FIELD: process engineering.
SUBSTANCE: proposed mill stand comprises stationary bed, support rails, mobile housing with vertical rolls and pads engaged with its drive, roll rack drives and fixed racks and gears fitted on axles, and pressure roll adjustment mechanisms with screw pairs. Easier access to stand components and its accurate positioning are ensured by furnishing it with the frame locked at said stationary bed by wedge joint. Frame bottom part has grooves for locking it against lengthwise displacement at support bars. Frame mid part has recess for roll and ledge for rack. Frame rear end has extending part for bearing rails. Two detachable guides are arranged on stand opposite sides, between support rails and mobile housing. Top part of every guide has surface with two ledges at its edges for reliable joint with mobile housing while bottom part has two horizontal and one vertical surfaces lined by straps to get in contact with support rails and straps of bars fitted in bed. Horizontal and vertical surfaces of every guide direct mobile housing with rolls in rolling axis.
EFFECT: higher quality of rolled tubes and expanded range of tubes, decreased overall dimensions and better operating performances.
