Rail steel is usually used for railway fixed on the sleeper, sleeper for ballast. It is fastened by rail support, fastener, rail press, track splint, elastic bar, railway spike and other railway accessories. The bottom of the track is the track bed, which provides elasticity and drainage function for the track. Rails can also be laid on bases made of concrete, or even embedded in concrete. In order to withstand the pressure, impact load and friction of train operation, it requires sufficient strength and certain toughness. Quality requirements are strict, in addition to the guarantee of its chemical composition, but also require the inspection of mechanical properties, drop weight test and acid leaching of low-power tissue.

Spiral steel pipe is a spiral seam steel pipe made of strip coil plate, extruded at constant temperature and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe will send the strip into the welding pipe set. After being rolled by a multi-channel roll, the strip gradually rolls up to form a circular tube blank with an open gap. The pressure of the extrusion roll is adjusted so that the weld gap is controlled within 1~3mm and the two ends of the welding joint are flush.

Hot rolled steel plate is made of continuous casting slab or rolling slab as raw material, heated by stepping furnace, descaled by high pressure water into roughing mill, roughing mill through cutting head, tail, and then into finishing mill, implementation of computer controlled rolling, after the final rolling after laminar cooling (computer controlled cooling rate) and coiler winding, straight coil. The head and tail of straight hair curl are often tongue and fishtail, and the thickness and width are poor. The edge often has defects such as wave shape, hem and tower shape. Its coil weight is heavy, the inner diameter of the steel coil is 760mm.

Cold rolling is made of hot rolled plate coil as raw material, rolled at normal temperature under the recrystallization temperature, cold rolled steel plate is produced by cold rolling process, referred to as cold plate. The thickness of cold-rolled plate is generally between 0.1 and 8.0mm, and the thickness of cold-rolled plate produced by most factories is below 4.5mm. The thickness and width of cold-rolled plate are determined by the equipment capacity of each factory and the market demand.
