Question

Using the data provided in Table 1.1, calculate the roll force and the power for the case in which the workpiece material is 1 100-O aluminium and the roll radius, R, is 200 mm. Table 1.1 Mechanical properties for Aluminium 1100-0 Property Yield stress True strain True stress ( flow stress)110 MPa Value 55 MPa 0.223 (5 marks) APPENDIX FORMULA FOR CHAPTER 2 (ROLLING) Forward slip Forward slip V, Maximum draft . Roll force F = LWYang

Answer 1

For the given problem, i.e for rolling process we need to find the roll force and power for given process parameters. But here the strip width and speed are not provided in the question. However i selected some standard values for strip width and speed as 228 mm and 100 rpm. If you are having these, replace the same with yours value. Othervalues will temain same.
