摘要
昆钢炼钢厂8号连铸机浇铸的碳素结构钢铸坯出现皮下夹渣缺陷。分析了中包液面高度、捞渣操作及脱氧工艺，结合铸坯皮下夹渣的分布情况及结晶器内浮渣中Al2O3、FeO等组成，对生产工艺进行优化，解决碳素结构钢连铸坯皮下夹渣问题。
The slag entrapment defect of carbon No. 8 caster at the Steel - making Plant of KISC. stuctural steel billet occurred, that was from the The liquid height of tundish, operation of slagging -off; deoxidation technique have been analyzed, combined distribution of slag entrapment defect and slag components of Al2O3 , FeO, etc. in the mold to optimize the production process to address the slag entrapment defect of carbon structural steel billet.
