  • Method and apparatus for casting amorphous filament using a crucible with a boric oxide seal
    Patent number: 4260007
    Abstract: An improvement is provided in a method for the continuous casting of glassy metal alloy filaments wherein molten alloy is extruded from a pressurized crucible through an extrusion orifice onto a rotating quench surface. The invention provides a boric oxide seal for the extrusion orifice that prevents oxidation of the molten alloy prior to initiation of extrusion. At initiation of extrusion, the seal is conveniently expelled from the orifice with the leading surge of the extruded molten alloy.
