As we all know, the main differences between pig iron (cast iron), wrought iron, and steel focus on carbon. The carbon content of pig iron is the highest, followed by steel, and that of wrought iron is the lowest.

According to the different carbon content, steel is also divided into low carbon steel, medium carbon steel and low carbon steel.

It can also be seen from this that steelmaking and ironmaking is essentially a process of competing with carbon.

As a mechanical dog, the above are all familiar knowledge. As a passing dog in mechanical dogs, this is the basic skill in basic skills, which must be mastered and skillfully applied.

If the steel can''t be refined, what kind of field is it? It''s better to wipe your neck and see if you have a chance to wear it back.

Please note that this is not a shame, but a sincere proposal.

Because according to the rule of crossing the alien world, most of the passers-by will face many dangers, and even there are a lot of unfortunate people who have been killed in the first place.

There are only a few passers-by who can wait to die. If you read a hundred books, you may not find one.

What should we do?

Self improvement!

Steelmaking and ironmaking is the first step of self-improvement and also the first cry of the farming party.

Only by refining steel and iron, can we have a chance to keep our underwear and not lose miserably; if we want to mix better, we must refine good steel and iron, so that we can burst the enemy''s ribs and pierce the enemy''s skull.

Otherwise, the consequences, you know, will definitely die very ugly.

Suicide, on the one hand, can avoid the pain and humiliation of being beaten by the enemy, on the other hand, can also fight against the chance of reverse wear.

Due to the different ecological environment, the iron and steel smelting technology in different countries is quite different from that in the middle ages of Europe.

For the sake of cost, the white skin in the middle ages of Europe was poor and only wanted to make wrought iron.

The wrought iron is very neat. Add some quicklime and light a fire in the furnace. The iron oxide will be reduced to iron. The furnace temperature doesn''t need to be too high. It''s not an ordinary way to save fuel.

Moreover, the wrought iron is soft and easy to process (good ductility), and it''s easier to roll out a sharp weapon, the whole body armor.

On the other hand, softness is also the disadvantage of wrought iron. Softness means that it is not wear-resistant at all. If it is made into farm tools such as hoes, all kinds of weeding can be worn out, so the farmers are not happy with it.

If you want to change the wrought iron into pig iron with higher hardness, you have to increase the content of carbon. What should you do?

Add charcoal!

When the carbon content exceeds 2%, pig iron is born.

Pig iron is brittle and hard, super wear-resistant, which is the favorite of farmers.

But the problem is, charcoal costs money.

It takes time.

It takes money and time. The iron can only be made by casting, but it can''t be used as a weapon to make a girl. This time, it''s the masters'' turn not to like it.

MMP, it''s enough to have a look at the whole body armor. It doesn''t need to be rubbed on the ground. It''s hard to make pig iron until you''re full.

Therefore, the old man is to make iron, not pig iron, clay legs love to use, do not roll!

But the world is different.

Exotic trees grow tall and many, but also very resistant to burning, that is, high calorific value, charcoal is easy to obtain, the price is relatively cheap, and high calorific value means less consumption, also can save a lot of money.

Therefore, different from the poor in the middle ages, the people of other countries embarked on a "pig iron road".

With pig iron, the difficulty of steel-making is greatly reduced, that is to remove the excess carbon?

How hard can it be?

In fact, there are many ways, among which the simplest way is even known to fools, that is, one word - knock!

The specific operation process is repeated heating and forging, so that the carbon element will react with the oxygen in the air and become carbon dioxide.

That is to say, after each round of hot forging, the carbon element in pig iron will be reduced a little.

When the carbon element is low to a certain extent, steel appears.

woodlouse is using this "idiot steelmaking method", there is no way, the people of other countries are strong, powerful, able to knock, can be hit, that is, the output of iron and steel is lower.

Originally, this is not a big problem. Over the years, people have made do with it?

Unfortunately, the black orcs broke the rules. They made a breakthrough in steelmaking technology.

Although Renault has not seen the black Orc''s steel-making method with his own eyes, he knows that it is just one of the methods of frying steel and pouring steel.

