An apparatus line for manufacturing seamless steel pipes and tubes includes: a heating apparatus for heating a steel raw material; a piercing apparatus for piercing the heated steel raw material thus forming a hollow material; and a rolling apparatus for applying working to the hollow material to form a seamless steel pipe having a predetermined shape. A cooling apparatus is arranged on an exit side of the rolling apparatus. A heated steel raw material is worked by the rolling apparatus after being pierced by the piercing apparatus, and thereafter, using a surface temperature of a hollow piece before being cooled by the cooling apparatus as a cooling start temperature, the hollow piece is cooled to a cooling stop temperature differing by 50° C. or more from the cooling start temperature and being equal to or above 600° C. at an average cooling speed of 1.0° C./s or more in terms of an outer surface temperature.

The invention relates to a cross-rolling mill, having a plurality of roll shafts (1), each applying a radially directed rolling force to a workpiece, wherein orientation of a roll axis (w) of at least one of the roll shafts (1) adjustably changes about a first adjustment axis (S1) and a second adjustment axis (S2), wherein an intermediate member (9, 10) is arranged between a rotary baring (4, 5) and a control element (11, 12), and wherein the intermediate member (9, 10) includes a rolling force-transmitting rocker pin (14, 15) having a spherical surface (14a, 14b, 15a, 15b) that provides for pivotal movement in a plurality of directions.
