Quick-edging rail-burning-free steel rail grinding wheel

The utility model discloses a quick edging non-burning steel rail grinding wheel which comprises an aluminum alloy base body and a grinding body, a glass fiber reinforcement layer is sleeved outside the grinding body, and the grinding end face of the grinding body is provided with a protrusion and a chip containing heat dissipation groove. Compared with the prior art, the steel rail grinding wheel has the advantages that the structure of the grinding wheel grinding end face is designed, and the protrusions and the chip containing heat dissipation grooves are formed in the grinding wheel grinding end face, so that heat dissipation can be accelerated through the chip containing heat dissipation grooves in the grinding end face even if the grinding wheel grinding end face is not edged in the initial grinding stage of a new grinding wheel steel rail; the bluing phenomenon of the steel rail is solved; meanwhile, heat generated in the polishing process can be reduced through the protrusions on the polishing end fac
