When I was a child, my family collected a set of 100,000 versions of the leather version, which came in handy at this time. Early the next morning, I tried to recall for half an evening. The next day, Wang Hou tossed the cobbler and carpenter in the mansion again, and added the last missing component.

Bellows.

He dismantled a large box, inserted two pull rods, and pasted a piece of cowhide inside. The thing was done. The built iron smelting furnace was opened again, and a ventilation duct was built on bricks and cement. Wang Hou couldn't wait to order the furnace to refine iron ore.

The large coal blocks that had just been burned for a day yesterday came in handy. The dirty and unbrightened large coal blocks were moved to the stove piece by piece amid Wang Hou's shouts. The iron ore that was pulled back yesterday was also thrown in, and lime was sprinkled as reaction medium. However, before Wang Hou could order the fire to be ignited, he kept pinching his chin and frowning, and the blacksmith head that General Cao ordered to send him suddenly clasped his fists on the side.

"Hand up!"

"oh?"

Wang Hou was surprised and asked in surprise as his eyes fell on the muscles that had been smelted on his face.

He was obviously a little nervous. After all, even a small official like Wang Hou was very different from his servant, but this guy was very craftsman-like, so he still asked with his fists.

"I wonder if the head of the family opens the road furnace to create agricultural tools or weapons? If it is to create agricultural tools, charcoal will be enough. But if it is to create weapons, the villain has used charcoal to refine many batches, and it is brittle every time. Please give the head of the family a clear guide."

This guy knows a lot. After looking at him with a high look, Wang Hou smiled casually and said, "It's okay, just create some farm tools."

He showed a look of disappointment, but the muscle blacksmith didn't say much, and bowed and retreated with his fists.

This time, it was not the honeycomb coal ignited, but it was completely a good charcoal block that was thrown into it. Even so, it took a long time to ignite it. However, together with the fire, the advantages of coal were fully demonstrated. The hot temperature suddenly came out along the furnace mouth. The charcoal fire could reach up to 1,000 degrees, but the coal fire could reach more than 2,000 degrees. The nearby ice and snow that were roasted by the heat melted at a speed visible to the naked eye. The large and small pieces of iron ore with uneven mass cracked quickly and spread out crackled.

"Why are you still standing there? Blowing!!!!"

If the leaders always curse people! Without the eyesight, Wang Hou shouted speechlessly as he watched Wang Ganzi and others standing there stupidly, but this sentence made them even more helpless. Wang Hou personally grabbed the simple bellows and held the hand, and filled the strong wind in with sufficient supply. The already vigorous flames were even steaming. The hot people could not even stand at the furnace mouth, and the forced one could only retreat.

Seeing Wang Hou pushing the bellows with sweaty head, the blacksmith head, whose face was full of muscles, just now, his eyes lit up. He followed with two steadily, and he also pushed the second blast furnace inward and then rushed in brightly. At this moment, Wang Ganzi woke up as if he was dreaming, took the bellows in Wang Hou's hand and the two blast furnaces were thriving together in the gangster Heat. Wang Hou could finally take a step back.

He pinched his chin and stroked the mustache that had finally grown after a long time. Looking at the black smoke squirting from the blast furnace in front of him, Wang Hou's eyes once again shone golden light, and his hands kept rubbing.

The fuel is not good, is it okay for steel products? The days when you eat steamed buns and throw them one by one, and drink soy milk and pour them one by one, all depends on this iron lump!

…………

The furnace ironmaking process initially requires two steps. The first step is the block refining method. After the first furnace burned for several hours, the non-metallic stones burned in the heat and almost collapsed. The boiling furnace ash was pulled out. Under the burning of hypoxia, the coal produced a large amount of carbon monoxide and reduced iron elements in the iron ore. Pig iron blocks with irregular slags on the outside had appeared in the slag ash.

I didn't think it was true that I pulled out the iron from the slag ashes, but the two pieces of pig iron that were still a little hot to each other hit each other twice. The head of the blacksmith, who had muscles on his face, immediately showed surprise. He took the tempting pig iron block in his hand in a long time of incredible moments, then suddenly went crazy, and threw it into the basket one by one, one by one.

In the West, in the meantime, it was still burned with charcoal blocks. At a low temperature of less than a thousand degrees, sponge iron filled with honeycomb pores and impurities were refined. Then, relying on the hammer of the blacksmith to repeatedly hammer the sponge iron to produce impurities, the processing of the iron tools was completed. However, it was indeed a rising star. The Renaissance was in just two or three hundred years, and the smelting technology evolution from the Han Dynasty to the Qing Dynasty was completed. It immediately completed industrialization, completely surpassing the East.

Fortunately, with Wang Hou, the smelting industry of the Han Dynasty led by Wang Hou has been improved.

Wang Hou, who had made the blast furnace start to cool down, got a pile of pig iron, was not busy continuing to smelter. Instead, he directed the workers to continue to get busy. Taking advantage of the current heat of the high crying furnace, he cooked up the frozen soil around him. He personally took up the shovels and quickly dug two square grooves, two meters long and wide, half a meter deep, and square grooves were dug out next to the two blast furnaces.

