FIELD: metallurgy.
SUBSTANCE: blanks are charged into furnace, they are moved inside the furnace, heated and delivered with specified temperature from furnace, herewith blanks heating is implemented from above and from below by emission of several optical-quantum generators of high power density - lasers, located lengthwise direction of movement of blanks, and inside the furnace it is created vacuum.
EFFECT: reduction of investments for equipment for heating of blanks, current costs for operation, productivity boosting of heating furnace and dimensions of heated blanks.
