BILLET PRESSING METHOD Russian patent published in 1995 - IPC

Abstract RU 2049569 C1

FIELD: pressing of billets. SUBSTANCE: method involves extruding billets through die openings and twisting pressed product relative to billet; shifting pressed product axis along arc of a circle relative to billet axis. To obtain billets with constant cross sizes, angular and linear metal flow speed ratio is maintained at constant level. To obtain billets with variable cross sizes, angular and linear metal flow ratio is changed in the process of pressing. EFFECT: increased efficiency and improved quality of pressed billets. 2 cl, 8 dwg
