Q:How do the rails of high-speed railways dock?
Solve the thermal stress of thermal expansion and contraction by the following ways:1, perfect temperature monitoring equipment.2, the manufacturing process to reduce thermal expansion and cold contraction effect. When laying, should also choose the appropriate temperature, so that the minimum value of expansion.3, the tracks are locked on the sleepers so that their stresses are forced to lock. In regions with large temperature differences, regular discharge stresses should also be applied. It is said that the sudden release of the construction site stress, momentum is amazing!
Q:Why not Rail Rail corrosion?
As the train passes, the constant rail friction with the wheel rust away.
Q:How are the rail tracks worn?
Two methods:1, the rails will be melted recast.2. Make rail into other landmark buildings.Note: old rail should be prepared after the public security reported.
Q:Why can't stainless steel be used as rail?
The strength of stainless steel is not reached, not wear-resisting, and the cost is too expensive.
Q:What are the reasons for the development of rail nuclear injury?
Because nuclear damage is produced in the interior of the rail, it is often difficult to detect. Therefore, it has a great hidden danger to the railway transportation safety.
Q:What is the connection of the rail joint?
A part that connects rails or rails and ties. The former is called joint connection parts; the latter is called intermediate connection parts. Its role is to effectively ensure the rail and rail, rail and sleeper between the reliable connection of long-term, continuous rail as soon as possible and integrity, prevent rail relative to the longitudinal movement of the sleeper, ensure the normal track, and give full play to the role of dynamic cushioning performance of vehicles, slow down the line of residual deformation accumulation.
Q:What railway tracks are also live?
The power supply technology is adopted in many cities abroad and in China, with the advantages of beautiful appearance, no visual obstacles of the electric pole and power supply line, and low maintenance cost. The supply rails are usually equipped with protective covers.
Q:How to solve the problem of thermal expansion and cold contraction of railway rail?
In order to solve this problem, the railway department within a certain distance, playing a few holes in the rail waist to release the energy generated by thermal expansion and contraction, and within a certain distance (about 1500m) retaining rail joint, to assist in releasing the energy generated by the thermal expansion and contraction, in order to solve the problem of rail expansion and contraction.
Q:What is the difference between rail welding and field welding of railway rails?
Field welding, usually in the workshop, the first 12.5 meters of track welding, welding into hundreds of meters, or even kilometers long track welding.
Q:What is the material for railway track
The railway tracks are made of steel and can be divided into ordinary manganese containing rails, copper containing plain carbon steel rails, high silicon copper bearing steel rails, copper rails, manganese rails, silicon rails, etc..
