摘　　要：以自主研发的凹凸结晶辊为基础,采用数值模拟方法对铸轧熔池内不同结晶辊辊面结构下的弯月面进行分析。结果表明:在平辊条件下,从0 s到0.06 s期间,熔池弯月面高度快速增加,从0.06 s到0.1 s期间熔池弯月面高度趋于稳定;在凹凸结晶辊条件下,结晶辊振幅对于弯月面高度的影响大于结晶辊频率,弯月面高度的最大值发生在R=1 mm,f=36下,为20.4 mm,弯月面高度的最小值发生在R=0.5 mm,f=24下,为13.0 mm。To find out the advantage of the concave-convex casting roll that has been developed independently over conventional casting rolls,the behavior of meniscus in the mold of roll casting machines with casting rolls in different surface structure is analyzed by means of numerical simulation.The result shows that with flat casting rolls,the meniscus level increases rapidly form 0 s to 0.06 s and keeps nearly stable from 0.06 s to 0.1s;with concave-convex casting rolls,the effect of the vibration amplitude on the meniscus is higher than the vibration frequency:the highest level of 20.4mm occurs when R=1 mm,f=36 and the lowest level of 13.0 mm occurs when R=0.5 mm and f=24.
