144 Steelmaking

Pingguo, iron factory.

Gao Fei has been here for almost five days. During these five days, he spent a lot of effort to transform the iron factory. Without changing the functions of the original iron factory, he had another steel-making furnace built.

.

After the completion of the steel-making furnace, Gao Fei had already had the small amount of iron ore and coal needed transported from the iron ore and coal mines, and began experimental smelting.

On this day, the sun was high in the sky, and people were standing near the iron factory. Most of them were workers who had returned to work in the iron factory, and local people who came to watch.

In accordance with local rules, Xun You set up a sacrificial platform around the steel-making furnace to offer sacrifices to ghosts and gods and pray for their blessings.

Gao Fei has no interest in sacrifice at all, but he has to admit that this kind of sacrifice is very effective for the locals. At least everyone except him believes in gods, just like all the people believe that he is the reincarnation of Ziwei Emperor Star.

.

He has been checking every joint to see if there are any omissions. This steel-making furnace was designed by him personally. Below the steel-making furnace is a large room filled with flammable wood and grass, as well as bedding.

Some coal was added. Above the room is a long chimney, which is as high as three stories.

There are four large blast boxes outside the steel-making furnace. Pang De, Hua Xiong, Tai Shici and others were all standing guard around the wind boxes, just waiting to light the steel-making furnace.

The steel-making furnace has also been baked at low temperature for a long time and is now waiting to be ignited. There are many soldiers holding shovels standing at the loading port next to it, ready to stuff the coal and pig iron that has been smelted in the iron factory at any time.

When the sacrifice was completed, Xun You walked to Gao Fei's side and said respectfully: "My lord, everything is ready, just waiting to be lit."

Gao Fei nodded and shouted to the soldiers beside him: "Bring the torch!"

The soldiers nearby handed Gao Fei the torch that had been prepared. Gao Fei lit the torch himself, walked to the feed port of the steel-making furnace, and threw the lit torch in.

Steel-making furnaces are filled with flammable materials, and when they encounter sparks, they will immediately ignite.

The fire gradually began to spread, swallowing up all the flammable materials in the steel-making furnace.

After a while, the blazing flame started burning, and the coal inside was burned. As the fire inside the stove became more and more intense, a burst of black smoke slowly came out from the top of the stove.

The black smoke was getting thicker and thicker. Gao Fei waved his hand and immediately shouted: "Hua Xiong, Pang De, Tai Shi Ci, Zhou Cang, pull the bellows."

"Okay!" Hua Xiong and others shouted at the same time.

Hua Xiong, Pang De, Tai Shici, and Zhou Cang opened the blast box at the same time, driving the coal fire in the steelmaking furnace to become more and more intense. After a while, all the black coal began to turn red.

At this time, the smoke coming out of the chimney became larger and larger, and soon became smaller and smaller, and the red fire began to emerge from it, bringing out ashes flying all over the sky.

As the bellows was pulled faster and faster, the flames on the top of the stove were getting higher and higher. Gao Fei estimated that the fire was almost done, so he shouted to Liao Hua and others who were standing at the loading area: "That's it, load the ingredients!"

Liao Hua agreed, and then led his people to start adding coal to the steel-making furnace.

After adding the coal, they started to add the iron ore and limestone piled next to them. The iron ore and limestone were smashed into small pieces the size of walnuts. After loading 12 stones of ore and some limestone, they stopped.

Such repeated loading operations continued for several hours. When people got tired, they would be replaced and they would take turns.

"It's a pity that there is no water source here. Otherwise, we can use water to do some tedious work and save a lot of manpower. But this is the first trial. After a furnace of steel is made, a lot of manpower may be saved.

Got it." Gao Fei said to himself after seeing this situation.

Xun You felt quite novel about Gao Fei's construction of a steel-making furnace. He always felt that there was something in Gao Fei that surpassed his predecessors, but he couldn't guess it. After looking at Gao Fei for a while, he slowly said in his heart

: "What kind of person is my lord? Why does he know so much and seem to be able to solve everything easily in his hands?"

"Lord, how long will it take to burn with this method?" Xun You turned his head, glanced at the steel-making furnace, and asked.

Gao Fei said: "What steelmaking requires is time, and it may take a long time, not to mention this is our first time making steel. Let's go and let everyone go back to rest. I will leave two hundred soldiers to station here.

, you can just come and see the results tomorrow morning."

Xun You nodded and said softly: "My lord, you have been busy building the steel-making furnace these days, and you haven't had a good rest for several days. Why don't you let your subordinates watch here while my lord goes back to the county office to rest."

"

"No, you don't understand these things yet. I have to watch them myself. If something goes wrong, my time these days will be wasted." Gao Fei said.

"But my lord, you are the lord of all peoples, and you shoulder great responsibilities. If anything happens..." Xun You comforted you.

"Don't worry, I know my own body. It's hard work these days. As long as the first batch of steel is smelted, the rest will be easy. In addition, call the blacksmith directly. Once the steel is smelted, we can get the materials locally.

Forge, strike while the iron is hot and forge weapons."

"promise!"

