Chapter 911 Cause of the Accident
After listening to the report of the personal guard, Luo Chong frowned slightly. He stood up and said to You Zhi and Mo Xin, the craftsmen, "You eat first. I have some other things to deal with."
You Zhi, Mo Xin and others hurriedly stood up and bowed to see him off. After Luo Chong left the dining room and came to a corner of the yard with the personal guard, Luo Chong asked, "What happened to the rail experiment? Wasn't it produced well before? How could there be a problem suddenly?"
The guard hurriedly replied, "Reporting to the leader, it's not a problem with the narrow-gauge rail, but a problem with the heavy-load rail, the one that weighs 1 meter and 60 kilograms.
The Xingang County Steel Plant has been After completing the production plan of 10,000 narrow-gauge rails arranged by the leader, the steel bars began to be produced steadily. In order to consume the excess production capacity, the institute tried to produce a batch of heavy-duty rails for actual performance testing, but problems occurred during the test.
They laid a two-kilometer heavy-duty railway on the ramp, and then put a carriage on it, which was filled with a whole carriage of coal. When the brakes were released to let the carriage slide down, less than a mile away, the rails suddenly deformed, the carriage also overturned, and the coal was scattered all over the ground. Fortunately, no one was injured or killed. "The guard reported the message in detail.
Luo Chong frowned even more after hearing it. The previous narrow-gauge railway had undergone the same experiment. When it was used for testing, it was not just one carriage, but fifteen carriages were hung, which were also full of ore. As a result, it ran very smoothly and there was no problem at all.
But now when using the same method to test the heavy-duty rails, a problem suddenly occurred. The rails actually deformed?! Fortunately, there were no casualties.
"What is the reason? Have you found it?" Luo Chong asked again.
"I heard that there was a problem at the joint of two rails. The third joint was bent and flattened, and the front rail was lifted up, and the spikes flew off in a row.
It was the joint between 300 and 400 meters. The section of rails over 300 meters was directly crushed to pieces. The carriage flipped over at an angle, and even several sleepers were broken." The guard answered again.
"Well, when did this happen?" After listening to the specific experimental process and the specific circumstances of the accident, Luo Chong calmed down. The current loss could be completely ignored. He could still afford it, so he was not as panicked as before. "It happened this afternoon
. Someone was sent over there immediately, but it was just a verbal message." The guard answered honestly. "
Then send another verbal message back. Stop the production and experiment of heavy-duty rails first, clean up the accident site first, investigate the cause of the accident, and the steel rolling mill will focus on producing steel bars first. I will make subsequent arrangements when I go there tomorrow." Luo Chong nodded, explained to the guard, and then asked him to deliver the message.
The guard quickly agreed and turned to leave. Luo Chong looked at the sky and saw that it was already completely dark. He simply went back to the backyard of the government office to rest and began to think about the problem.
According to Luo Chong's memory, the steel rails of high-speed railways are generally 500 meters long, so as to avoid joints in the rails as much as possible. However, in the actual laying process, each section of track needs to be welded together, and then polished to make the rails merge into one. In other words, there should be no joints on the train track.
But this was not the case with early steam trains. In the era of steam trains, the rails had joints. Otherwise, why would the train always make a "what's more" sound when it was moving? That was the noise made when the wheels passed over the rail joints.
But as technology improved, people began to pursue quieter and smoother operation, and began to use fusion welding technology to weld rails to eliminate all rail joints. When the rails were first shipped, they were made very long to reduce the cost of welding.
However, this is still a huge problem for the current Han tribe.
How should I put it? The current rail specifications of the Han tribe are all made according to one hundred meters. Even so, it is already very difficult.
Narrow-gauge rails weigh 35 kilograms per meter, and 100 meters is 3,500 kilograms. So if you want to roll such a track, you must first cast a 3,500-kilogram steel ingot, and you must reheat this nearly two-ton ingot to burn it to an orange-red state, soften it, and then use a rolling mill to stretch it.
The heavy load is even heavier, 60 kilograms per meter, and 100 meters is three tons. Then you have to cast a three-ton steel ingot first. Such a heavy thing, and it is still a temperature of thousands of degrees, can only be lifted by pulleys, chains and tracks, otherwise there is no way to transport it. This is just one hundred meters.
If you want to double the length, the rolling mill will not be a problem, but the hoisting machine will be a problem. That is, a six-ton, red-hot steel ingot is not easy to transport. If the length is extended to 500 meters, it will be a 15-ton red iron block, and the difficulty will increase by an order of magnitude.
After thinking about it, Luo Chong couldn't think of a good solution. It is definitely necessary to extend the length of the rail, but it depends on the ability of the research institute. Anyway, it must be extended to 200 meters at least. It is best to come up with a way to weld it. When laying the railway in the future, it will be directly welded into one. This is the best solution.
The next morning, You Zhi first applied to Luo Chong to go back home, and then took his family to live in Takumi County. In the next few years, he will be busy at the construction site in the capital, and it will be inconvenient to be too far away from his family. If he is placed in Takumi County, he can still take time to go back and see.
After picking up his family, he will take his family south and start to gather the manpower of the Jinwu Guard, and then receive the 3,000 slaves that Luo Chong mentioned to go to the construction site.
Mo Xin, the technical team that made the sand table model, will go south later. Once they have finished making the model, they will go with their families to find You Zhi.
Luo Chong agreed to all of them one by one. After sending them away, he finished his breakfast and went to the research institute in Xingang County with his guards to discuss the problem of the rails.
As a result, at two o'clock in the afternoon, when Luo Chong arrived at the scene of the accident under the leadership of Lin Fei, he found that things were not as simple as he had thought before, and the situation seemed to be more serious.
At the joint of the 300-meter experimental track, the rails of the joint were not only bent downwards, but the entire I-shaped load-bearing structure was also twisted. Luo Chong then understood what the guards meant by "flattened" last night.
He pointed to the severely deformed joint and asked Lin Fei, "What do the people in your institute say? This should not only be a problem with the joint. Is there a problem with the steel itself?"
