摘　　要：将油溶性纳米Cu(n-Cu)微粒作为添加剂用于板带钢冷轧乳化液中,考察了其对乳化液极压性能和摩擦学性能的影响,在JC2000C1润湿角测试仪上测定了乳化液在带钢表面的润湿性能,并在四辊冷轧试验机上进行了乳化液润滑下的板带钢冷轧试验。结果表明,在板带钢冷轧乳化液中添加0.06%质量分数的n-Cu后,能更好地改善乳化液的极压抗磨性能/降低钢、钢摩擦系数;提高乳化液在带钢表面流动润湿性能的同时,还表现出良好的板带钢冷轧润滑效果,可明显降低板带钢最小可轧厚度,并可以改善轧制带钢板形和表面质量。Oil-soluble nano-copper （n-Cu） was used as an additive in the strip cold rolling emulsion, and the extreme pressure properties and the tribological properties of emulsion doped with n-Cu were evaluated by using a four-ball machine. At the same time, the flow performance of the emulsion on the surface of strip steel was tested by JC2000C1 wetting angle machine, and the lubricity of the cold-rolling emulsion doped with n-Cu for the rolling of strip steel was evaluated on a cold-rolling tester, which have four rolls. Results showed that when the rolling emulsion doped with oil-soluble n-Cu of 0.06% mass fraction, its anti-wear and extreme pressure properties could be improved, and the friction coefficient between steel/steel friction pair could be reduced. At the same time, the wetting performance of emulsion on strip surface was improved, also a good lubricity to the cold-rolled steel strips was obtained, which can make the minimum thickness of rolled strip steel obviously reduced and the quality of plate surface improved.
