Abstract

1374515 Pressure furnaces ALLMANNA SVENSKA ELEKTRISKA AB 14 March 1972 [15 March 1971] 11740/72 Heading F4B An elongate pressure furnace for treating material at high pressure (> 100 bars) and high temperature (1500‹ C.), comprises a pressure chamber 1 formed of a steel tube 2 and a wire mantle 3, and a furnace 6 having electrical heating elements 8 and an annular insulating mantle 9. The mantle 9 is constructed of metal foil having a thickness of from 0À01 to 0À1 mm., usually in the form of truncated cones 12 threaded on to a tubular frame 13 and welded to the frame along the upper edge of the cones. Narrow gas-filled spaces 14 are formed between the elements 12 in other embodiments, the metal foil may be in strip form and wound helically around the tubular frame or in spiral form, the various layers being spaced from one another by means of narrow metal strips (17, Fig. 7).
