Abstract
PURPOSE:To shape controller made possible to effectively, exactly and automatically control the shape, by inputting all data required for the shape control before starting the rolling work, by operating the set point for the rolls' crossing angle, etc., and the initial value of the sheet shape both the most suitable for the rolling work just to be started, and by producing the output for controlling the shape. CONSTITUTION:The initial set point arithmetic unit 33, included in the shape controller 32 enclosed by the single-dotted chain line, operates the most suitable roll angle theta and the displacement X of the rolls' cross point from the mill center, according to the rolling data like as the rolling load P, the sheet breadth W, the sheet thickness H, the quality of material, etc.; from these values, theta and X, the initial set point of the roll chock displacement is operated, and besides, the initial set points of the most suitable roll bending loads respectively on the operating side and the driving side are operated. These operated values are added to the signals sent from the roll chock displacement detectors 41-44, the roll bending load detectors 54, 54, etc., by the adders 45-48 whose signals are sent to the roll chock initial 34, etc. Meanwhile, during the rolling work, the detecting signal of the shape detector 52 is added 40 to above stated initial set point, and the shape is controlled to the correct shape.
