FIELD: welded tube production, namely mill for welding lengthwise seams of large-diameter finite-length tubes.
SUBSTANCE: mill includes inlet and outer roller tables mounted in foundation; truck having lifting-rotating rollers and transporting rollers; welding apparatus arranged in balcony; apparatus for removing flux skin and belt conveyer with box for flux. Truck is mounted with possibility of motion on rail path. Lifting-rotating and transporting rollers are mounted in respective casings. Apparatus for removing flux skin is in the form of two chutes arranged mutually in parallel along axis of truck motion and having openings; double-horn rotary lever. Chutes are mounted on truck with possibility of horizontal motion with the aid of parallelogram mechanisms joined by kinematics links through tie rods and axles with casings of lifting-rotating rollers. Carrying roller and elastic scrapers are mounted in double-horn lever. Belt conveyer with box for flux is arranged under level of rail path.
EFFECT: lowered size, decreased metal consumption of mill, enhanced operational reliability of mill equipment.
