摘 要: 将皂化值不同的两种添加剂加入到基础油中配制成不同浓度的铝材轧制油,通过四球摩擦磨损试验考查添加剂的皂化值对轧制油摩擦学性能的影响,并通过四辊冷轧实验对轧制油轧制工艺润滑效果进行测试,结合退火清洁性实验对两种皂化值不同的添加剂进行综合评价。结果表明:皂化值较高的添加剂配制的轧制油表现出较好的抗磨减摩效果;随着添加剂含量的增加,极性分子在铝材表面的吸附量增大,轧制油的摩擦学性能增强,极压抗磨性能增强,且出现饱和吸附,添加剂皂化值越高,达到饱和吸附的速度越快;皂化值较高的添加剂对轧后铝材退火清洁性影响较小。

Abstract:Two kinds of additives with different saponification values were added to aluminum rolling oils. The effect of additives saponification value on the tribological properties of different rolling oils were examined by four-ball friction and wear testing machine. And the lubrication effect of rolling oils was actually verified by cold rolling. Finally, the kinds of additives with different saponification values were synthetically evaluated combining with the experiments of annealing clean. The results indicate that the rolling oils confected with the additive with larger saponification value show a better anti-wear performance. With increasing the additive content, the polar molecule adsorption on the aluminum surface increases, so the anti-wear performance is enhanced, and there is a saturated adsorption. The greater the saponification value of the additive is, the faster speed the absorption saturation achieves. The effect of the large saponification value of additives on the aluminum annealing cleaning after rolling is small.
