摘要： A system and method for filling a mold with molten aluminum includes a molten metal pump, a vessel configured to contain molten metal, a mold for receiving molten metal, and a conduit between the vessel and the mold. Molten metal is pumped in the vessel until it reaches a level at which it flows through the conduit and into the mold. The flow of molten metal into the mold is stabilized to maintain a level of molten metal in the mold. A skin of solid metal forms between the mold and the conduit, at which time the pumping of molten metal can cease. The mold with solid metal in it can be moved.

摘要： A scrap melting system and method includes a vessel that is configured to retain molten metal and a raised surface about the level of molten metal in the vessel. Solid metal is placed on the raised surface and molten metal from the vessel is moved upward from the vessel and across the raised surface to melt at least some of the solid metal. The molten metal is preferably raised from the vessel to the raised surface by a molten metal pumping device or system. The molten metal moves from the raised surface and into a vessel or launder.

摘要： The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.

摘要： A degassing and grain refinement system for a cast aluminum-based component and a method of achieving both hydrogen gas presence reduction and grain size reduction in a cast aluminum-based component. Ultrasonic vibrations are imparted to both the liquid metal travel path from its source to the mold to achieve the reduction in hydrogen gas in the molten metal, as well as to one or more locations within the mold to achieve relatively small and equiaxed grains in the component upon solidification.

摘要： In a steel ladle used for handling molten steel, a precast ladle barrel ring forms part of a refractory structure that covers the bottom wall and side wall of the steel ladle. The precast ladle barrel ring is comprised of a monolithic annular ring formed of a high-temperature, cast refractory. The annular ring further includes means for positioning the precast ladle barrel ring in a steel ladle.

摘要： After molten metal has been poured from a ladle 6 into a converter, metal 6b adhering to the ladle 6 is dropped into the ladle 6 on-line, and molten metal is poured from an electric furnace into the ladle 6 into which the metal 6b has been dropped. As a result, the metal 6b is melted and is recovered as a material.
