摘要： A method of driving conductive molten metal and a melting furnace, the method including making direct current flow vertically between a first electrode, and applying a magnetic field radially toward the center of a melting chamber from the outside of the melting furnace or toward the outside of the melting furnace from the center of the melting chamber to apply torque. The method further includes rotating the molten metal by the torque to discharge the molten metal to a holding furnace, which is provided on the melting chamber, from an outlet opening of a partition plate provided between the melting chamber and the holding furnace and to suck the molten metal, which is present in the holding furnace, from an inlet opening of the partition plate.

摘要： An exemplary embodiment of the invention provides a method of preparing a reinforced refractory joint between refractory sections of a vessel used for containing or conveying molten metal, e.g. a metal-contacting trough. The method involves introducing a mesh body made of metal wires into a gap between metal-contacting surfaces of adjacent refractory sections of a vessel so that the mesh body is positioned beneath the metal conveying surfaces, and covering the mesh body with a layer of moldable refractory material to seal the gap between the metal-contacting surfaces. Other embodiments relate to a vessel formed by the method and a vessel section with a pre-positioned mesh body suitable for preparing a sealed joint with other such sections.

摘要： A casting apparatus has a long cooling jig inclined with respect to a vertical direction. A melt is supplied to and flowed on a bottom surface of the cooling jig, whereby a solid phase is generated in the melt to obtain a semi-solid slurry, and the semi-solid slurry is transferred into and solidified in a cavity of a mold to obtain a casting. The casting apparatus further has a release agent application unit, and a release agent is applied by the application unit to the bottom surface of the cooling jig in a direction toward a supply of the melt at an angle of less than 90° to the bottom surface before supplying the melt to the cooling jig.

摘要： Metal melted and poured into molds, mounted on a conveyor, at a first station. Metal cools to rolling temperature during conveyance to second station where hydraulic ram ejects ingots from molds. Ingots are immediately fed to rolling mill. Molds have interior refractory linings. Embedded in linings are electrical resistance heating elements that heat exterior side surfaces of ingots, between first and second stations, to prevent those surfaces from reducing below rolling temperatures while interior temperatures of ingots reduce to levels suitable for rolling.

摘要： A lead melting furnace or pot, large enough to provide molten metal for 6-18 grid casting machines, is isolated from the casting machines in a separate, remote, room or chamber. The automatically fed, electrically heated, covered and insulated furnace is positioned at a level above the inlet to the casting machines, so that the molten metal is gravity fed from one or more bottom discharge outlets whereby conventional pumps are eliminated and agitation of the molten metal in the furnace minimized. An impedance heated feed line system connects the furnace and casting machines and elevates the molten metal from the relatively low 700.degree.-800.degree. F. temperatures achieved in the furnace to the required 850.degree.-1100.degree. F. casting temperature. A specially designed exhaust hood covers each group (preferably 3) of casting machines to exhaust contaminated gases and simultaneously provide make-up air to minimize the effect on the casting room atmosphere. A scrap conveyor continuously collects excess lead trimmed from the finished grids and returns the reusable metal immediately to the furnace.
