This 60-inch, five-stand, Blaw Knox cold rolling finishing mill can operate at mile-a-minute speeds. Sheet previously hot rolled to a thickness of one-eighth inch is precision rolled by this equipment to .008 to .016 inch in thickness. Photo shows the entry end of the mill, one of two computer-controlled cold mills at Alcoa’s Warrick Operations, near Evansville, Indiana. This unit produces finished sheet 48 inches wide. The other turns out 36-inch wide close tolerance, high quality sheet for volume use.
