摘　　要：通过建立的水模型和三维Enler数学模型,试验研究了80 t LF底吹偏心位置对钢水混匀时间和钢包纵截面流场的影响。结果表明,最佳底吹偏心位置为0.550R(钢包半径),使混匀时间短,具有较佳的流场分布,有利于夹杂物上浮与去除。The effect of bottom blown location of an 80 t LF on mixing time of liquid steel and liquid flow field of ladle longitudinal section have been tested and studied by established water model and three dimensional Euler model. Results showed that the optimum bottom blown location was 0. 550R （ ladle radius） , it was available to decrease mixing time and promote inclusions floating up and removed with optimum distribution of liquid flow field.
