Include the slabbing mill, hot roll mills, cold roll mills, single reduction mills, and double reduction mills.2.Any operating unit that reduces gauge by application of loads through revolving cylindrical rolls operation can be hot or cold.The elevated temperature rolling mill is the hot mill and is capable of reducing the gauge of a slab.
Finishing rolling mill for cold rolled strip is preceded and followed by pairs of traction rollers which are partly encircled by the strip in an s-shaped loop.The rollers are arranged on top of each other and to run the strip into the gap between them the lower roller can be swung out of the way to above the top roller, preferably around the axis of the top roller as pivot.
Is then transferred to the work rolls by conduction.In a hot mill, with product temperatures between 820c1500f and 1100c2000f, heat is also transferred to the work rolls in the area adjacent to the roll gap by radiation.Since product temperature is assumed to be uniform, and the deformation and.

The back up rolls act as a heat sink because there is a considerable amount of heat energy going into the strip and the work roll.Much of the heat in the work roll is transferred to the back up roll.Having a large diameter back up roll allows the mill to run at high rates of speed compared to an old 20-high mill.
A modular rolling mill comprises a plurality of separate rolling units arranged along a mill pass line.Each rolling unit includes at least two pairs of work rolls defining oval and round roll passes and carried on roll shafts that are staggered 90 with respect to each other.The rolling units contain intermediate drive trains configured to connect the roll shafts to parallel input shafts.
