1.Train wheels are made of killed steel smelted in open-hearth furnaces, electric furnaces or converters.
2.The chemical composition is generally a carbon content of 0.55-0.65. The wheel steel code used by MaSteel is called CL60, which means that the carbon content is about 0.6%. There are also small amounts of silicon, 3.manganese and other elements. Generally speaking, wheel steel is high carbon steel.
If the carbon content is low and the hardness is insufficient, the train wheels will wear very quickly.
Diesel locomotives 1050mm;
electric locomotives 1250mm,
passenger cars 910mm;
freight cars 840mm.
High-speed test wheel diameter 915 mm
The structures, shapes, sizes, and materials of wheels are diverse.
According to its use, it can be divided into passenger car, truck and locomotive wheels. According to its structure, it can be divided into integral wheel and tire wheel.
Tire wheels can be divided into cast steel spoke wheel cores, rolled steel spoke wheel cores and cast steel spoke wheel cores.
Integral wheels can be divided into rolled steel wheels, cast steel wheels, etc. according to their materials.
In order to reduce noise and unsprung mass, new wheels such as elastic wheels, silencer wheels, and wrinkled spoke wheels are also used abroad.
Adopt thin rim (thickness about 50mm)
Thin radial plate (usually the smallest is 9-15mm)
The thin wheel (wall thickness is about 30mm) adopts a tread shape suitable for high-speed operation and adopts a reasonably designed spoke shape (such as hyperboloid, double corrugated, large arc, etc. and all are connected by arcs)
