ABSTRACT:
A method of casting and rolling and a roll stand arrangement for rolling finished sections (sheet piling sections) from a preliminary section which arrives from a continuous casting machine and has approximate final dimensions. The method utilizes roll stand arrangements which operate in a rolling line in a reversing operation. A roughing rolling group has in a first rolling line a runout roller table and a transverse transport device following the runout roller table and in a second rolling line a parallel run-in roller table for a compact tandem stand group. A horizontal stand of the roughing rolling group and/or an intermediate edging stand of the compact tandem stand group each have two selectable grooves, wherein a universal stand on the exit side of the compact tandem group has one or more two-high horizontal stands with grooved rolls. When rolling with this stand arrangement, for adjusting the width and for adjusting the shape of a preliminary section having a H-shaped cross-section while simultaneously reducing the cross-section in the roughing rolling group, further reduction of the cross-section with deformation of section ends for forming interlocks is carried in the compact tandem stand group and a final finish-shaping of the interlocks of the section is carried out in the grooves of the two-high horizontal stands.
