<p>PURPOSE:To optimize the shape of rolled plate by obtaining profile change by heat from rolling histeresis when the change in contact between metal to be rolled and working roll at the time of rolling metal plate is controlled by means of a roll bending device or a roll coolant device. CONSTITUTION:In rolling metal, the setting board 11 is given a rolling condition of the width and thickness of plate, etc. Then, a control target for shape is calculated by the targent board arithmetic unit 12 and also a roll border condition is calculated by the border temperature arithmetic unit 13 from signal from the roll coolant device 5 and rolling condition from the setting board 11. The control target and the rolling condition are sent to the roll thermal profile arithmetic unit 14 to calculate thermal profile. Previous to the operation, actual data on already rolled product is transferred from the roll thermal expansion arithmetic unit 16 to correct the calculated value on the basis of the actual data. The thermal profile value is sent to the plate width equivalent crown arithmetic unit 15, and the result is then sent to the roll bending device 4 and roll coolant device 5.</p> |
