C. after finishing a heating for soldering. It is better to retain the heat-exchanger during cooling. Alternatively, the heat-exchanger may be cooled to 150.degree. C. or lower and reheated to 400.degree. to 500.degree. C. for at least 10 minutes to up to 30 hours. Furthermore it is preferable to cool at a cooling velocity of not slower than 30.degree. C./min across a temperature range from about 200.degree. C. to about 400.degree. C. after the retainment. Excellent thermal efficiency, high strength and excellent corrosion resistance can be achieved this way.

摘要： A rolling mill comprising an actuator for controlling shapes or conditions of work roll surfaces during rolling and a flatness meter for detecting broadwise flatness of rolled strip to generate an output signal whereby the actuator is operated so as to control the flatness of strip, the output signal being analyzed into a plurality of evaluation indexes. Each of the evaluation indexes is converted by a membership function into a fuzzy quantity having one of a predetermined number of values. These fuzzy quantities are subjected to fuzzy reasoning consisting of a plurality of control rules to set the control value of the actuator.
