摘　　要：运用fluent 6.3对板坯连铸结晶器进行数值计算,研究结晶器宽度对流场的影响。结果表明:对于230mm厚结晶器,随结晶器宽度增加,其液面的最大水平流速减小,但减小的幅度趋缓,液面最大垂直速度和冲击点处速度逐渐减小;宽度分别为1 400、1 600和2 150mm时,液面水平流速达到最大时分别为距离窄边460、540和750m处,冲击点位置分别距离液面0.37、0.40和0.46m,冲击点的速度分别为5.2、4.4和2.5cm/s。Slab continuous casting mould was calculated by software fluent 6.3,the effects of mould width on the flow field were investigated.It is concluded that： as for mould of 230mm thickness,as the increase of mould width,maximum horizontal velocity on the level liquid decreases,then approaches to a flat,maximum velocity perpendicular to level liquid and velocity of impact point on the narrow side decrease;when the mould width are 1 400 mm,1 600 mm and 2 150 mm,and the distance to the narrow side are 460 mm,540 mm and 750 mm,horizontal velocity on the level liquid reach the maximum,the impact points on the narrow side are 370 mm,400 mm and 460 mm to the level liquid,and the velocity on the impact point are 5.2 cm·s-1,4.4 cm·s-1 and 2.5 cm·s-1.
