METHOD FOR PROVIDING EXPLOSION SAFETY AT OPERATION OF VACUUM ARC FURNACE FOR SMELTING OF REACTION METAL INGOTS Russian patent published in 2010 - IPC C22B9/20 F27D21/00 

Abstract RU 2403298 C2

FIELD: metallurgy.

SUBSTANCE: phlegmatisation of steam-gas mixture is performed in the method at its emergency formation in working area. As phlegmatiser there used is water vapour; at that, pressure excluding the operation of return valve is kept in furnace working area for the period equal to the ingot cooling time.

EFFECT: invention allows neutralising explosive mixture formed as a result of contact of water from crystalliser cooling system with molten reaction metal, avoiding detonation of explosive mixture.
