The rail is the main component of railway track. Its function is to guide the wheels of the locomotive, bear the great pressure of the wheel, and pass it on to the sleeper. The rail must provide continuity, smoothness and resistance to the wheel. In electrified railway or automatic block section, rail can also be used as an orbital circuit.

Constitute: railway track

Function: guide the wheels of the locomotive

Bear: the great pressure of the wheel

Provide: continuous, smooth and resistance minimum rolling surface

Kind: qu70, qu80, qu100, qu120

The strength, wear resistance and resistance to impact of rail, depend on the material of the rail, it depends on the chemical composition, metallographic structure, production process and heat treatment quality of the steel. In addition to iron, the steel rail contains carbon, manganese, silicon, sulfur and phosphorus. High carbon content can increase the strength of steel rail, but high carbon content will reduce its plasticity and impact toughness. Appropriately increasing the content of manganese and silicon can increase the strength, hardness and toughness of the rail. Sulfur and phosphorus are harmful impurities that do not permit exceeding the prescribed limits. In addition, adding the appropriate amount of chromium, nickel, molybdenum, vanadium, titanium or copper to the steel rail to make alloy steel rail can improve the quality of the rail.
