摘要

通过10 ： 1水模型研究了转炉底吹流量0.55 -0.75 m

/h和底吹喷嘴4孔对称、2孔对称、2孔不对称分布以及喷嘴位置d/D = 0. 1 ~0.9(d-喷嘴所在同心圆直径

Z)-转炉熔池直径)对熔池均混时间的影响。结果表明

d/D=0. 3

底吹流量0.70 m3/h

4孔对称底吹时熔池搅拌效果最佳;2孔不对称喷吹时，最佳流量为0. 60-0.70 m

最佳喷嘴位置d/D=0. 3 ~0.5；2孔对称喷吹时最佳流量与喷嘴位置分别为0. 65 m

/h和d/D=0. 7。

Abstract

The effect of converter bottom gas flow rate 0. 55 -0. 75 m

distribution of bottom nozzle with 4 hole symmetry

2 hole symmetry and 2 hole non- symmetry and blowing location d/D = 0. 1 - 0. 9 (d- diameter of concentric circles of located nozzle ； D- diameter of converter bath) on bath mixing time has been studied by 10 ： 1 water modelling. Results showed that the stirring effect for 4 hole symmetry bottom blowing with d/D = 0. 3 and flow rate 0. 70 m

/h was optimum

the stirring effect for 2 hole symmetry bottom blowing with 0. 60 ~ 0. 70 m

/h and d/D = 0. 3 ~ 0. 5 was optimum

and that for 2 hole non-symmetry was respectively 0. 65 m

/h and d/D = 0. 7.
