Abstract

1,136,529. Induction crucible furnaces. BROWN BOVERI & CO. Ltd. 30 Nov., 1967 [2 Dec., 1966], No. 54581/67. Heading H5H. An induction crucible furnace, of the type comprising a rammed crucible 1 surrounded by an induction coil 2, includes a ceramic cylinder 3 with longitudinal drain holes or passages 5 which are open on the crucible side of the cylinder along at least part of their length, a water-tight and mechanically robust outer layer 6 and a layer 7 of thermally insulating and water-permeable material, e.g. asbestos, which prevents clogging of the water-draining passages 5 by the rammed crucible composition 1. The cylinder 3 is assembled from segment - shaped ceramic plates 4 with longitudinal passages 5 open throughout their length towards the crucible 1, (Fig. 3, not shown), or with longitudinal passages 5 open towards the crucible through slots (9) distributed uniformly along their length, (Fig. 4, not shown). Water issuing from the rammed composition drains freely via passages 5 and a furnace may thus be operated at full voltage with a new crucible immediately.
