WIRE DRAWING METHOD Russian patent published in 1997 - IPC

Abstract RU 2086322 C1

FIELD: plastic metal working, namely wire production. SUBSTANCE: method comprises three steps consisting of preliminary cold drawing, hot drawing of blank heated by passing electric current through it and finishing cold drawing. Blank is heated by stages at maintaining normalized values of electric current density and length of heated portions. Preliminary cold drawing is performed at total reduction 45-60%; hot drawing is performed at total reduction 40-80% for cross section of blank subjected to preliminary cold drawing; finishing cold drawing is performed at total reduction up to 60% for cross section of blank subjected to hot drawing. EFFECT: stable quality of ready wire, lowered energy consumption of drawing process.
