Of course, the blast furnace is not lit with a twist or a match, or a lighter. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info Instead, the burning coal is poured directly into the blast furnace.

Coal, a fossil formed after tens of millions of years of qualitative change, has the characteristic of releasing high heat, which is higher than the heat released by Yao Ran and the charcoal they burned in an earthen kiln.

Only in this way can the higher heat provide more heat for the entire blast furnace ironmaking process, and the furnace temperature can be quickly melted away by increasing the furnace temperature.

So if you want to light the blast furnace in front of you now, you actually have to use coal to ignite it. By the time everyone arrived, a pile of burning coal had been piled up on a cart opposite Yao Ran. A few shovels were also set aside.

And Yao Ran, Xiaoping, Yao Huo, Xia Zhi, Wei Jin and others have all stood in front of this new blast furnace, several people are facing everyone, these individuals in the audience, whether it is children, or teachers who came to Yao Zhai for further study, even the soldiers who finish the steam engine and do not let people get too close, these people's eyes are attracted by Yao Ran's exhale.

Yao Ran stretched out his hand and pressed it down, but there was no applause, and slowly everyone's attention was dragged back to Yao Ran, Yao Ran finally spoke after waiting for a few minutes,

"Today is our second blast furnace, the day of the ignition furnace that was built, don't tell me that you don't know what a blast furnace is, you don't know how to make iron, you can ask why iron is the main metal material. Why can't it be other metals. You can also say that iron is not hard enough and not tough. ”

Yao Ran said that all people's attention was focused on Yao Ran, because of these questions, some people may have thought of it, and some people really didn't think of anything. And listening to Yao Ran's speech before, I did have it once in the auditorium of the family college.

But I didn't see such a large device in person today, and it was a pleasure to watch the idols of the whole family give speeches like this in the sun.

"Yao Ran continued to speak, I will tell you here today, the blast furnace was built for you to see, and the ignition of the blast furnace is not for you to visit, but to let you be interested in such technology,"

"In the future, you will be able to make more and better materials and utensils for your family and yourself. So that our families, the people we love, can live a more comfortable life and live a safer life. ”

"Because we have an iron ballista and an iron spear and a long knife, we killed the Canglong who ate our relatives in Canglong City, because we have an alpaca cart and a fishing net, so everyone in our family, including those strongholds where there is no river passing by, can also eat fresh big fat fish."

Yao Ran said that he was very selfless, in fact, to let these people come is to let the people present understand the importance and danger of working here, but nearly one-third of them must stay here and start working immediately.

And Yao Ran was indeed forced to have no way and didn't know where he should find someone to fill these vacancies, maybe Canglong City really had a lot of idle population, but would Wei Mu let them be idle? The answer, of course, is no.

And Yao Ran also needs more people to work for himself, whether it is iron mines, coal mines, transportation, or places like blast furnace camps, to participate, and now it is obvious that Yao Ran's intention is to let these people receive more education before they want those who have learned advanced knowledge to participate in the work.

However, in the case of shortage of manpower, Yao Ran had to interrupt the studies of some people first, and not a small part, but a large part of the people may have to participate in the work of various places.

After Yao Ran finished speaking fluently for more than ten minutes, Yao Ran finally shouted, "Prepare to ignite!" ”

The two workers put the burning coal on the position of the entire blast furnace taphole, and when the waiting people were in front of Yao Ran, Yao Ran opened his mouth and said, Come on, pry one person and one pry together, let us witness together.

After several people said yes in turn, they picked up the sled standing on the ground, and almost everyone had one hand, and Yao Ran and Yao Huo were the first, and the two of them, facing the heat wave on their faces, came out in the trolley.

But as the coal in the shovel was put into the furnace, a spark on the coal was blown out by the blower in an instant, and the crackling sound made the whole boiler instantly resound, and there was a subtle echo.

The louder sound was the sound of the wind spewing out of the tuyere, whistling continuously. Then it was the summer solstice, and Xiaoping and Xiaoping added coal to the furnace, and then Wei Jin, and Wei Shui, after several people finished it at once. Even if this ignition ceremony is completed.

Then Yao Ran walked to the position where he came, and there were already several workers waiting in front of the conveyor belt, and the ore that had been crushed and mixed was mixed with crushed crushed powder less than a meter above the ground.

The conveyor belt is almost attached to the ground, and at an inclined angle of 80 degrees, the raw material of the ore is transported to the position of the furnace mouth for ironmaking.

After entering the blast furnace, the powder will begin to melt, and finally the molten iron melted at a temperature of up to 1,000 degrees will flow out of the taphole, and then be packed in containers and delivered to every place where they are needed.

The switch handle of the transmission belt is on the left side of the conveyor belt. Since there is no research on electronic switches, it is impossible to simply control them on a single controller.

Only this can actually be used by the gear transmission a push-pull plug-slip to push the transmission rod to the position of a crankshaft on the steam engine, when the gear rotates clockwise, push-pull plug-slip will, the transmission rod is pushed to the bending part of the crankshaft, so that the purpose of the eccentric gear rotation of the conveyor belt is driven by the displacement of the bending position of the crankshaft, so as to drive the whole conveyor belt to start running.

When closing, the gear is rotated counterclockwise, and the push-pull plug slides to push the transmission rod back to the non-rotating position of the crankshaft, so as to achieve the purpose of stopping the cup.

These devices and power transmission devices all used a large number of iron tools, with only a few cotton separators and some wood used as some supports.

When Yao Ran began to turn the switch, not to mention that it was quite laborious, it took more than ten seconds to push the transmission rod to the position, and then the entire conveyor belt began to run at a uniform speed.

In fact, the whole steam engine is still running very fast, but because the transmission of each position requires different speeds, the steam engine drives a huge cylindrical gear, and the different gears that are engaged with the gears in different positions begin to be large and small. Like a conveyor belt, it's a big gear that's being driven.
