ABSTRACT:
For separating slag from heavy metal melts, as iron, steel and copper, a pipe-like body is used into which the slag and metal are drawn and which is rotated about its axis to cause the molten metal to form a layer within the pipe-like body on the outside of a slag layer, the dividing surface between the slag and the metal having the shape of a part of a paraboloid of revolution. The arrangement is tilted at an angle, and at its upper end is provided with a wall over which the slag can escape while holding the molten metal. At its lower end it is provided with a trap arrangement which allows molten metal to flow back downwardly into the main body of melt while preventing the return of the slag.
The arrangement can also be used as a mixer.
