METHOD FOR MAKING SEMI-FINISHED PRODUCTS OF HYPER-EUTECTIC SILUMINS Russian patent published in 2005 - IPC

Abstract RU 2262997 C1

FIELD: metallurgy, possibly manufacture of semi-finished products such as rods and tubes of hyper-eutectic Silumins.

SUBSTANCE: method comprises steps of casting ingots; homogenizing it and subjecting to helical rolling for making rod; piercing rod for making tube. Rolling process is realized at axial end push effort while reducing blank between cone cross section rolls. Rolling speed, end push effort, length of sizing zone and inter-roll gap are normalized.

EFFECT: enhanced ductility of metal.
