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 rolls 1 and 2, and a pair of upper and lower backup rolls 3 and 4. The rolling apparatus includes a pair of work roll chocks 5 and 6 configured to hold the respective work rolls, housings 10 configured to hold the work roll chocks, and load detection devices 21 to 24 provided 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.
