Abstract

922,714. Heating metal strip by electromagnetic induction. DEUTSCHE EDELSTAHLWERKE A.G., and ALLGEMEINE ELEKTRICITATS-GESELLSCHAFT. Aug. 7, 1959 [Aug. 9, 1958], No. 27034/59. Class 39 (3). In a method of progressively inductively heating metal strip of a thickness less than 0.5 mm., e.g. 0.1 to 0.35 mm., the strip 18 is first inductively heated to a temperature somewhat below that required by means of a medium frequency current, e.g. between 5,000 and 10,000 c.p.s., passing through coils 17, and is then rapidly heated to the required temperature by means of a higher frequency current, e.g. more than 10,000 c.p.s., passing through coil 17<SP>1</SP>. The frequency of the current in coil 17<SP>1</SP> is preferably twice that used in coils 17. This heating method may be used for drying films of varnishes applied to a metal strip, for annealing or tempering or homogenizing the strip, or for flowing electro-deposited layers of tin on the surface of low carbon steel strip. The coils 17 may be supplied in parallel from a bus-bar with current generated in a rotary converter while coil 17<SP>1</SP> is connected to the busbar through static or rotary frequency changers. As shown, the strip is finally immersed in a quenching bath 22.
