Steel Rails Common Sense

We know that the steel rails are mainly used on some steel railroad tracks or guide rails of some special vehicles. Its use is very important for us. Here are some common knowledge about the steel rails!

Steel Rails model (1) Light rails model, rail material: Q235, 55Q; rail specifications: 30kg/m, 24kg/m, 22kg/m, 18kg/m, 15kg/m, 12 kg/m, 8 kg/m;

(2) Heavy-duty rail model, rail material: 45MN, 71MN; rail specifications: 50kg/m, 43kg/m, 38kg/m, 33kg/m;

3) Lifting rail model, rail material: U71MN, U75V; rail specifications: QU70kg/m, QU80kg/m, QU100kg/m, QU120kg/m.

Rails can be divided into: light rail, heavy rail, lifting rail according to their weight, cross-section shape and use:

Less than or equal to 30kg is a light rail. The quality requirements of light rails are low, and only the chemical composition, tensile strength, hardness and drop weight test are required. Main use: Light rail is mainly used for laying temporary transportation lines and light locomotive lines in forest areas, mining areas, factories and construction sites.

Heavy rail: used to lay railways, to withstand the pressure, impact load and friction during train operation, requires sufficient strength and certain toughness, strict quality requirements, in addition to ensuring its chemical composition, it also requires inspection of mechanical properties, drop hammer Test and acid soaking of low-fold tissue, etc. The production plants include WISCO, Anshan Iron and Steel, Baotou Steel and Panzhihua Iron and Steel.

Crane rail: the crane rail, its height is low, the head width and waist thickness are large, only the chemical composition and tensile strength are required to be used for laying cranes larger than and trolley tracks. The production plants are Anshan Iron and Steel and Panzhihua Iron and Steel.
