Abstract��Aiming at the abnormal breakdown problem of the train wheel forging mould�� by means of the chemical analysis�� macro acid pickling�� mechanical test�� micrographic examination�� fracture analysis etc�� the crack of wheel forging mould was analyzed. The results showed that the inappropriate material and the non-uniformity of heat treatment were the mainly reasons of the crack. And the recommendations of preventing the fracture and prolonging service life were provided.
