Innovative Features in Design and Operation of Large VIM. Furnaces

The most stringent quality demands on super‐alloys and high‐grade non ferrous metals can in most cases be met only be state of the art vacuum melting and casting processes. Today these processes guarantee ultraprecise adjustment of complex analyses, extremely low inclusion and gas contents, and the highest possible reproducibility. The economical operation of such systems enhanced the further development and introduction of many new materials and superalloys with new high‐temperature characteristics.
