Abstract: To fast load a metal alloy casting furnace 1 at a high casting temperature to supply foundry molds at an industrial pace, a liquid portion of the overall load is first introduced deep inside the furnace with a device L comprising a telescopic channel 30-31. A solid portion of the remaining overall load is then introduced with a device S comprising a tilting pusher-equipped channel 20 disposed below a static hopper 15. The liquid part of the load includes alloy compounds which are the least sensitive to oxidation; the solid part includes compounds which are highly sensitive to oxidation.

Abstract: A fusing furnace casting channel 13 is surrounded by an induction heating coil 17 embedded in a refractory lining 12. A graphite sleeve 20 having a refractory inner coating 16 defines the casting channel. The sleeve serves as a permanent, single turn secondary winding such that the channel may be preheated even when no molten metal is present in the channel, which would ordinarily act as the secondary winding or core. This enables the casting channel to be maintained at a high temperature between successive casting operations.
