摘　　要：为了研究熔渣中V2O5和R exOy对钢液氮含量的影响,选用C aO-S iO2-A l2O3系碱性渣作为基础渣系。通过对试验结果分析可知,熔渣中加入V2O5后,对钢液脱氮起了一定的作用,但效果不明显;渣中加入R exOy后,对钢液脱氮的影响不太明显,但是,它能够较好保护钢液,阻止钢液吸氮。In order to study the influence rules of V2O5 and RexOy in the ladle slag on nitrogen content in liquid steel, the basic slag system of CaO-SiO2-Al2O3 was chosen as a basic ingredient in the experiment, By analyzing experiment results, though V2O5 in the molten slag has a definite effect on removal of nitrogen, the function was not strong; RexOy. in the flux has a little influence on removal of nitrogen from the liquid steel, but it can protect molten steel from absorbing nitrogen from the atmosphere.
