Aug 01 1991 · Refractory melting in an induction furnace is abnormal but unfortunately not uncommon. It is not a normal erosion mechanism but rather is a consequence of buildup clogging or bridging. Entrapped metal in a high-energy induction field can easily reach the failure temperature (melting point) of the refractory material.
