Claims
- 1. A rolled aluminum product having a specularly reflective surface provided by an isotropic surface and texture comprised of a reflective surface area provided with raised prows deterministically formed on the specularly reflective surface of the product by a work roll in a rolling mill deterministically provided with discrete, smooth entry, bowl-shaped depressions into which material of a sheet of aluminum extrudes into and is smeared by action of relative velocities of the work roll and sheet of metal when a massive reduction in thickness takes place in a last stand of a rolling mill producing the rolled aluminum product.
- 2. A rolled aluminum product having at least one isotropic textured surface of micron-sized prows located on reflective surface areas of the rolled product, said product being formed by the method steps of:
- passing aluminum material between two lubricated rotating work rolls of a rolling mill, at least one of the rolls having a textured surface comprised of deterministically located, minute, smooth entry, bowl-like depressions,
- compressing the aluminum material between said rotating work rolls that effects a reduction ratio on the order of 70%, and
- using the compressing step to form transitory prows on at least one surface of the aluminum material and prows that remain on said one surface of the aluminum material after the material exits the work rolls.
- 3. A rolled aluminum product having at least one isotropic textured surface of micron-sized prows located on reflective surface areas of the rolled product, said product being formed by the method steps of:
- passing metal aluminum material between lubricated rotating work rolls of a stand of a rolling mill at a torque capacity of the stand on the order of 3,000 foot-pounds, with at least one of the rolls having a textured surface comprised of deterministically located, minute, smooth entry, bowl-like depressions,
- compressing the aluminum material between the two lubricated rotating work rolls, and
- using the compressing step to form transitory prows on at least one surface of the aluminum material and prows that remain on said one surface after the aluminum material exits the work rolls.
- 4. An aluminum sheet product having a specularly reflective surface provided by a substantially isotropic texture comprised of reflective surface areas and minute raised prows located on the reflective surface, said prows providing the isotropic texture on the surface, and having predetermined, controlled, consistent dimensions in micron-sized ranges, as provided by a work roll of a rolling mill having a mirror finish and discrete, smooth entry, bowl-shaped depressions into which material of the sheet product enters when massive reductions are taken in the thickness of a sheet of aluminum material that forms the sheet product, the entry of aluminum material into the bowl-shaped depressions providing the prows and isotropic prow texture.
