摘要： Techniques are disclosed for casting high-strength and highly formable metal products from recycled metal scrap without the addition of substantial or any amounts of primary aluminum. Additional alloying elements, such as magnesium, can be added to metal scrap, which can be cast and processed to produce a desirable metal coil at final gauge having desirable metallurgical and mechanical properties, such as high strength and formability. Thus, inexpensive and recycled metal scrap can be efficiently repurposed for new applications, such as automotive applications and beverage can stock.

摘要： A cast metal railroad car wheel includes a hub section, a tread section, and an uninterrupted annular web extending between and supporting the tread section on the hub section. The web includes a disk-shaped surface that is continuously concave and that does not include a reversely curved portion. A V-process casting process casts railroad wheels using a vacuum-process casting mold with opposing halves each partially filled with unbonded sand and sand-retaining-plastic film and a vacuum application port and that, when positioned together with the unbonded sand held to shape by vacuum and the film, define a cavity shaped to form a railroad car wheel. The V-process includes feeding molten metal into the cavity, cooling the molten metal, and releasing a vacuum to cause the sand to fall away from the railroad car wheel.

摘要： A metal component is produced using a casting-and-forming tool by casting a melt of a metal alloy into the casting-and-forming tool, wherein the melt is poured from above into a base part or reservoir of the casting-and-forming tool at a first pressure, applying pressure to the melt between the base part and an upper part while the melt is solidifying to a component, wherein the solidifying melt is pressurized at a second pressure, which is larger than the first pressure, when the melt is at least partly, i.e., mostly solidified to form a component compressing the component by relative movement of the base part to the upper part so as to compress the component with a third pressure, which is higher than the second pressure.

摘要： Process and casting mould for producing a cast wheel. A core, which remains in the cast wheel and has a circumferential rim, is inserted into a casting mould having at least one lower mould part and an upper mould part moved relative to one another to close casting mould. Core is positioned by at least one positioning element in a predetermined position in casting mould, so that an end region of positioning element is fixed with a force fit or frictional fit in circumferential rim of the core. A free end region of positioning element, which protrudes from circumferential rim of the core, is placed on a contact surface, which is preferably arranged substantially horizontally during operation, of lower mould part during positioning of core in casting mould. Core is positioned in the predetermined position under the action of the force of gravity.
