Abstract: The surface quality of the IF steel strips rolled without lubrication and with two different emulsions lubrication was analyzed, and the reasons for the difference of surface quality lubricated by different emulsions were studied by analyzing the tribological properties of emulsions. The results showed that the lubrication of emulsions in cold rolling process could make the steel strip surface more smooth and improve the surface quality. The reason for the better surface quality of the steel strip lubricated by LP-2 than lubricated by LP-1 is mainly that the LP-2 emulsion had higher oil film strength which could form more stable oil film in the lubrication process, and get better anti-friction and anti-wear effects.

摘要： 分析了无润滑和釆用两种不同乳化液润滑轧后IF钢板表面质量，并通过对乳化液摩擦学性能分析研 究了造成轧后表面质量差异的原因。研究发现，釆用乳化液润滑可以使轧后钢板表面更加平整、光滑，改善表面质 量;LP-2润滑时轧后钢板表面质量比使用LP-1润滑时更好，主要是因为LP-2乳化液其油膜强度更高，润滑过程中 油膜更加稳定，抗磨减摩效果更好。
