摘要： 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.

摘要： A metal scrap submergence device comprising an open top chamber including walls of a heat resistant material, an inlet positioned in a side wall of the chamber, an outlet positioned in the base of said chamber, and a ramp adjacent said side wall of the chamber. The side wall further includes a feature affecting molten metal flow. The feature can include, for example, a baffle, a vane, a passage, a diverging or converging shape and combinations thereof. Similarly, the molten metal flow can be affected by slanting the ramp inwardly or outwardly.

摘要： A flux injector apparatus and method adapted to distribute a predetermined amount of flux to an associated pool of molten aluminum. The flux injector apparatus includes a pressurized tank adapted to store and feed the flux under pressure. A feed mechanism operative to discharge a predetermined amount of flux to an outlet and a controller for monitoring and operating the apparatus. The feed mechanism includes a housing having an inner wall defining a cavity with an inlet and an outlet. A feed wheel is positioned within the cavity and operative to receive a predetermined amount of flux from the inlet, translate the flux within the cavity and discharge the predetermined amount of flux through the outlet of the pressurized tank.

摘要： The present invention is directed to a molten metal pump comprising an elongated pumping chamber tube with a base end and an open top end. A shaft extends into the tube and rotates an impeller therein, the impeller rotates proximate the base end. The tube has a diameter at least 1.1 times the diameter of the impeller. The pumping chamber tube preferably has a length at least three times the height of the impeller. The base end includes an inlet and the top end includes a tangential outlet. Rotation of the impeller draws molten metal into the pumping chamber and creates a rotating equilibrium vortex that rises up the walls of the pumping chamber. The rotating vortex adjacent the top end exists the device via the tangential outlet.

摘要： In accordance with one aspect of the present exemplary embodiment, a molten metal pump comprising a refractory material body defining an elongated chamber is provided. The chamber is configured to receive a shaft and impeller assembly. The chamber includes an open top through which the shaft passes and a bottom inlet. The impeller is located in or adjacent the inlet. The body further defines an elongated passage adjacent to the chamber. An opening provides fluid communication between the elongated passage and the elongated chamber. The elongated passage is in fluid communication with a discharge channel configured to direct molten metal at least substantially perpendicular to an elongated axis of the elongated chamber.
