FIELD: railway transport; car repair plants.
SUBSTANCE: proposed heater for inclined surface planes of overspring beams has base 1 on which multiple-turn ring inductance coil 4 is secured being connected to commercial frequency ac source, heat insulation, two movable U-shaped magnetic circuits 7 enclosing the coil in direction of magnetic flux diametrically arranged on base and provided with different-height posts. Low posts of magnetic circuits 7, whose end faces are machined at right angle to their axes, are pressed to overspring surface of beam, and high posts, whose ends are machined at angle of 45o to axes of magnetic circuit flanges, are pressed to inclined planes of overspring beam.
EFFECT: improved efficiency.
