High speed finishing block

摘要

A multi-stand block for a rolling mill comprises a plurality of roll stands alternately arranged on opposite sides of a pass line along which a product is rolled in a downstream direction from an entry end to an exit end of the block. Drive shafts are provided on opposite sides of the pass line. The drive shafts comprise coaxial segments interconnected by couplings, with each roll stand being connected to a respective one of the line shaft segments. A block drive is connected to the line shafts at the upstream end of the block, and the couplings are selectively disconnectable to mechanically isolate any downstream line shaft segments and the roll stands connected thereto from the block drive.
