Abstract
1403379 Arc furnaces ALLMANNA SVENSKA ELEKTRISKA AB 30 Nov 1972 [1 Dec 1971] 55270/72 Heading H5H [Also in Division F4] Charging tubes 18, 19 associated with electrodes 11, 12 and electrode arm 15, 16 have lifting lugs 22, 23 so that when the electrodes are withdrawn through the arched roof 14, the electrode arms engage the lugs and withdraw the charging tubes from the furnace or lift them from a position in which they are connetted to an opening 24, Fig. 3 (not shown), in the arched roof. A third electrode 17 and associated tube 20, Fig. 2, is used for three phase arrangements. Screens 25-27 are provided to protect adjacent table parts &c. of other electrodes from radiation of any one electrode which may be raised while others remain lowered. The lift may be hydraulic or electrical and the arched roof may be liftable or turnable. The furnace arrangement is tiltable as described in Specification 1,400,235.
