Abstract (en)
[origin: WO8603646A1] A railroad rail head inductor (10) raises the temperature of the top and sides of the head (52) to austenizing temperatures without inducing thermal strains which generate horizontal kinks along the sides of the head. The inductor (10) has an electrical conductor (30) for carry alternating current across the top and along the lateral sides of the rail head (52) for concurrently inducing a magnetic flux in the top and sides of the rail head (52). Laminations of electrical steel (40) about the conductor are disposed on both sides of the rail for concentrating the magnetic flux induced in the lateral sides of the rail head (52). Laminations (41) may be provided about the conductor (30) over the rail head (52) for concentrating the magnetic flux concurrently induced in the top of the rail head (52).
