METHOD FOR PREPARING ROLLS OF QUARTO SHEET ROLLING STAND FOR OPERATION Russian patent published in 1999 - IPC

Abstract RU 2131311 C1

FIELD: metallurgy, namely rolled sheet production. SUBSTANCE: in order to impart necessary wear resistance to rolls of sheet rolling quarto stand, before operation rolls are subjected to idle rolling in stand at mutual compression under load exceeding rolling effort at feeding cooling and lubricating liquid onto rolls. Cooling and lubricating liquid is directed by pressurized streams to zone of contact in such a way that direction of each stream coincides with direction of peripheral velocity of rolls in respective zone of their contact. Rolls are preliminarily ground for achieving roughness of their surface according to sixth class. EFFECT: significantly increased depth of cold-hardening, enhanced surface rigidity of rolls and their service life period. 2 cl, 1 dwg
