前滑 轧制过程中,被轧金属的出口速度大于轧辊圆周速度的现象,其描述参数称为前滑值,也简称为前滑,定义为 式中S为前滑值,Vh为轧件出口速度,Vr为轧辊圆周速度。前滑是轧制时金属纵向延伸和摩擦力作用的结果。研究前滑的意义在于:前滑的测定比较简单和直观,可由前滑来分析和推测金属在变形区内的流动情况。例如可由前滑推断理想的变形区内存在着前滑区、后滑区和中性面;后滑为金属入口水平速度小于轧辊圆周速度,中性面上各点的金属速度与轧辊圆周速度相等,与中性面相应的圆心角叫做中性角,如图所示。在实际工作中,连轧时为使相邻机架间轧辊速度能够配合好,必须考虑前滑值。 影响前滑的因素很多,不同的简化可得到各种计算公式。其中最简单的是德雷斯登 (D.Dresden)于1915年按轧件秒流量体积不变条件和均匀变形假设求出的公式: 式中S为前滑,γ为中性角,h1为金属轧后厚度,R为轧辊半径。
