(New Year to the grassroots) fighting behind the Spring Festival "welding rail people"
China News Network Chengdu, January 19 Title: "Welding Rail People" Fighting Behind the Scenes of the Spring Festival
Author Wang Meiyi Wang Peng
When people think of the Spring Festival, the first thing that comes to mind is the weaving flow of people and the speeding train. However, there is also a group of "welding rail people", who insist on staying behind the scenes of the Spring Festival to ensure the safety of railway rails.
On the 19th, china railway Chengdu Bureau Group Co., Ltd. Chengdu engineering overhaul section of the stone slab beach welding rail base rumbled, everywhere can see a busy scene. During the Spring Festival, in order to ensure that more lines can be staggered and opened for operation, the Shibantan welded rail base, as the only long-track production and supply base in the southwest region (Sichuan, Chongqing and Qian), the amount of production tasks has soared compared with usual.
"Once upon a time, the sound of 'beeping' was synonymous with trains." Ran Hongjiang, foreman of the Shibantan welding rail base, said that the traditional railway line uses 25 meters of steel rail, which is connected by a joint splint, and when the train passes through the joint, it will produce a shock vibration, which will emit a sound of "beeping dangdang", which not only limits the speed of the train, affects the comfort of everyone's ride, but also increases the line disease.

In recent years, with the popularity of high-speed rail, the public's travel has become more convenient, and the smooth and rapid operation of high-speed rail has even achieved the scene of "the coin stands for 8 minutes". Behind this phenomenon, there is the credit of "welding rail people".
Ran Hongjiang said that now that seamless lines have been popularized, it eliminates the line rail joints, improves the strength of the track structure, optimizes the driving conditions, and the sound of "clanging" disappears. "As an important part of the seamless line, the long rail welded joint will directly affect the quality of the line and the safety of driving, and the long rail is achieved by the weld rail base in the use of fixed flash welding."
Walking into the Shibantan welding rail base, the huge yellow welding machine welding flower overflowed, welding 100 meters of rail into a 500-meter long steel rail. Welding needs to go through more than a dozen processes such as rail selection, rust removal, welding, rough milling, heat treatment, fine straightening, fine grinding, appearance inspection, flaw detection, etc., to ensure the high-quality use of long rails after welding.
Ran Hongjiang stared closely at the welding machine, afraid of missing any detail, he observed the inside of the welding machine and the state of the rail weld from time to time to ensure the quality of the welding.
"I am in a key position here, I dare not be sloppy at all, just like the foundation of a building, only if the foundation is laid firmly, the building can be safe and stable." Ran Hongjiang said.
In the 500-meter track yard, Huang Xiao, director of the workshop, is organizing the loading of long steel rails, only to see the group crane device hoisting a 500-meter long rail to the long rail car, the scene is very spectacular, and the hoisted long rails will be sent to the track laying site of each new line.

Up to now, the Shibantan welded rail base has successively supplied rail beijing-Shanghai high-speed railway, Chengdu-Chongqing intercity, West Chengke special, Chenggui high-speed railway, Chenglan railway, Chengkun complex line (Emi section), Zhengwan high-speed railway, Sichuan south intercity, Chongqing East Ring Line, Guiyang Southwest Ring Road and other lines.
"Although we 'welding rail people' are silently paying behind the scenes of the Spring Festival stage, we are full of pride when we watch the 'Fuxing' galloping on the vast land of the motherland and constantly refreshing China's speed." Huang Xiao said affectionately that although the "welding rail people" are usually bitter and tired, everything is worth it compared with ensuring the safe travel of passengers. (End)
