Things From Another World

74. Chapter 74 Basic Chemistry is popular…

Although it was said to bring Brian to try steelmaking, in fact, Dunn couldn’t figure it out. In short, he took Bryan to get some limestone and then went to the charcoal factory to get a batch of charcoal. After that, I found a place on the edge of the forest where no one was going to start work.

“Big brother, what are you going to do?”

Brian looked at Dunn and studied the stone there. His face was tangled and he told himself to come and watch the study, but he couldn’t read it and he learned a hair!

“Burning limestone.”

“limestone?”

“Oh, these stones.”

Dunn pointed to a few pieces of limestone next to it: “Slag making requires the use of quicklime, which is calcined at high temperatures to produce quicklime and a gas.”

“This stone? We are all over the land.”

The Anbris Mountains themselves are a super-large vein, and the dwarves dig and dig them up.

“Oh, then you remember, steel is essential if you make steel.”

Dunn finished, probably recalled almost, he took a hand, the Master’s hand grabbed the limestones floating up, and then a thought flashed, a burst of hot flames in the air.

“Hey!? Big brother, are you a magician?”

Brian was very surprised: “I saw you fighting before, I always thought you were a warrior!”

“Don’t tell others.”

Dunn whispered, his eyes fixed on limestone, and the temperature of the flame kept rising.

“why?”

Brian scratched his head: “The magician is much more popular than the warrior. If your people know that you are a magician, they are more admired and obedient to you. If I am, I will tell them, why are you? Want to be secret? Do you want to keep mystery? Or do you have an enemy? Or say-“

“If you talk nonsense, give me a go!”

Dunn’s face is tangled. This Brian is active, active, and very good. When a friend is completely okay, why is it so much? Especially after drinking the wine, it’s just like the dam that opened the gate…

Brian said with conviction: “How can you stop me from speaking? The words are given to us by the goddess-“

Silence.

Dunn’s lips moved, and Brian’s voice disappeared instantly.

Huh? Why is there no sound?

Brian touched his lips and opened his mouth again. He still didn’t make a sound. He suddenly rushed and screamed with a scorpion, but unfortunately it was still a little sound.

Dunn was too lazy to take care of him, and he devoted himself to calcining limestone.

Soon the color of the limestone turned white, and the wizard’s hand swayed gently, and a layer of dusty calcium oxide, also known as quicklime, fell on it.

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

After picking up the pile of lime, Dunn looked back at Brian, but almost laughed.

This guy was actually smeared with his mouth open in his mouth. Is it because of the problem?

Dunn lifted the silence and said: “The next time I talk nonsense, I will let you not talk for a day.”

“Big brother I – hey!? Can talk! Damn – is your spell!”

Brian suddenly got up: “You actually imprisoned my power to speak!”

“The spell is at this time.”

Dunn said with a slap in the face: “Do you still want to continue watching?”

“I–“

Brian said with a dejected head: “Okay, you won!”

Brian wanted to have a good time with Dunn. Think carefully, Dunn didn’t play much in the melee. Now he knows that he is still a mage. How can I fight this!

Dunn said that the pile of quicklime said: “If you see no, these are quicklime.”

Brian leaned over and looked at it: “I haven’t seen it.”

“It’s normal… don’t get together, it’s a big problem in your eyes.”

Dunn said: “This thing becomes ripe lime when it meets water, and it also emits a lot of heat, which is very dangerous.”

“Oh? If it wasn’t very good in the battle?”

Brian just said casually, Dunn had a bright eye and discovered another use of quicklime.

When I saw Lu Dingji, Wei Xiaobao killed a lot of enemies by relying on the magic of lime. It shows how powerful the lime is. The people here have not seen the lime. I don’t know how to deal with the quicklime. If it is suddenly in the battle. Sacrifice this big killer…

Dunn remembered this silently and said: “The quicklime and charcoal are all ready, and now you can make steel.”

“How to refine?”

“It was originally necessary to smelt the ore first, but in order to save trouble, I got some raw iron ingots from Edgar.”

