Rolling of sheet metal.
The degree of metal deformation is determined only by the ratio of roll speeds, not by their position.
By adjusting the pressure level, the properties of the rolled product can be changed.
The process ensures specified and uniform properties along the entire length of the strip.
The rolling-drawing process is used to clean hot-rolled strip from scale.
The process promotes its mechanical destruction.
