Supporting and guiding arc for a cast strand

In a supporting and guiding arc for a cast strand, such as a strand having a slab cross section, including

• an arc-inner roller way and an arc-outer roller way, each having rollers supporting said strand on opposite sides thereof,
• one-piece arcuate longitudinal carries extending over the total length of said supporting and guiding arc and accommodating said roller ways,
• pairs of transverse carriers arranged opposite from one another and engaging said longitudinal-carriers from a side of said longitudinal carriers opposite said roller ways, and pairs of transverse carriers being arranged at distances from one another along said longitudinal carriers, and
• drawing anchors connecting said opposite pairs of transverse carriers,
• the improvement wherein each of said arc-inner roller way and said arc-outer roller way comprises:
• only two one-piece arcuate longitudinal carriers arranged laterally of the ends of said rollers at a distance larger than the longitudinal extension of said rollers,
• a plurality of supporting segments, each of said supporting segments having a plurality of said strand supporting rollers mounted thereon, and
• means for separately detachably fastening each of said supporting segments to the two longitudinal carriers of its respective roller way in a strand supporting position, any individual one of said segments upon detachment from its respective pair of longitudinal carriers being removable from said supporting and guiding arc by withdrawal away from its strand supporting position between said longitudinal carriers.
