The service life of KR impeller for one steel plant in Southern China is investigated in this paper. It is shown by site investigation and comparison analysis that there is still improving potential for the service life of KR impeller, whose influencing factor includes hot water temperature, rotating speed, stirring duration, refractory of working lining, internal metal core structure, fabricating process, blade structure, hot repairing process and material, desulfurizer composition, interval time between stirrings. If technical optimization is conducted based on the influencing factor, it is predicted that the service life of KR impeller in this plant can be enhanced from 230 heats to 300 or 400 heats, saving 0.4~0.6 RMB/t hot metal.
Key words: Hot metal / KR / Impeller / Desulfurization
