  • Refractory Selection Guide for Secondary Aluminium Smelting

    Apr 28 2011 · Refractory Selection Guide for Secondary Aluminium Smelting. Secondary aluminium smelting differs from primary smelting in that it uses recycled aluminium from scrap rather than refining it from ore. Producing one ton of aluminium from scrap uses about 5 of the energy of that required to produce it from bauxite.

  • Controlling refractory erosion in induction furnaces the

    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.
