Publication number: 20220297181Abstract: Systems and methods are disclosed for using magnetic fields (e.g., changing magnetic fields) to control metal flow conditions during casting (e.g., casting of an ingot, billet, or slab). The magnetic fields can be introduced using rotating permanent magnets or electromagnets. The magnetic fields can be used to induce movement of the molten metal in a desired direction, such as in a rotating pattern around the surface of the molten sump. The magnetic fields can be used to induce metal flow conditions in the molten sump to increase homogeneity in the molten sump and resultant ingot.Type: ApplicationFiled: June 10, 2022Publication date: September 22, 2022Applicant: Novelis Inc.Inventors: Samuel R.

Patent number: 10975461Abstract: 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.Type: GrantFiled: March 23, 2018Date of Patent: April 13, 2021Assignee: Novelis Inc.Inventors: Sazol Kumar Das, Simon William Barker, Milan Felberbaum, Rajeev G.

Publication number: 20180243822Abstract: Molten metal can be introduced into a liquid sump during direct chill (DC) casting, such as DC casting of aluminum, through a feed tube having a nozzle with an opening. The opening of the nozzle can be shaped and/or sized to generate a jet of molten metal within the liquid sump. The jet of molten metal can exhibit Reynolds number at or above a threshold amount. Such a jet can achieve improved metallurgical properties over standard casting techniques, such as improved grain refinement. A sufficiently high Reynolds number can be achieved by supplying the molten metal at a sufficiently high velocity. When supplying molten metal at a constant volumetric flow rate (e.g., to avoid fluctuations in casting speed), the nozzle can be crafted to have a smaller-than-standard diameter opening, thus generating a higher-than-standard velocity jet.Type: ApplicationFiled: February 27, 2018Publication date: August 30, 2018Applicant: Novelis Inc.Inventor: Samuel R.
