The company has developed a heat treatment and cooling process for railway wheels, which belongs to the technical field of heat treatment and cooling of railway wheels. The method steps include: firstly heating the wheel as a whole to complete austenitization; then transferring it to a quenching table to keep the wheel in a rotating state, and spraying the wheel tread with a pressure step-increasing aerosol two-phase flow; and then placing the wheel as a whole into a tempering furnace for heat preservation , and finally take out the air cooling; the pressure step-increasing aerosol two-phase flow jetting wheel tread includes three stages in turn, controlling the wheel speed v1>v2>v3 in the three stages, and the water pressure P1
