Hot rolling quantity

Apr 01, 2021

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

    Hot rolling. Semi-finished products are re-heated to 1,200 C. This is above steel’s recrystallisation temperature, making it easier to form, but less suitable for precision applications like car bodies. Before it is rolled, scale is removed and the steel is cooled. During the flat steel hot rolling process, the steel thickness can be reduced
