FIELD: process engineering.
SUBSTANCE: invention relates to machine building and metallurgy. It aims at preventing the rejects of continuously annealed metal blank and allowing the maximum metal yield. Continuous thermal processing is continuously controlled by NDT testing of mechanical properties after thermal processing. Electric power intensity is used as a control record. Current power consumption is compared with power inputs derived from preset regression dependence of mechanical properties on power costs per unit for required mechanical properties. Blank heat treatment conditions are adjusted to make the magnitude of power inputs fall in the range of tolerable magnitudes.
EFFECT: sufficient mechanical properties.
