HOUSINGLESS ROLLING MILL

摘要

A housingless rolling mill comprises an upper work roll and a lower work roll, upper bearing blocks and lower bearing blocks for supporting the upper and lower work rolls, and screw-down cylinders for pulling the upper bearing blocks and the lower bearing blocks to each other vertically on an entry side and a delivery side. The screw-down cylinder is tiltable by the use of an upper spherical bush and a lower spherical bush. Legs of the lower bearing block are supported so as to be turnable in a roll cross direction. Lower cross cylinders are provided at the lower bearing block, and upper cross cylinders are provided at the upper bearing block. Thus, a strip material is rolled with the upper work roll and the lower work roll crossing each other.
