一、前言用惰性气体净化钢液近年来得到广泛的应用。最近发展的氧气底吹转炉,在吹炼末期常通过鼓氮30秒钟左右,来减少钢水含氢量。我们用电化学电池直接定氧,对氧气底吹转炉鼓氮前后钢水氧含量进行了研究。实验表明,通过吹炼末期30秒钟左右 I. INTRODUCTION Purification of molten steel with inert gas has been widely used in recent years. The recent development of oxygen bottom blowing converter, often in the final stage of blowing through the drum of nitrogen 30 seconds or so, to reduce the hydrogen content of molten steel. We use electrochemical cells directly oxygen, the oxygen at the bottom of the converter drum before and after the drum oxygen content of oxygen were studied. Experiments show that by blowing the end of about 30 seconds
