A 200 mm wide and 42.0 mm thick plate made of low carbon steel is to be reduced in one pass in a rolling operation. As the thickness is reduced, the plate widens by 4%. The entrance speed of the plate is 15.0 m/min. The roll radius is 325 mm and the rotational speed is 49.0 rev/min. i. If the current horsepower of the available rolling machine is 950 HP, how much thickness could the machine reduce the plate thickness to? ii. If the required thickness needs to be 34.0mm, how could the original width of the plate be changed in order to use the same machine?

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. CW=13% or .13 What is the plate thickness (mm) prior to the last rolls, t1, if the last set of rollers perform cold work reduction listed below at .13 or 13% Note that 9.52 mm is equal to 3/8 of an inch.
