METHOD FOR DESCALING HOT ROLLED STRIP Russian patent published in 2003 - IPC

Abstract RU 2211737 C2

FIELD: plastic metal working, possibly descaling surface of hot rolled strip at rolling it. SUBSTANCE: method comprises steps of supplying stream of cooling agent from nozzles in cross direction towards moving strip; localizing stream according to strip width and removing cooling agent. Novelty is additional removal of cooling agent outside localized zone at inlet and outlet of said zone. Stream of cooling agent is localized by flows diverging one relative to another by angle whose apex is turned opposite relative to rolling direction. EFFECT: enhanced efficiency of descaling at lowered interim cooling of strip before scale removing and before rolling. 3 dwg, 1 ex
