Abstract

Abstract

Under vacuum or vacuum argon blowing conditions,the influences of CaO-BaO-Al₂O₃-TiO₂ and CaO-MgO-Al₂O₃-SiO₂-CaF₂ slags on denitrogenation from steel were investigated.It is found that slags decrease the rate of vacuum denitrogenation and vacuum argon blowing decreases the denitrogenation resistance of slags.
- molten slag,
- vacuum denitrification,
- mass transfer rate