The steel-making furnace kept burning for nearly 20 hours. Early the next morning, Xun You and his people came again to see the results of the steel-making furnace.

Gao Fei had someone start up the mixing furnace and heated it for more than an hour. When he saw that the temperature of the mixing furnace had risen to about the same level, Gao Fei removed the blocking stone blocking the taphole.

, use a long iron drill to break open the clay blocking the taphole, and a stream of orange-red molten iron follows the groove on the ground, passes through the preheating chamber, and enters the mixing furnace.

There was cheering all around, and the hard work for several days finally paid off.

Gao Fei didn't have time to cheer. Seeing that it was almost done, he quickly blocked the tap hole with stones and clay. The mixing furnace could not hold so much molten pig iron at one time. After the molten pig iron entered the mixing furnace, Gao Fei opened the tap hole.

The furnace door of the mixing furnace. Due to the effect of the high chimney draft, the flame only sprayed out and then retracted. The high-temperature air rolled from the combustion chamber was reflected by the furnace roof and directly hit the pig iron on the hearth.

On the surface of the water, there are dots of light.

Gao Fei picked up a long stirring rod made of wrought iron and stretched it in from the mouth of the stirring furnace, stirring the molten pig iron inside. The molten pig iron was stirred and came into contact with the high-temperature fresh air, and the carbon inside and the air

The oxygen reacts quickly to release huge heat and bubbles appear.

The molten iron began to boil, rolling around, and the iron slag, which looked like tofu dregs, separated from the molten iron and piled aside. As the purity of the iron gradually became higher, the melting point also increased, and the molten iron slowly rolled to form a lump.

A lump of semi-solid jelly material, which then condenses into agglomerates, and spots of mature iron are formed on it.

Goofy used the stirring rod to hook the iron balls to the furnace mouth, and shouted: "Blacksmiths! It's time for you to play your role!"

The blacksmiths who had been standing near the steel-making furnace heard Gao Fei's shout, and quickly used iron pliers to take out the iron balls and put them directly on the roaring large forging hammer. As the forging hammer struck at high speed,

Sparks flew out of the iron ball, and the dregs inside were quickly squeezed out, turning into sparks and flying away. The size gradually shrank, and the color gradually became orange-red and gradually darkened, forming an iron rod.

The blacksmiths put the iron rods on the forge nearby to heat, preparing to forge them again, and then took out another iron block from the mixing furnace and repeated the operation.

Taishi Ci was watching from the side. Seeing that Gao Fei was very tired, he quickly went up and took the stirring rod from Gao Fei's hand and said loudly: "My lord! You are too tired. Go and rest for a while. Let me do it here!"

"

"You need to cooperate more with the blacksmiths!" Gao Fei shouted loudly, and handed the mixing rod in his hand to Tai Shici.

Gao Fei walked aside, sat down on the ground, and never wanted to get up again. He wiped the sweat from his face with his sleeves, and stared at Taishi Ci and the blacksmiths closely.

Gao Fei sat aside and saw Taishi Ci practicing the operation of gourd and painting ladle, so he kept shouting to him and giving instructions. After a while, Taishi Ci was also tired, so Pang De took the hand from Taishi Ci.

Everyone took turns doing the work. The blacksmiths were responsible for hammering the iron blocks placed in the forge to meet his requirements.

Gao Fei regularly asked people to put molten iron in and replenish the mixing furnace.

Hua Xiong and a few people were still adding charcoal, iron ore and limestone to the blast furnace one by one according to the time, and under Gao Fei's shouts, the slag was discharged regularly. After a while, with the active cooperation of everyone, the ground was already

Piles of halberds made of pure steel.

"It's so fast!" Gao Fei said excitedly while wiping his sweat.

There were more than half a ton of halberds on the ground. By noon, the soldiers in charge of the steel-making furnace had basically mastered the techniques of stirring and forging steel. Several people rested next to the blast furnace, taking turns to continue working. At the end of the day, steel-making

The number of raw materials piled beside the furnace decreased, but the number of steel halberds piled increased.

In the evening, Gao Fei felt extremely happy when he looked at nearly three hundred steel halberds. He picked up a steel halberd that had been cooling for a long time and started dancing excitedly.

After the first furnace trial was successful, Gao Fei built several steel-making furnaces near the iron factory, so that all the blacksmiths could work and forge steel guns, steel swords, steel knives, and steel according to his wishes.

halberds and steel arrowheads, and let Gongsun Kang and Xiahoulan be responsible for transporting coal and iron ore from various places. The Pingguo Steel Plant was temporarily used as the forging base, and Liao Hua was responsible for the daily affairs of the steel plant.

On the other hand, Xun You was responsible for the mining of gold mines. After the industrial affairs in this area were resolved, Gao Fei took Tai Shi Ci, Hua Xiong, Pang De, Zhou Cang and others back to Liaodong City to prepare to start training the new recruits.

military.

(Author's note: The content of steelmaking involved in this chapter is not true. It is just my own imagination. I hope that readers will not take it seriously. After all, I am not specialized in steelmaking. I can just treat it as a kind of yy of mine.)
