摘要
利用商业Phoenics软件对某钢厂230 t钢包底吹氩精炼钢包内钢液的流场进行数值模拟计算,并从流场分布和湍动能分布等角度分析了不同喷嘴布置和不同吹气量对钢包内钢液混匀效果的影响。结果表明,底吹氩钢包内透气元件采用0.6R-β布置可避免钢液对包壁所造成的严重冲刷,且有利于减少钢包内钢液的混匀时间,从而获得较为理想的搅拌效果。
By means of Phoenics, a commercial software, the flow field of the molten steel in a 230 t LF is simulated, and the effect of nozzle layout and flow rate on the mixing of the molten steel is stud- ied from the perspectives of kinetic energy distribution and flow field. The results show that 0.6R-β scheme can reduce the corrosion effectively and lead to a better mixing effect.
