Rolling apparatus for flat-rolled metal materials

Abstract

[Object] To provide a rolling apparatus capable of accurately detecting a rolling direction force applied to a work roll chock. [Solution] A rolling apparatus for flat-rolled metal materials including a pair of upper and lower work rollsandincludes a pair of work roll chocksandconfigured to hold the respective work rollsand, housingsconfigured to hold the work roll chocks, and rolling direction force measurement devices, andconfigured to measure rolling direction forces. The rolling direction force measurement devices include a plurality of load detection devices on an entry side or an exit side of the work roll chocks in a rolling direction, and the plurality of load detection devices are provided to one of the housings, and the plurality of load detection devices are disposed in a manner that, during rolling of the flat-rolled metal materials, at least two of the load detection devices are arranged adjacent to each other in a draft direction facing a side surface of a corresponding one of the work roll chocks. In this case, the at least two load detection devices are disposed in a manner that a line extending in the rolling direction and including a roll axis, which is a point of effort of a rolling direction force, is interposed between the at least two load detection devices in the draft direction.
