Friction Coefficient's Numerical Determination for Hot ...
Oct 05, 2015· In this paper, a nonlinear quadratic expression of the coefficient of friction at both entry and exit sides have been derived from the equations of rolling load in Hot Rolling Bland and Ford's program (HRBF). The study developed a numerical model for the estimation of coefficient of friction for steel (HC SS316) of different thicknesses on two high reversing mills.
