FIELD: metallurgy.
SUBSTANCE: in the capacity of cooling medium it is used air-water medium, which is created in cavitating facility and as a result structure of cooling medium flow consists of cavitation steam and gas alveoles, dispersed in the water stream, at that air-water medium, allowing reduced density 1-0.01 g/cm3, is created from water and dispersed in it cavitation steam and gas alveoles of diametre 10-6-10-3m and in amount 103-106, passing per second through 10-4 m2 of flow cross-section.
EFFECT: hardening range extension of products made of different materials ensured by management in extended rating with heat abstraction intensity.
