| Zusammenfassung: | The invention provides a martensite, bainite and austenite grinding ball continuous isothermal quenching heat treatment method and device. The martensite, bainite and austenite grinding ball continuous isothermal quenching heat treatment method comprises the steps that firstly, grinding balls are austenitized and then put into heat treatment roller circulating water to be subjected to water cooling, the temperature of the grinding balls is within the bainite transformation temperature range after water cooling heat treatment, the grinding balls are taken out and put into a heat preservation furnace to be subjected to isothermal tempering, and the martensite, bainite and austenite grinding balls are obtained. The martensite, bainite and austenite grinding ball continuous isothermal quenching heat treatment method and device have the advantages that the cooling speed of the grinding balls is accurately controlled by adjusting the water level height, flow, water temperature and roller rotating speed in a roller, |
