INDUCER FOR HEATING ROTARY PARTS Russian patent published in 2006 - IPC H05B6/36 

FIELD: engineering of devices for inductive heating; possible use in industry for thermal processing of rotary parts, including those of varying thickness, in particular, railroad and toothed wheels, disks and working wheels of turbo-machines and during tests of hardness and durability.

SUBSTANCE: in inducer for heating rotary parts, made in form of elongated loops with outputs, which envelope heated part from two sides, each loop has external inducing conductor, two asymmetric parts and zones of their mating in their end area, and also two internal inducing conductors, while internal inducing loop conductor is common for symmetric parts of loops and is bent along circle arc, radius of which is equal to external radius R_m of circular heating zone, and is mated with internal inducing conductors of two parts along arc of circle with certain relation of zones radius and mating of loops, and distance between loops mating zones, while internal inducing conductors are bent along curvilinear arcs also in accordance to certain relations.

EFFECT: increased efficiency and precision of inductive heating of rotary parts, for example, in shape of disk of varying thickness with given uneven distribution of temperatures in radial direction.
