Abstract: 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.

Abstract: Described are methods of making an aluminum alloy product. The method includes heating a rolled aluminum alloy product to a first temperature of from 400° C. to 525° C. The rolled aluminum alloy product may include a 7xxx series aluminum alloy. The method also includes maintaining the rolled aluminum alloy product at the first temperature or within 10° C. of the first temperature for a time duration of from 15 seconds to 30 minutes. The method also includes quenching the rolled aluminum alloy product at a quench rate from 0.5° C./s to 125° C./s thereby generating a heat-treated aluminum alloy product. The heat-treated aluminum alloy product exhibits a strain ratio of from 0.3 to 0.8. The strain ratio is determined according to an ASTM G129 and/or ASTM G139 standard test method.

Abstract: 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.

Abstract: 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.
