Abstract
PURPOSE: To obtain the set speed in a short time, by controlling the speed setting with feedback signal, and cntrolling each rolling mill independently by using speed reference circuits after completing the speed setting.
CONSTITUTION: Signals from a sheet passing speed setting device 4 and a maximum speed setting device 5 are supplied to multipliers 111Wn through a changeover circuit 10 to be multiplied by signals from corresponding setting devices 11Wn, and the results thereof are inputted into speed reference circuits 121Wn. The signal from a setting device 13 is fed to the speed reference circuits 121Wn, and the signal from the speed reference circuit 12n is commonly supplied. The signal from the speed reference circuit 121 is inputted into an adder 71 to be added with the signal from setting device 81, and the result thereof is fed to a motor 91. The other rolling mill groups are similarly controlled. In this mechanism, each rolling mill may be controlled independently, so that the operation pitch may be enhanced.
