Abstract

PURPOSE: To realize finishing temp. in a target temp. and to fasten a roiling speed within the limit of cooling capacity by calculating the initial rolling speed and acceleration base on temperature signal of a temperature distribution in the longitudinal direction of a stock to be rolled.
CONSTITUTION: The stock 2 to be rolled 2 is transferred to the finish rolling mill 4 on a delay table 5 provided in connecting to the outlet side of a rough rolling a mill 3. The stock 2 to be rolled whose longitudinal temperature distribution is measure extending over the whole length by a thermometer 1 placed on the delay table 5 is fed to a finish rolling mill 4 provided in connecting with the delay table 5 to be subjected to finish rolling. At the same time, it is cooled by cooling water injected through a descaler 10 and inter-stand spray 11 controlled by a cooling water control device 20 provided attaching to the finish rolling mill 4. Rolling rolls are cooled by roll cooling water 12. The stock 2 to be rolled, fed out of the finish rolling mill 4 is finally wound into a coil.
