A system for evaluating the lubricity of newly developed rolling oil is constructed when it is used in an actual cold rolling mill. In the system, the evaluation is carried out as follows ; (1) Coefficients of friction and limitation lines of conventional oil and developed oil are measured by means of the simulation testing machine. (2) The interfacial temperature rises due to friction between roll and workpiece of the two oils are calculated. (3) The pass schedule in the actual mill is examined. (4) The interfacial temperature rise at the stand in which the fricition pick up occured is calculated from the data examined. (5) When the developed oil is used in the actual mill, the interfacial temperature rise at the same stand is calculated. (6) From these results, the maximum rolling speed in the actual mill is calculated when the developed oil is used. By means of this evaluating system, the maximum rolling speed when the newly developed oil was used in the actual mill increased by 200m/min compared with that of the conventional oil. It is seen that the evaluating system is effective to develop the new oil.
