Abstract

831,399. Electric furnaces. SOUDURE ELECTRIQUE AUTOGENE SOC. ANON. PROCEDES ARCOS. March 6, 1958 [March 21, 1957], No. 7258/58. Class 39(3) [Also in Group XXXV] The rate of fall of a vein of a molten metal in a tube of refractory material, e.g. iron or steel being delivered from a crucible 9 to a mould or rolling mill, is controlled by a travelling magnetic field produced by polyphase excited cores on either side of the tube (see Group XXXV). The windings may be energized at frequencies above mains frequency, e.g. 500-1000 c.p.s. in the appropriate phase-sequence to retard or accelerate the gravity flow. The thermal gradient in the tube 2 may be reduced by electric preheating of the envelope 11 from a source 28, air circulation being prevented by a temporary metal plate 29. The interior of the tube 2 may be heated by a U-shaped graphite resistor 35, 37 which is lowered into the tube and withdrawn before metal is allowed to pass into the tube. Alternatively, where the frequency is high enough, the tube may be preheated by introducing a steel rod which gradually heats up due to induced currents, and finally melts.
