Abstract

6xxx series aluminum alloys can be processed to produce aluminum alloy products with improved strength while maintaining a high elongation. For example, said processing method can include solutionizing a rolled aluminum alloy product comprising a 6xxx series aluminum alloy. Then, the solutionized aluminum alloy product can undergo a pre-aging step before a cold rolling step. The cold rolling step can reduce the gauge of the aluminum alloy product by 5% to 30%. Then, the cold rolled, pre-aged aluminum alloy product can undergo an artificially aging step that is performed at a higher temperature than the pre-aging. The resultant artificially aged aluminum alloy product can have a yield strength of 375 MPa to 475 MPa and a total elongation of 15% or greater.

The result of the second stage is collected salt and salt-free oxides. After removing the salt-free oxides, residual heat in the furnace and collected salt can be used for a subsequent dross treatment.

Abstract

Described are electrochemical cells incorporating an aluminum-based foil as an anode and exhibiting limited porosity formation during charge-discharge cycling by virtue of an applied stack pressure of greater than or about equal to a yield strength of the aluminum-based foil. Using a battery casing to apply a stack pressure of greater than or about equal to the yield strength of the aluminum-based foil can provide for improved cycling stability due to limiting porosity formation in the anode during cycling despite volume changes that occur. The applied stack pressure enables improved reversibility and mitigation of lithium trapping, improving rate behavior and average Coulombic efficiency of charge-discharge cycling as compared to electrochemical cells subjected to a stack pressure below the yield strength.

Abstract

Systems and associated methods are provided for controlling the shape of an ingot head during formation. At the end of a cast, prior to forming the ingot head, chill bars or other cooling structure may be lowered into an ingot mold and define a reduced casting footprint for forming the ingot head.

As additional molten metal fills the reduced mold footprint, the ingot may be lowered relative to the chill bars to further increase the height of the ingot head. Additional molten metal may be added until the desired shape of the ingot head is formed.

Abstract

Grain size of a deliverable metal product can be improved by pre-setting recrystallization-suppressing dispersoids during casting. The outer regions of a direct chill cast embryonic ingot can undergo reheating before casting is complete. Through unique wiper placement and/or other reheating techniques, the temperature of the ingot can be permitted to reheat (e.g., up to approximately 410° C. to approximately 420° C.), allowing dispersoids to form. Stirring and/or agitation of the molten sump can facilitate formation of a deeper sump and desirably fine grain size as-cast. The formation of dispersoids during and/or immediately after casting can pin the grain boundaries at the desirably fine grain size, encouraging the same grain sizes even after a later recrystallization and/or solutionizing step.

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.

Abstract

Systems and associated methods for controlling roll steering during rolling of a metal substrate may include a steering control actuator adapted to control an inclination of a work roll of a work stand of the rolling mill, a sensor configured to measure a parameter of a metal substrate upstream from the work stand, and a controller operably connected with the steering control actuator and the sensor. The controller may generate a model for the work stand and determine an adjustment value for the work stand, receive the measured parameter from the sensor, and determine an expected output parameter by adjusting the measured parameter by the adjustment value. The controller may also compare the expected output parameter with a target output parameter and actuate the steering control actuator such that the expected output parameter is within a predefined tolerance of the target parameter.

Abstract

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.

Abstract

Provided herein are an aluminum can end stock (CES) and methods for producing CES. The CES includes a laminated metal strip having a polymer film coating and beneficially exhibiting low feathering, low hairing, and high abrasion resistance. The laminated metal strip can include the laminated polymer coating on an exterior-facing side and a lacquered coating on an interior-facing side. The CES is formed by laminating a polymer film to a side of the metal strip and annealing the laminated metal strip. In some cases, the polymer film laminated to the metal strip is a polyethylene terephthalate (PET) film, which may be colored.
