摘　　要：通过光谱分析与定氧仪分别测定了钢水冶炼过程中Al质量分数与氧活性之间的动态平衡关系,以及对钢液深度脱S的影响进行了研究,结果表明:通过控制Al的加入量能够稳定地将氧活性降低到7×10-6以下,为深度脱S提供了有利条件。The dynamic equilibrium of aluminum and oxygen was measured by spectral analysis and oxygen analyzer. And its effect on the deep desulfurization was researched. The results showed the oxygen activity was decreased below 7ppm by the control of the A1 content, which provided favorable conditions for the deep desulfurization.

关 键 词：定氧仪 AL含量 氧活性
