Walk-Through Video Dashboard Note: - You are attempting question 4 out of 12 In a rolling operation, a plate of 2 cm thick and 25 cm wide is passed through a rolling mill having 2 powered rolls. Assume friction was enough for rolling. Thickness of the plate at the end of operation is 1.7 cm. Each roll has a radius of 0.3 m and a roll speed of 0.5 revolution per second. Flow curve has the following values K = 225 MPa and n = 0.15. Determine the power required for driving the rolls.
A hot/cold rolling setup is shown right. The operation first hot rolls a 3/8” thick plate, 12” wide (w), of6061 Aluminum, to an intermediate thickness, then finally through cold rolling, down to 1/4” thick plate.The friction factor μ is assumed to be constant at 0.15 for the hot roll, 0.12 for the cold rolling stage. Thefirst set of rolls operate at 50 RPM. Also ignore any width increase during rolling.
