"The furnace temperature is 1000 degrees..."

"The heat recovery device is transmitting heat magic energy to the heat magic steelmaking furnace..."

There was another big cheer, even the LORD was smiling.

Although I don''t understand what this means, McGregor also saw that it is obviously a very bad thing.

"Furnace temperature 1500 degrees..."

"The furnace temperature is 2000 degrees..."

"The thermal magic energy on the heat recovery device has reached 60% of the design peak value..."

After hearing this, McGregor suddenly remembered something. He heard a civil servant in the Department of industry say that the melting point of steel is more than 1500 degrees, and that of iron ore is lower, generally only about 1200 degrees.

In other words, even if it is necessary to cast pig iron ingots, 1600 degrees at most is enough.

Why heat it to 2000 degrees?

When he was full of doubts, pierce beside him asked in a low voice: "with such a high temperature, the iron ore must have melted into molten iron. The Lord and the consul are standing so close. Don''t they feel hot?"

McGregor also found something wrong. Usually, when they use blast furnace to make iron, the heat wave around the blast furnace is rolling. They can''t hold people within 5 meters, and they only feel hot within 10 meters.

But look at the Lord and the consul, there is no sweat on the skin, it seems that there is no feeling of heat.

Lord, you are a powerful and extraordinary person. You may not be afraid of the heat, but I haven''t heard that the consul lady is also an extraordinary person.

It''s not only the two great figures, but also the ordinary civil servants around. The black uniforms are almost pasted on the surface of the steel-making furnace. It seems that the furnace is not filled with ultra-high temperature molten iron, but with warm water.

But McGregor believes that no one dares to deceive the Lord face to face. Since the black uniforms shout "2000 degrees", the temperature must be so high.

This kind of unusual anomaly makes McGregor feel that his three outlooks have been completely overturned.

He has lived for more than 30 years. He has never heard of this incredible steelmaking method.

"Furnace temperature 2500 degrees..."

"The thermal magic energy on the heat recovery device has risen to 80%..."

At this time, a huge cry appeared, and a tremor could be heard in the voice.

"Start [decomposition] of Rune group now!"

A black uniform seems to have been ready for a long time. At the moment of hearing this command, he immediately gave a loud response and quickly put his right hand on a rune square on the surface of the hot magic steel furnace.

Just like when the heater was activated, blue light began to flash on this Rune square board. The only difference was that the lighting speed was relatively slow. It took four or five seconds for the square board to be completely covered by blue light.

It also means that the rune is fully activated.

At this time, however, McGregor saw a strange scene.

The metal tube at the top of the steelmaking furnace began to tremble slightly, and he heard a slight "hiss".

This is The sound of the air!

Even the metal tube was trembling, which indicated that the jet was quite violent.

More than ten seconds later, the shaking of the metal tube became more and more obvious, and the sharp whistling of the air became more and more loud. It was like a storm outside the workshop.

Along with it, too, was the confusion in McGregor''s mind.

What kind of steelmaking method is this?

Why are you still blowing gas?

Where is the impurity in iron ore, namely slag?

Don''t you have to think about slag removal?

, however, as like as two peas, Maigret did not dare to speak, nor could he find anyone to ask. Everyone in the man he knew had the same doubts as he did.

He can only wait quietly for the answer to be revealed.

One of the great advantages of magic power steelmaking is that it has no residue.

Under the action of the [decomposition] of the rune formation, all the components in the iron ore will be completely decomposed into elemental matter. For example, the main component, ferric oxide, will be directly decomposed into iron and oxygen, which is the reason for the gas flow.

It''s easy to understand why the air flow is so violent.

For each unit of Fe3O4 decomposed, three parts of iron and two parts of oxygen will be produced.

The volume of one mole of oxygen is 22.4 liters, while that of one mole of hot metal is only 7.2 ml. the volume difference between the two is several thousand times. In other words, in the process of ironmaking, the volume of oxygen produced will be 2000 times that of hot metal.

So much oxygen, of course, there will be a gas blowout phenomenon.

In addition, iron ore also contains other impurities, such as phosphorus, sulfur, potassium, sodium, arsenic and other harmful elements, as well as manganese, nickel, chromium, vanadium, titanium and other beneficial elements.

