Class problem/example continued: A strip 300 mm wide and 25 mm thick is rolled to a final thickness of 21 mm with mm rolls running at 60 RPM. K = 275 MPa and n=0. 2. Using two passes of draft = 2 mm (i. e. h1=23 mm and h2=21 mm), the class found that the rolling forces were 1076 and 1403 kN respectively, and that the power requirement was 197. 16 kW. It is hypothesized that since the flow stress is higher for the 2nd pass, the power requirement would be reduced by taking the first pass at the maximum draft of 2. 5 mm (i. e. , h1=22. 5 mm and h2=21 mm). Compute the rolling forces and the power requirement for this modification of the process. Friction may be neglected in the force calculations.
