Roll Design1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Backup 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).

To ensure proper tracking in a rolling mill, flat rolled coils are produced with a crown—the center of the strip is thicker than the edges. When slitting a coil, the thicker mults in the center rewind to a larger diameter than the thinner mults at the edges. Years ago slitting lines ran only in tightline mode.

Steel factory hot rolling mill problem definition. The function of the hot rolling mill is based upon the simple mechanism of using rolls to press steel slabs and reduce their thickness, as illustrated in Fig. 3. Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces.

The strip mill was a major innovation in steelmaking, with the first being erected at Ashland, Kentucky in 1923. This provided a continuous process, cutting out the need to pass the plates over the rolls and to double them, as in a pack the end the strip was cut with a guillotine shear or rolled into a coil. Early (hot rolling) strip mills did not produce strip suitable for tinplate ...

The finishing mills are composed of 5 to 7 consecutively arranged stands and coilers. Hot strip mills are named according to the length of the roll body, and those with a length of more than 914mm are called wideband steel mills. The length of the work roll of the finishing mill is 1700mm, which is called a 1700mm hot strip mill.
