Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
In addition to examples with the common 4-high vertical stand rolling mill, application of the presented method to the most complex of rolling mill configurations is demonstrated with an optimization example involving the 20-high Sendzimir mill.

Steel Hot Rolling Mill Application Overview Temperature Control in the Hot Rolling Mill The Hot Rolling Mill is used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape (rails and H-beams).
The idea of introducing a direct application rolling oil system and oil to the 5-stand cold mill that was originally designed with a recirculating oil system was driven by the need to maximize through-put. The novel idea was embraced because direct application of oil by itself was not foreign to multi-stand cold rolling mills.

Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 220.127.116.11 Plane-Strain Flow. The flat rolling process is usually taken to be essentially two-dimensional in the sense that the width of the product does not change much during the pass when compared to thickness and length changes and this makes the assumption of plane-strain plastic flow 5 quite realistic.
the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills, in a wide range of types and sizes are available; some are single stand, others 3 stand and some 5 stand (Figures 1301.02.03 and 1301.02.04).
