Cold Rolling: The tubing is rolled through mills for elongation and thinning. The rolling of the steel mills applies pressure on the steel tube. The cold rolling is usually conducted at room temperature. Cold Drawing: The tubing gets drawn through a die, with or without a mandrel. The pressure is applied locally as the tubing gets drawn through ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its crosssectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
