Methods and systems for sorting mixed metal scrap may first determine a sorting attribute of each article of metal scrap, and subsequently mark each article with a machine-readable or visually identifiable mark according to the sorting attribute. The articles of mixed metal scrap can be sorted along a high throughput conveyance using a series of sensors to scan the articles for the machine-readable marks, and rapidly sorting marked articles to appropriate sorting destinations based on detecting the machine-readable marks, and without requiring repeat identification by metal analyzers at the sorting step.

Continuous rapid metal sorting via machine-readable marking

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.
