The groovy ripple was caused by polygonal effect of the chain and its craw in the equipment,or unexpected impact and vibration in production process.
针对生产中铝锭表面出现的飞边、夹渣、表面波纹过大等影响外观质量的因素,从生产实际出发,分析认为由于铝液流量不稳或扒渣速度过快而形成飞边、夹渣;由于扒渣不平稳形成同心圆状水波纹;由于水的汽化和氢气的逸出形成泡状水波纹;从设备本身的结构分析认为由于链条的多边形效应和爬行以及在生产过程中的冲击、振动等是产生沟槽状水波纹的原因。

补充资料：凹多边形

凹多边形
把一个各边不自交的多边形任意一边向两方无限延长成为一直线，如果多边形的其他各边不在此直线的同旁，那么这个多边形就叫做凹多边形。
凹多边形的内角和的解，其实我们可以通过（n-2）·180来计算。实际上是把大于平角的角划分为两个角（如图）
