ABSTRACT:
A furnace (1) has a main holding (2) and a charging well (4) into which molten metal from the holding portion is circulated by means of an electromagnetic pump (7). Metal enters the well as a tangential flow and a stationary turbulator (10) is located in the path of the flow so as to upwardly and transversely deflect the flow. Resulting turbulence within the well enhances the rate of assimilation of solids into the melt without resulting in excessive oxidation. The method is suitable for melting aluminium swarf.
