Forging here covers all forming processes (e.g. rolling, extrusion, drawing, bending and die forging). In all hot forming processes, the workpiece is first heated to a high temperature to give high formability using only low forming forces, without strain hardening during the forming process, as happens with cold forming.
The applications are many (rolling of slabs, strips and tubes, extrusion of aluminum and copper alloys, drawing of sections, bending of large tubes, die forging of titanium and steel components).
Compared to furnace heating, the high heating rate in induction heating reduces oxidation and scale on the workpiece surface and thus also reduces the associated material losses. The essential requirements for heating here are precise temperature control, e.g. taper heating in isothermal extrusion moulding or a narrow temperature window in titanium forging (ELO-FORGE), and flexible adaptation to variable production conditions (ELO-FORGE, holding during press downtimes).
