Abstract (en)

A launder system (16) for supplying molten metal (14) from a crucible (10) to a casting mould or a secondary process comprises a nozzle (22) which has a filter (26) positioned within the nozzle (22) to filter the molten metal as it flows through the nozzle (22). The nozzle (22) and filter (26) assembly is removably locatable on the launder system (16), and is used once and is replaced by a new nozzle and filter assembly. This allows efficient cleaning of the molten metal without an increase of probability of blockage due to the filter. The scrapping rate of the launder system is reduced, and hence the launder may be used many times. <IMAGE>
