    摘要： A crucible furnace comprises an enclosure having an outer casing 20 internally lined with thermally insulating material 21 surrounding but spaced from a crucible 22 so as to define a circular flow path 23 around the crucible. A gas fuelled reversing burner system is provided having two burners 24 and 25 each with an associated heat regenerator 42. The burners 24,25 are operable alternately as firing burners and as flues. When one burner, say burner 24, is firing, the hot combustion product gases from that burner flow in one direction along the flow path 23 and around the crucible 22 and leave the flow path through the burner 25 in flueing mode, whilst in the alternate cycle the hot combustion product gases from the firing burner 25 flow in the opposite direction along the flow path 23 and leave the flow path through the burner 24 in flueing mode.

    摘要： A holding furnace for molten metal comprises an inner vessel (32) formed of flat, rigid, heat-resistant panels (37, 40, 41). The panels are held in sealing engagement with one another at abutting edge surfaces (42A, 42B, 43) by the action of inwardly directed pressure applied to the panels by an integrally cast refractory outer vessel (34) through the intermediary of a resilient layer (33) of heat-resistant fibrous material. The pressure is applied as a result of the shrinking the casting compound undergoes during the setting. When the inner vessel (32) is being made, the panels (37, 40, 41 to which the resilient layer (33) has initially been applied, are held together by the action of a reduced pressure in the inner vessel (32) as the latter is positioned in a furnace casing (36) interiorly lined with a mineral wool insulation (35). The inner vessel (32) then is cast around with a refractory casting compound for forming the outer vessel (34).
