Launder system for supplying molten metal and a launder nozzle

摘要

A launder system for supplying molten metal from a crucible to a casting mould or a secondary process has a nozzle with a filter positioned therein to filter the molten metal as it flows through the nozzle. The nozzle and filter assembly is removably attachable to the launder system, and is used once and then replaced by a new nozzle and filter assembly. Efficient cleaning of the molten metal thus occurs without an increase in blockage due to the filter. Additionally, the scrapping rate of the launder system is reduced, allowing multiple usage of the launder.
