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.

The Two Roll Principal. The Two Roll Principle method is comprised of a steel top roll and a urethane bottom roll. A segment of this top roll is pushed into the urethane bottom roll, and this deflecting volume of urethane functions the same as hydraulic fluid in a hydroforming process, exerting very high pressures against the steel roll.
