摘要: 通过1:3.5水模型研究了宝钢300 t铁水包双枪喷吹脱硫时,喷枪插入深度、气体流量、喷吹位置对均混时间的影响。结果表明,偏心喷吹的搅拌效果优于中心喷吹;喷枪插入越深,均混时间越小,但对底部耐火材料冲击加大;气体流量增加,铁水包内回流区增加,均混时间减小;喷枪弯曲时均混时间比同一工况直喷枪喷吹减少10%~30%。

Abstract: Effect of lance inserting depth, gas flow rate and injection location on mixing time for a 300 t hot metal desulphurization-pretreated by double-lance injection process at Baosteel has been studied by 1 :3.5 water modelling. Results showed that the effect of stirring by off-centre injection was better than that by centre injection ; the deeper the insertion lance, the shorter the mixing time, but the impact to refractory in bottom increased; with increasing gas flow rate the return flow zone increased and the mixing time decreased ; and the mixing time for injection by bending lance decreased by 10% ~30% as compared with that by straight lance.
