As an overall engineering structure, fish bolt is laid on the roadbed, plays a guiding role in train operation, and directly bears the huge pressure on vehicles and vehicles. Due to the dynamic nature of train operation, each component must have sufficient strength and stability to ensure that the train runs smoothly and uninterrupted at the specified speed.
On the one hand, the rail supports and guides the wheels of the locomotive and vehicle, directly bears the force of the wheel and other forces, and transmits it to the pillow; On the other hand, it provides resistance to the rolling of the wheels, and in the electrified railway or automatic block section, the steel rail also acts as the role of fish bolt circuit. Therefore, in order to achieve this application effect, the rail must have sufficient strength, toughness and wear resistance. The cross-section shape of fish bolt is an I-shape composed of three parts: rail head, rail waist and rail bottom. fish bolt has good force, material saving and denaturation resistance.
