ABSTRACT:
An apparatus for treating molten material wherein a gas is present during such treatment either by being removed from the molten material or by being added thereto. The apparatus comprises a housing having a continuous spindle or a pair of spindles disposed therein. The continuous spindle is externally threaded at least in its end regions, and the pair of spindles is externally threaded. A plurality of planet spindles are dispoed circumferentially around the spindle are spindles. The planet spindles are also threaded and intermesh with one another as well as with the spindle or spindles. Furthermore, the internal wall of the housing is threaded and intermeshes with the threaded planet spindles. A treatment chamber is defined within the housing and the planet spindles define a wall surface of such chamber. The intermeshing components produce thin layers of the molten material which is carried, by the planet spindles, into the treatment chamber. Since the material is in this form, gas can readily be removed therefrom by connecting the chamber to a vacuum source or added thereto by connecting the chamber to a gas source.
