    • The invention relates to a method for producing metal shapes with a partially or totally polygonal cross-section by means of continuous casting in a double-flanged wheel and continuous rolling using a series of at least 3 pairs of rollers with a peripheral flange, whereby said rollers are alternately horizontally and vertically disposed in a symmetrical position with respect to said shape. The inventive method is characterised in that the flanges of the first pairs of rollers are identical to those used to produce shapes with a circular cross-section; the last pair of rollers has flanges defining a section that corresponds substantially to that of the desired shape; the section formed by the grooves of the last pair of rollers has curve radiuses of between 1 and 5 mm at the highest points of the polygon; the sides of the polygon that are not parallel to the air gap pertaining to the last pair of rollers have a clearance angle of

    • The invention relates to a process for producing weldless steel pipes by hot-rolling of a round block in a plurality of stages. During said process, said round block consisting of interstitial-free (IF) steel is inserted and heated in a furnace; the heated round block is subjected to cross-rolling to produce a hollow block at a temperature (temperature at which said block is withdrawn from the furnace) in the region of 1060 to 1200 DEG C; the hollow block is subsequently subjected to breaking down at temperatures about Ar3; the drawn hollow block is subsequently used to homogenise the temperature thereof for further rolling and for grain refining by recrystallisation in a reheating furnace, the temperature being set in the region of 780 to 880 DEG C in the hollow block; the homogenised hollow block is subjected to finishing rolling by stretch-reducing rolling or sizing rolling, the deformation level of finishing rolling being selected to be so high that a grain size of ASTM6 to ASTM9 is obtained; and the resultant weldless steel pipes are cooled in air.
