Abstract
<PICT:0999268/C6-C7/1> <PICT:0999268/C6-C7/2> In vacuum degassing apparatus of the type consisting of a chamber having a downwardly extending inlet and an outlet pipe, the latter is initially closed by means of a tapering metal cap attached to its end, a packing being provided between the cap and the end of the pipe to prevent the ingress of slag. The packing is preferably of a fibrous material such as mineral or steel wool. In a preferred embodiment the metal cap is covered with a substance such as cardboard which evolves gas on contact with the slag layer, while a wooden plug is inserted in an opening in the apex of the cap. Premature burning of the wood and cardboard may be prevented by a coating of aluminium bronze paint. As shown in Fig. 2, cap 2 is attached to pipe 1 by means of wire holders 8 and eyes 7 welded to pipe 1, an annular packing 9 being placed between the cap and the pipe. In the modification of Fig. 5 the packing is located by means of a tube 11 coaxial with pipe 1, the tube being of such a length that the distance between the upper end 12 of the tube and the apex 13 of the cap is greater than the depth of the slag layer. If a sufficiently close fit in pipe 1, tube 11 may form a means of attachment for cap 2.
