Steel Rails are mainly used on railways or in some industrial occasions.  Its use can make the road smoother, and it will not be affected by ordinary rain and snow weather. It can be used as usual.  This is mainly due to the scraping of the upper surface of the rail and the smooth operation.

Only strict requirements can make a good product. Let's look at what the rail production technology explained to you by the rail manufacturer includes.

External refining and vacuum degassing technologies are adopted to ensure the internal quality of steel billet, control the content of residual elements and gases in steel and ensure the purity of steel.steel rail China manufacturer

Continuous casting bloom is adopted, which is mainly to improve the macrostructure of billet.  Using walking-beam heating furnace to heat billet can effectively control the atmosphere in the furnace and prevent steel from decarburization and uneven heating temperature during heating.

High pressure water descaling technology is adopted.  Can greatly reduce the occurrence of defects such as rolling marks caused by iron scales.steel rail China manufacturer

Universal pass design and computer on-line adjustment of rail geometry are adopted to ensure the rolling accuracy of rail section.

Long-gauge rolling, long-gauge cooling, reverse pre-bending and long-gauge straightening processes are adopted to improve the yield, reduce the bending degree before straightening and the residual stress after straightening, and improve the fatigue life of the rail.steel rail China manufacturer

Using on-line quality inspection technology, through ultrasonic, eddy current and laser inspection of the rail, the internal, surface quality and geometric dimensions of the rail can be fully understood.

High machining accuracy can be obtained by using a saw and drill machine with hard alloy to machine and drill the end of the rail.
