METHOD FOR RESTRAINING EDGE DROP OF ROLLING SHEET
PURPOSE:To restrain effectively an edge drop of sheet by specifying the relations between the cooling capacities of rolling-roll surfaces at the outsides of edge parts and edge parts of a rolling sheet and at the position near the central thereof. CONSTITUTION:A cooling device 6 provided with many c...

| description | PURPOSE:To restrain effectively an edge drop of sheet by specifying the relations between the cooling capacities of rolling-roll surfaces at the outsides of edge parts and edge parts of a rolling sheet and at the position near the central thereof. CONSTITUTION:A cooling device 6 provided with many coolant-spraying nozzles 3c used for entirely cooling a roll 1, is installed at the inlet side of the roll 1. And contraction plates 5 for decreasing a cooling capacity at the edge parts of a rolling sheet, are installed between the roll 1 and the device 6. Nozzles 3a, 3a for spraying a low temperature coolant for the purpose of more intensely cooling roll 1 parts located at both outsides of the sides edges of rolling sheet, are provided to the outlet side of rolling sheet 2. And the cooling of the roll surface is controlled so that A1>A3>A2, where; A1: cooling capacity for the roll surfaces existing at the outsides of the side edges of rolling sheet, A2: cooling capacity for the roll surfaces of the side-edge parts of sheet, A3: cooling capacity for the roll surfaces not far from the central part of sheet. |
