Live Wilderness Adventure

The seventeenth day of survival in the Banna Rainforest.

After beating by the stove for a full day, the original iron ball has been completely stretched and developed into a long strip. For this reason, Bi Fang smashed two stone hammers.

Choosing to smelt into steel is a race against time. Since yesterday, Bi Fang has been working every day until late at night, getting up before dawn to warm the furnace and melt iron.

The daily sleep time is less than six hours, which is probably a boon for audiences around the world, because they no longer have to worry about the jet lag of live broadcasts, as long as they turn on their mobile phones, they can almost see either hammering iron or hunting. .

The eighteenth day of rainforest survival.

Perhaps it can no longer be called survival. Since the day Bi Fang decided to make iron, it has left the scope of survival and has become life.

It was still dark, and Bi Fang, like a blacksmith, skillfully got up and washed, and finally turned on the furnace.

Far and away kept throwing in the charcoal fire, so Bi Fang made at least one pit charcoal every day.

The high temperature in the furnace blackened his whole body, and Bi Fang, who was sweating like rain, clamped the red and dazzling iron bars and kept beating them.

At noon, the long iron bar was slammed and bent and folded again.

It was the first time he had folded and forged, and Bi Fang couldn't remember it himself, but only vaguely remembered a number. He felt that his arm was about to break.

Continue to put the iron bar into the furnace to heat.

After drinking a few sips of water to rehydrate, Bi Fang stepped aside and washed his face, revealing his wheatish complexion, gasping for breath. .

"How do you say that, laziness is the root of productivity development. Although it's a joke, I think it really makes sense."

During the break, Bi Fang would choose to chat to retain the audience in the live broadcast room.

The science is very popular, but a considerable number of people are willing to stay and listen.

After all, **** Bi Fang, online popular science, is still quite attractive.

The desire for knowledge is also the desire.

"We use charcoal as fuel, smelt iron ore into solid sponge-like blocks in the furnace, and take it out after the furnace cools, which is actually called block iron smelting. This is what we did about 2,500 years ago."

"Block iron smelting has low carbon content, soft texture and many impurities. It is wrought iron obtained by human beings in the early days. Using block iron smelting as raw material, heating it in a carbon fire to absorb carbon to increase the carbon content, and then forging to remove it. The magazine is infiltrated with carbon, which gives steel."

"This kind of steel is called block iron-making carburizing steel. However, the quality of this kind of steel is not good enough. It is very difficult to grasp how much carbon is infiltrated during the refining process, whether it is evenly distributed, and how much impurities are removed. Production efficiency is extremely low.”

This steel is of course substandard, no matter what tool it is used for.

"In order to improve the quality of steel, craftsmen in the middle of the Western Han Dynasty invented 'Hundred Steelmaking'. This is what we are doing now, by repeatedly heating, folding and forging the block iron to make the steel dense in structure, uniform in composition, and reduced in impurities, thereby improving the quality of steel."

This is what Bi Fang has been doing now, constantly forging and forging the resulting blocks of iron.

At this time, iron is both raw and cooked, or it can be said that it is not raw or cooked.

Bi Fang called it the duality of raw and wrought iron!

"Haha, just kidding." Bi Fang scratched his head.

"The demand for steelmaking is increasing, but the production efficiency of its raw material block ironmaking is very low, and it must be 'cooled' to obtain it after smelting, so the development of steelmaking has been limited.

The most important thing is that it is too tiring. A piece of iron needs to be forged for at least a hundred times before it can be considered a shape, so it is called a hundred training. However, the nutrition of the people at that time could not keep up, and when weapons were needed to fight, It is possible for craftsmen to die from exhaustion. "

"In order to break through this limitation, the craftsmen have invented a new pig iron steelmaking technology, fried steel. I also mentioned it a few days ago. This is a hang."

"Frying steel heats pig iron to a liquid or semi-liquid state, stirs it in a furnace, uses blasting or sprinkles concentrate powder, etc., and uses oxygen in the air to oxidize silicon, manganese, and carbon, and reduce the carbon content. So steel is obtained. Stir-fried steel gets its name from the constant stirring during the smelting process, just like cooking vegetables.”

China started frying steel more than 1,600 years earlier than the technology of frying steel started in the UK in Europe.

After chatting with the audience for a while, Bi Fang poured the remaining water on the top of his head, came to the blast furnace, removed the furnace cover, and continued to forge.

Hundreds of refinements, one hundred refinements, how can you do it without a hundred times.

Forget it, Bi Fang has played for nearly three days, and it is not enough for fifty-five times, which is far from enough. This is still the result of the softer texture in the early stage. The later stage, the more difficult it is to forge.

There are only more than three days left, and we have to work harder.

"Grandma, it's no wonder that the craftsman is exhausted. I'm almost exhausted."

The nineteenth day of Banna.

Today, Bi Fang worked hard, forging for more than 13 hours, folded 21 times, and the total number of times came to 76 times.

