摘　　要：采用摩擦磨损试验机研究了两种轧制油的摩擦学特性。采用三维形貌显微镜检测了镀锡基板的表面微观形貌。根据镀锡基板表面微观形貌确定了辊缝内的摩擦状态。结合冷轧辊缝润滑系统分析了镀锡基板表面微观形貌的演变。结果表明:1号轧制油高温润滑性优良,其40℃的运动黏度为46.5 mm^(2)/s,黏度指数为169,225℃的油膜强度为804 N,225℃的平均摩擦因数为0.078;采用1号轧制油使MR T-4钢板表面划伤的月平均发生率降低了4.44%,MR T-5钢板表面条纹的月平均发生率降低了11%。Tribological properties of two rolling oils were investigated by a friction-wear testing machine. Microscopic pattern of surface of the tin mill black plate was detected via a three-dimensional morphology microscope. Friction state in roll gap was determined according to the microscopic pattern of surface of the tin mill black plate. Coupled with the lubrication system of cold-roll gap, the evolution of microscopic pattern of surface of the tin mill black plate was analyzed. The results showed that(a) the rolling oil No.1 exhibited good lubricity at high temperature, kinematic viscosity of 46.5 mm^(2)/s at 40 ℃, viscosity index of 169, oil film strength of 804 N at 225 ℃, and average friction coefficient of 0.078 at 225 ℃;and(b) the use of rolling oil No.1 caused the mean incidence of scratches per month on MR T-4 steel sheet to reduce by 4.44%, and the mean incidence of streaks per month on MR T-5 steel sheet to reduce by 11%.
