Rolling Mill - an overview | ScienceDirect Topics

J.F. Cameron, C.G. Clayton, in Radioisotope Instruments, 1971 Cold-strip reduction mills. A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten.. It has long been recognized that some, if not most, of the variations in thickness of strip produced
