An apparatus and method for applying an EDT texture to an aluminum sheet has a rolling stand with at least one EDT surfaced roll capable of rolling the sheet at reductions &#x3c;1%. The rolling is conducted with residual or no lubrication and imparts a texture on the scale of about 1 &#x3bc;m to the surface of the sheet at low roll force.

Embossing for electro discharge textured sheet

An apparatus and method for rolling aluminum sheet uses a texture roll to roll the sheet while is it hot and has reduced yield strength. The texture rolling may be used to remediate defects in the sheet at a variety of stages in rolling, and may facilitate subsequent rolling stages.

In a lubricant composition suitable for use in the manufacture of aluminum alloys comprising lubricant base selected from the group consisting of solid lubricants, liquid lubricants, grease lubricants, emulsion lubricants, and dispersion lubricants, the improvement wherein the lubricant composition further comprises: an effective amount of water and surfactant. It is believed that mixing oil with water and surfactant provides a method for uniformly distributing the surface oxide at the meniscus for casting applications. Uniform distribution of the oxide at the meniscus reduces vertical fold formation that can lead to cracks in the aluminum ingot. In addition, the mixture promotes uniform heat transfer around the mold. Uniform heat transfer around the mold allows the solidifying aluminum alloy to stay in contact with the mold longer and form stronger ingot shells. A process for continuous or semi-continuous casting of aluminum alloys via the use of this lubricant composition is also disclosed.

Lubricant for improved surface quality of cast aluminum and method

A process for separating oil from a lubricant composition containing solid particles. The contaminated lubricant composition is mixed with liquid or supercritical CO.sub.2 before the lubricant composition and CO.sub.2 mixture is filtered through a filter medium. The CO.sub.2 is then evaporated, leaving an oil residue. Mixing the lubricant composition with CO.sub.2 before filtration prevents the filter medium from being blinded by solid particles.

Separating solid particles from used lubricant compositions

The fill chamber bore of a die-casting machine is lubricated and prepared for casting by inserting an elongated member into the die-end of the bore while spraying with lubricant. During withdrawal of the elongated member, a conical spray of gas directed toward the die-end drys the lubricant and sweeps vapor and flash, or solder, out of the die-end. The elongated member is preferably a flexible carrier which is guided between the bore and a path between the open die halves lateral to the bore. The lateral path is perferably defined by a tubular member supported by a vertical carriage mounted on a vertical mast for alignment of the flexible carrier with the fill chamber bore when the dies are open. The vertical mast can be mounted on a horizontal carriage moveable along a horizontal bore to preclude interference with normal operation of the die-casting machine. The flexible carrier can be housed in a arcuate chamber pivoted on the side of the fixed platen and swung between the open dies to align the flexible carrier with the fill chamber bore.
