  • Railless support of billets within electric induction heating coils
    Patent number: 10904954
    Abstract: A railless billet electric induction heating apparatus and method is provided where billets are continuously or statically heated by induction by moving the billets without billet support rails through an induction coil supplied with alternating current power when the billets are in direct sliding contact with the interior surface of a clay graphite billet slider disposed within the induction coil. The clay graphite billet slider can also provide thermal insulation between the induction coil and the clay graphite billet slider to eliminate the requirement for a separate induction coil refractory.
