Rolling method for extra-thin sheet

Abstract

Abstract PURPOSE:To prevent the camber and longitudinal wrinkle of a rolling material by exerting bending tension to the rolling material then coiling the rolling material by a reel having a recessed crown. CONSTITUTION:The rolling material 4 is let off from a supply reel 5, wraps around a large-diameter roll 1, passes the spacing between the roll 1 and a roll 3 then through the roll 3 and a roll 2 and emerges from a CBS rolling mill 10. The material passes a leveler 7 and is finally taken up on the reel 6. The leveler 7 is installed with bending rolls arranged zigzag and the recessed crown reel is used for the reel 6. The material is taken up on the reel 6 after the camber is leveled by the camber leveler 7, by which the camber and longitudinal wrinkle of the extra-thin hard rolling material are prevented.
