改善X12Cr13小方坯低倍质量

Improving macroquality of X12Cr13 billet

本文重点分析了150×150mm X12Cr13不锈钢铸坯低倍产生中心裂纹的成因,通过提高拉速、提高末搅电流、降低钢中硫含量的措施有效地改善了中心裂纹缺陷程度。

The forming causes of the center crack in macrostructure of 150×150mm X12Cr13 stainless steel billets are analyzed mainly.The defect degree of the central crack has been effectively improved by increasing the pulling speed,increasing the final stirring current and reducing the sulfur content in steel.
