ABSTRACT:
A method related to a start-up phase for continuous casting of a molten metal. The molten metal flows into a continuous casting mold through at least one lateral opening of a submerged nozzle and through at least one bottom opening of the submerged nozzle. The at least one lateral opening may be directed toward a respective at least one wall of the continuous casting mold and the at least one bottom opening may be directed in a casting direction. During a start-up phase of the continuous casting process, a higher ratio of flow rates of molten metal through the at least one lateral opening to the molten metal flowing through the at least one bottom opening may be maintained than the ratio of the flow rates during a subsequent normal operation phase of the submerged nozzle.
