Features
Rail plate
Position and function
The iron plate of the rail is located between the rail and the sleeper, and is a key component of the track structure. It mainly plays the role of damping, buffering and protecting rail and road surface.
Material
The material of the rail iron plate is mainly forged (that is, cast steel) and brass. Forgings have high toughness, strength, corrosion resistance and durability, while brass is used to make fasteners such as bolts and has good corrosion resistance and electrical conductivity.
Function and function
Shock absorbing buffer
The rail cushion plate is set between the concrete rail and the rail, which can absorb the shock and vibration of the wheel and rail effectively, and reduce the fatigue and damage of the rail structure.
Improve stability
The plate can prevent the uneven subsidence and deformation of the contact surface between the rail and the cement concrete, ensure the smooth running of the train and improve the smoothness of the road surface.
Reduce noise and wear
The pad has good sound insulation and vibration reduction performance, which can reduce wheel-rail noise and vibration, and reduce the wear between the wheel tread and the rail.

Application scenario
Main railway lines
Widely used in various railway trunk lines, including passenger lines, freight lines and so on.
High-speed rail
High-speed railways have higher requirements for the performance of the gasket, and usually use specially designed high-performance gasket.
Urban rail transit
It is used in metro, light rail and other urban rail transit systems to improve ride comfort and durability of rail systems.
Installation and maintenance
Installation: In the process of installation, it is necessary to clean the mud on the rail surface of the iron cushion plate, and place the underrail plate on the iron cushion plate rail surface in the correct direction. In addition, pay attention to the installation positions and fastening of accessories such as insulation blocks, T-bolts, and elastic bars.
Maintenance: Regular inspection and maintenance of the pad to ensure that it is intact, no cracks, no deformation and other phenomena. If there is damage or aging, it should be replaced in time to ensure the safe operation of the railway.