At this time, the iron was far less soft than it was at the beginning, it became harder and harder to beat, so Bi Fang had to find a better stone hammer, and the surface layer had to be glued with a layer of tree board to prevent the toughness from being too low and breaking. .

this is a good news.

It shows that the quality of iron in Bi Fang's hands has become higher, and he has begun to develop towards steel.

It is worth mentioning that the water monitor lizard ran to the stove at night and was hit by a piece of red charcoal, causing a black scar.

Since then it has never dared to approach the blast furnace.

The 20th day of survival in the Banna Rainforest.

In a whole day's work, Bi Fang only folded the steel bar fifteen times, and the total number of times reached ninety-one times.

At night, Bi Fang was lying on the bed, his right arm was sore and unbearable, and he had to soak it all in cold water.

These days, millions of viewers accompany Bi Fang in the live broadcast room, watching the iron initially bigger than a fist turn into an iron bar, bending and folding again and again.

The volume is getting smaller and smaller. So far, the iron bar has been smaller than the initial circle. If it is hammered and polished, everyone believes that it is already a good dagger.

[Either forget it, it feels too difficult]

【Is it almost iron? 】

Gu Su

[This makes me hammer for a day, no, half a day, I'm going to die]

[Lao Fang is really a man, I feel like I'm steel now. 】

[I wouldn't watch the Broken Knife Contest without you]

Bi Fang smiled and smiled happily

"If the iron in my hand hadn't become harder and harder, I might have really given up, indicating that there are a lot of other impurities in it, and the possibility of connecting into steel is very low, but it doesn't, so I must do it to the best."

Iron is made into steel after a thousand trials and tribulations!

Without countless blows and exercises, the processing performance and use performance are all scumbags!

This is not only steel-making, but also self-training. Only when it is done to the extreme and can no longer be folded can it be the answer sheet that Bi Fang handed over.

The perfect answer in his heart.

Thinking of this, Bi Fang abruptly got up from the bed, water droplets flowed down his slightly swollen arm, vines wrapped around his palm again, stretched out his hand to hold an unknown stone hammer, and returned to the outdoors.

I will leave here in six days tomorrow night. I must complete the forging before tonight, and I will have enough time to polish it tomorrow.

Open the furnace, make iron!

The twenty-first and last day of Banna Rainforest Survival.

At this time, it was still dark and the audience didn't sleep. They stayed up all night with Bi Fang, watching the red iron bars folded again and again in the dark, exploding sparks, and falling off the black iron sheets.

In the early morning, with the final blow of the sledgehammer, the stone shattered and spalled again and fell to the ground.

Bi Fang was staring at Venus and didn't sleep all night, which made his exhaustion value at the peak at this moment. He had no doubt that if he was given a soft bed at this moment, he could fall asleep on his back.

"How many times is this?"

[101! 101 times Fang Shen! 】

[Hundreds of steelmaking, really a hundred steelmaking]

【Have you started grinding yet? 】

Bi Fang shook his head, continued to heat the iron bar, turned around and entered the room and took out another stone hammer.

He said that he had to hammer until he could not move the unknown.

In the early morning, the sun slanted across the trees and shone on Bi Fang.

He has not applied anti-mosquito mud for several days. The high temperature here makes even mosquitoes reluctant to approach.

The water monitor lizard flicked its tail and climbed out of the cave. The IQ of the cold-blooded animal is not enough for it to think about too many complicated problems. However, it was still deeply shocked by not sleeping all night.

This creature is terrifying.

A full five days.

Bi Fang's complexion has changed, turning into a healthy wheat color, every hair is glowing with golden light in the early morning sun, and sweat is gurgling along the gaps in the muscles.

After days of hard work, the salt in Bi Fang's body quickly disappeared. If it weren't for the salt, animal blood alone would not be able to get enough of it.

The sound of the collision of gold and iron sounded, and Mars sputtered again.

One hundred and two.

Continue heating.

One hundred and three times.

Bi Fang ate breakfast. In order to save time, even the fish only ate large fish without spines, or the belly of fish with spines, and the rest was given to the water monitor lizard.

Perhaps this wild water monitor lizard never thought in his life that he could eat cooked food by himself.

The giant hammer fell again, and a huge rebound was transmitted to the arm, and Bi Fang suddenly let go.

In the forest, Qingyue's metal trembling continued for a long time.

This time, the orange steel bars on the slate did not react at all.

Bi Fang suddenly fell to the ground, and his eyes were blackened one after another, and cold sweat poured out layer after layer.

It's not easy, UU reading www. uukanshu.com is really not easy.

Everything in front of me is not so real.

It took more than five days of tempering time, more than twelve hours of beating every day, and less than six hours of sleep time. Finally, a qualified steel rod was hammered!

【This is...steel? 】

Looking at the red iron bar that stood up on the stone plate, no, it should be called a steel bar now, and everyone just felt a sense of magic.

【Am I really on earth? 】

[So, Fang Shen really made a piece of...steel in the wilderness? 】

In the first venue, the audience stuttered and looked at each other, as if to verify what they had seen.

But the shocked expressions on everyone's faces told them.

That's right.

This is.

steel!
