Production method of steel for railway locomotive parts: Most steel processing is to process steel through pressure, so that the steel (billet, ingot, etc.) to be processed produces plastic deformation. According to the different steel processing temperature can be divided into cold processing and hot processing two.

So how is steel, the main material for railway locomotive parts, produced? Rolling: The steel billet through the gap of a pair of rotating rolls (various shapes), due to the pressure of the roll to reduce the section of the material, the length of the pressure processing method, this is the most commonly used production of steel production, mainly used to produce profiles, plates, pipes. Cold rolling, hot rolling.

Forging steel: A pressure processing method that uses the reciprocating impact force of the forging hammer or the pressure of the press to change the blank into the shape and size we want. Generally divided into free forging and die forging, commonly used for the production of large profiles, billet and other materials with large cross-section size. Drawing steel: It is a processing method that reduces the section and increases the length of the rolled metal billet (type, tube, product, etc.) by drawing through the die hole, mostly used for cold processing.

Extrusion: is the steel is placed in a closed extrusion cylinder, one end of the pressure, so that the steel from the specified die hole extrusion and get a certain shape and size of the finished product processing method, mostly used in the production of non-ferrous metal steel.
