Strand-guiding stand for a continuous casting installation

摘要

To adjust the strand-guiding elements (2, 3) situated opposite one another on the strand-guiding stand to different strand thicknesses (47), one part (8) of the strand-guiding stand can be displaced along the tie (7), for which purpose bushes (13) with helical supporting surfaces (14) are rotatably mounted on the ties (7), the displaceable part (8) of the stand being supported on the helical supporting surfaces (14). There is the problem of dimensioning the adjusting mechanism (37) for the rotatable bushes (13) purely in accordance with the forces required to rotate the bushes (13) when the bushes (13) have helical supporting surfaces (14) whose angle of inclination is greater than the associated angle of friction. To fix the bushes (13) on the tie (7), an engageable and disengageable clutch (15) is provided between each bush (13) and the associated tie (7). The strand-guiding stand is suitable for continuous-casting installations that can be adjusted to different strand formats. <IMAGE>
