Slant rolling mill for reducing full or hollow cross-sections, in the case of which a driven roller support (rotor; 8, 28) can be rotated on a hollow shaft permitting passage of the material (3) to be rolled and has three working rollers (17) which are inclined with respect to the axis of the material to be rolled, are offset with respect to one another by an angle of 120 DEG , are conical, can be adjusted with respect to the axis of the material to be rolled, and each one of which being connected, by means of gears, via pairs of bevel wheels, an intermediate wheel and a planet wheel, to the hollow shaft which supports a sun wheel and is driven at a controllable speed of rotation, each working roller (17) being mounted in a casing together with a roller shaft, the bevel wheel mounted on the roller shaft, the intermediate shaft with a second bevel wheel mounted on it and an intermediate wheel, and being combined in each case to form a rolling head (16, 30), and the roller heads (16, 30) being pivotably seated in the roller support (rotor; 8, 28) about the axes, which are parallel to the axis of the material to be rolled, of the intermediate shafts to permit adjustment of the angle of intersection of the roller axis and the axis of the material to be rolled. To produce and/or maintain a specific relationship between the rotary positions of the three rolling heads (16, 30) with respect to one another, the latter are surrounded by an adjusting ring (31) which is centrally arranged with respect to the axis of the material to be rolled, to form a common centre of the rolling head casings (16, 30), and can be connected to the said adjusting ring (31) by means of gears (43 to 51). <IMAGE>
