Next to the huge blast furnace in Miyun Iron Works, Zhu Houzhao, Zhang Mao, and Xu Guangzuo looked at the blast furnace that was more than ten feet high. They still couldn't believe that they had built such a huge building in just about half a month.
.
"Cement is truly an artifact. Without it, it would have been impossible to build such a large blast furnace in such a short time."
Xu Guangzuo couldn't help but sigh that with cement, infrastructure construction has become much simpler and easier. The huge blast furnace in front of him, which is more than ten feet high and several meters in diameter, was built in half a month.
Of course, during this process, the money Liu Jin spent was just like running water, so many times Zhang Mao couldn't help but feel his eyes turn red and feel extremely distressed. This was all piled up with nothing.
"Fortunately, there is a golden finger, otherwise I would be really confused. I followed the drawings and methods given by the golden finger, and then I built the blast furnace in front of me. I just don't know if it works well. If it doesn't work,
, if we build another one, Zhang Mao would be willing to kill me."
Liu Jin couldn't help but felt happy in his heart. Steelmaking was really a technical job. When making snow and salt, Liu Jin was able to rely on his little knowledge of chemistry. This kind of steelmaking was simply impossible. Fortunately, he had gold.
finger.
The blast furnace in front of him may seem complicated, but in fact the design is quite simple. Of course, this is the conclusion Liu Jin came to after studying the drawings for half a month and personally leading a huge team to build it.
The blast furnace in front of you is mainly divided into five parts. From bottom to top, they are the furnace hearth, furnace belly, furnace waist, furnace body, furnace throat. The furnace hearth part mainly includes the water outlet, slag outlet, blast outlet, hot air pipe, and oxygen.
The input port and the top part of the furnace throat are equipped with various feed inlets and a designed smoke exhaust chimney.
The structure can be said to be quite simple, and there is nothing too complicated. Of course, too complicated things cannot be made in this era. This is also a golden finger simplification, simplification and simplification that can be achieved in this era.
blast furnace.
This is because of the existence of cement. Without the existence of cement, it would have been impossible to build such a huge blast furnace, and it would have been impossible to complete it in such a long time.
"Lao Liu, can we give it a try?"
Zhu Houzhao said to Liu Jin impatiently.
Zhu Houzhao also participated in the entire construction of the blast furnace in front of him. He can now be regarded as a master of blast furnace design. He can learn many places instantly and can even draw inferences from one example, which makes Liu Jin, a person who has traveled through time in later generations, have to
Sigh, we must not underestimate the ancients.
Because he had participated in the entire construction of the blast furnace in front of him, Zhu Houzhao was slightly proud at this time. He seemed to have a sense of accomplishment and wanted to start steelmaking now to test the firepower of this blast furnace.
"Come here in a few days, the ingredients are not ready yet."
Liu Jin thought for a while and shook his head and said, although the blast furnace has been built, steelmaking is not just about having a blast furnace. It requires iron ore, coke, limestone, dolomite, coal and so on.
thing.
Moreover, these raw materials are not meant to be used to make steel as soon as they are mined. They also need to be brushed and sorted. Iron ore, coke, limestone, coal, etc. also need to be crushed. The finer the crushing, the better.
Well, the more complete the chemical reaction can be when burning, the better the quality of the steel produced.
"How many more days have to wait~"
When Zhu Houzhao heard this, he immediately curled his lips unhappy.
"Now we have only built the blast furnace, and our iron ore has just been mined a little bit. The same goes for coal. It is not easy to make steel on a large scale. It requires many steps to be connected.
There can be no mistakes in every aspect.”
Liu Jin smiled and explained.
"Your Highness, let's give it a few more days. Anyway, it will happen very soon."
Zhang Mao smiled and said to Zhu Houzhao.
…
A few days passed by in a flash, and on this day, everyone came to the blast furnace again. Next to the huge blast furnace, hundreds of people were ready to start the first furnace of steel smelting in Miyun Iron Works.
In the huge open space next to it, piles of raw materials have been prepared. The mined iron ore has been crushed. The same goes for coal, coke, limestone, etc., all of which have been crushed into powder and piled aside.
.
"Teacher, everything is ready~"
Huang Jinquan is the director of Miyun Iron Works and is responsible for the daily management and operation of the entire Miyun Iron Works. In the past half month, he has been as busy as a headless fly, but now everything is slowly getting on track.
Everything is in order.
"Well~ let's get started."
Liu Jin nodded and said.
"Light the fire~"
When Huang Jinquan heard this, he immediately turned around and said loudly to the people at the blast furnace.
"Yes~"
Next to the huge blast furnace, a strong man held a torch in his hand. The bottom floor of the blast furnace was filled with coke and coal, and oil was poured on top.
I saw this strong man throwing the torch into the blast furnace, and the inside was instantly filled with raging flames of gas.
"Blow the wind~"
Then Huang Jinquan gave another order. Next to the blast furnace, a huge blower was installed. Dozens of strong men began to pull the winch with great difficulty. As the winch moved, the huge blower began to continuously blow wind into the heating furnace.
, and then through the heating of the heating furnace, the air entering the blast furnace becomes warm air, so that the temperature inside the blast furnace will not be lowered.
"Hu~hu~"
Inside the huge blast furnace, coke and coal began to burn blazingly, accompanied by a steady stream of hot wind blowing, making a whirring sound.
At the top of the blast furnace, the huge chimney began to emit billowing smoke, making this place without any industrial atmosphere begin to be filled with the smoke of the industrial era.
“It’s not cold at all~”
With the burning of coke and coal in the blast furnace, everyone next to the huge blast furnace could clearly feel that the surrounding temperature was rising sharply.
Originally, the temperature was already quite low at this time. It was the winter season, and the dimensions here in Miyun were not low either. The temperature was already below zero.
But now, people who are closer to the blast furnace begin to feel the heat. Some strong men working next to the blast furnace even took off their coats and splayed their arms as if it were summer. Apparently they couldn't stand the heat anymore.
"Start feeding~"
Liu Jin estimated that the temperature inside was already very high. According to the design, the temperature in the center of such a blast furnace can reach 2,300 degrees. At such a high temperature, steel can easily melt.
As Liu Jin's order was issued, the workers at the Miyun Iron Works on site began to take action and built tall brackets around the blast furnace. The brackets were equipped with pulleys. With the pulleys, the workers could easily move a car.
A cart of raw materials rises to the top of the blast furnace, and the raw materials are poured into the feed port.
"Heyyo~Heyyo~"
The scene was very busy, with the workers shouting neat slogans and sweating profusely, as if it was not the coldest month of winter at all, but rather like a scorching summer.
