摘要
针对莱钢Ф350mm圆坯存在的中心裂纹、疏松等质量缺陷,通过控制钢中[%C]含量,降低钢水过热度,提高连铸设备对弧精度,优化二冷系统、拉速及浸入式水口插入深度等措施,铸坯中心质量缺陷基本消除。
In view of the existing Ф350mm round billet quality defects such as center cracks,center porosity,by controlling the content of[%C]in steel,lowering the temperature of the liquid steel,improving the accuracy of arc continuous casting equipment,optimization of two cooling system,pulling speed and immersion depth of nozzle,quality defects with the billet center are basically eliminated.
