ABSTRACT An inclined rolling stand for reducing a starting mate- rial to a pipe or rod, which includes a roll carrier adapted to be driven and to permit a central passage of the material to be rolled. The roll carrier comprises three conical sub- stantially identical and axially adjustable working rolls which are adapted to be driven and are inclined relative to the rolling axis at the same acute angle. The three working axis by 120° and from the rolling axis by short equal minimum respectively comprise a smoothing zone representing a sur- face of rotation about the axis of the respective working roll. The respective mantle line of the surface of rotation representing the smoothing zone is so concave that the respective concave mantle line contacting the material to be rolled, when rotating about the material to be rolled, forms the mantle surface of an imaginary cylindrical body.
