Abstract
A thermal treatment and shot peening method for a wheel, including: heating a wheel blank to T1, and preserving the heat for t1; fast heating the wheel blank to T2, and preserving the heat for t2; performing quenching treatment, wherein a quenching medium is at temperature of T3, and the quenching transfer time is t3; performing aging treatment at aging temperature of T4, and preserving the heat for t4; performing first-stage shot peening; and performing second-stage shot peening.
Claims8
