IMPROVEMENTS IN AND RELATING TO MELTING AND/OR STIRRING OF MOLTEN METALS
A method and apparatus for moving molten material within a container are provided. The method comprising: providing apparatus including an electromagnetic mover adjacent a part of the container, wherein the electromagnetic mover has a primary motion axis, the primary motion axis being aligned along the direction of the maximum linear force generated by the electromagnetic stirrer; applying a current to the electromagnetic mover such that changes in magnetic field configuration cause movement of the molten metal within the container; wherein the primary motion axis is inclined relative to the vertical in two different planes; or wherein the longitudinal axis is inclined relative to the vertical in two different planes. The method and apparatus are designed to generate a plurality of different flow zones within the container and/or larger container, the different flow zones differing from one another in terms of their position in the container and/or larger container and/or the different flow zones differing from one another in terms of the relative flow velocities and/or the different flow zones differing from one another in terms of the relative directions of flow.

Oxy-Fuel Combustion System and Method for Melting a Pelleted Charge Material
A system for melting a pelleted charge material including a furnace having a feed end configured to receive a solid pelleted charge material and a discharge end opposite the feed end configured to discharge a molten charge material and a slag, a conveyor configured to feed the pelleted charge material into the feed end of the furnace, at least one oxy-fuel burner positioned to direct heat into a melting zone near the feed end to heat and at least partially melt the pelleted charge material to form the molten charge material and slag, wherein the oxy-fuel burner uses an oxidant having at least 70% molecular oxygen, and at least one flue for exhausting burner combustion products from the furnace.
Apparatus for refining molten aluminum alloys
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.

Liquid lithium supply and regulation
Methods and systems for the production and delivery of lithium metal of high purity are provided herein. In one or more embodiments, method for flowing liquid lithium to a processing chamber is provided and includes flowing liquid lithium from a lithium refill container to a liquid lithium delivery module, where the liquid lithium delivery module is fluidly coupled to the lithium refill container, and flowing the liquid lithium from the liquid lithium delivery module to the processing chamber. The liquid lithium delivery module contains a lithium storage region operable to store liquid lithium and containing a fluid supply line fluidly coupling an outlet port of a liquid lithium storage tank, and a flow meter positioned downstream from the lithium storage region along the fluid supply line and operable to monitor the flow of the liquid lithium through the fluid supply line.
Magnetic pump installation
A magnetic pump in a pump well in a molten metal furnace with a long, relatively thin side wall that wraps around a significant fraction of the circumference of the pump, which facilitates creation of an eddy current based flow field in the molten material with better magnetic coupling, thereby enhancing the effectiveness of the pump. Breach of the well wall will not result in spillage of metal outside the furnace, and the well can be monitored for any such breach or other change so that the pump can be lifted out of the well to protect it from contact with the molten metal in the event of such a breach, or other appropriate action can be taken.
SCRAP SUBMERGENCE DEVICE
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.
