【摘要】 在连续铸钢生产中,尤其对高碳钢,中心偏析是一种常见的有害缺陷。本文对二冷区位置电磁搅拌改善连铸方坯的中心偏析进行了实验研究。结果表明,搅拌工艺选择适当可较好地改善连铸坯中心偏析;反之则会导致中心偏析无变化或更严重。更多还原

【Abstract】 In continuous cast billet, the center macrosegregation is a kind of very harmful defect, especially for high-carbon steels. The improvement on center macrosegregation with EMS was studied in this paper. The results indicate that proper stirring conditions can largely reduce the center macrosegregation; otherwise, the improper stirring condition will increase the center macrosegregation.更多还原
