The invention provides thermal-damage-resistant heavy-load wheel steel, a wheel, a wheel production method and application. The thermal-damage-resistant heavy-load wheel steel comprises the following components: 0.67%-0.70% of C, 0.90%-1.00% of Si, 0.80%-0.90% of Mn, less than or equal to 0.015% of P, 0.006%-0.015% of S, 0.05%-0.15% of V, 0.20%-0.30% of Cr, 0.0050%-0.0100% of N and the balance of Fe and inevitable impurity elements. Compared with the prior art, through reasonable regulation and control of C, Mn, Si, Cr and V elements, design of a quenching heating temperature formula and adoption of a heat treatment method of flow incremental quenching and constant flow quenching, an ideal fine pearlite and ferrite structure is obtained, the mechanical property level of a rim is higher, the wear resistance of a wheel is effectively improved, the toughness of the wheel is improved, and the service life of the wheel is prolonged. And the thermal damage resistance of the wheel is enhanced.
