Abstract
Dual electric/gas heating in a crucible melting furnace with segmental lining, and lining and segments of linings for same, are disclosed.
Claims8
A refractory lining for a radiant heating furnace comprising a plurality of lining segments or panels shaped to abut to form a radiant heating enclosure for a metal melting crucible while being individually withdrawable in the event of failure, the segments having a surface configured to absorb and reradiate to the crucible heat from combustion gases passed over the lining in use, and at least one of the segments being provided with electrical heating elements below said surface of the segment.
