description The invention discloses a surface quenching technology of a high-strength alloy steel track shoe and belongs to the technical field of casting. The surface quenching technology mainly solves the technical problem that the depth of a quenching layer on the surface of an existing casting is small. According to the technical scheme, the surface quenching technology of the high-strength alloy steel track shoe comprises the following steps that (1), a simulation test block is cast; (2), each test parameter is adjusted on the test block in the step (1); 3), surface quenching treatment is carried outon the high-strength alloy steel track shoe according to the parameters obtained in the step (2); and (4), after surface quenching treatment is completed, the high-strength alloy steel track shoe istaken out and subjected to tempering treatment, and the high-strength alloy steel track shoe with the surface quenching layer depth being 25 mm can be manufactured. The technology has the beneficial effects that technology def
