Chapter 190 The hammer is placed on the furnace!

Large-scale iron smelting is urgent. After issuing the order to the Ministry of Industry to "work overtime and operate with all your strength!", Ictor is going to devote himself to the iron smelting industry again.

However, when faced with technology outside of his professional field, Rashi Ictor also felt very difficult.

To be honest, in the process of iron smelting, all Ictor can do is to improve the existing iron smelting technology.

The hammer of the Ministry of Industry was therefore brought out by Ictor. This guy had his own experience in smuggling iron when he was in the village.

"Lord, before smelting iron, we first need to burn some charcoal."

Hammerhead said, picking some good firewood from the wood in the territory.

Then he took a few apprentice mice to dig out a shallow pit and put a large amount of wood into it.

Then ignite all the wood, and then use the excavated loose soil to backfill the shallow pit, so that the wood can be stewed into charcoal.

This process often takes several days, and it will definitely be faster if coal is used or coke is burned.

Before this was over, they added some broken weeds to the mud and rubbed them evenly.

But when he was confident that he ignited the blast furnace, the delicate mud structure could no longer withstand the power of magic!

Generally speaking, hematite (iron trioxide) is reduced to iron and carbon dioxide through carbon monoxide produced in iron smelting furnaces.

This is the damn industry of human beings. After every seemingly simple technological device, there are inconspicuous and indispensable pre-tech technologies.

As a fourth-level wind and fire dual-type mage, Iket is really hard to deal with just the furnace temperature.

I really don’t know how these natives discovered this method.

These things will be left out from the scum.

"Did, lack of front-mounted technology [refractory bricks]."

The excess calcium oxide will react with other impurities to form calcium salts and precipitate to the bottom of the blast furnace.

"Ahem, I asked you to stop to test the power of magic."

After adding broken grass, some fine pores will be produced during the firing process of the iron smelting kiln (weeds are burned into carbon), which can solve the problems caused by rapid thermal expansion and contraction to a certain extent.

Fortunately, the sages have not been so perverted that they can "pull iron" on a large scale, otherwise Ictor would have to think about whether he should explore antimatter and dark energy in his daily practice.

Looking back now, Ictor knew how the sages did it.

The melted iron cannot be retained in the form of molten iron because of the low furnace temperature (about 800 degrees Celsius), so it can only form a block of iron smelting.

The first sage to invent this method described this technique in this way - "I feel like I've broken something apart."

There is no way, it's too burning!

This is just like when burning porcelain. Iron smelting kilns will crack when smelting iron at high temperatures. This is due to the extrusion problem caused by the heat expansion and contraction of the kiln bodies with high temperatures.

This also made the leaders ignore the hard-earned steel, and it is also the reason why the emperor only gave iron ore but not iron.

The blast furnace cracked.

Ictor shouted, and then the hammerhead put down the big hammer in his hand and saved the blast furnace.

During the charcoal burning process, Ictor and Hammerhead were not idle either. They collected some clay on the bank of the river, sifted out the stones, and mixed them into the river water and made them into mud.

It is not difficult for Ictor to analyze the effect of adding weeds.

At the end, Ictor needed to smash the blast furnace that he had been working hard and spent a lot of time and complicated steps to create!

That's right! Although I knew this was a technical limitation, Ictor felt really uncomfortable when he saw the hammer head swinging the sledgehammer and about to start to dry.

"Have the furnace under the hammer!"

This was learned in high school.

No matter how much he complained, what Ictor is going to do now is nothing to do with those advanced things. He just wanted to use the magic of flame to increase the furnace temperature.

"Lord, why can't you hammer it? You won't get iron if you don't smash this stove!"

If Iket had a system, this sentence would probably pop up in my mind:

At this time, in the hot blast furnace, calcium carbonate is heat-decomposed to form calcium oxide and carbon dioxide (although only high school knowledge is used), and lime further reacts with carbon to produce calcium carbide and carbon monoxide. The carbon monoxide then trioxides and reduces iron to form iron and carbon dioxide.

If the blast furnace does not crack or is successfully repaired and improved after this step is completed, the crushed iron ore, limestone (calcium carbonate), and charcoal can be placed in the blast furnace according to the proportions in experience.

Using magic to smelter iron is not the first to Ictor. For advanced magicians, they have a unique method of smelting iron.

Who has the skill to help others practice! It’s expensive to practice!

Forged steel is more expensive!

It's like a gap between railroad tracks.

What's more, Windersol's trade route has not been opened, so if you want to use charcoal, you still have to burn it.

Fortunately, there is no shortage of wood here.

Then it was burned, and it was hard, nothing else.

Such blast furnaces need to be made in the sun, and then fire is added to the inner wall of the furnace for baking, which is very time-consuming.

Due to its unique production process, this method is also called "soft iron".

Of course, due to this wide exposure and the low efficiency of manpower blowing, the blast furnace temperature is actually very touching and cannot melt the iron ore into molten iron.

He broke the chemical bond! That was a strong interaction force!

You say that the production efficiency is low, it is a little lower. This furnace cannot be reused. It hasn't been long since the relationship smelted, and time and energy have been spent on building the furnace!

But the problem is that due to the backward productivity of the times, raw materials such as coal are not only exploited less, but also sold more expensively, and the transportation distance is still long.

This is what Ictor needs to solve.

The next steps were natural. The hammer head found an open space, built a blast furnace with mud along the edge, dug out a lower opening for slag discharge, and the upper part was completely open for venting carbon dioxide (in fact, it was impossible to use this ghost material), and there was an opening for blowing.

According to known methods, carbon is indispensable in iron smelting, because iron smelting is ultimately a reduction course in chemical reactions.

In terms of restoration methods, there is not much difference between modern and ancient times, but the difference lies in the equipment.

Hammerhead wondered, the territory was too luxurious before, and either seized other people's iron tools or large steel plates every day. There were many raw materials obtained by smelting this way.

Thinking of this, the education of a major country is simply a one-stop reconstruction of industry and solving all the theoretical basic problems along the way.

"."

Ictor finally realized his insignificance at this time. Although he had solved many industrial problems so far, this path comparable to the strengthening of Krypton gold equipment and weapons in the online game has actually just begun.

Chapter 188: I am still in the dark room, so I will try to recover.

The general plot is that Ictor turns into a rat that does not study hard in front of the rats, and set off a craze for learning in the territory.
Chapter completed!
