Miyun Iron Factory, next to the huge blast furnace, Zhu Houzhao, Zhang Mao, and Xu Guangzuo looked at the blast furnace that was more than ten zhang high, and it was still hard to believe that in just half a month or so, they had built such a huge building.

"Cement is worthy of being an artifact, without it, it would be impossible to build such a large blast furnace in such a short time."

Xu Guangzuo couldn't help but sigh, with cement, it has become much simpler and easier to build infrastructure, and the huge blast furnace in front of him is more than ten zhang high and several meters in diameter, and it was built in half a month.

Of course, in this process, the silver that Liu Jin spent was like flowing water, so that Zhang Mao couldn't help but reddened his eyes many times, and his heart was extremely distressed.

"Fortunately, there is a golden finger, otherwise it is really black, and the drawings and methods given by the golden finger are drawn in the same way, which creates the blast furnace in front of me, but I don't know if it is good or not, if it is not easy to use, and then build a new one, Zhang Mao killed my heart."

Liu Jin couldn't help but rejoice in his heart, steelmaking is really a technical job, and when he made snow salt, Liu Jin was able to rely on his half-understood chemical knowledge to achieve it, and this steelmaking was simply impossible, fortunately, there was a golden finger.

The blast furnace in front of him seems to be very complicated, but in fact, the design is quite simple, of course, this is also the conclusion that Liu Jin came to after studying the drawings for half a month and personally building it with a huge team.

The blast furnace in front of you is mainly divided into five parts, from bottom to top is the furnace cylinder, furnace belly, furnace waist, furnace body, furnace throat, the furnace part is mainly the water outlet, slag outlet, air outlet, hot air pipe, oxygen inlet, and the top part of the furnace throat is set up with a variety of inlet inlets, as well as the design of the smoke exhaust chimney.

The structure can be said to be quite simple, and there is nothing too complicated, of course, things that are too complicated, and this era cannot be done at all, which is also a blast furnace that can be realized in this era after simplifying, simplifying and simplifying.

This is also because of the presence of cement, without which it would have been impossible to build such a huge blast furnace, and it would have been impossible to build it in so much time.

"Lao Liu, can we give it a try?"

Zhu Houzhao said to Liu Jin a little impatiently.

In front of this blast furnace, Zhu Houzhao also participated in the whole process of construction, he can now be regarded as a master of blast furnace design, in many places, he can learn it, and even be able to draw inferences, so that Liu Jin, a person who has crossed over in later generations, has to sigh, and must not underestimate the ancients.

Because he participated in the construction of the blast furnace in front of him throughout the whole process, Zhu Houzhao was also slightly proud at this time, and seemed to have a sense of accomplishment, eager to start steelmaking now and try the firepower of this blast furnace.

"Come on 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 needs iron ore, coke, limestone, dolomite, coal and other things.

And these raw materials are not said to be able to be used for steelmaking immediately after mining, but also need to be brushed, iron ore, coke, limestone, coal, etc. also need to be crushed, the finer the crushing, the better, the more sufficient the combustion chemical reaction, the better the quality of the steel.

"I'll have to wait a few days~"

When Zhu Houzhao heard this, he immediately pouted unhappily.

"Now we have only built a blast furnace, our iron ore has just been mined a little bit back, this coal is also, it is not easy to make steel on a large scale, it needs many steps to be connected, and every link can not go wrong."

Liu Jin smiled and explained.

"Your Highness, let's have a few more days, it's a matter of time anyway."

Zhang Mao said to Zhu Houzhao with a smile.

……

A few days passed in a flash, and on this day, everyone came to the blast furnace again, next to the huge blast furnace, hundreds of people were already waiting for the first furnace of steel in Miyun Iron Factory.

On the huge clearing next to it, piles of raw materials have been prepared, and the iron ore has been crushed, as have coal, coke, limestone, etc., all crushed into powder and piled aside.

"Teacher~Everything is ready~"

Huang Jinquan is the director of Miyun Iron Plant, responsible for the daily management and operation of the entire Miyun Iron Plant, this half a month, he is busy like a headless fly, but now everything is slowly going to be normal, everything is in order.

"Hmm~ Let's get started."

Liu Jin nodded and said.

"Ignition~"

When Huang Jinquan heard this, he immediately turned around and said loudly to the people on the side of the blast furnace.

"Yes~"

Next to the huge blast furnace, a strong man held a torch in his hand, and the bottom of the blast furnace was already filled with coke, coal, and oil.

I saw this strong man throw the torch into the blast furnace, and the gas in it was instantly blazing.

"Blower~"

Then Huang Jinquan gave another order, next to the blast furnace, a huge blower, dozens of strong men began to pull the winch hard, with the winch twisting, the huge blower began to blow into the heating furnace in a steady stream, and then through the heating of the furnace, the wind into the blast furnace is the warm air, so that the temperature in the blast furnace will not be reduced.

"Whew~Whew~"

Inside the huge blast furnace, coke and coal began to burn brightly, accompanied by a steady stream of hot wind, and there was a whirring sound.

At the top of the blast furnace, huge chimneys began to billowing smoke, filling this place with the smoke of the industrial age.

"It's not cold at all~"

With the coke and coal burning in the blast furnace, next to the huge blast furnace, everyone could clearly feel the temperature around them rise sharply.

Originally, the temperature was already quite low at this time, it was the winter season, and the dimension of Miyun was not low, and the temperature was already below zero.

But now, the people who are getting closer to the blast furnace are beginning to feel the heat, and some of the strong men working next to the blast furnace have even taken off their coats, as if in summer, and they are walking around, obviously unable to stand the heat.

"Start feeding~"

According to the design, the temperature in the center of such a blast furnace can reach 2300 degrees, and at such a high temperature, the steel can be easily melted.

With Liu Jin's order, the workers of the Miyun Iron Works on the site began to take action, building a high bracket around the blast furnace, and the bracket was followed by pulleys, relying on the pulleys, the workers could easily lift a car and a car of raw materials to the top of the blast furnace, and pour the raw materials into the feed port.

"Hey~hey~"

The scene was busy, the workers shouted neatly, and they were sweating profusely, as if it was not a cold winter at all, but like a hot summer.
