Chapter 1026 Lin Fei is a gun fan

After lunch, Luo Chong took them to visit the research institute. Lin Fei went to explain the assembly of the tractor because of Luo Chong's order. After a while, he met up with Luo Chong and his group. When they came to the driving class's practice field, Lu Guangzhu, You Fu and She Xin couldn't help but marvel at it. It was the first time for them to see a tractor.

"This thing is called a tractor. Why did the leader give it such a strange name?" Lu Guangzhu couldn't help but ask curiously when he saw the students in the driving class operating the tractor to plow the land.

"Because the tractor itself has no function, its only function is to provide power, just like the front of a train, it replaces cattle and horses and plays the role of traction and traction.

"If you hang a bucket at the back, then it is a truck. If you hang a plowshare, then it can be used to plow the land and sow. If you want it to play a role, you have to see what is hung at the back." Luo Chong explained to them.

"I see, if that's the case, then the name tractor is really suitable. "Lu Guangzhu said with sudden realization.

"Since it is to replace cattle and horses, why not call it Iron Ox? Isn't it more vivid?" You Fu smiled and suggested.

"Haha, the name Iron Ox is good, but it has been used by the leader. Our steam engine has a model called Iron Ox and Iron Horse." Lin Fei also explained on the side. Luo

Chong was watching the students in the driving class training, so he asked a young man who was roasting a fire next to him and waiting for his shift to study.

"How is your driving class learning? Is this tractor easy to learn? How long can you drive it every day?"

"Hello, leader, nice to meet you all."

The young man was nervous when he saw a group of big men surrounding the leader. He bowed to Luo Chong with some excitement, and then said.

"To reply to the leader, this tractor is easy to learn. There are only a few joysticks. You can tell it where to go and just pull the joystick. It's very convenient. It's just that there are too few cars now. I can only drive it for half an hour a day, and I can only drive it once every few days. "

Well, then study hard. You are the first batch of tractor drivers in the tribe. Your future is limitless. If you learn this skill well, you can start a family in two years. By then, you can choose the girls!" Luo Chong patted the boy on the shoulder and encouraged him.

When the boy heard Luo Chong talking about getting married, his face turned red with embarrassment. He smiled embarrassedly and said, "Thank you, chief."

Luo Chong asked a few more students. Everyone's situation was similar, but he knew that when he asked people to form a driving class, he set a quota of 60 people, but there were only a dozen here, so Luo Chong asked Lin Fei.

"I remember that when we formed the driving class, the quota was 60 people. Where did the others go?"

"Replying to the chief, we only have one car now, and each person practices for half an hour every day. The rest of the people can only stay here idle, so I organized them to help in the production workshop, so that they can learn the working principle and manufacturing process of the tractor by the way. When they use it in the future, if there is any minor problem, they can find the problem and repair it by themselves. "Lin Fei replied immediately.

Luo Chong nodded. There was nothing wrong with this arrangement. It was good to let them learn, but the training progress was indeed a bit slow, so he said.

"This arrangement is not impossible, but the training progress is too slow. It must be changed. I'll tell you a few arrangements, please write them down.

"First, starting today, increase night operation training, and don't stop training at night. When they actually work in the spring, there will also be night shifts. Let them adapt to night operations now.

"Second, you can take out the loader and let them drive it. Although it is not a tractor and cannot be used for plowing and sowing, the mechanical principles are the same. No matter what you drive, let them drive it first. In this way, even if they come back to learn the tractor, they can go faster.

"Third, assemble a batch of tractors as soon as possible, and let them drive for at least one or two hours a day before they start working, including daytime driving, field operations, agricultural machinery operation, and night driving. Everyone must meet the standards for these subjects."

"Yes, I'll arrange it right

away." Lin Fei thought about it and felt that there was no problem, so he immediately agreed. Then he said a few words to the people around him and immediately asked someone to get the loader over and arrange a group of trainees to come for training.

Luo Chong discussed the matters of driving class training with Lin Fei here, and Dali also led the three people to the tractor to watch. They also stood on the escalator outside the tractor cab and watched the operation of the people inside, which was very fresh.

Several people wanted to go up and drive, but there were few cars now and the trainees had a heavy training task, so they had to give up.

After a while, another big thing drove out of the factory. It looked very similar to the tractor, but it was a little bigger. The more obvious difference was that the steam engine of this big thing was located behind the cab, and there was a chimney on the side that opened outward. The mechanical device used for work was installed in the front, which was a huge steel bucket.

"Chief, what is this?" You Fu ran over immediately after seeing this big thing.

"This is also a sub-project of this year's project. It is called a loader. Do you see the bucket in front? It is used to load things. Soil, river sand, coal, ore, grain, all bulk items can be scooped up with this bucket, and then lifted up with a mechanical arm and loaded onto a truck. It can also be used to level the ground. Just lower the bucket and then push it flat, so it can also be called a bulldozer." Luo Chong introduced it to him.

"So this is what the leader was talking about. The thing used for road construction is this. If we have this thing, then we can build roads really quickly. Such a big thing will require so much manpower." You Fu immediately remembered what Luo Chong told him yesterday about the machinery used for construction.

"Brother You may not know that there are more than just loaders in engineering construction." Lin Fei said proudly.

"Oh? What other good things are there?" You Fu, Lu Guangzhu, and She Xin were also interested.

"There are also excavators and oscillating rollers. The excavator is used to dig things. It can be used to dig ditches, mine ore and earthwork. It is used in both engineering and mining. The last oscillating roller has a single function. It can only be used to roll the road surface, level and compact the land. It is a good hand for road construction. With this thing, pottery rollers and stone rollers can be completely eliminated." Lin Fei also introduced it immediately.

