Abstract
A device is described for straightening a curved steel strand cast continuously by means of a casting wheel machine or a curved mold continuously casting machine. The strand is passed between straightening points with rolls, such as straightening, bending, guide, counter rolls and/or corresponding roll pairs, in accordance with a certain physical law, whereby at least two roll pairs applying bending moments to the strand are provided. The first roll pair is at the same time the roll pair located in the direction of travel of the strand directly downstream of the point of emergence of the strand from the casting machine or is formed by the casting wheel (of the curved mold) itself and a corresponding straightening roll. The second roll pair determines transition of the strand from a finite radius or curvature to a straight line (infinite radius of curvature) at the end of the bending zone. Between these two roll pairs other rolls can be located exclusively along the outside of the strand.
