摘要： Apparatus and method are provided for damping the induced fluid flow, particularly in the region of the base plate, in an electrically conductive material that is heated and melted in a cold crucible induction furnace. Damping is accomplished by establishing a dc magnetic field such that flow of the electrically conductive liquid metal in that dc magnetic field would induce eddy currents in the liquid metal which would generate forces that tend to oppose the flow. The dc magnetic field may be established by dc current flow in the ac induction coil that induces current in the material, dc current flow in a separate dc coil, or coils, constructed to prevent excessive induced losses, by discrete magnets, or a combination of any of the three prior methods. The dc magnetic field may also be established by dc current flow in one or more dc coils disposed around a magnetic pole piece located below the base of the furnace. One end of the magnetic pole piece is located adjacent to the bottom of the crucible base, so that the pole piece concentrates the dc field into the lower portion of the molten electrically conductive material.

摘要： A method and apparatus for controlling electrode drive speed in a consumable electrode furnace. The electrode drive speed is regulated at a base speed computed from measured changes in physical characteristics of the electrode or ingot, such as changes in weight, as the melt proceeds. The base speed also takes into consideration the known geometry of the electrode, the furnace mold or crucible, the density of the ingot material, and the speed of movement of the bottom of the ingot if any. This base speed is increased or decreased by a trim speed determined from measurement of an electrical phenomenon associated with the consumable electrode process, which electrical phenomenon has a relatively long term value related to the distance between the bottom surface of the electrode and the top surface of the ingot.

摘要： An electroslag remelting furnace with a power connection at the base and a coaxial conductor to eliminate the deleterious effects of magnetic fields upon the pool of molten metal. The furnace may have a vertically moveable crucible, and also a top supported inner mold to form a hollow ingot, for containing the molten portions of the metal as the ingot is formed. The upper portions of the annulus between an inner and outer mold can be greater in width than the width of the lower portion of the annulus to permit increased spacing between the electrodes and the walls of the molds or to permit the use of electrodes of a larger diameter than the width of the lower portion of the annulus.

摘要： An increased diameter wire is formed by drawing a feed wire through a cooled nozzle located in a cooled crucible, and through a liquid metal bath contained within the crucible. Liquid metal freezes onto the feed wire as it passes through the bath, thereby increasing the diameter of the feed wire to form an increased diameter wire product. The invention is particularly suited to forming a wire from a metal composition that would undesirably react with refractory apparatus.
