Although he was going to take Brian to try steelmaking, Tang En was confused in fact. In short, he took Brian to get some limestone first, then ran to the charcoal factory to get a batch of charcoal, and then found a place with no one on the edge of the forest to start construction.

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

Brian watched Tang En squatting there and studying the stones, with a look of entanglement. He clearly asked me to come and study, but he couldn't even understand it. He was still a fucking master!

“Fired limestone.”

"limestone?"

"Here, these are these stones."

Tang En pointed to the few limestones next to him: "Steelmaking requires quicklime, which will calcinate at high temperatures to produce quicklime and a gas."

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

The Ambris Mountains itself is a super huge vein. In addition, the dwarves dig it up and down, it is normal for a lot of limestone to be a lot.

"Oh, then remember it. This kind of stone is indispensable when making steel."

After Tang En finished speaking, he probably remembered it almost the same. With a casual hook, the mage grabbed the limestones and floated up. Then a thought flashed through, and a cluster of hot flames suddenly popped out of the air.

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

Brian was very surprised: "Seeing your battle situation before, I always thought you were a warrior!"

"Don't tell anyone."

Tang En said casually, but his eyes were fixed on the limestone, and the temperature of the flames kept rising.

"Why?"

Brian scratched his head: "Magics are much more popular than warriors. If your people know that you are a magician, they will probably worship you more and be more obedient. If I were to tell them, why do you keep it secret? Do you want to keep it mysterious? Or do you have enemies? Or—"

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

Tang En looked entangled. Brian was active in working, fighting, and was pretty good at being a friend. It was fine, but why did he talk so much? Especially after drinking, he was talking nonsense like a dam that opened the gate...

Brian said with confidence: "How can you forbid me from speaking? Speaking is given to us by the goddess-"

Silence technique.

Don't have his lips moved slightly, and Brian's voice disappeared instantly.

Huh? Why is there no sound?

Brian touched his lips and opened his mouth again, but still didn't make any sound. He suddenly became anxious and started roaring desperately at the top of his throat, but unfortunately he still didn't make any sound.

Tang En was too lazy to pay attention to him and focused on calcining limestone.

Soon the color of limestone turned white. With a light wave of the mage's hand, a layer of dusty calcium oxide fell on it, which is the so-called 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, Don looked back at Brian, but almost laughed out loud.

This guy actually opened his mouth and dug it up with his hands. Do you think something was wrong with his throat?

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

"Big brother, I—Huh!? Can speak! Damn—it's your spell!"

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

"This is when the spell comes into play."

Tang En said with a stern face: "Do you still want to continue watching?"

"I--"

Brian said dejectedly: "Okay, you won!"

Brian originally wanted to fight Tang En to have a good time, but after thinking about it carefully, Tang En couldn't fight too much in melee, and now he knows that he is still a mage, so how can he fight?

Then Tang En pointed to the pile of quicklime and said, "Did you see, these are quicklime."

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

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

Tang En said: "This thing turns into ripe lime after encountering water, and it will also release a lot of heat, which is very dangerous."

"Oh? Wouldn't it be great if you were fighting in the bardo?"

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

Speaking of which, when we first saw the Deer and the Cauldron, Wei Xiaobao killed many enemies with the magic weapon of quicklime. It can be seen how powerful the quicklime is. People here in Prandal have never seen quicklime, so they definitely don’t know how to deal with quicklime. If this big killer suddenly is used in the battle...

Tang En murmured this and said, "The quicklime and charcoal are ready, and now it's time to make steel."

"How to practice?"

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

Tang En said as he took out some pig iron ingots, and the magic flames instantly burst out with a high temperature of more than 2,000 degrees. In a short while, the pig iron ingots melted into melting fluid.

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

Coke is commonly used in steelmaking on earth. Coke is distilled from coal mines at high temperature and high pressure. At present, Tangen has never heard of coal mines in Plandal, so he naturally would not consider coke. But then again, charcoal is actually better for steelmaking. Although charcoal consumes a lot,... aren't the endless Lady forest and Emerald Forest next to Ellington the best source of charcoal?

Just use it and plant it as you like, and don't mess with the elves...

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

"Because iron is not pure, what should I explain if I wipe it?"

Don En was confused. Should he share 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..."

Tang En originally wanted to talk about redox reactions, but he could see Brian's dull look, so he decided to forget it.

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

When blowing charcoal, in order to increase the degree of reduction, Tang En also used wind-type spell to blow a lot of air into the melt - it should have been blown in pure oxygen, but Tang En can't make the raw materials for storage gas...

It is easy to make pure oxygen. I made an electrolyzer to electrolyze pure water. The gas from the cathode is hydrogen and the gas from the anode is oxygen. Even if I don’t know which side of the cathode is used to use the electric spell is the cathode and which side of the anode is, I just try it out then...

But the problem is still storage.

Tang En can't get a high-pressure storage tank to store the produced gas now...

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

"As for why quicklime is blown in, it is to allow the impurities in these melt liquid to condense together to form slag and discharge it. Look, do you see? The rolling things on it? Those are the slags that quicklime turns into."

Tang An signaled Brian to see the slag clearly. As the mage's hand stirred, many blocks floated on the iron. Brian looked carefully and was stunned: "These cast iron ingots were made by Edgar and I, and there were so many impurities in it?"

"Of course, many things cannot be seen by the eyes, but they do not mean they do not exist."

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

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

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

As for other process processing...haha.

After the magic flames stopped, the iron water was bound by Tang En's magic and turned into square shapes. After cooling down, it was neatly arranged.

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

"Well, probably-"

Because the memory is too vague and unprofessional, Tang En was not sure whether his attempt was successful. However, of course he could not lose face in front of Brian. He smiled proudly and waved his hand, "—Of course it's! To be precise, it's carbon ferroalloy, but... you don't have to care about this name, this is steel, well, yes, it must be steel!"

"But it looks like there is no difference between it and cast iron ingot."

"The difference is big... When you go back, you can use these steel to create a few weapons."

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 testing new materials. He really wants to know how superior the performance of this "carbon ferroalloy" that Tang En mentioned.

The two started to return, and Tang En was pondering all the way. If this could be used to refine some practical steel, the steel mill could consider starting construction. Before that, the problem that needs to be solved is how ordinary workers should implement several more important craftsmanship methods in the middle.

Carbon and lime blowing can use auxiliary tools that are constant magic, and slag discharge can also be achieved by using high-temperature-resistant magic metal manufacturing tools. If you want to stir, you can consider adding a magic array to the bottom of the steelmaking furnace, and use an external simplified switch to control the output of magic to achieve...

After roughly passing the process in his mind, Tang En breathed a long sigh of relief. With his pitiful knowledge reserve, he could only achieve this level. If even the scrap steel he made was the kind of scrap steel, he could only consider other methods - Plandal is a magical world, and it is normal to create some strange special alloys. Maybe there is an alloy material better than steel?
