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 by a cold-reduction mill have their ...

Hot Strip Mill. The Hot Strip Mill is where CSI's rolling operations begin, as steel slab is reheated and rolled to hot rolled coil. With an annual capacity of more than two million tons, the rolling mill is more than a half-mile long and includes a walking beam reheat furnace, a two-high scalebreaker, five four-high roughers, a crop shear, six four-high finish mills, and two downcoilers.

The W 50 DC rumbler is a standard W 50 DC cold milling machine with an optional rumbler attachment installed. The rumbler attachment permits high-production cutting of milled rumble strips in the standard, preferred 16-in. width at speeds of up to 180 fpm. The Wirtgen rumble strip milling attachment makes the W 50 DC even more valuable to an owner.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).

The numbers, and sometimes letters, following this prefix describe the mill's geometry, the relative size of its work roll, and the widest strip that the mill can roll. The number immediately following the "ZR" indicates the mill "section" size comprising a combination .
