Abstract
The effects of process and material parameters on the coefficient of friction were investigated for an AISI 1018 low carbon steel and a Nb-treated HSLA steel grade. Samples with different scale thickness were rolled at various temperatures, reductions, and velocities in a laboratory rolling mill. Experimentally-measured roll separating forces, torques and the forward slip were simul-taneously matched to the calculated numbers using a finite-element code and the coefficientof friction wasthus determined.It is shown that the coefficient of friction increases with increasing reduction and decreasing temperature, decreasing velocity, and decreasing scale thickness.
