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： A curvilinear metal transfer device with support and compression assemblies that help maintain a constant force on the transfer device's metal outer casing and refractory as the outer casing and refractory expand and contract due to temperature fluctuations. In one embodiment, the support assemblies are configured to apply force to the refractory to keep the refractory in tension with the outer casing to suspend the refractory relative the outer casing. Also disclosed are clamp plates that help hold the refractory in place, and nested lids that cover the curvilinear metal transfer device.

摘要： The invention concerns a casting apparatus which includes a crucible support and induction heating means (14, 16, 18) arranged to receive and support a crucible (10) containing material which is to be melted and poured from an outlet (38). The outlet is positioned on a vertical axis (40). The support and induction heating means also operates to apply induction heating to the material to melt it in the crucible. There is also a translation mechanism which tilts the crucible while the crucible is still supported and while heat is continuously applied to it. This mechanism operates in such a way that during tilting, the outlet of the crucible is maintained on the vertical axis so that the molten material pours from the outlet on the vertical axis. In the embodiments described, the crucible is simultaneously moved vertically towards the mould into which the melt pours.

摘要： Molten metal is injected uniformly into a horizontal mold from a feed chamber in a horizontal direction at a controlled rate, directly on top of the metal already within the mold. A cooling medium is applied to the bottom surface of the mold, with the type and flow rate of the cooling medium being varied to produce a controlled cooling rate throughout the casting process. The rate of introduction of molten metal and the flow rate of the cooling medium are both controlled to produce a relatively uniform solidification rate within the mold, thereby producing a uniform microstructure throughout the casting, and low stresses throughout the casting.

摘要： A trough is described for carrying molten metal, comprising an outer shell defined by a bottom wall and two side walls, an insulating layer filling the outer shell and a conductive U-shaped refractory trough body for carrying molten metal, the trough body being embedded in the insulating layer. At least one heating element is positioned in the insulating layer, adjacent to but spaced apart from the trough body, to provide an air gap between the heating element and the trough body.
