摘　　要：在冶炼含氮超低碳钢时,鉴于铁液中铝和钛对氮溶解度的影响,氮气在RH精炼氮合金化过程中可以作为环流气体用来控制增氮。在不同RH精炼阶段用于控制氮元素增量的增氮系数通过试验获得。主要控制参数包括RH精炼过程中的环流氮气流量、真空度选择、增氮时间等。In the production of nitrogen containing ultra low carbon steel, nitrogen can be used as the circulation gas to control nitrogen increase during nitrogen alloying in RH refining process considering the influence of aluminum and titanium on nitrogen solubility in molten iron. Nitrogen increase coefficients which can be used for nirtrogen control in different stages of RH refining process are obtained by tests. The main control parameters include circulating nitrogen flowrate, vacuum degree and nitrogen increasing time etc. in RH refining.
