CONTINUOUS ACTION PLANT FOR SYMMETRICAL INDUCTION HEATING OF BALL-SHAPED ITEMS Russian patent published in 2011 - IPC C21D9/36 H05B6/36 

FIELD: metallurgy.

SUBSTANCE: continuous action plant for symmetrical induction heating of ball-shaped items includes metering hopper equipped with mechanism of its movement in horizontal and vertical planes, hopper feeder of discrete action, feed chute from feeder to inductor, which is equipped with hinged and telescopic articulations, inductive wire wound about the guide channel bent in the form of helix with vertical symmetry axis; at that, inductive wire is wound about the guide channel of annular or semi-annular section bent as shaped spiral with variable curvature of turns, inscribed into the surface of one-sheet hyperboloid or the surface of the second order, which is similar to it.

EFFECT: elimination of sliding and rotation of balls at rolling down along spiral guide channel.
