Filed: 1937-12-07
Abstract: 501,308. Refining metals ; rotary furnaces. THIEMANN, W H. A. (Durener Metallwerke Akt.-Ges.) Dec. 7, 1937, No. 3390]. [Class 82 (i)] [Also in Group XII] Light-metal scrap is refined by repeated pouring of the molten metal and a saline melt from one receptacle to another in such a way that the saline melt (which rises to the top) is first poured, after which the metal is poured in a thin flat stream into it. The pouring may take place between two crucibles or furnaces, or over a partition in a tilting or rotary furnace, and the flat stream of metal may be subdivided. Fig. 4 shows a section of a rotary furnace in which partitions 1, 2, 3 divide the interior into compartments each large enough to contain the whole of the metal and saline melt. As the furnace revolves the saline portion of thu melt first flows over a partition into the lowermost chamber, after which the metal flows over in a thin flat stream into it. The partitions are preferably undercut, as shown in Fig. 5, to ensure clean pouring, and may be provided with radially and inwardly directed projections to subdivide the stream. Pre-alloys may be added to the molten metal, the process of pouring ensuring thorough intermixing.
