Profile rolling

Rolling process in which the workpiece passes through a series of rollers that gradually shapes the workpiece into the required profile.

The process

The work piece [1], typically a raw bar, is first fed through a pair of rollers [2] to form a coarse beam. The beam is then passed on through multipurpose roller pairs [3] that have both horizontal and vertical rolls that are adjusted according to the desired profile. An edge roller [4] ensures that the upper and lower surfaces of the beam are parallel. The beam goes at last through another multipurpose roller pairs [5] which pushes out the final profile.
