Abstract: In a method for casting prefabricated products in a continuous casting device, having a casting mold and a strand guide downstream of the casting mold, wherein the strand guide has rolls positioned opposite one another in pairs for supporting and guiding the solidifying cast strand, wherein some rolls are drive rolls and others are idle rolls, wherein drives are provided for the drive rolls, and wherein the drive rolls are adjustable against the cast strand in order to transmit guiding forces and strand conveying forces onto the cast strand in interaction with the idle rolls, the drive rolls and the drives are controlled to a preset rotational speed such that the drive rolls have circumferential speeds identical to one another within the limits of a preset casting speed. The motor torques of the drives are maintained at a level as equal as possible below a permissible torque limit value relative to a loadability of the strand shell.

Every other strand passes by the upstream roll pairs and through the nips of the downstream roll pairs and the remaining strands pass through the nips of the upstream roll pairs and by the downstream roll pairs. The horizontal-roll stand is aligned with the vertical-roll stand and has a pair of horizontal rolls forming a plurality of nips aligned in the direction with the vertical-roll stand nips.

Abstract: A coil-laying device has a body having a generally cylindrical outer surface centered on and rotatable about an axis and wall structure forming on the surface a radially outwardly open groove having an intake end, a center, and an output end. The groove has an axial dimension that decreases from the intake end to the center and that increases from the center to the output end. The groove has an angular dimension of about 360° and the center is located about 250° from the output end, so that the center is spaced between 0° and 110° from the intake end. Furthermore the groove is defined between walls that taper together between the intake end and the center at a predetermined angle and that diverge from the center to the output end at a larger angle.

Abstract: A rolling stand has a frame and a pair of support shafts centered on respective parallel shaft axes and each having an outer end projecting past the frame, inner and outer axially spaced bearing portions in the frame, and a gear between the respective inner and outer bearing portions. Each outer bearing portion lies between the respective inner bearing portion and the respective outer end. Respective rolls are carried on the outer ends outside the frame and respective eccentric sleeves rotatable in the frame about the axes engage the shafts at the bearing portions so that a spacing of the axes can be varied by rotating the sleeves in the frame. Respective pressure sleeves surround the shafts between the respective inner and outer bearing portions and are connected to a controller that pressurizes the sleeves and thereby bends the shafts in the frame between the inner and outer bearing portions.
