[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.

A roller cage for a profiling line, comprising: a support frame (F1) that entirely delimits a non-operating area (A1) which is external to the line; at least a motor (11) provided with a spindle (12) protruding externally of the non-operating area (A1); at least a shaped roller (13, mounted directly on the spindle (12) and arranged inside an operating area (B) of the line.

Within a housing, divided backing bearing assembled shafts are each moved on any one of a housing bore upper surface 8a constituting the housing, spray frame upper surfaces 9, and rails 13, 19, and 20 of a changing carriage 12 by a sliding apparatuses, and outside the housing, the divided backing bearing assembled shafts are extracted from within the housing or inserted into the housing by being moved on the rails 13, 19, and 20 of the changing carriage 12 by sliding apparatuses. There are thus provided a rolling mill that makes changing of divided backing bearing assembled shafts in the rolling mill easier than conventional, and a method of changing the divided backing bearing assembled shafts in the rolling mill.

A device for capturing and transmitting data of a bearing of a steel mill or rolling mill includes a sensor with a data processing unit arranged in a bearing housing capturing and storing data of a bearing. A data transmission unit in the bearing housing wirelessly transmits data of the sensor to a remote receiver. An energy receiving unit in the bearing housing receives energy wirelessly and transmits it to the data transmission unit and the data processing unit. An energy source with an energy transmitting unit arranged outside the bearing housing supply the energy unit wirelessly. The energy transmitting unit is covered by the bearing housing and is arranged on or in a structural part which adjoins the bearing housing and is part of the supporting structure of mill and remains on the supporting structure of the mill when the bearing housing is removed for maintenance purposes.
