摘　　要：在ANSYS-CFX13.0软件平台上,采用欧拉-欧拉法,针对各断面连铸结晶器采用不同类型水口的工况,在各拉速条件下分别建立模型进行数值模拟研究,并用现场生产过程的实际液面波动曲线进行了验证。通过研究发现:在1 200mm断面,使用凹型水口时结晶器液面波动较小;在1 500及1 800mm断面,使用凹型水口时结晶器液面波动较大。On the ANSYS-CFX13.0 software platform, the Euler--Euler method was used to establish numerical simulation models for conditions of different types of nozzles for casting moulds with different sections end various casting speeds, which were verified by level fluctuation curves in actual production process. Through the study we found that for the i200mm section the mould level fluctuation is smaller when using the concave nozzle, while for the 1500mm and 1800ram section the level fluctuation is bigger when using the concave nozzle.
