Abstract:
Apparatus for casting a metal product comprising:(a) a casting mold; and(b) a molten metal delivery nozzle for delivering molten metal to the mold, the nozzle comprising:(i) at least one interior surface for containing the molten metal;(ii) at least one substantially planar exterior surface in contact with the casting mold;(iii) a sloped surface extending from the interior surface toward the exterior surface defining a nozzle tip for reducing molten metal turbulence as the metal exits the nozzle;(iv) means for substantially sealing the nozzle against the mold and for thermally insulating the nozzle comprising a layer of resilient, thermally insulating material disposed on the nozzle; and(v) a layer of friction reducing material disposed on the layer of resilient, thermally insulating material.
