Abstract (en)
[origin: WO8804586A1] In a process for continuously casting high melting point metals with a cast cross-section of nearly final dimensions according to the principle of communicating tubes, the outflowing metal is no longer exposed to reoxidation as it solidifies, the molten metal (also effervescent molten masses) can be degassed immediately before casting, and a temperature and analysis correction can also be carried out immediately before casting. The conditions are met by pressing the molten metal from a higher reservoir through the communicating tube (8) into a pressure vessel (13) with a gas dome (20). The molten metal is then conveyed through a vertical tube (14) immersed in the molten metal through the gas dome into an essentially vertical, oscillating and independent casting die (15). The continuously cast bar is deflected, while it is being formed, in an arc from the vertical into the horizontal and then removed.
