连铸超低碳IF钢的工艺实践

Process Practice on Ultra-low-carbon IF Steel with Continuous Casting

柳钢采用铁水预处理→BOF→RH→板坯连铸生产超低碳IF钢,介绍连铸过程中保护浇注、水口结瘤、钢水增碳等方面的控制措施及效果。

Liuzhou Steel adopts the process： molten iron pretreatment → BOF → RH →slab contin- uous casting to produce ultra-low-carbon IF steel, and the control measures such as protective casting, nozzle blocking and carbon increase in molten steel during continuous casting were introduce.
