Abstract

533,747. Electric induction furnaces. ELECTRIC FURNACE CO., Ltd., and HOWARD, J. C. Nov. 21, 1939, No. 30471. [Class 39 (iii)] In an induction furnace having passages of relatively small cross-section through which the molten metal circulates from a main interior space, the refractory walls of the passages are surrounded by a non-oxidizing atmosphere such as nitrogen or other inert gas.
