摘要： Described are nosetips for continuous casting of a metal alloy. The nosetip may include a first portion having a first surface parallel to a second surface opposite the first surface. The nosetip may include a second portion having a third surface directed toward an extended first surface. The extended first surface may be in a common plane with the first surface. The nosetip may include a third portion having an arcuate surface connecting the third surface to the extended first surface. The arcuate surface may include a point of curvature at a vertical distance from the extended first surface. The vertical distance may be configured to limit a maximum meniscus height for liquid metal, cast using the nosetip, between the nosetip and a continuous casting surface. Also described are methods of continuous casting a metal alloy at a casting speed of greater than 12 m/min.

摘要： 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.

摘要： A cooling pad for a belt casting system includes a first nozzle arrangement and a second nozzle arrangement. In some embodiments, the first nozzle arrangement includes an elongated nozzle assembly that includes a base defining a receiving area, a first insert positionable within the receiving area, and a second insert positionable within the receiving area. The first insert and the base together define a first elongated dispensing slot. The second insert is adjustable relative to the first insert, and the second insert and the base together define a second elongated dispensing slot. In various embodiments, the second nozzle arrangement includes a plurality of multi-position nozzles, each movable between a base position and an offset position such that the heat transfer rate may be locally controlled across the cooling cavity.

摘要： 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.

摘要： A continuous casting device having multi-stage convergence control is disclosed. Cooling surfaces of the continuous casting device can be articulated in stages, providing individual convergence control to longitudinally spaced-apart regions of the casting cavity. In a proximal region, during which the molten metal exhibits solidification shrinkage, a first convergence profile can be used to optimally account for the solidification shrinkage. In a subsequent distal region, a second convergence profile can be used, such as to provide optimal control of exit temperature of the continuously cast article. Multi-stage convergence control can be achieved through individually articulatable cooling pads or other supports positioned opposite the cooling surfaces from the casting cavity to displace the cooling surfaces and thereby adjust the convergence profile of the casting cavity. Actuation of the individually articulatable cooling pads can effect different convergence profiles along the length of the continuous casting device.
