FIELD: processes and equipment for vacuum electric arc melting of highly reactive metals, namely large size ingot mold of crystallizer of vacuum electric arc furnace.
SUBSTANCE: ingot mold of crystallizer of vacuum electric arc furnace is monitored due to receiving objective data concerning its admissible wear degree. Ingot mold is monitored due to scanning magnetic field outside outer cylindrical surface of ingot mold at passing short -circuit electric current in system electrode-ingot mold.
EFFECT: explosion-proof process of refining metallic ingot, increased useful life period of ingot mold of crystallizer due to reading objective data related to wear degree of mold.
