摘要： 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.

摘要： To provide a technique that reliably and quickly melts conductive metal, there is provided a conductive metal melting method including: rotating a magnetic field device formed of a permanent magnet, which includes a permanent magnet, about a vertical axis near a driving flow channel of a flow channel that includes an inlet through which conductive molten metal flows into the flow channel from the outside and an outlet through which the molten metal is discharged to the outside and includes a vortex chamber provided between the driving flow channel provided on an upstream side and an outflow channel provided on a downstream side, and moving lines of magnetic force of the permanent magnet while the lines of magnetic force of the permanent magnet pass through the molten metal present in the driving flow channel; allowing the molten metal to flow into the vortex chamber by an electromagnetic force generated with the movement to generate the vortex of the molten metal in the vortex chamber into which the raw material is to be put; and discharging the molten metal to the outside from the outlet. The conductive metal melting method further includes driving the molten metal present in the outflow channel toward the outlet by an electromagnetic force generated with the movement of the lines of magnetic force as necessary.

摘要： A dross processing assembly includes a stirring station at which dross in a first dross recovery vessel is stirred and a pressing station at which previously stirred dross in a second dross recovery vessel is pressed simultaneously with the stirring of the dross in the first dross recovery vessel. The stirring station and the pressing station may be commonly housed in an enclosure. A conveyor system may advance dross recovery vessels through the dross processing assembly for continuous dross processing.

摘要： There is provided a melt circulating drive device that is compact and obtains a large drive force. A melt circulating drive device is mounted on a side wall of a main bath and is driven to agitate nonferrous metal melt present in a melt storage room storing nonferrous metal melt of the main bath. The melt circulating drive device includes a melt drive tank, a melt drive unit, and a partition plate. The melt drive tank includes a hermetically-sealed drive chamber, the drive chamber includes an opening allowing the drive chamber to communicate with the melt storage room, and the melt drive tank stores melt, which flows from the opening, in the drive chamber. The melt drive unit is installed above the melt drive tank. The melt drive unit includes a permanent magnet unit that is rotated about a first up and down axis while making magnetic lines of force up and down pass through the melt present in the drive chamber of the melt drive tank, and a drive unit for the permanent magnet unit that rotates the melt, which is present in the drive chamber, about the first up and down axis by rotationally driving the permanent magnet unit. The partition plate is disposed upright in the drive chamber of the melt drive tank along a direction where the drive chamber and the melt storage room communicate with each other. An outer end of the partition plate is positioned in a region of the opening. An inner end thereof is positioned in the drive chamber. A melt rotating gap is formed between the inner end and an inner surface of the drive chamber facing the inner end. The partition plate divides the opening of the drive chamber into a first opening and a second opening positioned on both right and left sides of the partition plate. The partition plate is rotated by the melt drive unit, and discharges melt, which collides with one surface of the partition plate, from the first opening so as to allow external melt to be sucked into the drive chamber, in which the pressure of the melt has been reduced, from the second opening.
