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 includes a pair of upper and lower work rollsand, and a pair of upper and lower backup rollsand. The rolling apparatus includes a pair of work roll chocksandconfigured to hold the respective work rolls, housingsconfigured to hold the work roll chocks, and load detection devicestoprovided in the work roll chocks, the load detection devices each detecting a load acting on one of the housings from one of the work roll chocks on an entry side in a rolling direction or on an exit side in the rolling direction. The load detection devices are each disposed so as to face one of the housings using a point of effort of a rolling direction force of one of the work rolls as a reference, such that a rotation moment generated on each of the work roll chocks caused by the rolling direction force is equal to a counter rotation moment generated by counterforce against the rotation moment.
