Abstract: A method for producing strand guiding rollers from prefabricated and semifinished, stored components, which comprise at least roller bearings, prefabricated supporting shafts and semifinished roller shell starting material. The method is intended to produce and deliver a ready-to-assemble strand guiding roller in a short time with minimized stockkeeping costs. Roller bearings are in stock in a type series in accordance with the loads that occur, supporting shafts carrying the roller bearings are in stock in a type series in accordance with the loads that occur, and roller shells are in stock in the form of circumferentially worked bar or tube material in a type series with indeterminate length made to match various roller diameters.

Abstract: To achieve the highest possible separation rate for foreign particles in a tundish combined, at the same time, with a minimized level of inclusions, the refractory-lined interior space of the tundish, as a function of an operating bath level (h), satisfies the condition that a dimensionless ratio (?) of the refractory-lined surface area (Aref) to the filling volume (V) which is delimited by this refractory-lined surface area and the bath-level-dependent exposed surface area (ATop) and results from the relationship ? = A ref ( V ) 2 3 be between 3.83 and 4.39.

Abstract: In a strand guide for a continuous casting plant comprising a plurality of strand supporting elements for supporting the strand, in particular support segments carrying supporting rollers, several support segments being fastened adjacent each other on a supporting framework designed in one piece in its longitudinal extension, each support segment is fastened to the supporting framework by a fixed bearing and a movable bearing spaced apart therefrom in the longitudinal extension of the strand guide, each support segment, by at least one bearing, is pivotally mounted to the supporting framework so as to be pivotable about an axis, the axis being oriented transversely with respect to the longitudinal extension of the strand guide and horizontally, as well as in a vertical plain passing through the longitudinal extension of the supporting framework and by at least one bearing is mounted so as to be adjustable with respect to the supporting framework in a direction toward the pivoting movement of the support segme

Abstract: An adjustment device for adjusting the position of at least one strand supporting element (5) relative to a supporting stand (9, 10) carrying at least one further strand supporting element (6), of a strand guide in a continuous casting plant comprises at least one hydraulic adjustment cylinder (12) contacting a strand supporting element (5) directly or indirectly on the one side and the supporting stand (9, 10) carrying a further strand supporting element (6) on the other side, the movement of the strand supporting element (5) being detectable via a position sensor (17) and controllable by means of an automatic controller (26). In order to safely attain the high precision in positioning the strand supporting elements (5, 6) sought for a strand guide at yet a minimum expenditure and a minimum susceptibility to failure, at least one directional control valve (21A, 21B) capable of being switched via a three-level controller (26) is provided for actuating the hydraulic adjustment cylinder (12) FIG. 2.
