摘　　要：通过数值计算,对特定参数下凹凸面结晶辊熔池液面的波动进行研究。结果表明:平面结晶辊下熔池液面的波动不大,最大液面波动梯度为0.47 mm;而凹凸面结晶辊下液面波动剧烈,最大液面波动梯度为4.98 mm。因此,在通过凹凸面结晶辊引入振动时,应考虑对液面波动的影响。The concave-convex surface casting rolls are calculated numerically with certain parameters to analyze its effect on the pool level fluctuation.The results show the pool liquid level fluctuates slightly with the maximum gradient of 0.47mm in case of flat casting rolls,and fluctuates greatly with the maximum gradient of 4.98 mm in case of concave-convex surface casting rolls.For the reason,the influence of concave-convex surface casting rolls on the pool level fluctuation in molds shall be considered when they are used to generate vibration.
