摘　　要：针对半镇静钢H08E易产生皮下气泡的原因进行了分析，分析表明，将钢中氧含量控制在0．0015％-0．0045％可避免铸坯皮下气泡的产生。The cause of semi-killed steel H08E prone to subsurface blowholes is analyzed and discussed In this paper. The analysis shows that controlling the oxygen content in 0.001 5%-0.004 5% can avoid the occurrence of subsurface blowholes.

关 键 词：半镇静钢 皮下气泡 化学成分 氧含量
