PCT No. PCT/IT90/00053 Sec. 371 Date Mar. 14, 1991 Sec. 102(e) Date Mar. 14, 1991 PCT Filed May 17, 1990 PCT Pub. No. WO90/14742 PCT Pub. Date Nov. 29, 1990.An induction furnace is described which is capable to heat a thin strip from a continuous casting apparatus throughout the furnace itself after a previous rolling, at a homogeneous temperature adapted to the subsequent rolling steps. The induction furnace of the present invention comprises, in a known manner, an array of toroidal coils being fed at M.F., with intermediate feeding rollers having reduced size along the strip feed direction with respect to the known coils so that the rollers are less spaced from each other. Flux concentrators are also provided, being distributed preferably in pairs on the inductor and mounted transversely movable with respect to the strip forward movement and possibly also in a plane perpendicular thereto.
