Chapter four hundred and ninety seventh wrought iron
"Is this iron?"
"It's iron!"
"It's really iron!"
"Damn it, it worked, it really worked! Bi Fang has mastered it!"
In the first venue, the crowd cheered.
Someone even exploded fireworks on the spot, and streamers fell from the sky and landed on everyone's heads.
"Success!"
"Damn it, where did the fireworks come from?"
"Thirty-six yuan each. They sell it in the small store next door. They say it's a physical reward..."
【This is a miracle!】
【iron!!!!】
[With so much charcoal, how many mutton skewers are needed?]
[The temperature is absolutely ridiculously high!]
Bi Fang used a long wooden stick to pick up the iron ingot, but the bottom seemed to be firmly stuck, so he had no choice but to take it out together with the furnace bridge.
At the moment when the furnace bridge came out of the land, the camera zoomed in quickly and saw only the uneven black iron blocks above the furnace bridge, with red light glowing in many places, flickering like metal breathing.
Hold the stone and smash it hard, and it will deform almost visible to the naked eye. This is an almost melting state...
Amazing.
Audiences at home and abroad were amazed.
Before Bifang, no one had ever been able to go deep into the jungle alone and refine iron with nothing like him...
too exaggerated.
In comparison, those who find "wild ores" and bring them to factories for refining are undoubtedly a piece of shit!
This is not about teaching people how to survive in the wild or how to use hands-on skills. It has reached the point of how to rely on wisdom to re-establish human civilization without the products of modern civilization at all!
The emergence of Tie has made Bifang's live broadcast completely different from the past.
In the past, it could be said to be a simple survival in the wilderness, but now, it is completely different.
From catching fish to chicken soup, from single-slope sheds to shelters with walls and roofs, to raincoats on rainy days.
Various stone tools, salt, and now iron.
All daily necessities are available, and even more high-end materials have appeared.
No one doubts that if Bi Fang had not packed a pair of shorts or a grass skirt when he got off the plane, but had brought a bag of wheat seeds...
No!
Maybe he only needs a piece of potato, or even no potatoes. If he is given more time to search, he may not be unable to find a stable source of carbohydrates that can be planted!
【GOD!】
[God cannot condense a piece of iron in the wilderness]
[This is the birth of civilization]
[Messier gives 10 spaceships to the host - respect civilization! 】
[Fat Cat Pete presented a yacht to the anchor*1 - Respect for civilization! 】
[Pork heart and shrimp meatballs are presented to the anchor*66 - Respect for civilization!]
[I don’t have money, but! Respect civilization! Let’s give God Fang a small salute! 】
[What I’m watching is not a live broadcast, but the evolution and process of human civilization]
The audience was even more excited and almost spoke without hesitation. Anyone who has experienced the process of more than ten days and witnessed the birth of iron with their own eyes would be like this...
Six million spectators witnessed this scene and witnessed what civilization and wisdom are.
Which comes first, the thought or the object?
There were no tables and chairs in China before, not because of lack of materials and capabilities, but because there was no concept of tables and chairs.
The most valuable thing in the world is not oil and gold mines, but human thoughts.
Thoughts are more precious than gold and diamonds. They are the most precious wealth of the entire human civilization. Anyone who wants to imprison people's thoughts will definitely suffer backlash in the end.
"You are so excited. Of course, I am too."
His heart beat violently, causing Bifang to start panting.
He explained: "But my goal is not only to make iron, remember what I said at the beginning? To make an iron tool, at least a dagger."
"I somewhat overestimated the production of iron bacteria."
Bi Fang put his hand next to the iron block. At this time, with comparison, the audience realized how small the reddish iron lump was.
Only as big as a fingernail!
This is obviously not enough, and it is far from the requirements of Iron Sword.
"Originally, I thought ten pieces of earth cake would be enough, but now five pieces are only as big as a fingernail. It seems that it is not enough, but there is no need to worry. In addition to the yellow iron bacteria, I also dug rusty soil later and made it with rusty soil.
The iron content of the soil cake is higher, which is enough to surprise us."
Gu Shi
Bi Fang kept taking deep breaths to calm down his excitement.
It's far from over now. After making iron, we still have to forge it.
"The slime secreted by these iron bacteria is mainly composed of iron hydroxide. I added charcoal as the reducing agent C and plant ash as the co-solvent K2CO3. The three were mixed into a clay body and put into the furnace to be fired at high temperature. Only then can I successfully practice it.
Iron comes."
"The plant ash is decomposed into potassium peroxide and carbon dioxide under high-temperature roasting. Together with the carbon dioxide produced by combustion, it reacts with the charcoal to form gaseous carbon monoxide. The carbon monoxide eventually reduces the clay that is already iron oxide to obtain elemental iron."
"If we smelt all the iron out, it will be difficult to melt it. At this time, it is already pure iron. Although there may still be many impurities in it, it is no longer comparable to the original powdered iron oxide.
