FIELD: metallurgy.
SUBSTANCE: rolling mill of cold-rolling mill for pipe rolling contains movable force stand with bearing rails and rack bars and movable cartridge with working rollers, bearing assemblies, pinion gears and removable gages. Removable gages are implemented as segmented and are fixed on working rollers by bandages. Each bearing roller by width is implemented with additional bearing sections, enveloping bandages of gage. Each bearing rails allows longitudinal grooves doe passing of mentioned bandages, butt grooves for passing of gage and inclined groove at front butt for installation of movable cartridge into load-bearing stand.
EFFECT: invention provides increasing of quality of rolled pipes ensured by increasing of rigidity, to reduce steel intensity, labour-output ratio of its fabrication and power consumption during stand operation.
