CONTINOUSLY OPERATING, DIRECT INDUCTION RESISTANCE HEAT TREATMENT PROCESS AND EQUIPMENT FOR HEAT TRETMENT OF PLATE BAND AND FOIL AND WIRE ROLLS MADE FROM METALL AND METALL MOULD

摘要

The equipment re-coils the material to be treated (5), forming a closed loop which acts as the short circuited, low voltage sec. winding of the heating transformer (1). The method is energy saving, provides fast and uniform heating of the material along its cross-section and length and controllable, allowing the creation of ideal heat treatment conditions.
