METHOD OF THERMAL NONCORROSIVE PROCESSING OF PRODUCTS FROM STEELS AND ALLOYS AND BLAST FURNACE OF RESISTANCE FOR ITS IMPLEMENTATION Russian patent published in 2009 - IPC C21D1/76 F27B1/09 F27B5/04 

FIELD: metallurgy.

SUBSTANCE: products, subject to thermal treatment, are laid into adjustment, it is connected to cover of container by means of capture. Adjustment is loaded into container, it is provided pressure-tight joint of cover with container by means of rubber gasket, it is blown by inert gas. It is places container in heated retort of furnace, water is fed for cooling of cover. Feeding of water and inert gas is stopped at temperature of products not higher than 200°C, then cover is disconnected from container and adjustments and cooled products on air. Blast furnace contains casing with located in it pot heater, on shelves of which it is installed nichrome heater, retort made of oxidation-resisting steel, by generatrix of which it is implemented airtight channel with installed in it thermopairs; connected to thermoregulators, container, closed by water-cooled cover, reflecting elements, connected to cover. On cover it is fixed by means of captures adjustment with products. Through the cover there are passed pipe for input of operating environment into container, pipe for output of operating environment from container and branch for creation of vacuum in container.

EFFECT: improving of products' treatment and furnace productivity.
