摘　　要：根据全浮力物理模型，应用动量定理建立钢包庇吹中粉气液三相区中平均速度和液体平均体积浓度的全浮力数学模型．计算结果表明：三相区中平均速度随高度的增加而减少，液体平均体积浓度随高度的增加而增大；粉气液三相区锥角和液体密度随着高度的增加对平均速度和液体平均体积浓度的影响逐渐减小．Based on the plume physical model,a mathematical model describing mean velocity and liquid volume concentration of particle--gas--liguid three phase now in bottom--blown ladle is established. The calculating results show that mean velocity is decreased with increase of the height and liguid volume concemtration is increased with increase of the heigh As the height increasing,the effects of the conical angle in three phase flow and the nquid density on the mean velocity and liquid concentration are decreased.
