Rolling (metalworking) - Wikipedia

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.

Difference between Hot Working and Cold

The material may start out quite cold, even as low as 32 F (0 C), but when it comes out of the cold mill, it will be far too hot to touch. This is not because heat has been applied by flame or conduction, but simply because of the massive amount of working done in the rolling process.

What Is Cold Working or Work Hardening? -

Cold rolling is the most common method of work hardening. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. As it moves through the rollers and is compressed, the metal grains are deformed. Examples of cold-rolled products include steel sheets, strips, bars, and rods.

Cold Rolling - eFunda

Introduction: Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed. The amount of strain introduced determines the hardness and other material properties of the finished product. The advantages of cold rolling are good dimensional accuracy and surface finish.
