Metal rolling involves passing metals between two rollers rotating in different directions to reduce the thickness of the metal. It converts metals into slabs, sheets, strips, or plates. The process and types employed depend on the desired end product. The processes of metal rolling include:
Ring rolling
Leads to the production of seamless rings of desired diameters. Rollers for larger rings feature a radial oriented that controls the height of the ring. The radial also maintains the alignment of the metal without axial growth. Examples of rolled rings are bearings, plane propelling turbine disks, and solid wheels in locomotives.
Roll bending
The diameter of the metal determines the bend. Lower and upper rollers press down on the workpiece, forming intrados and extrados. The design of the rolls is such that they fit the diameter of the workpiece to protect it from deforming. The process is repeated several times until the desired product measurements are attained.
Roll forming
Rollers are placed with precision repeatedly for incremental bending of the workpiece. The end product is a coiled material that often stays coiled. It is loaded into an uncoiler and fed through a flattener to remove the coil set.
Profile rolling
Profile rolling achieves a desired radius or diameter for a workpiece. Pressure in the roller expands the diameter of the metal. The materials are useful in constructions that require bending. All metal sizes can profile roll.
Steel, aluminum, copper, and brass are common rolling materials. Contact us at
