Housingless rolling mill

摘要

A housingless rolling mill having an upper and 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 and lower bearing blocks vertically toward each other. The screw-down cylinder is tiltable with the use of upper and lower spherical. Legs of the lower bearing block are 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 to enable the work rolls to cross at an angle theta . Thus, a strip material is rolled to a satisfactory shape and thickness with the upper work roll and the lower work roll crossing each other.
