Title: Controller for load balance in multistage continuous rolling mill
Inventor: MIURA KEIICHI
IPC: B21B37/20
Filed: 1980-01-31
Abstract: PURPOSE: To prevent the fluctuation of product shape and the load concentration in a specific  stand, by holding constant the rolling load depending on the distribution pattern of initial rolling  load for each stand, and by always controlling the rolling load distribution for each rolling stand  according to the sheet thickness on the run-out side of the final stand.   
     CONSTITUTION: If the material ST approaches the first stand F 1 , the setup computer 32 presets  the roll gap, roll speed, etc., of the rolling stand on each stage. At the same time, the computer 32  transmits the absolute value of sheet thickness on the run-out side of each stand required by the  control activity, together with the various rolling conditions DA, as the data DB, to the load  balance controller 31, and also determines the critical number of stands for holding good the sheet  shape. When the material ST is bitten by the second and following stands, the automatic thickness controller 8 starts the control of sheet thickness. When the material ST arrives at the product  thickness detector 11, the goodness of the shape or flatness is decided, and the roll gap and the  roll bender are corrected. At this moment, the rolling load of each stand is stored as the initial  load distribution pattern by the load balance controller 31, which then starts the control for redistributing the rolling load.