"
The original plant ash is a powder, and the iron oxide is also a powder. They blend with each other and the reaction is natural and simple.
Bi Fang hit the black lump in front of him with a stone and knocked out all the iron blocks inside. He was somewhat surprised.
The iron lump is not only the one on the surface, but there are two smaller ones inside, which together are as big as a knuckle. In addition to these three lumps, there are also many small iron sands, but the total is not much.
How many.
Bi Fang immediately struck the iron while it was hot, put five pieces of earth cake in again, and continued refining.
"Don't put too much earth cake in at one time. Too much may result in half the effort and insufficient combustion reaction."
Until the evening, Bi Fang made a total of twenty earth cakes and obtained an iron ingot slightly larger than his index finger.
I weighed it in my hand and found it was very heavy.
【Is that enough? I feel...】
【It should be almost flattened?】
Bi Fang shook his head: "It's not enough. All I can make is a blade. What's the use of a blade? Can I shave?"
Touching the stubble on his face, Bi Fang was amused by his words.
"What I want is a knife with practical functions. It must be at least a dagger. Not to mention that there are many impurities in it. When the iron is forged, the size will be further reduced."
In the next two days, Bi Fang continued to smelt iron, and went hunting with his bow and arrow. He caught a snake and a hare, and also fished back fish from the fishing ground.
It is the sixteenth day of survival in the Banna Rainforest, and there are still five days left before the end of the mission.
"Hello!"
As soon as the fish was poured into the puddle, the water monitor lizard ran over out of habit and was scared away by Bifang's spear.
After living together for a long time, the water monitor lizard became more and more bold. Bi Fang dared to come over to feed while he was still at the water hole. He didn't care, he was not blind.
I was beaten hard with a stick last night, and I was beaten to death in a muffled voice. Today I have become a little more honest.
[Does it sound good? If it sounds good, it’s a good start]
【Hahaha!】
When we arrived at the shelter, there were already dozens of large and small iron ingots on the ground. In many cases, a piece of earth cake might produce several broken pieces, some as large as the size of a knuckle, and smaller ones.
No matter how big a fingernail is, no matter how small it is, the pieces are as big as a bean.
Bi Fang gathered all the iron in his hand, and could barely hold it in one hand.
It's very heavy. In terms of weight alone, it's almost a kilogram!
Even if the wear and tear is taken into account, it still weighs one kilogram, or 500 grams.
The weight of a tactical knife is generally only about 400 grams, and that includes the overall weight of the handle. This pound is enough to forge a dagger.
The only problem is how to forge it. He doesn't have a hammer, only a stone hammer...
There are stones that are harder than iron, such as quartz and pealite, but they are hard but not tough and can be easily broken.
Do you have to break your arm to do this?
Let's try again then. Bi Fang shook his head and wanted to see if he could melt these iron blocks first and cast them into molds for forging directly. That would be much simpler, at least simpler than forging them directly.
With only the last five days left, Bi Fang already had a sense of urgency. He originally found the iron bacteria and thought he had more than enough time, but he didn't expect that the real challenge lies in making knives!
After bringing all the iron with him, Bi Fang went back to the blast furnace, put the iron pieces into the pottery bowl, sprinkled plant ash, spread firewood around and lit it, and then kept adding charcoal. The whole process was the same.
At this time, the audience no longer cares about whether they can make the iron sword. They have no systematic task assignments and no sense of urgency like Bi Fang. The moment Fang Shen made the iron, they felt that it was complete.
The white smoke stops.
After Bi Fang opened the stove lid, he took out the pottery bowl.
Fortunately, the scarlet iron has a tendency to melt, but it is only a tendency. Only the iron sand at the bottom of the bowl really begins to melt.
Hundreds or thousands of iron sand, less than one-third the size of a grain of rice, melted together and stuck to the bottom of the bowl.
"If you want to completely melt a large piece of iron, the conditions are still not good enough." Bifang raised his head and looked at the two-meter-long chimney.
The current conditions are not enough and must be further improved!
"The chimney needs to be further raised to three meters, and we also need to make a blower. After that, it's almost done."
Throw the iron piece into the bowl and do it as soon as Bifang says.
Go to the river again, dig clay, wash the clay, build a high chimney, and then make a blower.
Making a blower is very simple.
"The main components are the internal fan and the external shell that restricts the airflow."
Bi Fang took two pieces of hard bark, each piece was twenty centimeters long and five or six centimeters wide. He cut a groove in the middle of each piece, aligned them with each other and inserted them. A cross-shaped fan blade was completed.
Then take a thin wooden branch, peel off the bark, make a cross on one section with a stone dagger, divide it into four small petals, and insert it into the center of the fan blade.
Both ends of the fan were tied with fiber ropes to ensure that they would not fall apart due to material problems. Bi Fang held the long pole and rubbed it. He tried it next to the campfire and found that the wind was strong.
The next step is to use clay to make a shell on the outside of the fan blade to collect the fanned airflow in an air outlet.
