FIELD: technological processes. ^ SUBSTANCE: tube-rolling plant contains heating furnace, helical primary mill, helical piercing mill and transmitting devices. Problem is solved by the fact that axis of helical primary mill is installed at an angle to axis of helical piercing mill, at that transmitting devices from heating furnace to primary mill and from primary mill to piercing mill, installed at the right angle to roller table that connects heating furnace with piercing mill, are equipped with rotary tables, turn angle of which is equal to angle of primary mill axis location to axis of piercing mill. ^ EFFECT: expansion of technological resources of tube-rolling plant with provision of high-quality cartridges. ^ 1 dwg |