Phosphorus, in particular, can lead to a serious decline in the quality of steel, that is, the so-called "cold brittleness", while sulfur can lead to "hot brittleness".In the normal steelmaking process, if the phosphorus and sulfur content of iron ore is large, special phosphorus and sulfur removal process must be adopted, which also means that additional fuel cost is needed, and eventually the total cost will rise.

But with the help of the decomposition of the rune group, there is no need to worry about the above.

At a high temperature of more than 2000 degrees, the decomposed phosphorus, sulfur, potassium, sodium and arsenic will all become gaseous. With the oxygen discharged from the magic energy steelmaking furnace, there is no residue.

That''s right. The magic power steelmaking method is so awesome!

This step has a special name: Mana decomposition.

In the process of waiting for nearly three minutes, no one spoke, even those black uniforms. The wide workshop fell into silence, only the sharp sound of the sharp air flow came continuously.

And the whistling is getting smaller and smaller, which shows that the gas emitted from the magic energy steelmaking furnace is less and less.

After another two minutes, when the workshop can only hear heavy breathing sound, a voice suddenly broke the silence.

"Close Rune Group [decomposition], add charcoal..."

"Open Rune Group [smelting], ready to stir..."

Several black uniforms moved quickly. Everyone put their right hands on the surface of the steel-making furnace, and the blue light flashed again.

McGregor noticed that there was more than one Rune square plate on the surface of the steel-making furnace, but there were as many as five or six.

It can also be seen from this that the internal structure of the steelmaking furnace must be quite complicated.

The workshop is quiet again. You can hear a slight vibration from the steel-making furnace. It seems that something is spinning inside.

This time, the waiting time was a little longer. About five minutes later, the black uniform in charge of the command spoke again.

"Release the molten steel!"

"Cool the billet!"

"Ready to turn on the conveyor belt!"

Mcgraton was dumbfounded when he was in the middle of the night.

This is The billet has been tapped

Is there any mistake?

Am I crazy or are these black uniforms crazy?

How could it be so fast?

Doesn''t it take three or four hours to make iron in blast furnace?

The steel-making time is not so short. The masters of the industry department have made a steel pouring method. It takes at least four hours, doesn''t it?

But how long has it been?

Less than half an hour!

Not only McGregor, but also the people who know a little about steelmaking and ironmaking in the territory are concentrated here. Without exception, these people are all tongue tied.

There was also a slight commotion in the crowd. If it wasn''t for the presence of the Lord, I''m afraid someone could not help whispering.

The action of the black uniform is very sharp. The three black uniforms each hold a silver white iron box and go to the left exit of the steelmaking furnace.

These iron boxes are not big. They are not more than 40 cm in length and width, but shorter in height. They are less than 20 cm in height. The materials seem to be very thin. The black uniforms are very easy to hold.

Strangely, the surface of the metal box was still faintly blue. It was the first time McGregor saw this color of steel, which made him look more curiously.

In addition, the inside of the box seems to be coated with a layer of grease, which looks very bright.

A black uniform quickly put the iron box into the furnace, and then there was a "click" sound in the furnace.

However, the sound sounds intermittent. After a few seconds, it stops. After more than ten seconds, the sound of "click" starts again.

At this time, the steps at the right exit of the steel-making furnace began to rotate slowly. McGregor looked at it and realized that it was mostly the conveyor belt of the black uniform.

The conveyor belt had just moved less than 2 meters when a silver box suddenly came out of the exit.

It''s the metal box that the black uniform put in just now!

However, unlike before, there was a silver metal block in the box.

"The ingot came out..."

A black uniform called out cheerfully.

Boom!

This sentence immediately ignited the atmosphere in the workshop. The black uniforms cheered again. The Lord and the consul lady also stepped forward and stood by the conveyor belt and looked around.

McGregor''s chin fell to the ground and his eyes bulged.

Under normal circumstances, shouldn''t it be molten steel?

After just a few seconds, the ingot cooled down?

Is this a fake?

The ingot inside is not the wood painted silver white, is it?

But McGregor''s suspicions were soon falsified.

In the incredible eyes of a group of people, a strong man in the uniform of an island guard stepped forward to turn up the metal box. The ingot suddenly fell out of the box and fell on the concrete floor, making a very dull sound.

Bang!This is the sound of metal ingot.

This sound, just like hitting McGregor''s heart, he clearly felt that there was a "click" in his brain.

His three outlooks are broken!

Not only McGregor, the moment the ingot appeared, his chin fell off the concrete floor in the workshop.
