The invention discloses a non-homogeneous brake disc for a mine high-speed hoist. The non-homogeneous brake disc for the mine high-speed hoist comprises a base layer made of steel. A thermal barrier thermal insulation coating is arranged on the surface of the base layer made of steel, and an anisotropic high thermal conductivity coating is arranged on the surface of the thermal barrier thermal insulation coating. The radial thermal conductivity coefficient of the anisotropic high thermal conductivity coating is greater than the thermal conductivity coefficient in the circumferential and depthdirections. The thermal conductivity coefficient of the base layer is greater than that of the thermal barrier thermal insulation coating. The specific heat capacity coefficient of the thermal barrierthermal insulation coating is greater than that of the base layer and the anisotropic high thermal conductivity coating. The thermal expansion coefficient of the base layer is greater than that of the thermal barrier thermal insulation coating and the anisotropic high thermal conductivity coating. The temperature distribution and thermal deformation of the brake disc in the high-speed braking process can be improved, and the braking safety of the high-speed hoist is improved.
