    摘要: Continuous production of metal fiber is provided by delivering molten metal at low pressure to a multi-edged, rotating casting drum. The metal is delivered through a wide orifice in a tundish frontwall in close proximity to the casting edges. The flow to the orifice is controlled by means of a constrictive channel upstream of the orifice communicating with the source of molten metal.

    摘要: An apparatus for continuously casting metallic strip material includes a tundish, and a nozzle comprising a curvilinear element, with an orifice passage in the element having substantially uniform cross-sectional dimensions throughout the longitudinal extent thereof. Disposed outside the nozzle is a cooled casting surface movable past the nozzle in a direction substantially perpendicular to the longitudinal axis of the orifice passage. First and second inside surfaces of the element define the orifice passage through which molten metal is fed to the casting surface.

    摘要: A recirculating fiber filter (1) and method is provided for removing particulates from moving fluid streams. High aspect ratio fibers (2) are used which readily nest with each other to form the high voidage fiber filter bed. In the method, fibers are continuously removed from the bottom of the bed regenerated to remove particulates and recycled back to the top of the bed and distributed thereon. Dirty fluid is passed from the top to the bottom of the filter. Dendrites of the particulate impurity appear to buildup in a thin section (A) at the top of the filter and provide the primary mechanism for further particulate entrapment. Recirculation of fibers offers a continuously fresh volume of fibers at the top for capture of particulates.

    摘要: A process for casting metallic strips thicker than from melt-drag processes but thinner than the inherent normal thickness of a cast melt is disclosed. The disclosed process casts molten metal, without decanting or accelerating the molten stream, onto a channel-shaped chill surface. After casting, the molten strip acquires a high thermal gradient. Following thermal shrinkage of the underside the molten top layer is squeegeed using a chill roll to uniformly distribute and crystallize the top surface.

    摘要: A method for continuously casting strip material onto a casting surface moving past a nozzle in a molten metal holding tundish is disclosed comprising the steps of pouring molten metal into the tundish at a rate sufficient to establish a metallostatic head pressure of at least one-quarter pound per square inch at the nozzle within one second after pouring is initiated, and pouring additional molten metal into the tundish at a rate sufficient to maintain a substantially constant operating pressure at the nozzle throughout the casting operation. A tundish for holding molten metal to be cast into strip material onto a casting surface moving past a nozzle in the tundish, is also disclosed comprising a front wall having an inside surface, a rear wall having an inside surface and sidewalls enclosing a molten metal holding area defined between the inside surfaces of the front and rear walls. The inside surface of the front wall converges with the inside surface of the rear wall at least at a location near the nozzle.
