| 摘 要： | 变形速度是轧制中的一个重要因素。导出粘着摩擦和滑动摩擦两种情况下,轧制变形速度的表达式。计算结果表明,粘着摩擦和滑动摩擦变形速度在轧件开始咬入附近处变形速度最大;在轧件与轧辊分离处,变形速度为零,在这点附近粘着摩擦和滑动摩擦变形速度值接近相等,摩擦系数几乎不影响滑动摩擦情况下的变形速度。

| Abstract: | Strain velocity is an important factor in rolling.Computing formula with adhesive friction and slide friction are obtained.Results of calculation prove that strain velocity has a maximum value near where rolling material begin to be bitten and strain velocity is zero at the point where rolling material leaves roller.Near the latter point,the strain velocity of adhesive friction and that of slide friction is near to be equal and friction coefficient has almost no effect to the strain velocity with slide friction. |

| Keywords: | rolling strain velocity adhesive friction slide friction friction coefficient |