Dunn said that some of the pig iron ingots were taken out, and the magical flame burst out with a temperature of more than two thousand degrees. In a little while, the raw iron ingots melted into a melt.

“After the melting of the pig iron, blow these charcoal and quicklime into the melt…”

Coke is commonly used in steelmaking on the earth. Coke is the high temperature and high pressure distillation of coal mines. At present, Dunn has not heard of coal mines in Plandal. Naturally, coke will not be considered. But then, charcoal for steelmaking. In fact, the effect is better. Although the consumption of charcoal is very large,… Is the endless Ladiya forest and emerald forest next to Ellington the best source of charcoal?

As long as you use it, don’t mess with the elf…

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

“Because iron is not pure, iron ore inside… I rub how should I explain?”

Dunn is tangled, 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 inside. The higher the temperature of fusion, the more complete the reaction…”

Dunn originally wanted to talk about the redox reaction. It can be seen that Brian’s face is sluggish, or decided to forget.

Anyway, his chemistry is only half the level of hang…

In order to increase the degree of reduction when blowing charcoal, Dunn also used wind-based spells to blow a lot of air into the melt – which should have been blown into pure oxygen, but Dunn can’t make a storage gas raw material at all… …

To make pure oxygen, it is better to say that an electrolyzer is used to electrolyze pure water. The gas of the cathode is hydrogen. The gas of the anode is oxygen. Even if you don’t know which side of the electromagnet is the cathode, which side is the anode, you just need to try it. Up…

But the problem is still storage.

Dunn has no way to make a high-pressure storage tank to store the gas produced…

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

“As for why the quicklime is blown in order to allow the impurities in these melts to condense together to form a slag discharge, hey, see the things that are tumbling above? Those are the slag of quicklime.”

Dunn signaled Brian to see the slag. With the stirring of the Master’s hand, many pieces floated on the molten iron. Brian looked at it and suddenly said: “These iron ingots were fired with Edgar. There are so many impurities inside?”

“Of course, a lot of things can’t be seen by the eyes, but it doesn’t mean they don’t exist.”

Dunn shrugged, his eyes fixed on the flames above the molten iron, and when the flames weakened and became weak, Dunn filtered out all the slag – it was easy to do so using spells.

In fact, the process of steelmaking is much more complicated than these, but Dunn himself only remembers this. Other complicated processes can’t be remembered.

After continuing to stir the molten iron to allow the toner and iron to react fully, Dunn intended to set it.

As for other process processing…hehe.

After the magic flame stopped, the molten iron was constrained by Dunn’s magic to become a square shape, and after cooling, it was placed neatly.

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

“Well, probably?”

Because the memory is too vague and unprofessional, Dunn is not sure whether he has succeeded in this attempt, but of course he can’t lose face in front of Brian. He smiles proudly and waved his hand. “- Of course it is! Accurately said It’s carbon-iron alloy, but… you don’t care about this name, this is steel, um, yes, it must be steel!”

“But looking at it is no different from a raw iron ingot.”

“The difference is big… Go back and try to build a few weapons with these steels.”

Dunn manually refining dozens of kilograms of “steel” this time, but it was enough for Brian to experiment.

“no problem!”

Brian’s interest in experimenting with new materials is quite large, and he is keen to know what superior performance Dunn said of this “carbon iron alloy”.

The two started to return, and Dunn was thinking about it all the way. If he could refine some steel that could be put into practical use, then the steel mill could consider starting construction. Before that, the problem that needs to be solved was ordinary. How do workers achieve several important processes in the middle?

Blowing carbon and lime can use constant magical aids, and slagging can also be done with high-temperature magic metal manufacturing tools. Stirring can be considered by adding a magic array to the bottom of the steelmaking furnace, controlled by a simplified external switch. Magic output to achieve…

After roughly going through the process in his mind, Dunn sighed with a long sigh of relief, and with his poor knowledge reserves, he could only do this. If he even produced the kind of scrap, You can 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?

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