| 摘 要： | 应用CFX软件，模拟高拉速板坯连铸结晶器流场和液面波动，计算F数，研究了拉速、结晶器规格、水口参数、结晶器吹氩等因素对结晶器液面波动的影响。通过与F数对比，各因素对结晶器液面波动影响态势与F数基本一致。高拉速下，最佳F数值为3～5，此时结晶器液面波动小且平稳，结晶器液面钢液中心线流速为0．05～0．1m／s。

| Abstract: | The software CFX was applied to complete the numerical resolution of the flow field and surface wave of molten steel in mold for the high speed slab and the calculation to F constant. The effect of factors such as casting speed,dimension of mold, parameters of the submerged entry nozzle and flux of Ar, on surface wave of molten steel in mold were researched. Comparison with the F constant shows that various factors have the same influence on surface wave with the F constant. The optimum F constant is 3-5 in high speed, then the surface wave of molten steel in mold is short and steady, and the center steel velocity in mold surface is in 0.05-0. 1m/s range. |
