Steel Trackis the main components of railway track. Its function is to guide the wheels of the rolling stock to advance, to withstand the tremendous pressure of the wheelsand to pass to the sleepers. Steel tracksmust provide a continuous, smooth and resistant rolling surface for the wheel. In an electrified railway or automatic occlusion section, steel trackcan also serve as a track circuit.

　　The classificationof Steel Track:

　　China'ssteel trackscan be divided intoCrane Rail,Heavy Steel RailandLight Steel Rail.

　　1.Crane Rail

　　The crane rail is divided into four types: QU120, QU100, QU80, QU70. The material is generally manganese steel. The single weight is QU120 up to 118kg/m.

　　2.Heavy Steel Rail

　　According to the steel grades used: ordinary manganese-containing rails, copper-containing carbon steel rails, high-silicon copper-containing steel rails, copper rails, manganese rails, silicon rails, etc. There are three main types: 38, 43, and 50kg. In addition, there are 45kg rails for a few lines, and 60kg rails are planned for use on lines with high traffic and high speed. GB2585-81 stipulates the technical conditions of 38~50kg/m rail in China.

　　3.Light Steel Rail

　　The quality requirements of light steel rail are low, and only the chemical composition, tensile strength, hardness and drop weight test are required. Its’main use: Light Steel Rail is mainly used for laying temporary transportation lines and light locomotive lines in forest areas, mining areas, factories and construction sites.
