Reducing afterblowing and using the carburant with low nitrogen content are important measure. The kinetics of nitrogen removal from liquid steel under vacuum with reaction between carbon and oxygen was studied on the multi-function induction furnace. The following conclusions were obtained by experiments: The nitrogen removal was obtained by the nitrogen transfer through the liquid steel diffusion layer at 67Pa and 110Pa pressure, and by the gas-liquid surface chemical reaction at 2000P.

结果表明：真空度对脱氮机理有影响，67Pa～110Pa时脱氮为一级反应，2000Pa时脱氮为二级反应，1340Pa时为混合控制；即使在。1％的条件下，碳氧反应亦可显著提高脱氮速度常数促进深脱氮，在RH内通过加强碳氧反应来提高脱氮率理论上是可行的；当钢液内存在内生或外来固态粒子时，有利于钢液中CO及N〓气泡的形成及排除，这时气泡内p〓≈0，有可能使钢液中氮含量低干与系统真空度平衡的氮含量。
