变形区几何形状对摩擦系数μ的影响是有条件的。对莱式拉和宋冀生的实验结果作了不同的解释。提出在轧辊直径不相等的条件下,才得到此结果:“当增大时,μ呈非线性下降”。
The effect of deformation zone geometry on the friction coefficient μ is conditional. The experimental results of Lailai and Song Jisheng were explained differently. It is proposed that this result is obtained when the roll diameter is not equal: “When increasing, μ is non-linearly decreasing.”
