摘　　要：选用合适的基础油与油性剂、抗氧剂、极压抗磨剂和防锈剂等功能添加剂,利用亲油亲水平衡体系调节乳化油的乳化状态制备不同颗粒度分布的冷轧乳化液;通过MS-10A杠杆式摩擦试验机考察颗粒度与乳化液极压、抗磨性能的关系;借助实验用四辊可逆冷轧机组,对比分析不同颗粒度分布的乳化液润滑下轧后的板面质量。实验结果表明,乳化液的颗粒度分布与其稳定性和润滑性能存在一定的对应关系;在一定体积平均粒径范围内,随着颗粒度的增大有利于提高乳化液的抗磨减摩性能,改善冷轧成品板面质量。Through selecting suitable base oils and oily agent, antioxidant, extreme-pressure anti-wear additives and rust inhibitors, and other function additives, the cold rolling emulsions of different particle size distribution were prepared by using the oil-water balance system to regulate the emulsion state. The relationship of the emulsion particle size and the extreme pressure and anti-wear properties was investigated on the MS-10A lever-type friction testing machine. The quality of plate surface after cold roiling by the emulsions of different particle size distribution was studied and compared by using the four-high reversing cold rolling mill. Experimental results show that the particle size distribution is related with the sta- bility and lubricity of the emulsions, and in a certain range of volume average diameter, as the particle size of emulsion in- creases, the anti-wear and friction reducing properties of emulsions are improved, and better surface quality of cold-rolled products can be achieved.
