METHOD FOR CONTINUOUS EXTRUSION OF ARTICLES OF NON-FERROUS METALS Russian patent published in 1998 - IPC

Abstract RU 2111811 C1

FIELD: manufacture of wire and other elongated continuous sections by extrusion processes. SUBSTANCE: extrusion drum is cooled in two zones: extrusion zone and out-of-extrusion zone with different intensity values. Temperature of metal stuck on walls of groove of said extrusion zone is normalized. Such conditions are realized independently upon length of said extrusion zone. Conditions for intensifying active friction forces are maintained for providing optimal length of extrusion zone at high extrusion rates. EFFECT: enhanced efficiency. 2 cl, 1 dwg