Stir frying method is to melt the pig iron and keep stirring to oxidize the carbon element. This kind of steel-making method has large output and good quality.

As for the steel pouring method, it is to mix pig iron and wrought iron for smelting. One has a higher carbon content than steel, and the other has a lower carbon content than steel. The final product is just steel. The output of this method is greater.

These two methods are only a matter of thinking, not technical problems. On earth, the ancestors of China invented these two methods more than 1000 years ago.Only the white skinned fools of the middle ages, until the 17th century, understood that steel could be made in this way.

But in the alien world, there is a third kind of steelmaking method, that is, the "magic power steelmaking method" with alien characteristics.

This method didn''t exist a week ago.

In the past few days, Odin has been frequent to and fro Tiejia Island, and can transport nearly 1000 tons of black iron ore every day. After getting enough raw materials, Renault officially started the first "magic power steelmaking" in the alien world.

Whether it is the earth or the alien world, the conventional steelmaking process is divided into two steps, the first step is ironmaking, the second step is steelmaking.

But when Renault thought about the existence of magic energy, which is very unscientific and easy to use, he couldn''t help wondering whether magic energy can be used for steelmaking?

If according to the traditional method, it is both blast furnace ironmaking and converter steelmaking, we still have to find a way to prepare oxygen (the converter needs oxygen), which is very troublesome.

Can we get there in one step?

Can iron ore be thrown into the furnace and molten steel can be produced directly?

After discussing with a group of siege lions from the rune Institute, Renault was surprised to find that Really.

The next magic black technology to appear is called Rune decomposition.

As the name suggests, it can directly decompose compounds into elemental elements.

For example, mud, that is, silicon dioxide, if you throw it into a container engraved with runes, only pure silicon will be left in the container.

Wait, what about the decomposition? Where''s the oxygen?

Is that a question? It turns into gas and flies away.

Of course, you can also choose to make the container completely sealed, but it''s unnecessary. There is oxygen everywhere in the air. There''s no charge for a large amount of tube full. What''s the use of trying to collect this oxygen?

The effect of [decomposition] is so powerful that it has a big future.

In fact, the most original [decomposition] comes from a powerful and extraordinary thing - the sword of annihilation.

It is said that after being cut by the annihilation sword, the part where the blade touches will turn into black and gray instantly. No matter ordinary people or powerful and extraordinary people are hit, it will be the same result.

This is easy to understand, because the main component of human tissue is a pile of carbon, hydrogen and oxygen compounds. After they are decomposed, colorless and tasteless hydrogen and oxygen disappear into the air, leaving only black carbon element visible to the naked eye.

Therefore, in the end, it seems to be the pulling effect of "a sword goes up in smoke".

Even if the enemy is armed with defense equipment such as metal shield, it can''t stop the annihilation sword. As long as the sword is waved, the shield will split into two in an instant, and the metal touched by the blade will turn into iron slag in seconds.

To some extent, the sword of annihilation can be called invincible.

Unfortunately, just a few seconds after Renault was fascinated by it, Seth told him that the sword of annihilation had disappeared a long time ago.

However, the great power of a rune magician, that is, the inventor of the rune, Mr. Tianqiong Dalao, was lucky enough to have contact with the annihilation sword, and he also successfully studied the early generation of decomposition from this extraordinary thing.

Later, with the improvement of generations of Rune magicians, compared with the original version, the structure of decomposition has changed a lot, and the efficiency has also improved a lot.

Of course, the specific effect of [decomposition] is far less than that of annihilation sword, but the effect is the same, but it can only work on non magic matter. Once it encounters magic matter, it will completely fail due to the existence of magic interference.

Although it looks fantastic, Renault can understand the logic behind it.

From a chemical point of view, [decomposition] can smash all chemical bonds, whether ionic bonds, covalent bonds or metal bonds, with the help of magic energy. It can directly erase them and reduce compound molecules to atoms or single element molecular states.

In addition, decomposition has a fatal disadvantage, that is, it must be driven by magic crystal.
