DEVICE FOR HEATING OF RAIL SECTION TO BE RECOVERED IN TRACK BEFORE ARC WELDING DEPOSITION

摘要

FIELD: electricity.SUBSTANCE: loop inductor elongated in longitudinal direction includes similar and opposite to each other plate longitudinal elements with evenly turned-up upper sections and flat lower sections located from each other at a distance which provides slide or medium fit at installation of the inductor along edges of rail head matching them. The first end parts of inductor longitudinal elements are interconnected by plate cross element which face and back surfaces have shape corresponding to the shape of central part of rail roller surface of a new rail. The second end part of each longitudinal component is equipped with plate cross half-element having shape that corresponds to the shape of respective rail roller surface of a new rail. Each cross element is equipped with current lead connected to the respective output lead of the matching unit.EFFECT: invention provides even heating of a rail head both at roller face and from side edges; it also has high efficiency of electric energy conversion into thermal energy notwithstanding depth of deposition area.7 cl, 6 dwg
