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.

Method of and apparatus for controlling shape of rolled material on

A method for controlling the shape of a cold-rolled material which is capable of switching the roll coolant from a hot coolant to a cold coolant without changing the cooling capacity. The cold coolant is switched to a hot coolant as soon as the supply of hot coolant reaches a maximum flow rate and the flow rate of the cold coolant is controlled to be a value which gives a cooling capacity equivalent to that of the work roll by the hot coolant.
