  • Patent number: 4544014
    Abstract: A machine for casting battery grids in a continuous manner includes a rotary cylindrical drum in the outer peripheral surface of which the battery grid pattern is machined as a cavity. A shoe is arranged against an arcuate segment of the peripheral surface of the drum. An orifice slot in the shoe has an opening at the peripheral surface of the drum. Molten lead under superatmospheric pressure is directed into the orifice slot in an amount in excess of that required to fill the grid cavity on the drum through the opening in the orifice slot as the drum rotates. Means are provided in the shoe for maintaining the molten lead in the orifice slot in a highly fluid condition and for causing the lead filling the grid cavity to solidify rapidly as it advanced beyond the opening of the orifice slot.

  • Patent number: 4537240
    Abstract: Moving molds are disposed in one array around the periphery of a casting wheel. A series of consecutive moving molds are closed during a predetermined angle range of the periphery of the casting wheel to define a continuous mold cavity between the closed moving molds and the casting wheel. A molten metal is poured into the thus defined continuous molding cavity at an upstream end thereof and is solidified while the casting wheel is rotated in unison with the moving molds. Then, moving molds are opened just before they arrive a cast outlet, and the cast is taken out.

  • Patent number: 4527613
    Abstract: A method and apparatus for forming a cast metal ribbon with a slit along the ribbon length includes the step of or a means for generating a controlled disturbance of the cast ribbon along a defined and localized width. The disturbance may be generated by a highly defined, needle-sized stream of gaseous media into the ribbon prior to complete solidification, or alternatively, a needle-like ceramic stylus. The dynamic pressure of the gaseous media or depth of stylus may be adjusted to completely penetrate the ribbon, severing the ribbon into multiple ribbons in a single casting; or alternatively, to only partially penetrate the ribbon, forming a score line of weakening and producing multiple ribbons readily detachable from each other along adjoining edges.

  • Patent number: 4527614
    Abstract: An amorphous Co-based metal filament having a circular cross-section made of an alloy composed mainly of Co-Si-B or Co-Me-Si-B (wherein Me is at least one metal selected from the group consisting of Fe, Ni, Cr, Ta, Nb, V, Mo, Mn, W and Zr). This filament is produced by jetting the above alloy into a rotating member containing therein a cooling liquid through a spinning nozzle having a hole diameter which is determined according to the amorphous metal-forming ability (critical thickness to form an amorphous phase) to thereby cool-solidify the jetted molten alloy and form a filament, and then winding the filament continuously on the inner walls of the rotating member by the rotary centrifugal force thereof. This amorphous metal filament is corrosion resistant, is tough and has high electromagnetic characteristics, and is very useful as industrial materials, such as electric and electronic parts, composite materials and fibrous materials.

  • Patent number: 4512384
    Abstract: The present invention is an improvement over, and an adaptation to continuous casting, of known processes in which a molten metal such as steel is atomized under non-oxydizing conditions and projected at high velocity against a suitable target. The distance to the target is such that the atomized particles solidify on their way and hit the target in a solid, yet still plastic, state to be welded onto said target by their kinetic energy. Applicant has found a way to adapt such process to continuous operation, and more particularly, to production of wide slabs of great length and relatively small thickness, say, typical 1.5".times.60" section and achieving that at great speeds of operation, such as 100 to 500 tons per hour which speed makes it possible to place it upstream of a continuous hot strip mill and thus produce, say, 0.060".times.60" strips in one continuous operation, from molten metal. (Such mills cannot maintain their thermal balance if the speed of the workpiece is too slow).

  • Patent number: 4489772
    Abstract: A continuous casting machine for battery grids includes a rotary drum on the outer peripheral surface of which the battery grid pattern is formed by a series of grooves. The peripheral surface of the drum mates with a shoe through which molten lead is directed into the grooves as the drum rotates. The outer periphery of the drum is a shell that is connected to rotary side plates by means of roll pins that enable the shell as a whole to expand and contract independently of the side plates. The drum is maintained at a desired temperature to solidify the molten lead directed into the grooves of the battery grid pattern by circulating a heated liquid through the drum.

    Abstract: A casting wheel cooling apparatus and method for rapid quenching of molten metal is provided. The cooling apparatus provides a multiplicity of axial conduits around the periphery of the wheel, close to the chill surface. In operation, molten metal deposits on the chill surface of the rapidly rotating casting wheel. The molten metal cools and solidifies, transferring heat to the casting wheel. By flowing coolant, preferably water, through the conduits at a sufficient rate, the heat transfer is generally radial. The molten metal cools uniformly across its width and the resulting metallic strip has substantially uniform properties.
