本文讨论在RH处理时钢中夹杂物的去除效果,给出钢中氧化物夹杂含量与RH环流时间的一级反应式。经RH-OB处理的钢中,有较大尺寸的氧化物夹杂。
In this paper, the removal of inclusions in steel during RH treatment is discussed, and the first-order reaction equation is given for the amount of inclusions in steel and RH circulation time. In RH-OB-treated steels, larger oxide inclusions are present.
