REDUCED FINAL GRAIN SIZE OF UNRECRYSTALLIZED WROUGHT MATERIAL PRODUCED VIA THE DIRECT CHILL (DC) ROUTE
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.

Described are techniques for making aluminum alloy products and methods for pre-treating aluminum alloys with small molecules, and the resultant aluminum alloy products, in which small molecules including phosphorus-containing organic acid functionality, such as organo-phos-phonic acids, are applied to a surface of an aluminum alloy product to generate a self-assembled monolayer or multilayer of small molecules on the surface of the aluminum alloy product. Mixtures of different phosphorus-containing organic acids may be employed. At least some of the phospho-ms-containing organic acids may exhibit a hydrophilic character, such as by including one or more hydrophilic functional groups. The self-assembled monolayer or multilayer including hydrophilic functionality may advantageously allow the aluminum alloy product to have a good wettability by water and other hydrophilic substances, such as some epoxy adhesives, but also to have a good wet-tability by hydrophobic substances, such as some lubricants.

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.

COOLING SYSTEM FOR DECOATER CYCLONE DUST AND RELATED METHODS
A cooling system includes a sensor and a cooling conveyor. The sensor measures a dust characteristic of dust discharged from a dust cyclone of a decoating system.

A method of cooling dust from a dust cyclone of a decoating system with a cooling system includes measuring a dust characteristic of the dust discharged from the dust cyclone and into a cooling conveyor of the cooling system. The method also includes advancing the dust along the cooling conveyor and cooling the dust at a cooling rate based on the measured dust characteristic.
A method of joining metal substrates includes applying a compressive force to at least two overlapping metal substrates, applying an electric current at a first level, and ramping the electric current from the first level to a second level greater than the first level over a first time period. The method also includes, after the first time period, applying the electric current at the second level for a second time period, and, after the second time period, discontinuing the electric current for a third time period. The method further includes, after the third time period, applying the electric current at a third level for a fourth time period, and ramping the electric current from the third level to a fourth level less than the third level over a fifth time period after the fourth time period.

Systems and methods are described for roll-forming metal substrates. The metal substrates are subjected to induction heating during the roll-forming process by exposure to time-varying magnetic fields, such as by exposure to a rotating permanent magnet, or exposure to laser radiation from a laser source. Heating of the metal substrates allows improved formability or plasticity of the substrate in order to reduce or eliminate damage to the substrate during roll-forming to low bending radius to thickness ratios. Heating of the high-strength metal substrates can also function to temper the substrates and/or improve surface corrosion resistance and form high-strength end products with desirable properties.

A metal casting system includes a master conveyor, a slave conveyor, a cutting device, and a control system. The master conveyor includes a first belt and a first motor, and the slave conveyor is separated from the master conveyor and includes a second belt and a second motor. The cutting device is between the master conveyor and the slave conveyor and selectively cuts a metal product that is conveyed by the master conveyor and the slave conveyor. The control system includes a sensor that detects ends of sections of the metal product as the sections of the metal product move in a downstream direction. The control system also includes a controller communicatively coupled with the sensor. The controller selectively controls at least one of the first motor or the second motor based on the detected ends from the sensor.
A system for heat-treating a coil of metal can include a furnace, an unwinding system, and a quenching system. The furnace may receive the coil of metal and elevate a temperature of the metal to be within a pre-heated temperature range, such as a homogenizing temperature range or an annealing temperature range. The unwinding system may unwind at least a portion of the coil in a heated state in which the metal is within the pre-heated temperature range or before the metal has cooled past a threshold amount below the pre-heated temperature range. The quenching system may receive the unwound portion of the coil from the unwinding device and reduce a temperature of the unwound portion to a within a quenched temperature range within a predetermined amount of time.
