Abstract: A molten metal filter box. The filter box includes a filter housing provided in a flow path for molten metal. A horizontal partition is disposed within the filter housing and has at least one filter receiving passage. A filter medium in the shape of a substantially flat plate is positioned within the filter receiving passage and below an inflow path of the molten metal. The filter medium includes a hole. A filter handling tool is disposed within the hole. The filter handling tool can optionally include a handle secured to the molten metal filter box to suspend the filter medium. Advantageously, the filter medium can be removed by grasping the filter handling tool and removing the filter medium.

Abstract: A molten metal scrap submergence system comprising a furnace and a vortexing scrap submergence well. The vortexing scrap submergence well includes a diverter suspended above the well and oriented for immersion in a bath of molten metal circulating within the well. The system, or an alternative scrap submergence system, can include a hood element disposed in an overlapping position with regard to a top opening of the scrap submergence well. The hood at least substantially seals the top opening. The hood element includes a scrap piece feed chute and a burner allowing carbon containing vapor evaporated from the surface of the molten scrap pieces to combust and form predominantly water. The system, or an alternative scrap submergence system can include internal side walls of the well with a first diameter portion adjacent and above said ramp and a second, larger diameter portion above said first portion.

Abstract: A circulating apparatus for circulating the body of molten metal within an associated furnace is provided. The circulating apparatus includes a molded body with an inlet and an outlet. The inlet and the outlet are aligned with corresponding openings on the associated furnace. The inlet and the outlet define a flow chamber within the molded body. An inductor is secured to a portion of the molded body. The inductor is configured to pump molten metal from the associated furnace and into the flow chamber. A flow channel is spaced from the inlet and the outlet on the molded body. A dam assembly is positioned adjacent the outlet. The dam assembly is movable between a raised position and a lowered position relative to the outlet. The molten fluid flows back into the associated furnace when the dam assembly is in the raised position and the molten fluid flows to the flow channel when the dam assembly is in the lowered position.

Abstract: Disclosed is a flux injector assembly and method for refining a molten material, wherein at least a portion of the material is aluminum, as it flows through a trough. A dispensing rod having a hollow body and a dispensing rim is configured to allow a flux and/or inert gas to travel through the hollow body and be injected into the molten material through the dispensing rim as the molten material flows through the trough. A baffle plate is configured to be positioned within the molten material in the associated trough to allow the molten material to flow passed the baffle plate. The elongated dispensing rod is positioned at a downstream location relative to the baffle plate. The rate of flow of molten material is increased as it passes the dispensing rim of the elongated dispensing rod to inject and mix the flux within the molten aluminum alloy.
