What is Hot Rolling Definition from Corrosionpedia

What Is Hot Rolling Definition From Corrosionpedia

Sep 30, 2020 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. The hot metal is passed between two rolls to flatten it, lengthen it, reduce

Difference Between Hot and Cold Rolled Steel Metal

Difference Between Hot And Cold Rolled Steel Metal

Sep 11, 2014 Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700 F), which is above the steels recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
