Document Type and Number:
Japanese Patent JPH0380578
Kind Code:
B2
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.
