What types of rail cast tie plates are there?

Rail cast tie plates are mainly used in track circuits to provide reliable electrical connections to ensure the normal operation of trains. In addition, they are used for the adjustment of track geometry, providing precise track height and level to ensure safe train operation. Rail cast tie plates are mainly divided into the following types:

Punching plate: A punching plate is a pad with holes, which has high strength and stiffness. They are mainly used in track circuits to provide reliable electrical connections. The advantages of punching plates are simple processing, high production efficiency, and suitable for mass production.

Press-in backing plate: A press-in backing plate is a backing plate in which a metal plate is embedded in a rubber pad by pressing. They have good elasticity and insulation properties and are widely used to adjust track geometry. The advantage of the press-fit backing plate is that it has good seismic resistance and can effectively absorb the vibration when the train is running.

Heat-treated backing plate: Heat-treated backing plate refers to the backing plate processed by heat treatment process, which has high hardness and wear resistance. They are mainly used for the adjustment of track geometry, providing precise track height and level. The advantage of heat-treated backing plates is that they have better durability and anti-wear properties, which can effectively extend the service life of the backing plates.

Carbide backing plate: Carbide backing plate refers to a backing plate made of carbide material, which has very high hardness and wear resistance. They are mainly used for the adjustment of track geometry, providing precise track height and level. The advantage of the carbide backing plate is that it has excellent wear resistance and can effectively resist wear.
