Abstract : Earlier papers dealing with friction in cold rolling have failed to take into account the role of the temperature factor, although the temperature of the metal sometimes rises to 250 to 300 degrees C, which drastically affects the properties of lubricants. This study discusses the effect of the metal's temperature on the friction factor in cold rolling within 20 to 250 degrees C. The lubricants were castor and spindle oils. The experiment involved specimens of 08 KP work hardened steel rolled on a DUO mill on hardened steel rolls 191.1 mm in diameter at a reduction in area of 10 percent. (Author)
