METHOD FOR MAKING ROLLING ROLLS Russian patent published in 2005 - IPC

Abstract RU 2246999 C1

FIELD: rolling processes and equipment, namely mills for hot and cold rolling.

SUBSTANCE: method comprises steps of mechanical working of used up roll; heating its barrel; quenching roll and tempering it. During mechanical working shortening length of barrel of worked out roll by 1.1 -1.9 times. Heat treatment modes are normalized. Invention prevents concentration of large number of micro-defects in zone of journal to barrel transition.

EFFECT: enhanced quality and strength of rolls.
