DEVICE FOR THERMAL DEGREASING OF METALLIC CHARGE OF HIGH ALLOYS Russian patent published in 1995 - IPC

FIELD: metallurgy. SUBSTANCE: fuel combustion chamber 1 with branch pipe 7 and nozzle 8 supplying pulverized water onto chips 16, double-walled internal metal jacket 10 in thermal container 3 with flue gas channels 11 as well as plug 12 in the thermal container at the smoke outlet side allow for degreasing in the superheated steam atmosphere which intensifies removal of oil fumes on the one hand and prevents their burning in the thermal container on the other, thus preventing formation of soot compounds which saturate the chips with carbon. EFFECT: intensified thermal degreasing of small chips and prevented carbonization of their surfaces. 4 dwg
