Asymmetric deformation of metal and front flexure of thick sheet in rolling. Part 2

Laboratory experiments are followed by the rolling of sheet in industrial conditions on 3600, 2300, and 5000 thick-sheet mills. The parameters that affect the front curvature of the sheet leaving the rollers are identified. The sheet-reduction conditions on the 3600 and 2300 mills are assessed, so as to determine the rolling parameters responsible for asymmetry of the process in the vertical plane. Means of compensating the sheet flexure at the roller exit are proposed.
