1302841 Rolling strip; making rolls USS ENGS & CONSULTANTS Inc 19 Jan 1970 [17 Jan 1969] 2551/70 Headings B3A and B3M A work roll is formed with a surface roughness measured by a stylus method of 20-400 microinches, for example, by electro-erosion. The depressions are formed of uniform shape and depth and have a generally frusto-spherical shape. The roll is used for cold rolling steel strip and may co-operate with a similar work roll to deform each side of the strip. The roll may be roughened more than desired and then brushed or smoothed.