The bottom of the pit was completely paved, and Wang Hou was not satisfied. He asked someone to move bricks and build a layer of flatness with cement on it, just like two small swimming pools. Only then did he be satisfied.

However, after all this, it was almost dark, and the cement had to be air-dried for a while. After lighting a coal stove nearby, the day ended here.

…………

Wang Hou, who did not sleep until the early morning, was forced to quit the Internet addiction in the late Han Dynasty, who had no mobile phone, computer, and even TV. He developed the habit of going to bed early and getting up early. After eating at five o'clock, he went to bed and went to bed at around six o'clock. However, it was only 5 o'clock the next morning, and he was already full and got up.

However, there were more active than him. In the morning, when Wang Ganzi, who was still yawning, was dragging more than ten strong men in the mansion. When he arrived at the iron smelting furnace at the edge of this coal mine area, the muscle blacksmith had already arrived there. He pinched his chin and frowned and frowned, he couldn't help but study the two big gourd-like blast furnaces. He was fascinated until Wang Hou patted him heavily from behind and then woke up.

"Ah! The villain greets the head of the family!"

"What's your name?"

They were all employees of his own, and they didn't even know the name. Wang Hou was a little embarrassed. Fortunately, he was the master, so he was right. He pretended to be thirteen and held his hands and thrust his belly. This guy looked like a leader inspecting and waved his hands carelessly. Although he looked like a blacksmith was over 1.8 meters tall, he had to hurriedly clasped his fists and replied respectfully: "Go back to Master, Little Man Pu..., Little Man Wang Yuan, ancestral home in Shujun Gong..."

"Okay, Wang Yuan, prepare to start construction!"

Wang Hou didn't match the ancient place name he mentioned, so he simply waved his sleeves and turned to the stove again. With this hand, the big blacksmith with a thick face was almost choked to death, with a look of embarrassment on his face, but when he turned around and looked at the blast furnace that was still slightly refreshing in the morning light, fanaticism appeared in his pupils.

The pig iron that was refined was taken out and was put into the blast furnace with a piece of nearly sponge iron. This time, more than twice the roasted large black coal and lime powder as a reducing agent were added. Looking at the full blast furnace, Wang Hou waved his hand with satisfaction, and Wang Ganzi threw another handful of firewood in. Once again, the extremely hot flames began to evaporate.

This time it took a long time to burn. I watched the blacksmiths be busy for two hours here, and it was noon, and Wang Hou's stomach began to roar.

In this era, there was too little oil and water. Wang Hou, who could gain weight by eating cat food in the future, could not get hungry. He left behind the tropics with exhausted sweats. He went back to find a big stove to eat, and did not need too much labor. The tenants who gathered together to watch the fun also dispersed. They should go home to eat, go home to dig coal and continue to change steamed buns, so they dig coal and continue to change steamed buns.

Among the group, the only dedicated person was the blacksmith-headed Wang Yuan, who had muscles on his face. He was working as hard as he was injected with chicken blood. In the winter, he threw his outer robe aside, revealing his strong chest muscles, sweating all over his body, but his copper bell-like leopard eyes were shining, and he was panting and pulling the bellows.

A strong wind blew into the hot furnace, and the coal fires were even swaying. The bricks inside the furnace were even red and seemed to be about to crystallize. After a few more hours, Wang Yuan suddenly shouted and broke a piece of protruding in the middle of the furnace. The hot iron instantly squirted out along the holes left behind, and it was injected into the cement pool dug under the two blast furnaces yesterday.

This is the steel-frying method of this era. Even if Wang Hou is not there, Wang Huizi and Wang Yuan can still do it like fish in water. They are holding a large wooden pole, and they are not afraid of heat and make do with the pool. They stir in the pool regularly every few seconds. Every time they stir, the wooden sticks are burned. After about ten minutes of stirring, the melted iron gradually solidifies, and the originally red surface is densely packed with a layer of scar-scarred impurities like volcanic ash.

Taking advantage of the last few moments when the metal was still soft, Wang Yuan divided the pool into nine grids with a big stick. After waiting for a few minutes, the metal cooled down directly. He did not hesitate to smash the bricks on the edge of the pool and then smashed off the previous layer of impurities. The inside was slightly dark and the ripe iron with a silver luster of metal suddenly appeared. Moreover, some of the iron wrapped in the ripe iron was steel!

Wang Hou was holding a steamed bun and pickled vegetables in his stomach! Suddenly, Wang Yuan was like a madman, holding dozens of kilograms of heavy cooked iron, and rushed in excitedly, throwing the heavy guy to Wang Hou's feet with a bang, shouting with a chorus.

"Master! I've been trained! My ancestors have never seen such excellent iron materials!"

But his excitement almost hit Wang Hou's feet, which scared Wang Hou's mouth was so hot that he choked in his throat, and rolled his eyes so much that his old face turned from yellow to blue. Finally, he simply thrust over to the ground and died of suffocation.

A great time traveler of this generation choked to death by the steamed buns he brought and passed away forever.
Chapter completed!
