The blower is driven by one large gear and then two pinions, so that the whole blower runs at a higher speed than the speed released by the steam engine. Pen & Fun & Pavilion www.biquge.info

And why the blower uses two pinions is because the blower has two fans, one is the intake fan, and the other is the hole that is conveyed to the blast furnace also needs the blower to act at the same time.

And the difference between the air supply hole of this blast furnace is that after the air supply hole leads to the inside of the blast furnace, it is divided into four lanes to form a cross-shaped branch inside the blast furnace, so as to achieve a uniform supply of oxygen to the blast furnace.

As the ore mixture entered the blast furnace, billowing black smoke had begun to emerge from the blast furnace exhaust hole, the bottom layer of the blast furnace began to react at high temperature, and the middle throat was directly generated.

Because of the first blast furnace, everyone present, no one knew more than Yao Ran, of course, Yao Huo had also asked Yao Ran in detail about these things, these things, and those questions.

Yao Huo moved away from the ventilated spherical valve, and the ceramic pipe trembled slightly because of the gas passing through.

Whether it is a pipe, a gas supply hole, or a tie rod push rod of the transmission device, a transmission shaft, and a transmission rod, they are all fixed in mid-air by some iron or wooden shelves, so that people can see intuitively.

It's not that Yao Ran is for the convenience of teaching, but for the convenience of maintenance, in fact, as long as the person who works in the blast furnace camp can draw the design of the blast furnace camp and the blast furnace after working for a long time, even if the scale and size are wrong, but there is definitely no problem with the principle. Because you can see it all.

But Yao Ran didn't care about them learning, Yao Ran once said to Yao Huo, "I have mastered the knowledge and I have never been afraid of others learning, because it is what I mastered, and then you learned, if I am defeated by the knowledge I have mastered, it can only mean that I am lazy." ”

This sentence has also become a famous saying in later generations, but of course Yao Ran here is insincere, because Yao Ran himself knows that even if you master it, what can you do, because Lao Tzu and I have more science and technology. No matter how you play, you won't lose, and even if you master it, I can just get something out and crush you.

Of course, in front of his students, Yao Ran would not say what was in his heart, and even if Yao Huo knew Yao Ran's heart, he would not pass on these things to slander his teacher's image.

After Yao Huo opened the spherical valve of the gas pipeline, the boiler of the entire steam engine was fed into the gas, charcoal, and oxygen after full combustion, and the flames under the entire boiler became more violent.

Yao Ran hurriedly ordered someone to open the water injection valve and inject the circulating water into it again through warm water. Yao Ran didn't want to come to a dry pot on the first day. The boiler was burned. After all, today I came to open the furnace to make iron, not to burn the furnace to play.

After injecting a large amount of warm water, the pressure gauge of the boiler dropped significantly, but it did not affect the allowable speed too much, because the original operating speed was not very fast.

After four hours of time, the conveyor belt has already injected a ton of raw material into the blast furnace, if calculated according to the proportion of various ores, there is a large amount of coal and a small amount of limestone, and a ton of mixed raw material in the first blast furnace can produce more than 200 kilograms of pig iron.

After Yao Ran's retinal system calculations, the cost ratio of coal is less than 10% higher than that of charcoal, that is, 8 or 9 percent.

In this way, the total amount of ironmaking will be much more than doubled. The amount of iron produced on this road can reach nearly 300 kilograms of pig iron.

Of course, Yao Ran was happy to produce this way, although the retinal system had obtained it before, there was almost no statistics of the difference, but seeing is believing.

Human beings are often happy because they have seen their loved ones, or they have seen something they like. It's the same as the prediction of the retinal system, like, we know that the sun will rise tomorrow, but when we see the morning sun shining, our hearts will still be very happy. It's a truth.

There is another happy thing, it happened when the iron was smelting, when everyone was having dinner, just when Yao Ran was about to eat, Xiao Ping rubbed in front of Yao Ran, and mysteriously handed Yao Ran a thing wrapped in white cotton cloth, Yao Ran opened it and looked at it without seeing what it was.

I didn't want to study it, but Xiaoping reached out and felt a small, shiny yellow irregular piece in his arms. Yao Ran's eyes lit up, "What is this?" I still didn't think about it, Yao Ran directly opened the retinal system to analyze.

The direct answer given by the retinal system is amber. Oh yes, yes, it's just a kind of resin fossil that Yao Ran fried very hot in that era. However, it can also be used as medicine, it can stop bleeding, and it can also be worn to calm the nerves, because amber is a kind of pine resin.

Yao Ran looked at the one in his arms, which was much bigger than the one Xiao Pingping took out. It's the size of a fist of its own, such a big piece of amber.

In the end, it was an era when nature was abundant, and there was a lot of everything. Such a large piece, it is not bad to cut it and give it to a few wives as gifts, but it is a pity to have such a large piece of raw materials.

Xiaoping saw Yao Ran looking at the big light stone in his hand, and he was quite happy in his heart, because his teacher liked it, even if he didn't work in vain.

But Yao Ran doesn't think so, since you kid come to honor me, how can this piece be, give me a big one, there must be a smaller one.

Yao Ran didn't say politely to Xiaoping and said directly, "Sit down and wait to eat together, Yao Huo, you come over too, I'll give you a little knowledge of popular science." ”

Saying that, Yao Ran put the yellow transparent crystal in Xiaoping's hand on the dining table in front of him, these dining tables were all pulled over temporarily, and there were corresponding chairs, and eating outside the open air was just to wait for the first iron to come out. The following activities have not yet been completed.

"This thing, it's called Amber! Do you know how this came to be? This thing is actually the low tree oil on the pine tree, also known as resin, you know, yes, but it's different from what you've seen. ”

Yao Ran was pretending to be mysterious, talking loudly, and the students behind him who were in their seats looked sideways, and some people wanted to come over to see what was going on, but they were all stopped by the guards, just kidding, what did Wei Jin do, he was originally Yao Ran's guard, but he was just the one who would bring Yao Ran safety.

This is even more true now.
