| Synopsis: New, unique measuring and control techniques of plate camber have been developed and utilized in the plate mill of Mizushima Works. Features of the techniques are as follows: (1) Plate camber can be measured regardless of sideslipping or turning of a plate during rolling. (2) Any nonuniform plate camber profile can be accurately expressed in the form of the n-th order polynomial. (3) The measured camber is used to calculate the aimed wedge, to which the actual wedge is fed back by a feed-back control system, thereby reducing the plate camber in the next pass. A new control system, which adopted the above-mentioned techniques, has been successfully used and contributing to an increase in yield and a reduction in poor grading and extra processing of plates in the mill. |
