| 摘 要： | 分析了连铸坯中夹杂物的来源和浇注过程中的二次氧化问题.介绍了国内外先进炼钢厂(新日铁、JFE、克鲁斯、迪林根、浦项和宝钢等)中间包夹杂物的去除与控制措施.通过增大中间包容量、采用H型中间包或离心流动中间包、设置中间包气幕挡墙和中间包控流装置,优化中间包结构.通过采用中间包密封吹氩技术控制中间包开浇的二次污染;采用汇流旋涡抑制器防止中间包浇注过程中卷渣;采用碱性包衬和碱性覆盖剂、中间包无氧化烘烤与电磁感应加热、中间包连续真空浇注处理和电磁过滤,可以降低钢水二次污染,防止二次氧化,促进夹杂物上浮,提高铸坯的质量.

| Abstract: | The source of inclusion in the continuous casting slab and reoxidation during the pouring process are analyzed.The measures of inclusion removal and control in the tundish in advanced steelmaking plants at home and abroad(such as Nippon Steel,JFE,Corus,Dillinger,Posco and Baosteel)are introduced.The conclusion is:the structure of the tundish can be optimized by increasing the capacity of tundish,using the type of H tundish or centrifugal flow tundish;secondary pollution during tundish free-opening can be co... |
