The effect of roll material on lubrication characteristics is examined by using cemented carbide rolls with different carbide contents for the purpose of improving productivity in cold sheet rolling. Coefficients of friction for reduction in thickness and limit reductions of friction pick up are measured by means of the simulation testing machine of slidingrolling type. The effects of roll material and surface roughness on the coefficients of friction are quantitatively evaluated. On the other hand, the limit reductions are evaluated by both carbide area and carbide mean spacing. The results obtained are as follows; (1) The coefficient of friction is influenced more considerably by the surface topography of the roll than by the roll material. (2) The cemented carbide rolls have good anti-seizure property due to their carbide mean spacing. (3) If the cemented carbide roll should be applied to the actual mill, the maximum rolling speed would probably be two times faster than that of a 5%Cr-steel roll.
