In some mills (e.g. hot strip mill, wire rod mill, merchant mill, and cold rolling mill), the rolled product is coiled in a coiler or a wind up reel. Mostly, rolling is done at high temperature, called hot rolling, because of requirement of large deformations. Hot rolling results in residual stress-free product.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 7.17 Reduction of Local Buckles. Even though the cold mill itself may cause local buckles, the majority of the local buckles are caused by the feed stock from the hot mill (Melfo et al., 2006). Therefore, proper monitoring of the hot band profile and mechanical properties will be the first choice to reduce local buckles.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Flat rolling of plates and sheets is essentially a plain-strain compression. f1.2. Roll Pass design for steel The cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls.
Answer: Steel rolling consists of passing the material, usually termed as rolling stock, between two rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise and the second anti-clockwise) and so spaced that the distance between them is …

– Hot rolling involves passing heated slabs of metal through rollers to reduce the size of the bar or slab. This process rolls a short thick product to create a longer thinner product. This process is performed at a hot rolling mill and is utilized on products that do not normally require exact tolerances.

In general, forging produces more hot work through the thickness of the bar that rolling will. At least, many will believe it does. Depending on the size of the bar, there are some rolled bars produced by continuous casting mills that may have very little rolling/forging reduction, which can have a negative effect on the mechanical properties.
