Production of high-quality railroad wheels

A new technology is proposed for improving the railroad wheels produced at OAO Nizhnetagil’skii Metallurgicheskii Kombinat. Mathematical simulation of the stamping of continuous-cast billet provides information on the change in shape of the metal. The factors responsible for the poor quality of the rough wheels produced by the SMS EUMUCO method are identified. Two new stamping methods are developed, on the basis of three characteristic stages of metal flow.
