Abstract

1516710 Arc furnace ASEA AB 31 Oct 1975 [25 Nov 1974] 45203/75 Addition to 1501207 Heading H5M The hearth connection of the Parent Specification is modified by making the casing 8 frustoconical and providing it with cooling channels 9 on its external surface so that the terminal end 10 of electrode I will remain solid during operation and the position of the transistor zone 3 between molten and solid electrode material may be controlled.
