讨论了连铸方坯中心偏析的成因 ,介绍了电磁搅拌、机械应力压下和二冷强冷模式等减少中心偏析的冶金技术 ,分析了铸坯断面大小对中心偏析的影响 ,并对宝钢拟建中的方坯连铸机的设备配置提出了几点建议
The causes of central segregation of continuous casting billet are discussed. The metallurgical techniques to reduce central segregation such as electromagnetic stirring, mechanical stress reduction and secondary cooling and strong cooling are introduced. The influence of slab section size on center segregation is analyzed. Bazhou billet caster equipment configuration made a few suggestions
