Abstract

Abstract

Based on the theoretical analysis of TiN inclusion precipitation in bearing steel, the saturation solubility curves of TiN inclusion precipitation under different solidification rates was calculated. The control range for[Ti] and[N] is proposed to prevent TiN inclusion precipitation, and control measures for[Ti] and[N] are raised in the production process.
- bearing steel,
- TiN,
- solidification segregation,
- solidification rate,
- protective casting
