Live Wilderness Adventure

Chapter 502 Boss Fang is Really Tall and Hard

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 be smelted into steel is a race against time. Since yesterday, Bi Fang has been working until late at night every day, getting up before dawn to heat the stove and melt the iron.

The daily sleep time is less than six hours, which is probably a boon for audiences all over the world, because they no longer have to worry about the time difference of the live broadcast, as long as they turn on the mobile phone, they can almost see the figures of hammers and irons or hunting .

Rainforest Survival Day 18.

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

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

Continuously input charcoal fire, so Bi Fang smelts at least one cellar of charcoal every day to be enough.

The high temperature in the furnace blackened his whole body, and Bi Fang, who was sweating profusely, clamped the bright red and dazzling iron bar and beat it continuously.

At noon, the long iron bar was bent by a hammer and folded again.

Bi Fang couldn't remember how many times he had folded and forged, but only vaguely remembered a number. He felt that his arm was about to break.

Continue to put the iron bars into the furnace for heating.

After taking a few sips of water to rehydrate, Bi Fang walked aside and washed his face, revealing his wheat-colored complexion, panting heavily.

"How to say that sentence, laziness is the root of productivity development. Although it is 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 quite a few people are willing to stay and listen.

After all, sexy Bi Fang and online science popularization are quite attractive.

The desire to know is also desire.

"We use charcoal as fuel, and smelt iron ore into a spongy solid block in the furnace. After the furnace cools down, it is actually called iron smelting. This is what we did about 2,500 years ago."

"Block iron has low carbon content, soft texture, and many impurities. It is wrought iron cultivated by humans in the early days. Use block iron as raw material, heat it in a carbon fire to absorb carbon, increase the carbon content, and then forge to remove The magazines are then infiltrated with carbon to obtain steel."

"This kind of steel is called block iron-making carburizing steel. But the quality of this kind of steel is not good enough. It is very difficult to control how much carbon penetrates in the refining process, whether it is evenly distributed, and how much impurities are removed. Very low productivity."

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

"In order to improve the quality of steel, craftsmen in the mid-Western Han Dynasty invented 'Hundred Steelmaking'. This is what we do now. A block of ironmaking is repeatedly heated, folded and forged to make the structure of the steel dense, the composition uniform, and the impurities reduced, thereby improving the quality of steel." quality of steel."

Now what Bi Fang is doing continuously is this step, continuously forging the smelted iron.

At this time, the iron is both raw and cooked, or it can be said that it is neither raw nor cooked.

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

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

"The demand for Baisteel 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 Baisteel has been restricted.

The most important thing is that it is too tiring. A craftsman has to forge a piece of iron a hundred times at least before it can be considered a shape, so it is called a hundred refinements. However, people at that time could not keep up with nutrition, and when weapons were needed for war, Craftsmen may die from exhaustion. "

"In order to break through this limitation, craftsmen have invented a new pig iron and steelmaking technology, frying steel, as I mentioned a few days ago, this is a hang-up."

"Fried steel heats pig iron to a liquid or semi-liquid state, stirs it in a furnace, uses air blasts or sprinkles concentrate powder, etc., uses oxygen in the air to oxidize silicon, manganese, and carbon, and reduce the carbon content. Thus steel is obtained. Fried steel is named because it needs to be stirred continuously during the smelting process, just like cooking.”

China started frying steel, more than 1,600 years earlier than European steel frying technology that started in Britain.

Chatting with the audience for a while, Bi Fang poured the remaining water on his head, came to the front of the blast furnace, removed the furnace cover, and continued forging.

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

Forget it, Bi Fang fought for nearly three days, but it was not enough for fifty-five times, which was far from enough. This was the result of the softer texture in the early stage. The later it was, the harder it was to forge.

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

"Grandma, it's no wonder the craftsmen are exhausted. I'm almost exhausted."

The nineteenth day in Banna.

Today, Bi Fang worked hard, forging for more than thirteen hours, folding twenty-one times, and the total number of times came to seventy-six.

At this time, the iron was far less soft than it was at the beginning, and became harder and harder to beat. Bi Fang had to look for a better stone hammer, and glued a layer of tree boards on the surface with rubber to prevent cracking due to low toughness. .

this is a good news.

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

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

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

Banna Rainforest Survival Day 20.

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. Every time he beat it, his muscles felt uncomfortable for a while.

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

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

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

【Or forget it, it feels too difficult】

[Is it almost iron? 】

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

[Old Fang is really a man, counting to do it, I feel like steel now. 】

[Broken Knife Contest without you, I won't watch it]

Bi Fang smiled happily

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

Iron is made into steel after thousands of tempers!

Without countless blows and training, the processing performance and usability are the five slags of war!

This is not only steelmaking, but also self-training. Only when you achieve the ultimate, and you can no longer fold it, is the answer sheet that Bi Fang will hand over.

The perfect answer in his heart.

Thinking of this, Bi Fang suddenly got up from the bed, water droplets flowed down his slightly swollen arms, wrapped vines around his palms again, stretched out his hand to hold an unknown number of stone hammers, and went outside again.

Tomorrow night, I will leave here in six days, and I must completely forge it before tonight, so that I will have enough time to polish it tomorrow.

Open the furnace and make iron!

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

At this time, it was still dark, and the audience was not asleep. They stayed up all night with Bi Fang, watching the red iron bars folded again and again in the dark, sparks burst out, and the black iron sheet fell off.

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

Bi Fang's head was full of gold stars, and he didn't sleep all night, which made his exhaustion value reach the peak at the moment. He had no doubt that if he was given a soft bed at this moment, he would fall asleep if he could.

"How many times is this?"

[101! 101 times Fang Shen! 】

【Hundreds of steelmaking, really a hundred steelmaking】

[Have you started grinding? 】

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

He said that he should hammer until he can't move.

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

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

The water monitor lizard crawled out of the cave with its tail flicking. The IQ of a cold-blooded animal is not enough for it to think about too many complicated issues, but it was still deeply shocked by not sleeping all night.

This creature is too scary.

A full five days.

Bi Fang's complexion has changed, turning into a healthy wheat color, every hair is glowing golden in the morning sun, and sweat is bubbling down the crevices of 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 supplements.

The sound of gold and iron colliding sounded, and sparks sputtered again.

One hundred and two times.

Continue to heat.

One hundred and three times.

Bi Fang ate breakfast. In order to save time, he only ate big fish without spines or the belly of fish with spines, and gave the rest to the monitor lizard.

Perhaps this wild water monitor lizard has never thought in its life that it can still eat cooked food.

The sledgehammer fell again, and a huge rebound was transmitted to the arm, and Bi Fang let go of it abruptly.

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

This time, the orange steel bars on the stone slab did not respond at all.

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

It's not easy, it's really not easy.

Everything in front of me is not so real.

It took more than five days of hammering, beating for more than twelve hours a day, and sleeping for less than six hours. Finally, a qualified steel bar was hammered out!

[This is steel? 】

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

[Am I really on Earth? 】

【So, Fang Shen really forged a piece of steel in the wilderness? 】

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

But the shocked expression on everyone's face told them.

That's right.

This is.

steel!
