摘要： The present invention relates to the providing of a rolling mill that makes it possible to more accurately control the shape of a plate material than has hitherto been possible, and to a rolling method, and is a rolling mill that rolls a plate material using vertical work rolls, and that includes: a coolant jet spray unit that has a plurality of nozzles that are arranged at predetermined intervals in the direction of the rotation axis of the work rolls, and that sprays jets of coolant from the respective nozzles onto the work rolls; a roll temperature estimation unit that estimates a mean temperature of the work rolls; a coolant temperature detection unit that detects a temperature of the coolant; a shape detection unit that detects the shape in the width direction of the rolled plate material; a shape deviation calculation unit that calculates an amount of deviation between a plate material shape detected by the shape detection unit and a target shape; and a shape control unit that controls the shape of the plate material by controlling the spray quantity and/or temperature of the coolant which is sprayed from the coolant jet spray unit based on a difference between the mean temperature of the work rolls and the temperature of the coolant, and on the amount of deviation between the plate material shape and the target shape.

摘要： This invention relates to a rolling mill apparatus and a method of shape control of a rolled strip which enables satisfactory shape control even in extremely thin rolling. A rolling mill apparatus of this invention has a rolling mill, which rolls a rolled strip P between upper and lower work rolls; a shape detecting portion, which detects the degree of flatness of the rolled strip in the width direction of rolled strip which has been rolled by the rolling mill; a spray portion, having a plurality of spray nozzles arranged along the length direction of the upper and lower work rolls, which sprays the upper and lower work rolls with coolant C; and, a shape control portion, which adjusts the spray amount and/or temperature of the coolant C sprayed from the spray portion based on detected information from the shape detecting portion, to control the shape of the rolled strip P. The shape control portion has two control modes, in which the relationship of the detected information of the shape detecting portion and the spray amount and/or temperature of the coolant C sprayed from the spray portion are inversely proportional, and switches between these two control modes based on the strip thickness of the rolled strip P.
