STRIP HOT ROLLING METHOD Russian patent published in 1996 - IPC

Abstract RU 2067901 C1

FIELD: elimination of local thickened portion formation on strip lateral edges due to compensation of local wear and to lowered thermal expansion of roll portions in zone of strip lateral edges. SUBSTANCE: method involves deforming strip by rolls simultaneously with feeding the cooling agent along the length of rolls and width of strip; interrupting feeding the cooling agent in the process of deformation to portions of working rolls corresponding to lateral edges of rolled strip at a distance equal to 1/8-1/6 of strip width from each lateral edge strip. EFFECT: higher efficiency. 2 dwg
