    摘要: A liquid metal jet supplying molten metal during a direct chill casting operation can be optimized to erode the slurry region of the molten sump, but not the solidified metal, at a rate equal to the casting speed. A model of the erosion of solidifying grains in the slurry region of the molten sump can be non-dimensionalized to be used to generate casting parameters (e.g., optimally sized nozzle openings and optimal molten metal flow rates) that would provide the optimized liquid metal jet during the casting process. An ingot cast using such an optimized liquid metal jet would have improved macrosegregation properties (e.g., reduced macrosegregation or more evenly distributed macrosegregation), such as having ingot solute concentrations varying from the molten metal supply concentration approximately 10% or less or 5% or less across the width or height of the ingot.

    摘要: A device for producing a cylinder crankcase using a low-pressure casting method or a gravity casting method. The device includes an outer casting mold which includes at least one mold part which, in an assembled state, forms a mold cavity that reproduces, for casting purposes, an outer contour of the cylinder crankcase. A region of the mold cavity forms a cylinder space of the cylinder crankcase. A dosing furnace contains a liquid metal. At least one gate is arranged geodetically below the mold cavity and via which the dosing furnace can be fluidically connected to the mold cavity. Sprue bushings project into the region of the mold cavity that forms the cylinder space of the cylinder crankcase. Each of the at least one gate is connected to one of the sprue bushings.

    摘要: The invention relates to a device and method for producing metal panels. First a metal melt is produced, then a substrate, which has a lower temperature than the metal melt, is brought into contact with it so that some of the metal melt crystallises on the substrate. The substrate is then moved relative to the metal melt so that a metal foil is formed on the substrate. Finally the metal foil is divided into metal panels. According to the invention the substrate comprises grooves which are used to fit partitions between the panels, as well as grooves which are filled with liquid metal. The latter grooves provide a reinforcement for the metal panels. In addition a pattern of recesses and/or elevations can be provided in the substrate so that the same pattern is formed in the metal foil. The pattern may consist, for example, of parallel grooves which ensure that the surface of the foil is enlarged. In the case of solar cells this results in greater efficiency.

    摘要: A retractable metal insert assembly for a core sand mold having at least one sand core element provided with walls to define an opening communicating with a molding cavity, the walls presenting a stepped neck which is dimensionally accurate within .+-.0.002 inches, the mold further including a metal support associated with the core element. The insert assembly comprises: (a) a metal guide detachably secured to the metal support; (b) a metal chill element extendible through the opening to present a metal molding surface which insert has walls mateable with the stepped neck for accurate alignment; and (c) biasing means acting between the guide and insert to urge the mating walls together for self positioning of the insert. The insert assembly can be repeatedly reused in a method of making castings.

    摘要: A method for melting and casting of metals and alloys and an apparatus using the method. The method consists of utilizing a compact assembly for melting and centrifugal casting of metals. The assembly includes a mold or chiller which is rotatable around a vertical axis. The mold communicates with a sealed lower housing containing an oven for the melting of the metal. The assembly is such that the interior chambers of both the oven and the mold are positioned in a vacuum during the entire time of the process of melting of the metal contained in the oven. The oven is movable vertically and is maintained in a position such that the lower extremity of a hollow vertical channel which feeds the mold, remains outside of the molten metal in the interior cavity of the oven when melting is occurring. Thus, the melting is accomplished entirely in a vacuum condition, thereby avoiding the formation of oxides or other chemical compounds.
