Hr Mills Rolls ( hot rolling )

Hot rolling is a metalworking process that involves heating steel to temperatures above its recrystallization point, usually over 1000° F, and passing it through rolling mills machinery. This process makes the steel more malleable, which allows it to be shaped and formed into different forms and thicknesses. The grains deform during processing, then recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening.
