摘要
宣钢二钢轧厂结合实际生产情况,对铸坯表面缺陷、内部缺陷和外形缺陷的表现形式和产生原因进行了全面梳理和总结。通过完善典型拉速规范、建立科学规范的结晶器使用制度、老化设备升级改造、翻钢系统液压缸关键部件改造等措施,实现了无缺陷铸坯的生产,满足了棒材热热轧铸坯的质量要求。
According to the actual production situation in the rolling plant of No.2 Steel of Xuanhua Steel Co.,Ltd.,the forms and causes of surface defects,internal defects and shape defects of the slab are comprehensively summarized.Through improving the typical drawing speed specification,establishing a scientific and standardized mold use system,upgrading and reforming the aging equipment,and reforming the key components of the hydraulic cylinder of the steel turnover system,so that the production of defect free billets has been realized,and the quality requirements of hot rolled billets for bars have been met.
