Abstract: Rolling mill computer control system includes an operator update program which accepts requests from a mill operator to modify computer setups for speed and screwdown presets. When under computer control and abnormal mill conditions arise, the computer programs will accept operator updates from the same presetting devices which are used in manual operation. The operator update program calculates speed and draft coefficients which are used to update the basic computer schedule calculations so as to accommodate the abnormal mill conditions. Additional presetting devices, such as load distribution switches, are eliminated so as to minimize operator confusion and simplify operator panel layout.
