FIELD: rolled stock production, namely screw rolling mills for producing tubes, round bars and short bodies of revolution such as balls at finish operations.
SUBSTANCE: two-high rolling stand includes closed type housing with ports between its crosspieces. In said ports two cartridges with rolling rolls are movably mounted. Traverse bars with mechanisms for rotating them by rolling out angle are secured to cartridges. Rolling rolls moving mechanisms arranged in housing are also mounted in said ports. According to invention mechanisms for rotating cartridges by feed angle are mounted on one crosspiece. Each cartridge has supporting area to which radius segment is rigidly secured. Said segment movably engages with cylindrical turning formed in other crosspiece.
EFFECT: enlarged manufacturing possibilities of stand due to gradual regulation of all technological parameters such as roll grooved pass, rolling out angles, rolling roll feed, improved quality and accuracy of rolled products with wide assortment of their sizes and materials.
