Fake Extinction of All Mankind, and I Rebuild Civilization with my Bare Hands was Broadcast Live

Due to the addition of carbon-rich materials.

Pure iron will be in the refining process.

Gradually transformed into a binary alloy!

This binary alloy.

It is the iron-carbon alloy that people often say.

Commonly known as carbon steel.

Carbon steel is made from pig iron.

It is a very common metal material.

Have high mechanical strength and toughness!

It also has special properties such as heat resistance, corrosion resistance and wear resistance.

The tensile strength, plasticity and toughness of ordinary cast iron are lower than those of carbon steel.

Uzi steel is also a kind of carbon steel!

The difference between Uzi steel and ordinary carbon steel.

It only depends on the amount of carbon.

besides.

The two are no different.

but.

usually.

The production of carbon steel is rich in carbon.

Many other metal elements also need to be added to ensure the hardness and retention of engineering steel.

Multi-purpose open-hearth refining.

Primitive steelmaking methods like Jiang Kui.

Forget the audience.

Even Philip was seeing it for the first time!

The principles of the two are the same.

Can only these materials be used to make iron-carbon alloys in modern industry?

Philip dared not jump to conclusions.

Can only wait and see!

soon.

everything's ready.

Jiang Kui sealed the earth and opened the kiln again.

and pre-sealed crucibles.

Put it on the grate.

While pulling up the blower meticulously.

While watching the changes in the charcoal fire all the time.

to ensure temperature concentration.

Avoid accidents such as frying.

"Hoohoo-hoo-!

a time.

There's a lot of wind in the camp!

Follow the rhythm of the fan blades.

Spread all over the world.

Soon.

Charcoal fire in a kiln.

The more it burns, the more red it becomes.

Less than an hour before and after.

The sealed crucible that was wrapped had a very obvious reaction.

The ears are close to the furnace wall.

You can clearly hear the sound of sizzling!

see.

Jiang Kui didn't stop there.

On the contrary, it got even worse!

until the sound stops.

The blowing stopped when the inside and outside of the crucible turned red!

at this time.

Look inward through the kiln mouth.

The crucible and the charcoal are completely integrated!

but.

It's not over yet.

The whole refining process will take a long time.

Warm up first.

Cool down again!

Warm up again.

Cool down again!

It takes at least 20 hours of refining.

To get a perfect ingot!

During this period.

The temperature in the kiln needs to be repeatedly jumped from one thousand degrees Celsius to one thousand two hundred degrees Celsius.

Until the iron and carbon in the crucible are fully fused!

Follow this process.

Such and such.

over and over again.

Busy all night.

The refining process enters the cooling and decarbonization stage!

Take the opportunity to take a nap.

When it was just dawn.

It rained again on the island.

After getting up from the bed.

Jiang Kui came to the kiln to check it out for the first time!

at this time.

The kiln has cooled down completely.

Crucible on the grate.

It has also been burnt out.

Remove the ashes.

Jiang Kui took the crucible out of it.

Then just pick up the hammer.

Smash it!

boom!

moment.

The crucible was torn apart.

follow closely.

A semi-shape-seeking steel ingot the size of a slap jumped into view at the same time!

Steel ingots are like dark iron.

No sheen.

This original steel ingot.

It was called "God Iron" by the ancient Indians

.

That is the prototype of Uzi steel.

After decarburization of god iron.

You can turn into a real Uzi steel!

Hold the ingot in your hand.

Just by touch.

Jiang Kui is sure.

Not surprisingly.

Should be successful.

thinking.

He hurriedly put the steel ingot on the anvil, picked up the hammer and struck it hard a dozen times!

boom!

boom!

boom!

The sound is crisp and long!

Normally cast Uzi ingots are very hard.

After hammering.

There won't be any dents on the surface either!

Very powerful!

【Wood grass!!!】

【Isn’t this the legendary carbon steel?】

【Flowing beer! It becomes so hard after adding mysterious condiments? 】

【How is steel made! 】

【Invincible! The sound seems to be really steel! 】

[Understood, understood! Leaves + iron = steel! 】

From the appearance point of view, this steel ingot seems to be no different from the iron-based materials used in today's engineering.

Hardness test feedback.

The beating sound is not much different!

But in fact it is not.

after decarbonization.

After repeated beating.

The unique pattern of Damascus steel will appear immediately!

In order to have a glimpse of this kind of lost millennium divine iron style as soon as possible.

Jiang Kui didn't waste time anymore.

Rekindle the fire!

Wrap the ingot with a lot of clay.

Put it in the oven again.

Start heating!

Wait until the temperature reaches 700 to 900 degrees Celsius before taking it out!

This temperature is very critical!

It is simply the top priority of creating patterned steel!

Because the temperature has risen to more than 900 degrees Celsius.

The cementite and austenite crystals in the ingot will be greatly affected!

Limited to 900 degrees!

Every degree the temperature rises!

The carbon melting rate of the ingot.

It will be a point soon!

And then cause the loss of crystal and wave pattern pattern!

on the contrary.

If the temperature is lower than 700 degrees Celsius.

Neither does it.

Because it is less than seven hundred degrees.

Ingots simply don't get adequate exercise.

As such.

The pattern doesn't show up anymore!

before that.

Why is the blacksmith of Ou Zhou still unable to understand the profound meaning of Wuzigang?

Here's why!

In pursuit of hardness.

Ou Zhou blacksmiths often temper the metal at a high temperature of 1,300 degrees Celsius.

This temperature is really too high.

That's why.

until the end of the war.

None of them have mastered the art of tempering Damascus steel!

The ultimate temperature control!

Repeated training!

This is the essence of Damascus steel being smelted!

but.

in that era.

Since there is no professional furnace thermometer.

Even if they know the essence.

It is also extremely difficult to reproduce it in the same way!

Because of the Indian craftsmen.

Control of temperature.

It's all about experience.

this experience.

No 803 has been passed down through generations and repeated practice.

It's hard to master!

But for Jiang Kui.

These problems are no longer a problem!

With the help of systematically instilled knowledge and the heart of craftsmen.

temperature control.

Can't beat him!

soon!

Burned for a while.

When the clay outside the ingot.

When it turns completely dark red!

The temperature is just right!

see.

Jiang Kui clipped it out with a fire stick at the first time.

Put it on the anvil.

Beat repeatedly!

bang bang bang-!

a time.

The rubble collapses!

Sparks flying on the anvil!

with the loss of carbon.

The hardness of the ingot is also decreasing!

but.

Only this time tempering is not enough!

Next.

This heat treatment process also needs to be repeated continuously.

until the metal is too soft enough.

To proceed to the next forging!

Due to the controlled heat treatment and light tempering of the ingot.

Clay covering the surface.

It will quickly decarburize the surface of the ingot!

As such.

Carbon in ingots.

will gradually decrease.

Reduced from 2.2% or higher to 1.8%!

And then achieve the carbon content of pattern steel!

Soon.

After repeated annealing and beating!

It was originally a steel ingot in the state of white cast iron.

The look has changed!

Against the light.

from a specific angle.

You can already clearly see the looming patterns on it...
