The present invention provides a roller mill control method capable of automatically controlling a roller mill which is comparatively difficult to operate for operation in an optimum operating condition, and a roller mill controller for carrying out the roller mill control method. The roller mill controller stores beforehand a roller mill characteristic model representing the relation between changes in the values of the operating condition variables detected by a detecting unit (2) and operating parameters, restrictions on the values of the operating condition variables and the operating parameters, an index of performance for evaluating the values of the operating condition variables and the operating parameters. A Simplex algorithm calculation system (5) included in an optimizing control arithmetic unit (3) calculates changes in the operating parameters by a Simplex algorithm by using the roller mill characteristic model, the restrictions and the index of performance to select the values of the operating condition variables detected by the detecting unit (2) so that the index of performance is optimized under conditions meeting the restrictions, and then, a main control unit (4) controls the roller mill on the basis of new operating parameters.

Method for controlling a roller mill

A target shape adjusting equipment of a metal material furnished with an expert system by adaptive inference and learning inference processing for applying the engineering know-hows of skilled operators being engaged in the control of the shape in the width direction of a band-like or plate-like metal material which is running after a specified treatment has been given thereto, to adjust the shape thereof by giving the target shape data to a shape controlling section for contorlling the shape.

Equipment for adjusting the shape of a running band-like or plate-like

A method of and a device for controlling a counter of a rolled material on a multi-high rolling mill with which method and device very accurate shape control can be attained with certainty and in high responsibility. A strip shape of a rolled material in its widthwise direction on the outgoing side of the rolling mill is detected by a strip shape meter, and the detected shape and a strip thickness are synthetically evaluated using a total performance index. Operation amounts for a strip shape controlling actuator and a strip thickness controlling actuator which make the value of the total performance index minimum are always found out, and the actuators are controlled simultaneously in accordance with the operation amounts to control the strip shape of the rolled material. The apparatus comprises a saddle receiver the vertical position of which is controlled by a roll gap controlling device in accordance with an estimated value to change the gap between upper and lower work rolls of the rolling mill.
