Abstract

1395656 Channel-type inductor furnaces ALLMANNA SVENSKA ELEKTRISKA AB 8 Sept 1972 [9 Sept 1971] 41776/72 Heading H5H [Also in Division F4] To prevent deposits being formed in the channel 12 leading to the hearth 14 of a channel inductor furnace, Fig. 1, a single gas nozzle comprising a semi-permeable gas plug 15 for introducing gas into the channel is positioned diametrically opposite the hearth 14. The channel 12 extends co-axially about the inductor primary coil 11 and is formed in the ceramic material 13. In use, inert and/or active gas (e.g. chlorine for treating melts containing aluminium, magnesium and the like metal), is fed to the single nozzle from respective supplies 16, 17. A double-inductor arrangement, e.g. Fig. 2, has two nozzles 18, 19 and three hearthconnecting channels 21-23, the nozzle positions being positioned as shown, In general, the invention requires that the number of inlets (nozzles) be one fewer than the number of hearth-connecting channels, in contradistinction to the prior art (Fig. 3, not shown), in which these members are equal.
