Abstract
PURPOSE: To prevent the tear, etc., of the weld zone on purpose to contrive the improvement of the production efficiency, in the case that the cold rolling is carried out before the picking process, and then, the continuous cold rolling is carried out obtaining the required thickness, by installing the weld zone detectors on the feeding side and the outgoing side of the rolling mill for the purpose of controlling the draft of the rolling mill according to the signal from these detectors.
CONSTITUTION: The hot rolled raw sheet 12 is supplied from the uncoiler 1 and is connected to the rear end of the forward hot rolled raw sheet 13 being welded by the welder 2; hereby, the forward and following hot rolled raw sheets 12, 13, are formed into one sheet. Then, the hot rolled raw sheet 13 is sent to the rolling mill 4 through the strip storage 3, and is cold rolled at the draft percentage higher than 3% in the rolling mill, 4. Following to this rolling, the strip 14 is pickled in the pickling tray 6, and then, is rolled at the draft percentage of 60W80% into the required size by the continuous cold rolling mill train 7. The weld zone detectors 9, 10, are installed on the feeding side and the outgoing side of the rolling mill 4; if the weld zone is detected by the detector 9, the detecting signal is transmitted to the quick draft controller 11, which opens the specified draft; if the weld zone is detected by the detector 10, the specified closing is given to the draft; hereby the tear at the weld zone is prevented.
