摘要： Apparatus for electric arc treating the surface of a workpiece, the surface having a substantial area. The treating is effected by a continuous, closed loop electrode having a main body portion and a closed tip edge projecting laterally from a general plane of the main body portion for establishing an arc between the tip edge and the workpiece surface. The arc is moved about the continuous electrode tip by magnetic means located in close proximity to the electrode, the magnetic means including a closed loop pole member spaced outwardly of and concentric with the closed loop tip edge. A second pole member of a polarity opposite the outer pole member is located in the general center of the closed loop tip edge.

摘要： Substantial surface areas (10) can be treated by continuously magnetically moving an electric arc (14) on the surface substantially continuously around a general loop direction such as a circle, ellipse or oval and moving the surface so that the arc (14) treats a substantial surface area. The arc treatment can be used to clean or roughen a surface (10) and a reactant or treatment agent (140) can be brought to the arc (14) contact site to alter the surface (130) treated with the arc. Auxiliary treatments for the surface can precede or follow the arch treatment, or both. The invention produces very desirable surface properties including a mild roughness or matte condition suitable even for critical applications such as aluminum lithoplate. Other surface characteristics can include one or more of: capillarity, adhesion, uniform emissivity, stable oxide, cleansed of organic and other coating, matte or whiteness, paintability, and others.

摘要： A process for fabricating an aluminum alloy rolled sheet particularly suitable for use for an automotive body, the process comprising: (a) providing a body of an alloy comprising: about 0.8 to about 1.5 wt.% silicon, about 0.2 to about 0.65 wt.% magnesium, about 0.02 to about 0.1 wt.% copper, about 0.01 to about 0.1 wt.% manganese, about 0.05 to about 0.2 wt.% iron; and the balance being substantially aluminum and incidental elements and impurities; (b) working the body to produce a sheet; (c) solution heat treating the sheet; and (d) rapidly quenching the sheet. In a preferred embodiment, the solution heat treat is performed at a temperature greater than 460 °C (860 °F) and the sheet is quenched by a water spray. The resulting sheet has an improved combination of formability, strength and corrosion resistance.

摘要： Disclosed is apparatus (1) and methods for the stretch forming of an elongated hollow metal section (6), such as an aluminium extrusion. The apparatus and methods use a flexible constraining means (15) which surronds at least a portion of the outer periphery of the elongated hollow metal section (6) to constrain and support the walls of the elongated hollow metal section (6) against the forces produced within the interior of the hollow metal section (6) during the reshaping of the extrusion by the stretch forming operation. The apparatus and methods disclosed herein resist wrinkles, crimps and bulges being formed in the walls of the elongated hollow metal section (6) during the stretch forming and reshaping thereof.

摘要： A composite metallurgical product includes a roll cast aluminum alloy core and a filler material bonded on the core. Assemblies joined by filler material are formed from this product by heating to flow the filler material into joints and subsequent solidification of the filler material in the joints. The composite product is made in several ways, including lamination at roll caster rolls, and lamination or thermal spraying at the exit side of a roll caster. The invention additionally provides for an angulation rolling method for varying percent of cladding on the composite, and a high-manganese aluminum alloy useful as core material in brazing sheet clad with aluminum-silicon brazing alloy.

摘要： A method providing a rolling mill with compensation for changes occurring in rolling parameters that result from changes occurring in mill speed. The rolling parameters are under control of actuators that are connected to receive control reference voltages from electrical controllers. The method includes the step of generating a compensation function that describes the actuator movement required to maintain a rolling parameter at a desired level as a function of mill speed. This compensation function is used during mill speed changes to calculate a compensation value change for each actuator, a change that is required to maintain the parameter at the desired level. The compensation value change is added to a current level of the compensation value to provide a new, updated compensation value. The updated value is converted to a voltage for control of the actuator, and the voltage is added to the reference voltage of an associated electrical controller to provide a total voltage reference for the actuator. The total voltage reference is effective to substantially eliminate the occurrence of error in the controlling process caused by a change in mill speed.

摘要： Process and apparatus for improving fluxing gas dispersion in treating molten aluminum by increasing the fluxing gas surface area. The process includes the use of a molten body of aluminum and a gas dispersing unit in the body of molten aluminum, the dispersing unit having at least two, upper and lower dispersers (rotors) mounted on a shaft extending into the molten aluminum. The dispersing unit is rotated, and simultaneously with the rotating, a fluxing gas is added to the molten aluminum adjacent the lower disperser. The fluxing gas is dispersed by the lower disperser to provide finely divided bubbles and then re-dispersed with the upper disperser to effectively increase the fluxing gas surface area in the molten body.
