Abstract

PURPOSE: To control a catenary amt. with good accuracy by detecting the catenary amt. of a thin steel sheet with a catenary sensor disposed between supporting rolls, comparing the same with the target catenary amt. and changing the rotating speed of the supporting roll.
CONSTITUTION: A driving motor 5 of a bridle roll 4 of a catenary type heat treatment furnace is controlled by a speed deviation calculator 8, a PID calculator 9 and a signal selector 25, etc., from the deviation between the set value of a speed setter 7 and the value detected with a speed detector 6, by which the conveying speed of a strip W is controlled. The catenary amt. of the strip W is detected by the catenary sensor 20 disposed between the supporting roll 13 and the adjacent supporting roll (not shown) and the deviation from the set value is determined by a catenary setter 23. On the other hand, the speed change rate is determined by the PID calculator 17 from the deviation between the set value of the above-mentioned speed setter 7 and the value detected with the speed detector 15. The change rate thereof is corrected by the above-mentioned deviation value in a corrector 18 by which the driving motor 14 of the supporting roll 13 is controlled and the catenary is controlled to the target value.
