Control of TiN inclusion precipitation in bearing steel
-
摘要: 通過對軸承鋼中TiN夾雜析出的理論分析,得到不同凝固率下TiN夾雜析出溶解度飽和線,據此提出防止TiN夾雜析出的[Ti]、[N]控制范圍,同時提出了生產過程中[Ti]、[N]的控制措施.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.
