Japanese Patent JPS6132082

B2

An inclined rolling stand for reducing a starting material 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 includes three conical substantially 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 rolls are offset relative to each other around the rolling axis by 120 DEG and are so directed with regard to the rolling axis that their extended axes respectively cross the rolling axis at the same short distances while the narrow ends of the conical working rolls respectively include a smoothing zone representing a surface 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.
