Rotational Induction Heating

Induction heating of cylindrical billets of nonmagnetic metals like aluminum before their extrusion or hot forming is a widely spread technology used in many industrial plants. One of alternative way of induction heating of non-magnetic cylindrical billets. Basic device for rotational induction heating consists of an induction motor driving the billet and an active heating part. A rotating billet is heated in static magnetic field generated by high-parameter permanents magnets fixed on magnetic circuit.
