Abstract

1392894 Crucible plugs ELEKTRO-THERMIT GmbH 8 June 1973 [22 June 1972] 27524/73 Heading F4B The outlet 5 of a crucible for hot liquid steel produced by aluminothermic reaction is closed by a tap pin 6 covered by a disc 1 of inorganic fibres, other than asbestos fibres, refractory sand 7 covering the disc. The fibres are composed of a mixture of alumina, silica, boria and an alkali.
