摘要： The filtering molten metal injector system includes a holder furnace, a casting mold supported above the holder furnace, and at least one molten metal injector supported from a bottom side of the casting mold. The holder furnace contains a supply of molten metal. The mold defines a mold cavity for receiving the molten metal from the holder furnace. The molten metal injector projects into the holder furnace. The molten metal injector includes a cylinder defining a piston cavity housing a reciprocating piston for pumping the molten metal upward from the holder furnace to the mold cavity. The cylinder and piston are at least partially submerged in the molten metal when the holder furnace contains the molten metal. The cylinder or the piston includes a molten metal intake for receiving the molten metal into the piston cavity when the holder furnace contains molten metal. A conduit connects the piston cavity to the mold cavity. A molten metal filter is located in the conduit for filtering the molten metal passing through the conduit during the reciprocating movement of the piston. The molten metal intake may be a valve connected to the cylinder, a gap formed between the piston and an open end of the cylinder, an aperture defined in the sidewall of the cylinder, or a ball check valve incorporated into the piston. A second molten metal filter preferably covers the molten metal intake to the injector.

摘要： An injection apparatus for introducing fluid material, such as a reactive element to a molten metal bath while resisting undesired oxidation. The injection apparatus consists of a body assembly having a chamber defined therein, and inlet and outlet passageways communicating with the chamber which cooperate to define a passageway therethrough. The lower end of the outlet extends below the surface of the molten metal bath. Purging gas is introduced through a gas inlet and provide a substantially purged atmosphere throughout the molten metal passageway. The atmosphere in the passageway is purged in order that the fluid material can be safely introduced into the molten bath. The injection apparatus is readily assembled and disassembled by means of a unique clamping device employed with the body assembly.
