Abstract: The types and sources of inclusions in bearing steels are analyzed, and the problems existing in controlling inclusions during bearing steel manufacture processes are discussed. The main harmful inclusions in bearing steels are complex oxides and oxysulphide inclusions with Al2O3 formed during deoxygenation as a core. Some main measures to reduce oxide inclusions in bearing steels are as follows: controlling end-point carbon content in primary melting furnace, selecting suitable deoxidizer to improve deoxidization ability or to degenerate the inclusions, optimizing the composition of refining slag to increase the ability of inclusion removal, optimizing smelting process to decrease the number of large-size inclusions and improve their distribution in bearing steels. The technology progress direction for controlling inclusions in bearing steels is pointed out.
