【摘要】 在真空或真空低吹氩条件下，研究了ＣａＯ－ＢａＯ－Ａｌ_２Ｏ_３－ＴｉＯ_２，ＣａＯ－ＭｇＯ－Ａｌ_２Ｏ_３－ＳｉＯ_２－ＣａＦ_２渣对钢液脱氮的影响。结果表明，熔渣降低真空脱氮速率，底吹氩能减少熔渣对真空脱氮的阻力。更多还原

【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.更多还原
