Two high rolling mill setup has been used to reduce the thickness of a plate from 40 mm at the maximum draft per pass to become 34 mm after the last pass. The width of the rolled material is 560 mm and the roll diameter is 560 mm. The material has a strength coefficient of 260 MPa and a strain hardening exponent of 0.18. The coefficient of friction during the process was 0.085. Determine the following: 1- Number of passes required to perform the reduction process = 2- Strain of the last pass = 3- Average flow stress of the last pass = MPa 4- The rolling force to roll the last pass =
0/ During the rolling process, the average flow stress is 20,000 lb/in², etermining the amount of reduction in the cross-sectional area (use n = 0.40 and K = 35,000 lb/in²).
