  • Method for swaying a continuous casting mold
    Patent number: 6363998
    Abstract: A process for producing the oscillation of a continuous casting mold, especially with the use of a hydraulically driven lifting device. So that the heat transfer to the mold and the formation of the casting shell can be effectively controlled, it is proposed that, for any given strand withdrawal rate, the zero line of the mold oscillations relative to the position of the surface of the steel in the mold be moved upward and/or downward during the casting process. As a result of this measure, the quality of the cast product is effectively improved.
