Abstract

550,732. Distilling metals; magnesium. KEEMLE, S. R. Sept. 19, 1941, No. 12154. Convention date, Sept. 23, 1940. [Class 82 (i)] [Also in Group XI] An electric furnace suitable for the production and distillation of magnesium and other volatile metals comprises a furnace chamber 1 with refractory lining 4 having three radiating electrodes 5 of graphite within water jackets 6. Each electrode is hollow and contains a screw conveyer 7 for injecting fine coke. A neutral electrode 8 is supported on a stem 9 which is non- rotatable but can be reciprocated to tamp the coke in the furnace. A casing 21 is surmounted by a casting 22 having passages for cooling water connected to pipes 24, 25 and ring pipes 26. Gearing 29 is provided to rotate or oscillate the casing 21. The upper end of the casing is surrounded by an ash column housing 30 surmounted by a water-cooled ring 31. The casing 21 and electrode 8 are reciprocated vertically by a hand or power operated lever 34. Three radial water-cooled conveyers 10 are spaced between the electrodes 5 and at a higher level, and inject a mixture of calcined dolomite and coke. Coke is also supplied through a hopper 14 and chamber 13 under control of a closure member 16. Magnesium vapour passes through passage 36 to a nozzle 39 in a condenser 40 containing petroleum tar. Petroleum tar is sprayed upward from a nozzle 41 to condense the magnesium and gases pass out through pipe 42 to a fractionating tower. In operation, lime is fed through conveyers 10 to form three piles, and fine coke is fed through the electrodes 5 to fill the intermediate spaces. Coarse coke is fed from the hopper 14 to cover the fine coke and lime. Carbon monoxide is injected at several points 43 to prevent burning of the coke, until a temperature of 1800‹C. has reached the spray 41, and is then replaced by hydrogen. A mixture of ore and coke is then fed through conveyers 10, and a mixture of carbon monoxide and magnesium vapour passes to the condenser. Magnesium is there condensed and coated with petroleum tar, which is drawn off from the pool and distilled. Tin or lead may be sprayed instead of petroleum tar, in which case an alloy is obtained. The furnace may be modified for single phase current by substituting a single electrode in the passage 18. An alternative three-phase furnace is described. Figs. 3 and 4 (not shown), in which the central electrode and conveyers 10 are omitted, and the mixture of ore and coke is fed by a conveyer within the opening 18. The lime is placed in position in three heaps between the electrodes before the furnace is assembled. Specifications 381,115, 431,537, and 448,536 are referred to.
