Abstract

1448954 Crucible furnaces ALLMANNA SVENSKA ELEKTRISKA AB 15 Jan 1974 [16 Jan 1973] 01773/74 Heading F4B A crucible furnace has a coil 11 with a surrounding magnetic yoke 12 and a lining 13 that can be removed substantially in one piece through the lower end of the coil and yoke when the bottom 14 of the furnace is removed. The furnace is placed over a container with dust shields 18 and 17 positioned as in Fig. 3 and the lining 13 is then pushed or allowed to fall into the container. The coil 11 may be clamped axially by a projecting member (30) on the iron core 12 and by flanges (19) and (20), Fig. 6 (not shown), so that it does not become loose when the bottom 14 is removed.
