Chapter 72 (2/2)

In addition to blowing carbon, steel-making also needs quicklime, which is fired from limestone. Limestone is dug everywhere in the iron ore mountain in Brussels. He has ordered Rogers to leave those limestone.

Rogers told Donne that Rex had even worried about how to deal with the stones before, but he didn't expect that Donne asked them to transport the stones to Ellington.

Donne didn't explain at that time. Now there is a large amount of limestone piled up outside with the iron ore.

There is also a production line for firing quicklime, but don doesn't know what it looks like. He doesn't bother to make so much trouble. Limestone calcined at high temperature will decompose into calcium oxide and carbon dioxide, and calcium oxide is the so-called quicklime. As long as he knows this principle and can solve problems by magic, he will never burn his brain again.

The problem of quicklime is very easy to solve. The main problem perplexing Donne is the problem of steelmaking furnace.

Donne's impression that the steelmaking furnace used in medium and large factories seems to be called a converter? But he has no idea what the converter is

But he knows a little.

However, whether it is a converter or a blast furnace, the main technical difficulty to be solved is the problem of temperature and slag discharge, but this problem... Is not a problem at all in prandal.

Temperature? Donne estimated that the high-order fire magic temperature he released could easily reach more than 10000 degrees... For steelmaking? Don't be funny. It's estimated that the iron ore will be gasified directly.

The temperature of steelmaking can be easily solved with fire magic array.

As for slag removal, arcane magic has a miraculous effect here... It can clean up the residue inside without affecting the molten steel.

Instead of having a headache, it's better to have a headache about how to let ordinary workers complete these steps.

Maybe... You can recruit some mages to do this?

As soon as Tang en thought of this method, he laughed. Prandal's magicians are generally proud. How can they do this kind of work?

Unless

Unless you cultivate some magicians yourself.

”... Lord? Lord!”

Fiona called several times, and Donne came back: ”what's up?”

”Do you have anything else to do? If not, I'll work!”

”No, no...”

So Donne was driven out of his study by Fiona.

”Really, who dares to ask after such a bad temper...”

Donne subconsciously complained.

”Bang!”

Something seemed to have hit the door in the study, and Donne ran away at once.

”Blast furnace... Um... Blast furnace...”

Donne thought hard for a long time, but he didn't think of the specific structure of the blast furnace. Finally, he simply patted his head and ran to find Brian.

”Remove impurities?”

Brian was stunned when he suddenly heard this question: ”there is no special means, that is, normal melting, mold cooling, melting and forging again when necessary.”

”But it's wrong...”

Donne frowned. Generally, the quality of products forged by dwarves is better than that produced by human blacksmiths, but on the one hand, technology is also material. Technology can not completely solve the defects of materials.

”Melt... Into the mold... Merge again... And so on!”

Donne suddenly had a flash of inspiration: ”I remember you despised the dwarves living in human cities and said that their skills were getting worse and worse?”

”That's right.”

Brian looked puzzled. He told Donne casually when he was drunk last time. Why did he mention it at this time?

Donne seemed to touch the point: ”I remember there is a crater under forge hammer castle. The furnace used by your dwarves will use the lava from the crater to continuously heat. At the same time, runes dwarves will lay down flame runes to gather fire elements, right?”

Brian suddenly widened his eyes: ”damn - big brother, how can you know this!?”

Brian never told Donne about the situation in forge hammer castle, let alone the secret of Rune dwarves. This is the top secret information of the dwarf country!

No other race knows about it!

Donne doesn't wonder why Brian is so excited. In the eyes of the aborigines, dwarves are a pure warrior race. Dwarves have no other occupation except soldiers, priests and paladins who believe in the Earth Goddess.

However, there are mages among the dwarves.

According to the internal rumors of the dwarves, they are the children of runes blessed by the Earth Goddess and born with magic, so these rare dwarves are called Rune dwarves.

However, this is not the most important thing.

The most important thing is the great significance of Rune dwarves to dwarves - although Rune dwarves may not be all divine craftsmen, divine craftsmen are Rune dwarves=== PS: please vote after reading~~~~
