In a supporting and guiding arc for cast strands including rollerways supporting the strand on opposite sides, the rollers are mounted on one-piece arcuate longitudinal carriers extending over the total length of the guiding arc. Transverse carriers are arranged in pairs opposite each other along the arcuate longitudinal carriers at a distance from one another, engaging the arcuate longitudinal carriers from behind and being connected by drawing anchors. In order to combine the advantages of guiding arcs assembled of segments arranged in series with the advantages of guiding arcs equipped with continuous arcuate longitudinal carriers, each rollerway has only two arcuate longitudinal carriers. A plurality of supporting segments are inserted between the arcuate longitudinal carriers and are detachably fastened to the same. A plurality of rollers allocated to a rollerway are journaled on each supporting segment. After detachment of a supporting segment from the arcuate longitudinal carriers, the supporting segment is removable from the supporting and guiding arc, together with its rollers.

Supporting and guiding arc for a cast strand

A bow-type continuous casting plant includes a strand bending arrangement arranged below the mould, and a circular-arc guide for the strand following thereupon. The circular-arc guide has oppositely arranged supporting roller ways, and the bending arrangement includes two oppositely arranged bow-structure parts carrying bending and supporting rollers each, and being supported on each other. The distance of the supporting-roller ways of the circular-arc guide is variable in accordance with the strand cross section to be adjusted. One of the bow-structure parts of the bending arrangement is provided with exchangeable roller carriers detachably fastened to it and adapted to different strand cross-sectional formats with their dimensions.
