抄録

The effect of soluble oxygen on the reoxidation behavior by slag has been investigated by comparing the oxygen content and oxide formation of non-killed steel containing a soluble oxygen content of approximately 50 to 250 mass ppm with those of Al-killed steel containing less soluble oxygen. In the non-killed steel, oxides are not formed in molten steel even when oxygen is supplied from slag because it does not contain aluminum which has strong affinity for oxygen. The soluble oxygen content simply increases. In the Al-killed steel, however, the oxygen supplied from slag reacts with aluminum to form alumina and most of them float out.
