Hand rubbing nuclear fusion live in the wilderness

Chapter 57

Next to the kiln, Han Yuan sat on a piece of bluestone, steadily turning the handle of the hand blower, sending fresh air into the kiln.

Sometimes if you shake it a little faster, blue flames will shoot up from the kiln.

After a while, the flame of the furnace began to change, and the blue flame turned into a bright orange-yellow.

This change aroused the curiosity of many viewers in the live broadcast room, asking why there are two different colors when charcoal burns.

Han Yuan shook the blower, smiled after seeing the barrage, and replied.

"At the beginning, not all the charcoal in the kiln was burned, and a large amount of carbon monoxide was generated, and the burning color of carbon monoxide was light blue, plus some other impurities, so the flame appeared blue."

"When it was later, all the charcoal inside had been ignited, and the color of the flame naturally changed back to the bright orange yellow of charcoal burning."

"If you don't believe me, look at the state of the charcoal in the kiln now."

As he spoke, he manipulated the shooting equipment to fly above the kiln, and then took pictures of the situation inside the kiln.

[Really, all the charcoal inside has been burned now. 】

[The stove is burned white, how high is the temperature inside? 】

[The chemical formula of the combustion reaction in the furnace is as follows: C+O=CO+C+O+high temperature=2CO+O=CO! 】

[What the hell is this writing upstairs? ? ? ? 】

[Thank you, I’m at the construction site, just finished moving the bricks, the upstairs means that charcoal burns to generate carbon dioxide, carbon dioxide reacts with carbon at high temperature to generate carbon monoxide, carbon monoxide is burned again, and carbon dioxide is generated, but his formula is not standard , points deducted! 】

[I'm completely confused, I just watched a live broadcast, but I still need to understand this? 】

[The burning temperature of charcoal can't make iron, right?Looks like the temperature is not enough. 】

[If charcoal cannot be used to smelt iron, the ancient iron weapons were sent by modern people with time machines. 】

[I'm looking forward to the day when the anchor makes airplanes, cars, chips, computers and nuclear bombs. 】

['Qingfeng and Mingyue' sent a super rocket*1, Ollie gave it, as long as you live broadcast for one day as the anchor, I will pay attention for one day! 】

It feels good to have someone to accompany, although it is just some barrage, but at least it can make Han Yuan feel that he is not alone.

Looking at the barrage on the virtual screen, he picked some questions to answer.

"Actually, the ancient people had mastered the principle of using charcoal to smelt iron and copper very early on."

"If you look at the combustion temperature alone, the combustion temperature of charcoal can reach a maximum of 1000 to [-] degrees."

"However, the melting point of iron is [-] degrees. Judging from the temperature, the burning temperature of charcoal cannot reach the melting point of iron."

"In this way, some friends may wonder, why can iron be smelted when the temperature is not enough."

"Although the melting point of simple iron is very high, ancient humans were also very smart. They added sulfur, phosphorus, silicon, manganese and other dissolved materials to iron ore powder, as well as the most important carbon!"

"In this way, the melting point can be lowered to about [-] degrees, and then using carbon as a reducing agent, iron can be exchanged from iron ore."

"This ironmaking method is called the 'low temperature ironmaking method', and it was the most used ironmaking method before blast furnace ironmaking came out."

After answering some questions, Han Yuan got up and took a look at the situation in the kiln. The charcoal was burning steadily, and the inside of the kiln was glowing white.

Seeing him get up, the audience in the live broadcast room thought that the iron in the kiln had been smelted, and became excited.

Unexpectedly, he just took a look at the kiln and then came back to continue shaking the blower.

Han Yuan glanced at the barrage of discouraged inquiries, and replied: "It takes a long time to smelt iron and iron. With the current furnace, it takes at least four or five hours."

"If you feel impatient, you can wait for about five hours and come back to watch."

As soon as these words came out, thousands of people disappeared in the live broadcast room instantly, and the number continued to decrease rapidly.

Seeing that the number of people has decreased, the Korean won doesn't care, it feels normal.

After all, people have to live and go to work.

The four or five hours of smelting iron in the furnace were very difficult, because he had to sit on a rock and shake the blower.

And every once in a while, I have to get up and look at the kiln, and then add charcoal to the kiln to keep the temperature stable.

Coupled with the high temperature around the kiln, it made him feel like he was in a steamer, and he was sweating profusely.

Even when the blower was being repaired, bamboo pipes were used to separate a certain distance, but the heat was still unstoppable.

A little bit of time passed, the sun rose and climbed into the sky.

After estimating the time, and then looking at the reminder from the audience on the bullet screen, Han Yuan also felt that the time was almost up, so he stopped and shook the blower.

He took the cowhide protective gear and tied it to his body to cover his skin and prevent the iron stars from splashing on himself when he was forging.

Seeing him start wearing cowhide protective gear, the live broadcast room finally became excited again, and the number of people began to increase rapidly.

[Here it comes, the anchor is finally about to start making iron. 】

【Waiting for five and a half hours! 】

[No wonder it was hard to find iron in ancient times, and it took too long! 】

[Open the furnace! 】

['Riding a pig into the world' sent out a super rocket*1, come back. 】

To forge while the iron is hot, Han Yuan put on the cowhide protective gear, immediately picked up a thick long wooden stick that had been prepared from the ground, and walked to the side of the kiln.

After five or six hours of burning, there were already cracks in the kiln, and the kiln was disassembled along the cracks.

A large piece of thick soil was removed and pulled to the other side, exposing the charcoal still burning in the kiln.

The heat wave was soaring, and Han Yuan used a wooden stick to pull away the burning charcoal, looking for the possible pig iron inside.

Suddenly, after pushing away some hot charcoal, a bright and incandescent hard object appeared in front of his eyes.

After pulling it with a wooden stick, it was confirmed that it was pig iron. Han Yuan suddenly became excited, put down the wooden stick quickly, and found a wooden clamp to clamp the incandescent and bright pig iron out of the kiln.

This is an irregular fist-sized piece of iron. After being clamped out of the kiln, it quickly began to cool down.

The incandescent color turned to dark red, which was hard to see in an instant, but it made Han Yuan and all the audience in the live broadcast room extremely excited.

【Ahhhhhhhhh! 】

[Success succeeded. 】

[The anchor is awesome, the anchor is high! 】

[Better than nobleman Zhao, nobleman Zhao took two times to make iron successfully, and the anchor did it once. 】

[I slapped my deskmate with a 'slap'!What book to read!Is reading useful?Show labor to see this now! 】

[Tomorrow I will quarrel with my husband and ask him to go to the wilderness to make iron for survival! 】

['I am not talented, the oil in the world' sent out a super rocket*1, watch the whole process, one word!Absolutely! 】

['Staying up late is addictive! 'Send plane *10, ojbk, enter the iron age! 】

[The tenth item in the history record table: 'The anchor harvested a piece of pig iron! ']

　It will be delivered in the middle of the night, please recommend, ask for a monthly pass, and ask the bosses to follow up.
