FIELD: metallurgy.
SUBSTANCE: invention refers to tube-rolling mill whereat a row of containers with roller holders is positioned in external structure running along axis (L) of rolling, the containers can slide inside this structure and come out of it. Each container encloses at least three rollers controlled with corresponding drive engines. The rollers can be transferred inside the containers along directions radial to axis of rolling by means of a guide ensuring control of distance from axis.
EFFECT: reduced labour input of rollers control and extraction.
