A refractory nozzle assembly comprising a vessel operable to contain a molten metal and having at least one outlet. The assembly includes an inner assembly having an aperture extending therethrough and an outer assembly having an aperture extending therethrough. The inner and outer assemblies are arranged in the outlet of the vessel and are arranged for relative lateral movement such that inner and outer assemblies are operable to move between an open configuration, where the apertures therethrough are generally overlapping, and a closed configuration, where the apertures are not overlapping. The junction between the inner and outer assemblies is located within a periphery of the vessel. |
