"There are a lot of things going on today."

"First go to the Ministry of Industry to get the warrant, and then go to the Firearms Research Institute to deliver the book."

"Finally, let's go to the work department workshop together."

Yang Yiming's eyes lit up.

"Brother Zili asked for leave from my father?"

Jia Cong smiled and said: "Of course."

The two of them hurriedly got into the car and went to the Ministry of Industry first.

The Sixth Department is not far from Dali Temple, Hanlin Academy Hospital.

Of course Jia Cong and Yang Yiming often come and go.

The newly appointed Minister of Industry, Mo Fei, is a few years younger than Jia Jing, Jia She and others.

When Jia Cong explained his purpose of coming, it also contained the wishes of Emperor Tianxi.

Although it was not a formal oral order, Mo Fei quickly wrote the warrant.

He asked with a smile: "My young prince, do you want to send a chief officer or a member of staff to follow you?"

As soon as Jia Cong heard that the director of the Ministry of Industry was a member of the Ministry of Industry, he immediately thought of his second uncle Jia Zheng who had disappeared.

He quickly handed over his hands and thanked him: "Thank you, Mr. Dongguan. There is no need to send anyone to follow you."

"We have to go to the Firearms Research Institute to pick up Yuan Wai Lang."

Mo Fei smiled and said: "Well, little prince, Yang Hanlin please do it yourself."

The car was rolling, and soon we arrived at the Firearms Research Institute.

Dai Yuan saw Jia Cong and asked quickly: "Brother, are your uncle's eyes better?"

"Is there any hope for recovery?"

He sent Xu Bijiang back to Xu Mansion yesterday, but did not go in.

So I don’t know what happened next.

Jia Cong said in a deep voice: "Later, someone from the Taoist sect appeared and sent my uncle to Longhu Mountain."

Dai Yuan said angrily: "It's all my fault..."

"If I hadn't been looking for a book, Brother Chaozong wouldn't have left the palace through Donghua Gate..."

"If you come out of the Dahong Palace Gate and are protected by Brother Qi, maybe it will be more than that..."

Jia Cong gave two books to Dai Yuan.

"Uncle Dai Shi, it's not what you want to do."

"This is the book you asked your uncle to find yesterday. I brought it for you."

"Do you have time to go to the work department workshop together?"

Dai Yuan said: "Okay, let's go and see it together."

"It's not that far anyway."

"I also went there a few days ago."

Production departments such as the Work Department Workshop, the Ordnance Bureau and the 24th Yamen War Bureau are all located in the northern suburbs.

Not far apart.

So after leaving the Firearms Research Institute, it doesn’t take long to arrive.

While still outside the work department workshop, I felt a rolling heat wave coming.

There is also a camp of guards outside the workshop guarding the place.

Jia Cong ordered Zheng Duofu to deliver a warrant to the Minister of Industry.

Only then can we enter.

At this time, Dachu already had a blast furnace for ironmaking.

The method of making steel is still the steel frying method.

The semi-melted molten iron is constantly stirring in the crucible.

The blower whirred, feeding the concentrate powder.

All the craftsmen went into battle shirtless, leaving scars of large and small burns on their bodies.

Seeing Jia Cong and others coming in, the craftsman raised his head and glanced briefly, then continued his work.

After receiving the news, the workshop manager of the work department rushed out to see the gift.

"The lower official has met the young prince, Yang Hanlin, and Dai Yuanwailang."

Jia Cong asked: "Can medium-carbon steel and high-carbon steel be made now?"

The manager of the Ministry of Industry said softly: "It depends on luck, the output is very small."

"Especially Dai Yuanwailang's requirements cannot be met at all."

Jia Cong glanced at Dai Yuan in surprise.

"Uncle Dai Shi, have you actually thought about using steel to replace the copper barrel?"

Dai Yuandao: "Of course I have thought about it, after all, the cost of copper casting is too expensive..."

Jia Cong walked around the workshop.

See that blast furnaces use coke instead of charcoal to make iron.

The temperature is enough to melt molten iron.

The thoughts in my mind are racing.

Yang Yiming followed Jia Cong and watched.

Such low carbon steel cannot be used to make a gun barrel, of course he knows.

The Mauser rifle barrel that day was removed from the original Ferguson rifle.

It is also forged from wrought iron.

It’s not just a steel barrel.

At this time, I saw Jia Cong walking more and more hastily, walking faster and faster!

Yang Yiming didn't know what Jia Cong was thinking, and it was hard to disturb him.

Just follow him in circles.

Dai Yuan looked dizzy.

Just as he was about to speak, Jia Cong suddenly clapped his hands together!

Now that we have coke, why not just create open-hearth steelmaking?

The smelted steel is enough to make a gun barrel.

Even the gun barrel is possible!

As for the converter, that thing is still not available.

Jia Cong shouted in a deep voice.

"Director of the Ministry of Industry, please call the most experienced craftsman from your workshop!"

The director of the Ministry of Industry quickly called out two shirtless men, an old man and a young man.

Jia Cong saw that the temperature in this workshop was extremely high.

Take the two of them out of the workshop first.

I took out a pen and paper and drew a simple diagram of open-hearth steelmaking.

The furnace is a trough made of refractory bricks, which is covered by a furnace roof made of refractory bricks.

There is a charging port on the front wall of the open-hearth furnace, and the door made of refractory bricks is closed during smelting.

There are burners at both ends of the furnace, and the burners each have two holes.

It is used to introduce fuel and hot air, or to guide furnace gas from the furnace.

Jia Cong pointed out the functions of each part one by one.

Then he said: "Making such an open-hearth furnace should be able to achieve mass production."

Yang Yiming looked at Jia Cong in surprise.

"Brother Zili, how did you think of it?"

Jia Cong said: "An old man with a white beard told me in my dream!"
