Question 46
MENAT2 marksNeeds review
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 roll mill with a roll radius of 450 mm and rolling velocity of 28 m/min. If the plate has a width of 200 mm 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 Strength Coefficient × (True Strain)^n/(1+n)
