摘要: 通过1:6的水力学模型,对顶枪枪位、顶枪气体流量、底吹气体流量、底部供气元件的布置等影响提钒转炉混匀时间的因素进行研究和优化。确定最佳喷吹方案为:枪位183.3 mm,顶吹气体流量85.6 m3/h,底吹气体流量1.05 m3/h;最佳底枪布置方案为:8支底枪分两组布置在转炉底部直径0.4D和0.6D的两个环上,相邻4支底枪成菱形排列。Abstract: The effect of the lance level,the flow rate of top lance,the flow rate of bottom blowing and the bottom tuyeres' configuration on mixing time of fluid in 150 t vanadium extraction converter has been studied and optimized by water model experiment with similarity ratio 1:6.The best blowing case is that lance level is 183.3 mm,flow rate of top lance is 85.6 m3/h and flow rate of bottom blowing is 1.05 m3/h.The best bottom tuyeres configuration is case 2,eight bottom tuyeres are divided into two groups and fixed on the two rings of converter bottom,the diameters of the rings are 0.4D and 0.6D;the four adjacent bottom tuyeres are arrayed rhombic.
