| 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 lube (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. |
