a. What do you understand by rolling operation. Discuss the grain deformation in rolling operation with suitable schematics. [3] b. A 30 mm thick plate with plate width 100 mm is reduced to 26 mm by performing a single pass rolling operation. The roller radius is 200 mm and the speed of the strip at the exit is 30 m/min. The average true stress for the plate material is 300 MPa. Calculate the roll force and the power required in this operation. [3] a. What do you understand by rolling operation.
