摘　　要：通过对密封罩吹氩喷粉设备工艺的设计应用，研究了喷粉脱硫过程中钢液氮含量变化。试验结果表明，密封罩喷粉工艺降低了钢液面氮分压，不仅能够防止钢液吸氮，还具有一定的脱氮效果。The variation of nitrogen content in molten steel ha s been studied by Argon\|powder injection apparatus with sealing cover. The re sults showed that the partial pressure of nitrogen at molten steel surface redu ced by using the technology of argon\|powder injection with sealing cover, by wh ich to prevent the nitrogen absorption and promote the nitrogen removal.
