METHOD FOR FORGING LIQUID METAL AND IMPULSE TREATING OF IT SO CALLED "IMPULSE DIE FORGING" Russian patent published in 2002 - IPC

Abstract RU 2194595 C2

FIELD: foundry. SUBSTANCE: method comprises steps of placing billet to melting chamber for heating billet in order to create melt bath; registering time moment of billet melting by means of pickup; shifting die set placed lower than billet towards moving melt; after contact of die set with billet acting upon melt by gas pressure, by pressing and forging efforts through punch; applying upon melt mechanical and electromagnetic oscillations. EFFECT: possibility for making especially complex-shape articles of any metals and also metal-non-metal type composite articles. 8 dwg
