ROLLING APPARATUS FOR FLAT-ROLLED METAL MATERIALS

摘要

A rolling apparatus for flat-rolled metal materials including a pair of upper and lower work rolls 1 and 2 includes a pair of work roll chocks 5 and 6 configured to hold the respective work rolls 1 and 2, housings 10 configured to hold the work roll chocks, and rolling direction force measurement devices 21, 22, 23, and 24 configured 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.

主权项

1. A rolling apparatus for a flat-rolled metal material, the rolling apparatus including at least a pair of upper and lower work rolls and a pair of upper and lower backup rolls, the rolling apparatus comprising:
a pair of work roll chocks configured to hold the respective work rolls; housings or project blocks configured to hold the work roll chocks; and one or more rolling direction force measurement devices configured to measure rolling direction forces acting on the work roll chocks, wherein at least one of the rolling direction force measurement devices includes 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 or one of the project blocks, and wherein the load detection devices are disposed in a manner that, on all occasions, a line extending in the rolling direction and including a point of effort of a rolling direction force of one of the work rolls is interposed between at least two of the load detection devices in a draft direction, and the at least two of the load detection devices face a side surface of a corresponding one of the work roll chocks.
