The thickness of a steel plate with material strength coefficient of 210 MPa, has to be reduced from 20 mm to 15 mm in a single pass in a two-high rolling mill with a roll radius of 450 mm and rolling velocity of 28 m/min. If the plate has a width of 200mm and its strain hardening exponent. n is 0.25, the rolling force required for the operation is_____kN (round off to 2 decimal places) Note: Average Flow Stress = Material StrengthCoefficient×(Truestrain)n(1+n)1167.26 |
