摘 要: 將皂化值不同的兩種添加劑加入到基礎(chǔ)油中配制成不同濃度的鋁材軋制油，通過四球摩擦磨損試驗(yàn)考查添加劑的皂化值對軋制油摩擦學(xué)性能的影響，并通過四輥冷軋實(shí)驗(yàn)對軋制油軋制工藝潤滑效果進(jìn)行測試，結(jié)合退火清潔性實(shí)驗(yàn)對兩種皂化值不同的添加劑進(jìn)行綜合評價(jià)。結(jié)果表明：皂化值較高的添加劑配制的軋制油表現(xiàn)出較好的抗磨減摩效果；隨著添加劑含量的增加，極性分子在鋁材表面的吸附量增大，軋制油的摩擦學(xué)性能增強(qiáng)，極壓抗磨性能增強(qiáng)，且出現(xiàn)飽和吸附，添加劑皂化值越高，達(dá)到飽和吸附的速度越快；皂化值較高的添加劑對軋后鋁材退火清潔性影響較小。

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.
