Publication number: 20230413395Abstract: A rotating magnet heater for metal products, such as aluminum strip, can include permanent magnet rotors arranged above and below a moving metal strip to induce moving or time varying magnetic fields through the metal strip. The changing magnetic fields can create currents (e.g., eddy currents) within the metal strip, thus heating the metal strip. A magnetic rotor set can include a pair of matched magnetic rotors on opposite sides of a metal strip that rotate at the same speed. Each magnetic rotor of a set can be positioned equidistance from the metal strip to avoid pulling the metal strip away from the passline. A downstream magnetic rotor set can be used in close proximity to an upstream magnetic rotor set to offset tension induced by the upstream magnetic rotor set.Type: ApplicationFiled: August 31, 2023Publication date: December 21, 2023Applicant: Novelis Inc.Inventors: Antoine Jean Willy Pralong, Peter Knelsen, David Anthony Gaensbauer, Rodger Brown, Michael Kosmicki, David Michael Custers, Natasha Iyer, Robert Bruce Wagstaff, Alp Manavbasi, ChangOok Son, Duane E.

Publication number: 20230226598Abstract: A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.Type: ApplicationFiled: January 23, 2023Publication date: July 20, 2023Applicant: NOVELIS INC.Inventors: MILAN FELBERBAUM, SAZOL KUMAR DAS, AURELE MARIAUX, DUANE E.
