针对铝板带冷轧过程中的润滑状态、润滑作用机理及对轧后表面质量的影响进行深入研究。在四球摩擦磨损实验中测试分析了轧制油的摩擦学性能,进而在轧制实验中获得了轧制润滑特征曲线以及不同的润滑条件下轧后表面形貌和粗糙度。结果表明:铝板带冷轧变形区润滑状态为边界润滑,可以获得优异的轧后表面质量,同时与无润滑轧制相比,在边界润滑状态下轧制,其最小可轧厚度最大可降低50%,表面粗糙度Ra最大可减小53%。 Aiming at the lubrication state during cold rolling process of aluminum strip, the lubricating mechanism and the influence on the surface quality after rolling are studied deeply. In the four-ball friction and wear test, the tribological properties of the rolling oil were analyzed and analyzed, and the rolling lubrication characteristic curves and the surface morphology and roughness after rolling under different lubrication conditions were obtained. The results show that the lubrication state of cold deformation zone of aluminum strip is boundary lubrication, which can obtain excellent surface quality after rolling. Compared with the non-lubrication rolling, rolling at boundary lubrication can reduce the minimum rolling thickness by 50 %, The maximum surface roughness Ra can be reduced by 53%.
