摘　　要：通过对钢包渣中V2O5,Nb2O5,La2O3等氧化物与氮反应的理论计算可知:在低压下,向还原性钢包渣中添加氧化物(V2O5,Nb2O5,La2O3),这些氧化物都可以与钢液中氮反应,对钢液脱氮有利;其中V2O5对钢液脱氮的促进作用明显大于其它两种氧化物;钢液在深脱氧的情况下,熔渣中这些氧化物都促进钢液脱氮。From the theoretical calculation of nitrogen reaction with oxides （V2O5, Nb2O5, La2O3） in the ladle slag, at the lower pressure, the oxides added to the reducing ladle slag may react with nitrogen in the molten steel, which is benefit for the nitrogen removal from the liquid steel; The accelerating role of vanadium oxide on the nitrogen removal from the molten steel is much stronger than that of the rest of oxides; Under the condition of the liquid steel that is deeply deoxidized, the oxides in the molten slag can promote the nitrogen removal ability of liquid steel.
