The SRV (Schwingungs Reibung und Verschleiss ) test machine is widely used to measure the coefficient of friction of various lubricants, especially the coefficient of friction of the engine oil, and the testing temperature is usually below 300°C. In the conventional method, the coefficient of friction depends on the heating time and the heating temperature at higher temperature. A new method is developed to measure the coefficient of friction for hot rolling oils which are operated above the temperature of 300°C. A series of experimental tests are carried out in order to evaluate the new method. In the new method, the coefficient of friction of base oils at higher temperature can be stably measured and the effect of the additive agents on the coefficient of friction can be evaluated. Moreover, the difference between the coefficients of friction of the commercial hot rolling oils can be evaluated by the new method. hot rolling, mechanical testing, lubrication, coefficient of friction, evaluating method.
