Hu Changan ignored everyone's doubts, and just ordered someone to raise the two stoves at the same time.

One side is heated with charcoal, while the other side is heated with coal.

On the side of the charcoal, a raging fire suddenly rose.

On the other hand, on the coal side, there is only a little red on the inside, and there is no flame at all.

Seeing this, everyone couldn't help muttering.

"Why is this coal burning not on fire? It seems that the coal provided by Hu Shilang is not very good. ”

"Can it still burn without fire? I'm afraid this Hu Shilang is not crazy, right? ”

"Although I am very convinced of Hu Shilang's operation last time, but this time he is simply betting on our Ministry of Industry. This kind of thing can't even light a fire, and it's ridiculous to say that it can be used like charcoal. ”

However, Hu Changan looked like an old god, just looking at the two stoves calmly.

Seeing that the burn was almost over, Hu Changan casually ordered someone to test the temperature on both sides.

When the man saw this, he was also very unimpressed.

Do you still need to try this kind of thing, anyone with a little eye can see it.

But at the moment, Hu Changan is the one in charge of this workshop after all, and his words cannot be disobeyed in public.

So the man had to pretend to reach for the two stoves, ready to probe the temperature.

However, it was this casual probe that shocked him.

The man tried back and forth a few times without believing in evil, and then he said tremblingly: "Ladies and gentlemen, it seems that the temperature of the furnace that burns coal is relatively high. ”

What?

Everyone immediately blew up.

Even the open flame did not rise, and it was said that the temperature of coal was higher than charcoal?

I'm afraid that person doesn't want to please Hu Changan too much, and he dares to talk nonsense with his eyes open?

Ma Shi was the first to not believe it, rolled up his sleeves and walked to the two stoves, feeling the temperature of the two stoves carefully.

The charcoal-burning stove was at a temperature he was familiar with, and it was normal.

After all, Ma Shi is also an old craftsman who has worked for decades, and he knows very well what temperature charcoal burning can produce.

However, when he walked over to the coal-burning stove, his eyes widened in surprise.

This temperature seems to be higher than that of charcoal?!

Ma Shi walked back and forth between the two stoves several times, and finally established a fact.

Burning coal is really hotter than burning charcoal!

Ma Shi was stunned, and then shouted to everyone in surprise: "The old man has tried it, and the temperature of burning coal is really high!" ”

This sound, as if boiling water was poured into hot oil, completely fried the pan.

They can not believe the words of the first person, but Ma Shina is a respected old-timer, and it is impossible to lie!

Everyone was so shocked that they forgot even the most basic etiquette, and surrounded them with a hula, carefully feeling the temperature of the two stoves.

At this point, facts speak louder than words, and it's really just that the furnace where coal is burned is hotter!

Everyone couldn't help but feel a little hot.

This time, I'm afraid that they will spend the belly of a gentleman with the heart of a villain.

Hu Changan, who is that, that is a rising star who is more powerful than these old-timers, an absolute iron-making master.

How could he promote something bad because of a little grudge?

It turns out that as long as Hu Changan takes out something, it is a good thing!

Everyone's worship of Hu Changan couldn't help but deepen again.

Looking at the fiery eyes of these craftsmen, Hu Changan also smiled slightly.

These craftsmen are still quite rustic, as long as they can come up with more advanced technology, they will completely convince you!

Unlike the deceit in the court, this made Hu Changan feel very relaxed.

Just when everyone was shocked, Ma Shi suddenly asked out loud: "Hu Shilang, I don't know what the special substance you used on the day of the competition, is it this mineral?" ”

As an old craftsman who is obsessed with ironmaking, Ma Shi privately approached Hu Changan on the day he was defeated by Hu Changan and asked him for the secret recipe of ironmaking.

However, at that time, Hu Changan just smiled at him, saying that the time had not yet come, and it was inconvenient to reveal the specific information of that ore to him.

Now when Hu Changan took out this new ore, Ma Shi reacted immediately.

Could this be the new mineral that Hu Changan mentioned at that time?

"Yes, the last time I put coke in the furnace, it was formed by burning coal." Hu Changan smiled slightly, and also generously recognized Ma Shi's words.

Ma Shi was overjoyed when he heard this: "Hu Shilang, this new ore is simply the treasure of ironmaking!" It can be used as fuel, and can be put into the furnace as a raw material for ironmaking, and it can be used for multiple purposes! ”

Looking at the burning coal, Ma Shi seemed to see a peerless beauty: "Hu Shilang, I wonder if the residue of this coal after burning can be directly thrown into the furnace as a raw material for ironmaking?" ”

When Hu Changan heard this, he smiled slightly: "Mr. Ma, your idea is very good, but it can't be realized." ”

"When coal burns in the air, it binds to a particulate in the air."

"Since coal has been combined with one particle, it naturally cannot be combined with another particle in the ironmaking process."

"So, coal that has been burned in the air does not speed up the process of iron smelting."

"But when the coal burns in isolation from the air, it can't continue to bind to the airborne particles, and only then can we get the pure reducing agent, which is the coke I put in the furnace last time."

"So when we make coke, we have to let the coal burn without air."

"Just putting the coal in a small jar that keeps out the air during combustion can solve this problem very well."

Ma Shi couldn't help but be impressed: "Hu Shilang, it's too simple to think about it!" In the future, everything in my ironmaking workshop will depend on your care! ”

When Hu Changan heard this, he also smiled modestly and said, "Everyone, there is no need to be arrogant. We are all the same people, as long as you master the knowledge of physics and chemistry that I provide, you will definitely be able to improve the ironmaking process with the same ease as I am in the future. ”

"Even my experience is not as good as yours, if you learn the knowledge I provide, you will definitely be better than me in the future!"

Listening to Hu Changan's sworn words, everyone couldn't help but be short of breath.

Although they couldn't understand what physics and chemistry were in Hu Chang'an's mouth for the time being, this did not prevent them from imagining the future.

Could it be that one day in the future, they can call for wind and rain like Hu Shilang, and directly double the iron output of the workshop while talking and laughing?

If that's true, that's great!

Among them, Ma Shi was moved almost to tears.

As a man who has been fighting iron all his life, how much he wants to learn the techniques mentioned by Hu Changan in his lifetime!

Chaowen said, you can die at night!
