<p><P>PROBLEM TO BE SOLVED: To provide a load distribution control device for a continuous rolling mill capable of using a state after the manual intervention by an operator of the mill as a target value of the rolling load ratio. <P>SOLUTION: The load distribution control device includes rolling load detectors 5-7 provided on each stand of a continuous rolling mill, a load distribution controller 11 for calculating the thickness correction amount to each stand based on the experienced rolling load, rolling-reduction position controllers 8-10 for controlling the rolling-reduction position of each stand based on the thickness correction amount, and a rolling-reduction manual intervention functional unit 16 for manually correcting the rolling-reduction position of each stand irrespective of the result of computation of the load distribution controller 11. The load distribution controller 11 resets the target value of the rolling load ratio based on the experienced rolling load at that time when the rolling-reduction position of each stand is manually corrected by the rolling-reduction position manual intervention functional unit 16. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
