FIELD: heating system.
SUBSTANCE: invention involves determination of the tank material type and selection of a suitable voltage variation curve for this material, for use in the thermal treatment process in induction heat treatment equipment. The tank material type is determined from the recessed structure in the recognition structure that coincides with the convex structure at the tank bottom after the tank is installed in the induction equipment for product thermal treatment.
EFFECT: invention provides the same or similar heating results for different types of tank material by selecting a voltage variation curve suitable for the tank material type.
