摘　　要：介绍了宝钢高碱度中间包覆盖剂的开发情况,指出提高中间包覆盖剂的碱度可有效防止中间包钢水回硫和覆盖剂本身污染钢液,对提高铸坯质量有重要的意义。Development of high basicity covering flux for tundish in Baosteel is introduced. It's pointed out that an increase in the basicity of the tundish covering flux is assumed to be an effective measure to prevent against return flow of hot metal into the tundish and eliminate the contamination of the hot metal by the covering flux itself, and therefore it's of great significance for improvement of the slab quality.
