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

Previously.

for nearly two thousand years.

The technology of making Uzi steel.

Always a closely guarded secret by Indo metallurgists!

The ancient Indus have monopolized the production and export of this metal from beginning to end!

as early as 500 BC.

Uzi steel began to be exported to all over the world.

in that era.

No steel produced by Ouzhou can match the quality of Uzi Steel!

so.

the next few centuries.

Indo is still the leader in Uzi steel production.

until the Middle Ages.

The Frankish expedition was frustrated.

I just started trying to research the production method of this deadly metal!

but.

In the end, they didn't even see the true meaning of it!

then.

Many metallurgical experts in Ouzhou have learned through research.

The ratio of carbon-rich materials may be the key to refining Uzi steel!

Also "eight zero three" is to say.

To make Uzi steel, how much "carbon" needs to be added to the steel?

This question seems simple.

But it has stumped countless Ouzhou craftsmen!

because of this ratio.

It's so hard to master!

If it is out of control.

"Carbon" doesn't just make iron stronger.

Instead, it will become the soft underbelly of steel.

High carbon does give steel a sharp edge and good retention!

But the amount of carbon in the whole mixture.

almost uncontrollable.

This is also the secret of Uzi Steel!

Carbon content is too low.

will become mature iron.

Wrought iron is too soft to be used in weapon making.

Carbon content is too high.

It will become cast iron again.

Cast iron is too brittle.

Still not.

also.

If the machining process is wrong.

Steel can even become a large discus of iron carbide.

This is an unbearably brittle iron.

in the age of the Crusades.

For the needs of the war, Ou Zhou's sword craftsmen have tried their best to compete with Arab's counterparts in talent competition!

They tried different processing techniques.

The steel and iron are made by folding process.

Or treat steel with silver and acid!

Attempts to imitate the unique corrugated structure of Damascus steel.

But it's a pity.

Neither succeeded!

until now.

The hidden secret of Uzigang.

Still no truth out!

later.

Due to historical changes and the development of the times.

In addition, the Uzi hematite mine in Indu was exhausted at the end of the 17th century.

This unique cast pattern steel naturally disappeared.

The making of Damascus steel knives is lost!

With the decline of cold weapons.

Disappeared together in the long river of history!

Now even the local metallurgical craftsmen of Indu.

The legendary metal that frightened the Frankish knights could not be made!

In today's society.

There have been attempts to use modern science to analyze and replicate the Damascus steel knife, but all have failed.

Today's Damascus has become synonymous with patterned steel!

Modern Damascus steel is just welded type patterned steel!

This pattern is made for aesthetics only.

doesn't make any real sense.

It can even be said that it is useless!

It is no longer the pure hand-playing style of the past!

If not for the production technology provided by the system.

Jiang Kui can't guarantee that he can make this mysterious metal that has been lost!

Even if he has obtained rare hematite!

The hidden secret of Uzigang.

In fact, it lies in the control of carbon content in steel!

And the rhythm and details of the subsequent low temperature forging!

Both are indispensable!

This kind of forging is similar to the traditional Chinese "cold forging"!

But different!

Uzi steel has strict temperature requirements from smelting to forging!

The temperature during smelting shall not be higher than 1,000 degrees.

Forging must be low temperature!

usually.

Steel has better plasticity at high temperature!

When ordinary craftsmen make swords, they will be beaten and formed at high temperature.

But if Uzi steel is used for high temperature forging.

There will be a lot of carbon loss in it!

Carbon crystals are also destroyed.

Therefore, the temperature during forging should not be too high!

Various details.

Hard to master!

The required skills, experience, and much more than other steels!

And these.

That's what makes it so precious!

The live stream continues!

The iron sand has been screened!

Jiang Kui brought the biggest clay cauldron in the camp!

then.

Pour iron sand into it!

Immediately after.

According to the ratio given by the system, he added a certain amount of grass ash and fresh hibiscus leaves to the iron sand as carbon-rich materials!

Back then, when metallurgical experts in Indu made Uzi steel, the rich materials used were also some plant leaves and charcoal.

Spread the carbon-rich material on top!

at last.

Jiang Kui takes the clay again.

Seal the crucible!

Why do it.

The purpose is to make the temperature more constant!

And this detail.

Also different from other open crucible metallurgy!

See here all the way.

The audience in the live broadcast room drew a big question mark in their hearts!

I have absolutely no idea what this is doing!

The process of refining metal is something that everyone knows a little bit about.

But the practice of adding charcoal and leaves to the crucible is the first time they have seen each other!

【I go, what is this operation?】

【Looking dumbfounded!】

【Mumbling! What high tech is Master Kui doing?!】

【Add mysterious seasoning? If you don’t understand, ask, is this stuff delicious?】

【Ha ha!】

【Iron filings + leaves =? What kind of weird combination is this?】

【Amazing my brother!】

at the same time.

Inside the global studio!

When seeing this scene.

Physicist Philip Ron, also frowned!

The expression on his face is extremely complicated!

Seems to be thinking of something.

But not sure yet!

"Professor Philip, what do you think of this?"

Hear the host ask questions.

Philip remained silent.

Thinking to himself.

After a while, he said leisurely:

"Charcoal and leaves become 5.7 carbon-rich materials when burned.

"He seems to be trying to turn these iron filings into carbon steel?"

In a word.

Suddenly, thousands of waves were stirred in the live broadcast room!

The barrage is endless!

【What? Steelmaking?】

[Carbon steel? Woo grass! It looks like this is the case! 】

[No way, the production of iron-carbon alloys is not so simple, right?]

【Yes! Do you need to add other materials to carbon steel?】

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%.

The production process is not very complicated!

But it can't be made by adding a few leaves and charcoal ash!

"Indeed it is……"

Looking at the big screen of the live broadcast, Philip continued to ponder:

"This is also what puzzles me, so I think things are not as simple as we think

(One more, ask for votes!).
