INDUCTOR FOR HEATING OF INTERNAL SURFACES OF THROUGH HOLES WITH DIAMETER OF 20-30 MM

摘要

FIELD: electricity.;SUBSTANCE: invention relates to devices for surface tempering and simultaneous heating, using currents of high frequency, in particular, to inductor design for heating to temper internal surfaces of through holes with diameter of 20…30 mm, height of 10…40 mm. The inductor comprises an inducting wire 1, current-supplying buses 2, tubes 3 for supply of cooling, a magnetic conductor 4, insulation 5.;EFFECT: possibility of heating holes of different parts on air.;5 dwg
