Method for improving surface quality of grinding wheel peeled bar for cold drawing

The invention belongs to the technical field of steel rolling finishing, and discloses a method for improving the surface quality of a grinding wheel peeled bar for cold drawing. According to the technical requirements for specifying grinding wheel materials and the like, the number of opened grinding heads of the grinding wheel peeling machine is adjusted, grinding wheels with different mesh numbers are used in a front-back matched mode, the pressure of a grinding head air cylinder, the cooling water flow and the peeling feeding speed are controlled, and the defects of transverse linear small cracks, bluing, scorching, pits, correcting marks and the like on the surface of a grinding wheel peeled bar are overcome; and meanwhile, the surface roughness is reduced, so that the surface quality of the bar is improved, a turning peeling process can be replaced, the use requirements of downstream cold drawing users are met, and remarkable economic benefits and social benefits are achieved. 本发明属于轧钢精整技术领域，公开了一种提高冷拉拔用砂
