摘要： The invention relates to an internally cooled billet guiding roller, preferably for a continuous casting installation, comprising a central rotary shaft (1) and at least one roller tube (4) which is supported on said shaft in a rotationally fixed manner. The aim of the invention is to ensure that the billet guiding roller is better able to bear mechanical and thermal stresses, is suitable for wide billets, and can be maintained in a cost-efficient manner. To this end, coolant channels (22, 22a, 22b, 22c) pass through the roller tube, said coolant channels being arranged in the roller tube, at a constant distance from the outer surface thereof. Preferably, at least one water diffuser ring (5) is arranged between the roller tube and the central shaft.

摘要： The invention relates to an open-ended mould for casting metal strands having a thin slab cross-section, in which the wide lateral walls (1, 2) form a central enlarging region (11) extending from the mould inlet edge (5) to the mould outlet edge (6), and opening up in a rectangular outlet cross-section (22). The aim of the invention is to prevent, to a large extent, strands from detaching themselves from the wide lateral walls. To this end, the contour of the mould cavity (7) in the enlarging area (11) is formed, in cutting planes which are perpendicular to a longitudinal axis (23) of the mould, by curves (15) which form, at least in partial regions, clothoid curves (18, 19, 20, 21) or clothoid-type curves, in which the curvature variations ( DELTA k) are minimised or reduced to zero.
