FIELD: metallurgy. ^ SUBSTANCE: invention concerns rolling. Particularly it concerns operational pipes cold-rolling mill. Operational cold-rolling mill stand contains movable cartridge with body and forming roll, movable force bed with body, wedge-like screw-down gear and bearing rails. Movable force bed of rolling mill is outfitted by spacer block, mounted between its body and bearing rails. Bottom spacer block is fast connected to body housing and implemented with shank end, used as guide for cartridge body, and top spacer block with fixed on it spacer block bearing rails is fixed relative to housing lengthways with ability of in-vertical plane displacement. ^ EFFECT: it is provided increasing of specific speed and productivity of mill by means of reduction of movable mass of operating mill. ^ 2 dwg |
