As we all know, the main difference between pig iron (cast iron), wrought iron, and steel is around the carbon element. Pig iron has the highest carbon content, followed by steel, and wrought iron has the lowest.

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

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

As a mechanical dog, the above is all familiar knowledge. As a crossing dog in a mechanical dog, this is the basic skill in the basic skills, which belongs to the knowledge that must be mastered and applied skillfully.

If the steel can't be made, then grow a field of wool? It's better to wipe your neck as soon as possible and see if there is a chance to wear it back again.

Please note that this is definitely not a humiliation, but a sincere suggestion.

Because according to the law of crossing the alien world (farming stream), most people who traverse will face many obstacles, and even the unlucky ones who will kill themselves when they first arrive, there are also many people.

There are only a handful of travellers who can eat and wait to die, and you may not be able to find one after reading a hundred books.

What should I do?

Self-improvement!

Steelmaking and ironmaking are the first step to self-improvement and the first cry from the farming party members.

Only by smelting steel and iron can you have a chance to keep your underpants so that you won’t lose horribly; if you want to mix better, you must smelt good steel and iron, so that it is possible to blow the enemy’s ribs and penetrate them. The skull of the enemy.

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

To die by suicide is to avoid the pain and humiliation of being violently beaten by the enemy, and secondly, there is a chance to fight back.

Due to the different ecological environment, the steel smelting technology in other worlds is very different from the European Middle Ages on earth.

Out of cost considerations, the white skins in the Middle Ages in Europe were so poor that they were only willing to make wrought iron.

The wrought iron is so neat, add some quicklime, put it in the stove and light a fire, the iron oxide is reduced to iron, and the furnace temperature does not need to be too high, which is not a general fuel saving.

Moreover, the wrought iron is soft and easy to process (good ductility), and it is also easier to pull out a powerful weapon-full body armor.

On the other hand, softness is also a shortcoming of wrought iron. Softness means that it is not wear-resistant at all. If it is made into a farm tool such as a hoe, a special weed can be worn out, and farmers are naturally very unhappy.

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

Add charcoal!

Charcoal and wrought iron are mixed together, piled in a blast furnace and burnt vigorously to allow carbon to penetrate into the wrought iron. When the carbon content exceeds 2%, pig iron is born.

The texture of pig iron is brittle and hard, and it is super wear-resistant.

But the problem is, charcoal requires money.

It takes time to burn.

It takes money and time. The iron nuggets can only be cast, and they can't be used to create a sharp weapon for girls. This time it's the master's turn to be unhappy.

MMP, the whole body armor is enough to have a look, and there is no need to rub it on the ground. You can only make pig iron when you are full.

Therefore, the masters just want wrought iron instead of pig iron, and mud legs love to use it, don't need to roll!

But the other world is different.

The trees in other worlds grow taller and more resistant to burning, that is, they have high calorific value, charcoal is easy to obtain, and the price is relatively cheap, and the high calorific value means that the amount can be less, and it can also save a lot of money.

Therefore, unlike the poor in the Middle Ages, people from other worlds have embarked on a "road of pig iron."

With pig iron, the difficulty of obtaining steelmaking is greatly reduced, isn't it just removing excess carbon?

How hard can it be?

There are actually many ways. The easiest way is one that even fools know, just one word—knock!

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

In other words, after each round of heating and forging, the carbon element in the pig iron will be reduced a little.

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

It is this kind of "stupid steelmaking method" used by the alien turtles. There is no way. The alien people grow strong, strong, able to beat and beat, which means that the output of steel is a little lower.

This is not a big problem at first, hasn't everyone made do with it like this for so many years?

It is a pity that the Black Orcs fouled, and they made a breakthrough in steelmaking technology.

Although Renault hadn't seen the black orc steelmaking method with his own eyes, he knew it with his butt, it was nothing more than one of the frying steel method and the steel filling method.

The frying method is to melt the pig iron and stir it continuously to oxidize the carbon element. This steelmaking method has a large output and good quality.

As for the steel filling method, pig iron and wrought iron are mixed and smelted. One has higher carbon content than steel and the other lower than steel. The final result is just steel. This method has a larger output.

These two methods are just a question of thinking, and there are no technical problems. On the earth, the ancestors of the Chinese nation invented these two methods more than a thousand years ago.

Only the white-skinned fools of the Middle Ages didn't understand until the 17th century that steel could be made in this way.

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

This method did not exist a week ago.

In the past few days, the Odin frequently travels to and from Iron Armor Island, and can transport back nearly 1,000 tons of black iron ore every day. After obtaining enough raw materials, Renault has officially started the first "magic steelmaking" in another world.

Whether it's the earth or another world, the conventional steelmaking method is divided into two steps, the first step is ironmaking, and the second step is steelmaking.

But when Renault thought about the existence of magical energy in the alien world, which is very unscientific and extremely useful energy, he couldn't help but wonder whether magical energy could be used to make steel?

If you follow the traditional method, blast furnace ironmaking, and converter steelmaking, you have to find a way to produce oxygen (the converter needs oxygen), which is terribly troublesome.

Can it be done directly in one step?

Can I throw the iron ore into the furnace and tap the molten steel directly?

After discussing with a group of siege lions from the Rune Research Institute, Renault was surprised to find that it seemed...really possible.

The magic black technology that will appear next is called Rune [Decomposition].

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

For example, mud, which is silica, if you throw it into a container with runes, only pure silicon will remain in the container.

Wait, what about the good decomposition? Where is the oxygen element?

Does this still need to be asked? It turned into gas and flew away.

Of course, you can also choose to make the container completely sealed, but this is unnecessary. There is oxygen everywhere in the air. There is no charge if you are full of large tubes. What is the use of trying to collect this oxygen?

The effect of [Decomposition] is so awesome, and its background is not small.

In fact, the initial [decomposition] came from an amazingly powerful and extraordinary thing-the sword of annihilation.

It is said that after being slashed by the Sword of Annihilation, the part that the blade touches will instantly turn into black and gray, whether it is an ordinary person or a powerful transcendent, as long as it is hit, the result will be the same.

This is easy to understand, because the main component of human tissue is a pile of carbon hydroxide. After they are decomposed, the colorless, odorless hydrogen and oxygen disappear in the air, and only the black carbon element can be seen by the naked eye. .

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

Even if the enemy is holding defensive equipment such as a metal shield, it can't stop the sword of annihilation. As long as a sword is swung away, the shield instantly splits into two, and the metal touched by the blade becomes iron **** in seconds.

To some extent, the Sword of Annihilation can be said to be invincible.

Unfortunately, Renault had just been fascinated for a few seconds, and Seth told him that the sword of annihilation had been missing a long time ago.

However, the great power of a rune magician, that is, Mr. Sky Dalao, who invented the rune [Sky], had the honor to have access to the sword of annihilation, and successfully recovered from this extraordinary thing , Researched out the first generation [decomposition].

Later, through the improvement of generations of rune magicians, compared with the original version, the structure of the now handed down [Decomposition] has undergone a lot of changes, and the efficiency has also improved a lot.

Of course, the specific effect of [Decomposition] is definitely far less than that of the Sword of Annihilation, but the effect is the same, but it can only work on non-magic matter. Once it encounters magical matter, due to the interference of magical energy, It will completely fail.

Although this thing looks very fantastic, Renault can still understand the logic behind it.

From a chemical point of view, [Decomposition] can use the power of magic energy to crush all chemical bonds, whether it is ionic, covalent or metal bonds, it can directly erase them, reducing compound molecules into atoms, or Single element molecular state.

In addition, [Decomposition] has a fatal disadvantage, that is, it must be driven by mana spar.
