METHOD FOR SURFACING A WORK ROLL FOR ROLLING ALUMINUM SHEET AND WORK ROLL SURFACED BY THIS METHOD

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 properti...

Beschreibung
Zusammenfassung:	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.
