Abstract

PURPOSE:To prevent an initial wedge an initial camber remaining until the final stand outlet side by performing a rolling reduction leveling control which reduces the initial wedge in the front stage pass and performing a rolling reduction leveling control for the initial camber in the rear stage pass. CONSTITUTION:In the case of performing the finish rolling of a strip 4 subjected to hot rough rolling with finish tandem type continuous hot rolling mills No. 1 - No. 7, the camber and wedge quantities of the end part of the strip 4 are measured by a camber gage 5 and wedge gage 6 at the inlet side of the rolling mills No. 1 - No. 7 at specific intervals. At the front stage stands of the rolling mills No. 1 - No. 7 a rolling reduction levelling control which reduces the initial wedge by changing the rolling reduction levelling quantity based on the wedge quantity is performed. At the rear stage stands of the rolling mills No. 1 - No. 7, a rolling reduction levelling control which reduces the remaining camber by performing the change of the rolling reduction levelling quantity equivalent to the tracking value of the camber quantity for the part where the wedge control of the strip above is performed is executed.
