METHOD OF CONTROLLING HYDROGEN HUMIDITY IN METALLURGICAL POWDER PRODUCTION Russian patent published in 1994 - IPC

FIELD: powder metallurgy. SUBSTANCE: method comprises steps of accumulating hydrogen out of supply system, purifying it and compressing in a metal hydride accumulator; providing predetermined parameters of hydrogen at input of a furnace by mixing afterpurified hydrogen and regenerated hydrogen; controlling hydrogen parameters at output of the metal hydride accumulator by changing temperature of the metal hydride through a feed back line with use of a humidity meter, arranged behind a zone of mixing of hydrogen, had been made up, and regenerated hydrogen. EFFECT: enhanced accuracy of controlling. 1 cl, 1 dwg, 1 tbl
