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 Pickling Process CSI's pickling line started up in late 1994, and typically processes two out of every three coils produced at the Hot Mill.
Understanding Rolling Process in Long Product Rolling Mill. ... the hot rolling stock heats the roll due to conduction during the contact time with the roll. As a result, the temperature profile on the surface of the roll increases when in contact with the roll and then drops as the heat is absorbed by the roll body. ... The goal of mill and ...

Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal.
