Abstract
A strand guide for a cast strand has a first roller bridge to one wide side of the cast strand and having ends defining two first section corners, a first fixed support adjacent the first roller bridge, a second roller bridge to the opposite wide side of the cast strand and having ends defining two second section corners, and a second fixed support adjacent the second roller bridge. Respective rows of rollers are rotatably mounted on each of the first and second roller bridges for engaging the respective wide sides and thereby supporting and guiding the cast strand. Respective first and second hydraulic positioners connect the first and second corners of the first and second roller bridges to the first and second fixed supports for individual positioning the rollers of the first and second roller bridges symmetrically or asymmetrically relative to the neutral phase of the cast strand.
