摘　　要：在CFD软件平台上进行喷吹颗粒镁铁水脱硫数值模拟,通过改变喷枪插入深度、载气流量等参数,探究其对脱硫过程中铁水罐内流场以及混匀死区的影响。结果表明,在一定条件下,增大喷枪插入深度、适当降低载气流量均可改善喷吹颗粒镁的动力学条件,增强脱硫效果。The numerical simulations on the hot metal desulfurization by injecting granular magnesium were carried out in CFD software platform through changing the insertion depth of injection lance, carrier gas flow rate to explore the effect of these process parameters on the flow field inside the iron ladle and blending dead zone. The results showed that under given conditions, the dynamics condition and desulfurization efficiency of granular magnesium could be improved by increasing insertion depth of injection lance, properly lowering carrier gas flow rate.
