| Abstract: | The updated mathematic models for calculation of the central pipe formotion in continuous cast billet are built up, based on the material balance and the previous published models. From derivation of models the methods for determining both the position of water cooling zone and ratio of the cooling fates of the surface against the center, G are also given out. |
