Novelis Inc, based in the USA, has filed a patent application for a system to heat mold corners during the casting process. The inventors listed are Brent Opdendries, Robert Bruce Wagstaff, Ravindra Tarachand Pardeshi, and Samuel Robert Wagstaff.
The application, filed on August 29, 2022, is identified by patent application number 202217049147 A. The international classification numbers for this patent are B22D 11/00, B22D 11/049, B22D 11/11, and B22D 11/115.
According to the abstract published by the Controller General of Patents, Designs & Trade Marks, the patented systems and methods use magnetic rotors to heat molten metal in the corner regions of a mold during the casting of ingots, billets, or slabs. These magnetic rotors are positioned adjacent to the mold corners, raising the temperature of the molten metal in these areas. The increased temperature helps to prevent the formation of intermetallics in the molten metal or reduces their formation.
The patent was published in Issue No. 4/2024 of the Patent Office Journal on January 26, 2024.
