Please well explained with answers, not just formulas. Two cold roughing (thickness reduction) operations are performed on a 25 in. wide, 6 ft. long plate of annealed AISI 1112 steel; The original thickness is 1.6 in. and is intended to be reduced inside a reversible mill to 1.1in. thick in two stages, each of the same value. The work rolls are 18 in. in diameter. n = 0.19, K = 760 Mpa, RPM = 250 What is the coefficient of friction required to perform this work? What is the power required for the second roughing performed? Estimate the yield stress of the 1.1 in material.
