Abstract:The formation and hazard of the carbide band structure for bearing steel were introduced. In order to get the minimal level of bearing steel banded structure, the effects of the bearing steel products annealing procedure on the level of bearing steel banded structure was researched. Taking 4 groups of annealing process to make comparison, it was determined that the level of banded structure was increased with 1.0 level after the spheroidizing annealing of bearing steel. And the results show that the carbide precipitation and the banded structure level could be reduced with fast cooling between the 710—800℃ in the period of the spheroidizing annealing of the bearing steel.
