How does cold rolling work
WebFeb 10, 2024 · Cold rolling is the primary process used for cold forming metal. It involves introducing strip or coil stock between two rollers that apply constant pressure to compress the metal into a thinner sheet. Altering hardness and other material properties is possible by varying the amount of strain applied to the workpiece. WebFeb 6, 2024 · Mechanical working or cold working is done to change the shape or dimensions of metal, without changing its temperature. This is achieved by applying force to the metal in some fashion, thus inducing plastic deformation. Cold working can be done by rolling, hammering, drawing, extruding etc. How Cold Working insert residual stresses?
