Abstract

The invention relates to a means of purifying molten metal in a vessel, e.g. a tundish wherein an active inclusion-removing covering powder layer may be used in a more cost-effective manner. Accordingly, the invention provides a method of purifying molten metal in a molten metal handling vessel (10, 10'), the vessel having an inlet region (A, A') and an outlet region (C, C') for the molten metal, characterised in that the vessel (10, 10') is divided to include a cleaning region (B, B') between the inlet region (A, A') and the outlet region (C, C') the molten metal (21, 21') is caused to flow from the inlet region (A, A') through the cleaning region (B, B') to the outlet region (C, C') and an active inclusion-removing covering powder layer (23, 23') is places on the surface (22, 22') of the molten metal (21, 21') in the cleaning region (B, B').
