摘　　要：通过复配与筛选合适的基础油,选择相应表面活性剂、防锈剂、消泡剂等添加剂,并在超声波作用下添加平均粒径为20nm、经油酸修饰的纳米Fe_3O_4微粒,研制出适用于板带钢冷轧所需的新型轧制液;在MRS-10A四球摩擦磨损试验机上考察了轧制液对钢。钢摩擦副摩擦磨损性能的影响,采用光学显微镜观察了磨损表面形貌。利用二辊冷轧试验机进行了轧制液润滑下的板带钢冷轧试验,并与传统轧制液进行对比。结果表明,由于纳米微粒的使用,轧制液能更好地改善钢-钢摩擦副的抗磨性能、降低摩擦系数;同时还表现出良好的板带钢冷轧润滑效果,可明显降低带钢轧制过程中的轧制压力、轧机功率等轧制力能参数,并能有效改善轧制带钢板面质量。In the presence of ultrasonic, Fe3O4 nano-particles having an average particle size of 20 nm and modified with oleic acid, were dispersed in an emulsion, which was a selected base oil compounded with appropriate additives, such as surfactants, rust inhibitors and defoamers. The tribological properties of the newly developed cold-rolling emulsion containing nano-Fe3O4 were evaluated using MRS-10A four-ball test machine. The worn surfaces of the steel balls were investigated by optical microscope. Besides, the lubricity of this cold-rolling emulsion was evaluated on a cold-rolling tester using conventional emulsion as reference. Results indicate that Fe3O4 nano-particles as additive in cold-rolling emulsion could significantly improve the friction-reducing, anti-wear and surface quality of the friction pair. The new emulsion containing nano-Fe3O4 shows good lubricity performance during cold-rolling steel strips, the surface quality of the rolled strip is improved, and at the same time, the rolling force and energy parameters are decreased.
