brian wanted to have a good fight with Tang En, but if you think about it, Tang En won't fight too much in melee. Now that he knows he is still a mage, how can he fight it!

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

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

"It's normal ... don't go up, it's too much trouble in your eyes."

"This thing turns into lime when it gets into water," Tang said. "It also emits a lot of heat, which is dangerous."

"Oh? Wouldn't it be nice if the yin was in battle?"

Brian just said casually, but Dunn's eyes brightened and he found another use of quicklime.

When I first saw Lu Dingji, Wei Xiaobao used the magic weapon of quick lime to kill a lot of enemies. It can be seen how powerful the quick lime is. People in Prendall have never seen quick lime. I definitely do n’t know how to deal with quick lime. Sacrifice this big killer ...

Tang En silently noted this, and then said, "Lime and charcoal are ready, and steel can now be made."

"How to make it?"

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

Tang En said, taking out some pig iron ingots, the magic flame burst into a high temperature of more than 2,000 degrees in an instant, and after a short time, the pig iron ingots were melted into a melt.

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

Coke is commonly used in steelmaking on the earth, and coke is carbonized from high-temperature and high-pressure distillation of coal from insulated coal. At present Tang En has not heard of a coal mine in Prandall. Naturally, coke is not considered, but then again, steelmaking Charcoal is actually more effective. Although the consumption of charcoal is large, but ... the endless Ladiya Forest and Emerald Forest next to Ellington are not the best source of charcoal?

Just use whatever you like, don't mess with the elves ...

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

"Because iron is not pure, inside the iron ore ... how can I explain what I rub?"

Tang En is entangled. Is it necessary 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. The higher the temperature of fusion, the more fully the reaction ..."

Tang En originally wanted to talk about the redox reaction, depending on Brian's dull look, he decided to forget it.

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

When blowing charcoal, in order to increase the degree of reduction, Tang En also used wind spells to blow a large amount of air into the melt-it should have been blowing pure oxygen, but Tang En can't make storage gas at all now. raw material……

It ’s easy to make pure oxygen. An electrolyzer is used to electrolyze pure water. The gas in the cathode is hydrogen and the gas in the anode is oxygen. Now ...

But the problem is still in storage.

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

So you can only use the simplest method to blow air and blow in a lot of air.

"As for why the quicklime is blown in, so that the impurities in these melts can condense together to form **** discharge, huh, see? The things that are rolling above? Those are the slags that turn into lime."

Dean motioned to Brian to see the slag, and as the mage's hand stirred, many pieces floated on the molten iron. Brian took a closer look and suddenly said: "I burned these pig iron ingots with Edgar Yes, there are so many impurities in it? "

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

Tang En shrugged, and kept staring at the flames above the molten iron. When the flames weakened and became weak, Tang En filtered out all the slag-using spells can easily achieve this purpose.

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

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

As for other processes ... hehe.

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

Brian rushed up and touched, "Brother, is this steel?"

"Well, probably--"

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

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

"The difference is big ... go back and make a few weapons with these steels and try them."

This time Tang En refined dozens of kilograms of "steel" by hand, which was enough for Brian's experiment.

"no problem!"

Bryan's interest in experimenting with new materials is quite great, and he really wants to know how superior the "carbon iron alloy" that Tangen calls it.

The two began to return. Tang En was meditating along the way. If this could produce some steel that can be put into practical use, then the steel mill can consider building it. Before that, the problem that needs to be solved is How should ordinary workers realize some of the more important technological means in the middle.

Carbon and lime can be blown with auxiliary tools with constant magic, and **** removal can also be achieved with high temperature resistant magic metal manufacturing tools. Stirring can be considered by adding a magic array to the bottom of the steelmaking furnace and controlling it with a simplified switch on the outside The output of magic to achieve ...

After roughly going through the process in his mind, Tang En breathed a long sigh of relief. With his poor knowledge reserve, he could only do so. If even the scrap steel he made was the same, Only other means can be considered-Prandall is a magical world, and it is also normal to make strange and strange special alloys. Maybe there are better alloy materials than steel?

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