| 20080230966 | SCRAP MELTER AND IMPELLER THEREFORE - A device for submerging scrap metal includes: (a) a drive source, (b) a drive shaft having a first end and a second end, the first end being connected to the drive source, and (d) an impeller connected to the second end of the drive shaft, the impeller preferably having two or more outwardly-extending blades. Preferably, each of the blades has a portion that directs molten metal at least partially downward. The impeller design leads to lower operating speeds, lower vibration, longer component life and less maintenance. Additionally, the impeller preferably has a connective portion. The connective portion is used to connect the impeller to the shaft and preferably comprises a nonthreaded, tapered bore extending through the impeller. | 09-25-2008 |
| 20090194919 | DIRECT SMELTING PLANT - A direct smelting plant for producing molten metal from a metalliferous feed material using a molten bath based direct melting process is disclosed.

| 20120146268 | Method and Apparatus for Melting Metal - A stack of copper plates is placed in a melting chamber having a closed roof of refractory material. The stack is placed in a tilted orientation leaning against a side wall of the melting chamber, with lower edges of the copper plates resting on an inclined hearth surface. A door to the melting chamber is closed to block the infiltration of oxygen. A burner is fired into the melting chamber to heat the closed roof of refractory material, and the stack of copper plates is melted under the influence of combustion products from the burner and heat radiated from the closed roof. Molten copper is drained downward from the bottom edge of the inclined hearth surface to avoid immersing the copper plates in a molten bath. | 06-14-2012 |

| 20140117596 | MOLTEN METAL LEAKAGE CONFINEMENT AND THERMAL OPTIMIZATION IN VESSELS USED FOR CONTAINING MOLTEN METALS - A vessel used for containing molten metal, e.g. a trough section for conveying molten metal from one location to another. In some embodiments, the vessel employs refractory liner units of different thermal conductivity to maximize heat penetration into the molten metal from heaters in the gap, but to minimize heat loss at the inlet and outlet of the vessel where the end units contact the housing. | 05-01-2014 |
| 20140265068 | SYSTEM AND METHOD FOR COMPONENT MAINTENANCE - Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain and degas molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel is pulled through the vessel by the pump as it is degassed. This helps maintain a generally constant flow of molten metal through the degassing vessel. Other aspects relate to a system and method for efficiently performing maintenance on components positioned in a vessel. | 09-18-2014 |
| 20150069679 | MOLTEN METAL SCRAP SUBMERGENCE APPARATUS - 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. | 03-12-2015 |
| 20160031007 | MOLTEN METAL TRANSFER SYSTEM AND ROTOR - 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. | 02-04-2016 |
| 20160161186 | MOLTEN METAL LEAKAGE CONFINEMENT AND THERMAL OPTIMIZATION IN VESSELS USED FOR CONTAINING MOLTEN METALS - A vessel used for containing molten metal, e.g. a trough section for conveying molten metal from one location to another. In some embodiments, the vessel employs refractory liner units of different thermal conductivity to maximize heat penetration into the molten metal from heaters in the gap, but to minimize heat loss at the inlet and outlet of the vessel where the end units contact the housing. | 06-09-2016 |

The non-ferrous metal melt pump includes: a container body which includes an inner space and a non-ferrous metal melt passageway, the non-ferrous metal melt passageway having a spiral passageway formed inside a side wall so that a lower end inlet and an upper end open portion, respectively formed in the side wall to be open to the outside, communicate with each other; a magnetic field device, which is rotatable about the vertical axis line, arranged inside the inner space, and the magnetic field device having a magnitude of a magnetic field such that lines of magnetic force moves while penetrating non-ferrous metal melt inside the spiral passageway during the rotation; and a drive device which rotationally drives the magnetic field device. | 10-13-2011 |
| 20120104669 | Non-ferrous Metal Melt Pump and Non-ferrous Metal Melting Furnace Using the Same - A non-ferrous metal melting furnace includes a non-ferrous metal melt pump, a vortex chamber body, and a magnetic field device formed of permanent magnets. The vortex chamber body makes a non-ferrous metal melt flow into a vortex chamber from an inlet, makes the non-ferrous metal melt flow in a spiral shape by applying a driving force to the non-ferrous metal melt in the vortex chamber, and discharges the non-ferrous metal melt from the vortex chamber to an outlet. The magnetic field device formed of permanent magnets is disposed outside the vortex chamber and below a bottom plate of the vortex chamber, and applies the driving force that is generated by current flowing in the non-ferrous metal melt and magnetic lines of force from the magnetic field device formed of permanent magnets. | 05-03-2012 |

| 20090212470 | Melting or Holding Furnace - A melting or holding furnace includes a furnace chamber surrounded by a housing. The chamber holds the melt with a maximum filling level. The furnace also has an outlet opening for transferring the melt to another container. The outlet opening is provided with a shut-off valve for dosing the emerging melt. The valve is covered by melt in normal operation. The housing is connected to a tilting device which tilts the housing in such a manner that the shut-off valve can be freed from melt for the purpose of repairing it even at a maximum filling level. | 08-27-2009 |
| 20120267834 | POURING EQUIPMENT HAVING MELTING FURNACE - To transfer the molten metal that is melted in the melting furnace into the pouring ladle, which is a vessel for transporting the molten metal to the place for pouring, and to further lift the pouring ladle by another crane to pour the molten metal, requires time, such that the molten metal that had a high temperature when melted by the melting furnace is likely to cool down and to cause a defective cast product. To solve the problem the pouring equipment of the present invention pours the molten metal into the mold, comprising the melting furnace that produces molten metal by melting metal material and a driving apparatus that can move the melting furnace backward and forward or in a traverse direction, wherein the pouring equipment moves the melting furnace to the predetermined position by the driving apparatus, and then pours the molten metal into a mold by tilting the melting furnace relative to the mold. | 10-25-2012 |
