Rolling of Metals: Process and Principles (With Diagram)

The rolling process is shown in Fig. : Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

What is a Hot Rolled Steel?

09/04/2019 · Hot rolled steel is a type of steel that is formed using the hot rolling process at a temperature above its recrystallization temperature. Steel is easier to shape at this elevated temperature. Compared to cold rolled steel, hot rolled steel typically does not require any postforming heat treatment.

Rolling processes

Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required. Hotrolled metal is generally free of residual stresses, and its properties are isotropic ...

Roll Pass Design – IspatGuru

18/06/2014 · Hot rolling is a compression process. The roll force, which is the force imposed on the rolls by the processed metal during hot rolling, is an important design issue. Roll separation force and torque influence the whole process of roll pass design. The calculation of roll force is necessary to ensure that the mill is not overloaded and there is enough power available for the rolling reduction ...
