The wedge and board width center section board thickness and influence coefficient

摘要

Setting control method of the wedge in plate rolling which can roll the board of identical board thickness on job side and driving side is offered.Roughly it has the wedge total 4 which measures the board thickness of board cross direction on coming out side of mil 3 in those which are rolled reversibly the plate hot rolling roughly with the mil, roughly it calculates the wedge which was measured with a wedge meter with influence coefficient of the wedge, for the roll gap leveling of the mil calculates the roll gap leveling controlled variable, in roll gap leveling of the mil impresses this roll gap leveling controlled variable roughly with closed-loop control.
