The Ominous Lord of the Skaven

Chapter 190: Hammering the Furnace!

Large-scale iron smelting is imminent. After issuing an order to the Ministry of Industry to "work overtime and run at full capacity!", Ickert will devote himself to the iron smelting business again.

However, facing technologies outside his professional field, even Ickert also found it very difficult.

To be honest, in the process of ironmaking, all Ickert can do is to improve the existing ironmaking technology.

The hammer head of the Ministry of Industry was therefore brought up by Ickert. When this guy was blacksmithing in the village, he had experience in making iron himself.

"My lord, before we can smelt iron, we first need to burn some charcoal."

As Hammerhead said, he selected some good firewood from the timber in the territory.

Then he dug out a shallow pit with a few apprentice mice, and put a lot of wood into it.

Then ignite all the wood, and then backfill the shallow pit with the excavated loose soil, so that the wood will be simmered into charcoal in the pit.

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

But the problem is that due to the backward productivity of the times, raw materials such as coal are not only mined infrequently, but also expensive to sell and transported far away.

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

Fortunately, there is no shortage of wood here.

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

This is all learned in high school.

Thinking about it this way, education in a certain big country is simply a one-stop process of rebuilding industry, solving all the theoretical foundation problems along the way.

Generally, hematite (ferrous oxide) is reduced to iron and carbon dioxide by carbon monoxide produced in ironmaking furnaces.

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

This is also what Eckert needs to solve.

During the charcoal firing process, Ikett and Hammerhead were not idle. They collected some clay from the river bank, sifted out the stones, and mixed it into the river water to make mud.

That's not all, they added some crushed weeds to the mud and kneaded it evenly.

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

Just like when firing porcelain, iron-making kilns will also crack when they smelt iron at high temperature. This is due to the extrusion problem caused by thermal expansion and contraction of the brittle kiln body at high temperature.

After the grass is added, the iron kiln will produce some pores during the firing process (the weeds are burned into carbon), which can solve the problem caused by the rapid thermal expansion and contraction to a certain extent.

Like the gap between railroad tracks.

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

The next steps came naturally. Hammer found an open space, built a blast furnace with mud along the side, dug a lower opening for slag discharge, and opened the upper part completely for carbon dioxide discharge (in fact, using this ghost material can also can't close the mouth), there is also an opening for blowing air.

Such a blast furnace needs to be baked in the sun now, and then needs to add fire to the inner wall of the furnace for baking, which is very time-consuming.

If after this step is completed, the blast furnace is not cracked, or it is successfully repaired and perfected, then the crushed iron ore, limestone (calcium carbonate), and charcoal can be put into the blast furnace according to the ratio of experience.

Then there is burning, burning hard, nothing else.

Of course, due to the wide opening and the low efficiency of manpower blowing, the temperature of the blast furnace is actually very touching, and it is impossible to melt iron ore into molten iron.

At this time, in the fiery blast furnace, calcium carbonate is heated and decomposed to form calcium oxide and carbon dioxide (still only used high school knowledge), and lime further reacts with carbon to form calcium carbide and carbon monoxide, and carbon monoxide is then oxidized and iron is reduced to form iron and carbon dioxide.

Excess calcium oxide reacts with other impurities to form calcium salts, which settle to the bottom of the blast furnace.

These things will stay out of the slag outlet.

The smelted iron cannot be left in the form of molten iron because of the too low furnace temperature (about [-] degrees Celsius), and can only be formed into lump iron.

In the end, Ickert needs to smash the blast furnace that he has worked so hard to create after spending a lot of time and complicated steps!
That's right!Although he knew that this was a technical limitation, when Ickert saw that the hammer was about to go dry with a sledgehammer, he was really upset.

If you say that the production efficiency is low, let’s just lower it. This stove can’t be reused. It hasn’t been long since sentimental iron smelting, and all the time and energy have been used to make the stove!

"Leave the furnace under the hammer!"

Ickert yelled, which made Hammer put down the big hammer in his hand and kept the blast furnace.

"My lord, why can't you hammer it? If you don't smash this stove, you can't get iron!"

Hammer wondered, the territory was too extravagant before, and every day he either seized other people's iron or large steel plates, so smelting would naturally yield a lot of raw materials.

This also made the people ignore the hard-won steel, which is also the reason why the emperor only gave iron ore, but not iron.

Who has the kung fu to help others practice!Refined and too expensive!
Forged steel is more expensive!

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

Using magic to smelt iron is not the first initiative of Ikert. For high-level magicians, they have a unique method of smelting iron.

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

The sage who first invented the method described the technique this way - "I feel like I'm breaking something hard".

Looking back now, Ickert knows how the sages did it.

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

Fortunately, the sages haven't been perverted enough to "scrape iron" on a large scale, otherwise Ickert would have to think about whether to explore antimatter and dark energy in his daily practice.

Tucao to Tucao, what Ickert is going to do now is still incompatible with those advanced things, he just wants to use the magic power of flames to increase the temperature of the furnace.

As a fourth-level wind and fire dual-line mage, the mere furnace temperature is really hard for Ikett.

It's just that when he ignited a raging flame in the blast furnace confidently, the delicate mud tile structure could no longer withstand the mighty power of magic!

The blast furnace cracked open.

No way, it's too hot!

If Eckert had a system, the following sentence would probably pop up in his mind at this time:

"Drip, there is a lack of front-end technology [refractory bricks]."

This is the damn industry of human beings. Behind every seemingly simple technological device, there is an inconspicuous but indispensable front-end technology.

"."

Ickert finally realized his own insignificance at this time. Although he has solved many industrial problems so far, this road of equipment and weapon strengthening, which is comparable to krypton gold in online games, has actually just begun.

　Chapter 180 The eighth chapter is still closed in the small black room, I will try to restore it.

　　The general plot is that, in front of all the rats, Ickert molested the rats who didn't study hard, and set off a frenzy of learning in the territory.
