Method of obtaining a refractory mass based on electrofused zirconium for metal and alloy induction-melting furnaces

摘要

1. A method of obtaining a refractory pise based on zircon for lining induction turnaces for fusing metal, and alloys, particularly cast irons steels, copper ond copper alloys, nickel and cobalt, characterised in that the zircon is melted in an electric arc furnace, cooled rapidly, pulverised, screened and sized to a predetermined granulometric composition, and mounted by dry tamping without any additive, to form the crucible or tbe induction furnace.
