APPARATUS AND METHOD FOR IMPARTING SELECTED TOPOGRAPHIES TO ALUMINUM SHEET METAL
A method for surface treating work rolls to produce isotropic textured aluminum sheet features shot-peening the surface of the working rolls that produce the sheet. The media may be steel balls, such as ball bearings or other media, such as glass or ceramic balls, depending upon the optical properties desired for the aluminum sheet, e.g., in terms of diffuseness or brightness of reflection. The various parameters of shot-peening can be varied to accommodate given properties of the roll, such as hardness and existing surface texture to achieve a given desired surface texture. A sheet surface with target properties and the work roll processing needed to produce it may be generated by computer modeling.

APPARATUS AND METHOD FOR IMPROVING MAGNETO-HYDRODYNAMICS STABILITY AND REDUCING ENERGY CONSUMPTION FOR ALUMINUM REDUCTION CELLS
An apparatus and method for smelting has a smelting pot for containing electrolyte, alumina and a layer of liquid aluminum. A wall in the form of one or more TiB2 or alumina plates extends from the bottom of the pot to a height exceeding the height of the liquid aluminum layer formed in the bottom of the smelting pot during smelting. The wall partitions the bottom of the pot and impedes movement of the aluminum under the influence of MHD forces, diminishing the maximum crest height of waves in the aluminum and allowing a reduction in the ACD to reduce electrical resistance and power consumption. The wall may equal or exceed the height of the anode and may, when conductive, act as a cathode, drawing a horizontal current. The wall may be composed of alumina, e.g., in the form of blocks, undergoing electrolytic reduction and being replaced periodically.

The polycrystalline cutting material can comprise a diamond material. The insert can cut an aluminum ingot slice to a surface roughness finish in the range of about 7-9 micro inches.
