Abstract The quality of cold-rolled aluminum products is dependent on a low surface roughness and a high surface finish. Accordingly, the present study develops a mixed lubrication model to examine the effects of the main rolling parameters. Cold rolling experiments are then performed on laboratory-scale high-speed cold mill system to evaluate the surface roughness and surface gloss of aluminum sheets processed under different operation conditions. The gloss measurements show that a lower proportion of protrusion of the bearing area ratio leads to a higher gloss of the rolled surface. Overall, the present theoretical and experimental results show that the surface quality of cold-rolled aluminum sheets can be enhanced through the use of a higher reduction rate or a lower roll speed.

冷轧操作参数对铝表面光洁度的影响

摘要 冷轧铝制品的质量取决于低表面粗糙度和高表面光洁度。因此，本研究开发了一种混合润滑模型来检查主要轧制参数的影响。然后在实验室规模的高速冷轧系统上进行冷轧实验，以评估在不同操作条件下加工的铝板的表面粗糙度和表面光泽度。光泽度测量表明，轴承面积比的突出比例越低，轧制表面的光泽度越高。总的来说，目前的理论和实验结果表明，冷轧铝板的表面质量可以通过使用更高的压下率或更低的轧制速度来提高。
