  • Method of setting/controlling wedge in plate material rolling
    Patent number: 7293440
    Abstract: A wedge setup/control method for plate material rolling ensures that the work side and drive side are equal in the rolled plate thickness. The wedge setup/control method, which is used in reversible rolling of a plate material with a rough mill for hot rolling, includes preparing a wedge meter on the outlet side of the rough mill to measure the plate thickness in the direction of the plate width; performing calculations on a wedge measured by the wedge meter, using the influence coefficient of the wedge for roll gap leveling of the rough mill; determining amount of roll gap leveling control; and exercising feedback control to apply the amount of roll gap leveling control to the roll gap leveling of the rough mill.

  • Plant control system including plant operation simulator
    Patent number: 4935886
    Abstract: A plant control system having a plant operation simulator, including an actual plant operation control system and a controller for controlling a simulation of a plant operation in a state that at least a partial function of the actual plant operation control system is off-line. The plant operation control system includes a controller for controlling the plant operation, a process input-output device, a central processing device, an operation desk and a data transmission device.