"Really? Where is it? Let us see it?" You Fu asked immediately after hearing this. If there are these machines, construction projects will be really easy, and it can also save a lot of manpower and horses.

"Of course, but those two machines are not yet completed and have not been finalized. I can't show you now." Lin Fei nodded, and then led them to the workshop.

The group followed him after hearing what he said. Luo Chong also followed behind. He didn't know how the development progress of the two vehicles was.

When the group entered the workshop, they found that more than half of the huge workshop was busy. Now all the machine tools and workers in the workshop were busy to complete the tractor order. The excavator and roller in the corner could only stop working and collect dust there. However, judging from the appearance, the completion rate of these two big guys is very close to complete.

Although the cab has not been installed yet, the main body has been completed.

When they arrived in front of the machine, they recognized which one was an excavator and which one was a roller without anyone introducing it, because the characteristics were very obvious. One had steel rollers in front and behind, and the other had a huge mechanical arm installed in front. There was also an iron bucket at the front of the mechanical arm. You could tell what it was used for at a glance.

"This excavator is good. How much soil can be dug with this bucket? It's much faster than manual digging. When I came back, I heard that the construction site in the capital was still digging soil to lay the foundation. If there was this thing, it would have been laid long ago." You Fu said with emotion while stroking the huge mechanical arm.

"That's right, but why are there two steel soft belts instead of rubber wheels on this excavator?" She Xin asked curiously.

"This is the idea of ​​the leader. The leader said that most of the places where excavators are needed are unbuilt construction sites or mines. The terrain is complex, and some don't even have roads. The passability of rubber tires is not high, and it is not as convenient and safe as this crawler track." Lin Fei immediately explained.

"Yeah, that's right, it's true. The leader is still thinking far ahead." Lu Guangzhu also nodded in agreement.

Luo Chong ignored their flattery and pointed at the bucket of the excavator and said to You Fu and She Xin: "See this bucket? This thing can be removed from this joint. Remove the bucket, replace it with a large air hammer, and install an air compressor on the engine at the back. It can be used to dig tunnels or break rocks. According to the length of this mechanical arm, it is no problem to dig a tunnel of six or seven meters high."

You Fu suddenly realized that the tool used for digging tunnels that the leader mentioned yesterday was this. If this thing was used to dig tunnels, the progress of the project would indeed be much faster. With the help of the tunnel boring machine and explosives, he was confident that he could open the railway to the Tang tribe in a very short time.

"Digging a tunnel? What is a tunnel?" Dali and Lin Fei, who were following beside him, were a little confused. They didn't know what they were talking about. They had not been informed of the situation in the south for the time being. After all, it was something that was just confirmed yesterday.

"We just discussed yesterday about building a railway, the railway in the south. We want to build a railway from the middle and lower reaches of the Liuyang River to the Tang tribe. This section of the railway starts from the plain beside the river, crosses two tributaries of the Liuyang River in the middle, then turns south, crosses a mountain range, and crosses some canyons. The total length of the line is about 600 kilometers.

"If we don't build it this way, we have to take a long detour, and the length may increase to about 900 kilometers. So in order to cross that mountain range, I plan to dig a tunnel directly on the mountain, dig out a cave with ventilation at both ends, and let the train pass through it, which can reduce a lot of distance. "Luo Chong explained to them after hearing this.

Lin Fei and Dali also opened their mouths in surprise after hearing this. Just like You Fu and She Xin's reaction yesterday, Lu Guangzhu was also very surprised. He thought that the leader's idea was too crazy. He actually wanted to dig through the mountain. How could this not be shocking.

"Drill through the mountain and dig a tunnel? This, this is possible? The amount of work is too large! "Lin Fei said in surprise.

Dali quickly laughed after being surprised and said, "I don't think it's a big deal. If it doesn't work, we can use explosives. The leader has done a lot of things like blowing up mountains. When our Han tribe first mined salt mines, it was the leader who used explosives to blow them up. Now we are mining iron ore in Xingang County, don't we also use explosives from time to time?"

After being surprised, Lin Fei heard what Dali said, and he also thought of this, so he continued, "So the leader wants to convert the excavator into a machine for drilling rocks? However, the method the leader just mentioned is indeed not difficult. It's just changing to a large air hammer, but the chisel of the air hammer is not easy to get. We processed a batch of them for the bridge construction site in Qiongzhou the other day. I heard that their air hammers are very expensive and they have to be replaced with new ones after a short time. "

Luo Chong nodded and said, "This depends on you. Didn't I tell you about the task of making the molybdenum steel? You have to make it as soon as possible. This is a high-hardness, high-temperature-resistant alloy steel. With this, the service life of those steel consumables can be increased. You must pay attention to this project."

"It turns out that molybdenum steel is also high-hardness and high-temperature-resistant. That's really important." Dali said in surprise.

"Chief, is it true? Is that molybdenum steel really that good? How does it compare to carbon steel? "

Unlike Dali's reaction, Lin Fei seemed very excited. He knew the actual service life of those rifles in the Han tribe. It was because there was no high-hardness and high-temperature resistant metal material that the rifles designed by Luo Chong became disabled. They would be scrapped after not much use. The good weapons became consumables.

"It's true. According to my estimation, the heat resistance of molybdenum steel is at least three-fifths higher than that of carbon steel. If the melting point of carbon steel is 1,600 degrees, then the melting point of molybdenum steel is at least 2,600 degrees. As for the hardness, it must be very high, but I don't know how high it is. It depends on your experiments. "Luo Chong just lied and said what he knew as his guess, but what he said was all true.

When Lin Fei heard what Luo Chong said, he immediately became excited. As the actual person in charge of the production of the musket, this guy is actually a staunch gun fan.
