Abstract

1305237 Electromagnetic stirring ALLMANNA SVENSKA ELEKTRISKA AB 23 June 1970 [24 June 1969] 30297/70 Heading BIC In an electric furnace for non-ferrous metals the furnace bottom is supported by flat stirring coils 13 energized by a polyphase cement and themselves supported by the furnace base 15. As shown the coils are embedded in a ceramic compound 12 and have an iron core 15. In a modification (see Figs. 2 and 3, not shown) the core has poles (17) projecting upwards between the coils; the furnace is of ceramic compound with a sheet of stainless steel, the other walls being of carbon steel. The stirring currrent frequency may be 0.1-10 cycles/sec.
