Chapter 329 The Eternal Math Problem
The whole morning passed so quietly, nothing happened.

At noon, the master and the apprentice came down, went to the boiler room to pick up the lunch box, and then carried it to the post to eat.

"Master, is there no water on us? What are you drinking?"

"I didn't bring it. I'll drink it when I'm thirsty. There is one in the operating room. You can bring a water bottle in the future, and just bring it up from below."

"We don't have an electric stove here?"

"Didn't do that stuff."

Zhang Xinglong bent down and looked under the bed: "Master, what is the light bulb under the bed for?"

"It's warming up by the fire in winter, and the bed will be warm when it's lit, so it's good."

"This light bulb is big enough."

"One five hundred watts, very bright."

Before the meal was finished, the phone rang again. It was still Factory [-] and it was time to transfer trains.

Li Hai'er called the operating room to report again.

The telephone here is the internal line of the factory, all four-digit number, pulse, the whole Benxi Steel uses this line, and the factory can be connected with each other.There are external line-controlled telephones only in the workshop and factory.

In fact, this pulse phone can also get through with the municipal program control, but it cannot dial and has to take pictures.

I don’t know which great god discovered it when he was idle. Anyway, most of the workers in the factory can pick up the microphone, jump up on the fork below, and pat the fork with your hands. Continue to the next digit, and you can basically get through in one shot, but the call quality is not very good and the noise is loud.

After finishing the meal, the lunch box was packed away, and the fifth factory changed trains.

Feeling that the whole stone house was shaking, Li Hai said: "Turn around, I'll go and have a look."

Go out to the material pit and walk around, and drive the unloading truck to an empty pit.

The ore unloading car is very large, and it is mounted on the rails. The switch is a paddle. If you push it forward, you will go forward. If you push it backward, you will go backward.

There are three feeding ports, which can feed materials at the same time or separately. Li Haier took Zhang Xinglong and explained it to him.If you feed at the same time, you can supply two mines at one time, the one under the car and the one on the top.

"Don't look at the pit at the bottom, it's full of dead ore on all sides, piled up, just in the middle, the material is turned very fast, so you have to keep an eye on it, and when it's halfway through the pit, you have to replenish the material, and if it's slow, it will leak .”

"What if I missed it?"

"Let's cut the material. It's okay to miss one. I'm afraid that if you miss all of them in time, you will be finished. The next one will definitely report to the next level. Then you don't want the bonus."

"What if it's all full?"

"There are five pits. When four of them are full, you have to call the operation room to stop. Do you understand? The fifth pit will be opened when the pit is half full. Don't wait for it to be full. The parking will be from the beginning to the end. After you call, you will stop." It is expected that it will take a while, if it is full and then stop, this side will pop up."

"What if it comes out?"

"Isn't there a shovel? Take it back and clean it."

Zhang Xinglong turned his head to look at the shovel in the corner and nodded.

"It's good for us. Basically, there is nothing wrong with the spirit. The thieves on the belt road below are tired. A shift must pick up at least a few tons of goods. If the back is light, it will be more than a dozen tons. Some positions have high belts. You have to pick up Throw it up."

"Dozens of tons? Can't you be exhausted? There's no end to it."

"Then the whole team has to do it. It's an accident. There are frequent things down there, several times a month."

Zhang Xinglong thought about it, it was too scary.

Li Hai'er picked up the phone and called the operation room: "Yaosi zero, the fifth factory has been transferred, four pits."

Not long after putting down the phone, a piercing scream sounded in the factory building, a bit like an air defense siren, and then the whole factory building shook violently, a puff of dust burst out, and the belt started to rotate.

The entire workshop space was filled with rumbling sounds.

After turning for a while, about ten minutes or so, the ore began to come up on the belt, a little at first, and then more and more, gradually covering the belt, and poured into the material along the mouth of the ore unloading car. pit.

The sound was like rainstorm.

Li Hai'er closed the resting iron door: "Wear a mask when you go out, even though the dust is small, it's not good to absorb too much."

Zhang Xinglong nodded, and took the Zhu Bajie mask that was placed on the iron table.

"We don't need to wear this here, it's too stuffy, just use this kind of non-woven fabric, and change it in a few days." Li Haier came to teach Zhang Xinglong to change the filter paper filter cloth. Used on the air port in the middle.

"What's the tip down there for?"

"Water came out. After covering this for a while, it was full of dripping water and sweat."

Zhang Xinglong nodded, understood.There is heat in the panting, and water droplets will form on the inner wall of the mask, which will flow out along the sharp mouth below.

"The filter paper has to be changed frequently, otherwise it will be useless. The equipment in the factory below can't see people on the opposite side. If you don't have this for a few days, you will get silicosis, which is like suicide."

"Isn't there dust removal equipment?"

"That's useless. It doesn't turn normally, that is, those who come from above to check things turn around for a while, and they can't turn."

"Why? Isn't there no dust when you turn it?"

"The water sprayer, the belt is full of water when it turns, the ore is stuck to the belt, and the sticky shovel is hard to shovel, so the job can't be done. Then there is no need to do other things, it is everywhere Thin mud, the belt will slip and hold down after a while. Are you still in production?"

Zhang Xinglong scratched his ears, but he couldn't imagine what it was like, he had only seen the two strings of [-] until now.

"It's full." Li Hai opened the door and ran out, Zhang Xinglong followed behind: "How do you know?"

"Listen." Li Hai ran over to start the unloading truck and walked forward. The ore in the mouth was pulled out to two planes, and then it reached the empty pit and flowed down with a splash.

"It is full of ore piled in the mouth of the mouth. It is made of iron and crackling. If the pit is not replaced in time, it will come out along here." He pointed to an iron cover on the mouth of the mouth: "This is If the ore is alive, it will be opened as soon as the ore comes up."

This is really a test of experience and speed, Zhang Xinglong estimated that from hearing the abnormal noise to the mouth full of water, it took at most one or two minutes.

Li Hai climbed onto the unloading truck and opened the partition in the middle, and the ore split out and went to the No. [-] pit at the front along with the belt.

"Don't drive the car to the end, that's what pit No. [-] over there is, just keep an eye on it."

"why?"

"Why give it to you like this? Isn't it good to give two pits at once? It's not easy to miss. The eighth pit is just like this, and you can take a look at it after a while. These pits are given back and forth here. Just keep the information. gone."

"When will it be filled?"

"If there is enough material, it will take two hours. If it can be full in two or three hours, then we will call and stop the car. Our loading is faster than that of the bottom."

Zhang Xinglong immediately thought of the math problem that always existed on the test paper, and asked how long it would take to fill it up.

Damn, didn't the person who made the question work in ore crushing?
