Datang: You Can't Imagine the Happiness of the Prince

"Supervisor, this will serve as a supervisor is a secret place, if..."

Wan Kuan smiled and asked Yu Shaojian to whisper next to him: "These two are from the royal family, if you are not satisfied, you can drive them away!"

"Supervisor Wan is joking!" Yu Shaojian smiled awkwardly.

That Princess Changle and Princess Wencheng were staying in the steel-making room where they were going to be prisoners. It was smoky and the air was full of cinders.

Most of the craftsmen inside are vests and jackets, and various burn scars can be seen everywhere on their bare upper arms.The craftsmen here are all tempered, so I don't believe Wan Kuan's statement at all.

Wan Kuan said at this time: "This official was ordered to supervise the manufacture of [-] horseshoes. How long will it take you to train the iron materials needed for these horseshoes."

When Yu Shaojian heard this, his face turned pale: "[-]? It will take three years and five years!"

"Huh?" Wan Kuan snorted coldly.

Then Yu Shaojian's face was bitter: "Supervisor, the billet used for this horseshoe must be made of fine steel, and there should be no dross in it, otherwise it will easily break during forging."

"Also, you have to be extra careful when forging. The hammer must be evenly forceful, the steel plate has to be leveled, and the black ash inside the steel has to be punched out until both sides are completely clean."

That old Feng slapped sideways and said, "This steelmaking is not something you can do with your mouth. The billet alone is a big problem."

Wan Kuan smiled slightly: "The billet of this horseshoe is not difficult to handle."

"What's the plan of the chief supervisor?" Yu Shaojian asked strangely.

"The method of frying steel is enough."

"The method of frying steel is fine, but we don't have such a big pot, and the amount of horseshoe is too large. It takes too much time to fry one pot at a time."

"Then we can raise the temperature of the furnace, and then use the blower to blow the wind in, so that we can train the billet of fine steel." Wan Kuan said lightly.

When Yu Shaojun heard this, his expression changed.I thought Wan Kuan was a rich boy and didn't know how to build, but when he heard Wan Kuan's words, he seemed to be an expert.

Wan Kuan knew in his heart that the fine steel billet was actually low carbon steel. The lower the carbon content in the steel, the better the plasticity of the steel.

However, the carbon in molten steel is not easy to remove. The method of frying steel is to use high temperature to keep the molten steel tumbling, and then keep stirring with a large spoon, just like cooking.In this way, the carbon in the steel reacts with the oxygen in the air to form carbon dioxide and fly away.

"Supervisor, we already have the blower for supervisors, but this furnace temperature is not so easy to mention." Yu Shaojian said.

"The fuel needs to be improved, and we need to use coke." Wan Kuan said.

"What is coke, we are all coal now."

What Yu Shaojian said was the bituminous coal in the open air. There are many impurities in the bituminous coal. When it is used as fuel, the flame temperature is not high.Wankuan uses coal to make coke, and then makes steel.

"Coke is made from coal. When the coal is incinerated, the impurities in the coal will be discharged. In this way, the coal will turn into coke, and when the coke is burned, the molten steel will tumble."

"This..." Yu Shaojian was a little surprised: "I don't know this method, but you can try it."

That old Feng looked at Yu Shaojian, his eyes full of doubts.

Then Shaojian Yu couldn't help but ask: "Supervisor, why is this kind of steelmaking method so small and unheard of?"

Wan Kuan smiled proudly: "This is Wan's steel-making method, and this official's original creation!"

Princess Changle and Princess Wencheng on the side stared at Wan Kuan blankly. At this time, Wan Kuan didn't seem to be the reincarnation of Wenquxing in Chang'an people's mouth, but more like an old-fashioned general.

At this moment, there was a sudden sound of footsteps outside the door.

"Supervisor Wan, this official has come to say congratulations!"

When Princess Changle and Princess Wencheng heard the sound, they immediately swish and hid behind the blast furnace.

Wan Kuan glanced at the door, and it turned out that Changsun Wuji was coming.

===第60章 玩弄老狐狸===

Zhangsun Wuji still had a warm smile on his face, but this smile was a bit dazzling in Wan Kuan's eyes.

"Eldest grandson Pushe, why do you always have time to come here to serve as a prisoner?" Wan Kuan cupped his hands.

"Where is the superintendent Wan, the purchases of this supervisor are all in the account of the household, and this officer naturally has to walk around often!"

"That's right, this official has to trouble the eldest grandson Pushe to buy more coal, and the superintendent will soon make a lot of steel!"

"Isn't this a coincidence?" Zhangsun Wuji laughed, "This official is here to convey His Majesty's will!"

"Your Majesty's will?" Wan Kuan narrowed his eyes.

Zhangsun Wuji was shy, and a pair of fat hands tapped on his stomach.

"Your Majesty means that within a month, the supervisor will make a hundred thousand kilograms of refined steel billets. And my household department has the right to cooperate with the superintendent Wan!"

"One hundred thousand pounds?" Yu Shaojian, who was beside Wan Kuan, widened his eyes.

"Who are you? Are you here to speak?" Zhangsun Wuji frowned, a little dissatisfied.

Wan Kuan frowned when he heard this: "This is an old craftsman who will be a prisoner. If the eldest grandson Pushe wants to get [-] kilograms of refined steel billets within a month, it's all up to him."

"A craftsman?" Zhangsun Wuji smiled, the contempt clearly visible in his eyes.

"Changsun Pushe, your Majesty's will is finished? Please come back after you've finished speaking. There is a lot of smoke here, so you don't have to dirty the official boots of Changsun Pushe!"

When Changsun Wuji heard this, he was stunned at first, but he recovered after a while.

"Supervisor Wan, it seems that you have misunderstood this officer! Last time, the dog and Superintendent Wan had some misunderstandings, but the grievances between the juniors will not be taken seriously by this officer."
