PLATE THICKNESS CONTROL DEVICE FOR ROLLING MACHINE AND METHOD THEREFOR, AND ROLLING SYSTEM

Japanese Patent JP2023008632

A

To provide a plate thickness control device for a rolling machine that includes monitor plate thickness control and mass flow plate thickness control, and when controlling an outlet side plate thickness, can control the outlet side plate thickness more appropriately, a method therefor, and a rolling machine.SOLUTION: A plate thickness control device 2 for a rolling machine, which controls a rolling machine 1 so that a thickness of a rolled material WK rolled by the rolling machine 1 becomes a target value after termination of rolling, comprises: a monitor plate thickness control part 21 which controls the rolling machine 1 by a monitor plate thickness control signal for opening/closing a roll gap based on the monitor plate thickness control; a mass flow plate thickness control part 22 which controls the rolling machine 1 by a mass flow plate thickness control signal for opening/closing a roll gap based on the mass flow plate thickness control; and a control performance adjustment part 23 which stops the mass flow plate thickness control by the mass flow plate thickness control part 22 in the case opening/closing directions of the roll gaps are not coincident with each other between the monitor plate thickness control signal and the mass flow plate thickness control signal when performing the monitor plate thickness control by the monitor plate thickness control part 21.SELECTED DRAWING: Figure 1
