Abstract

1326809 Making rolls for rolling mills VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE AG 21 Dec 1970 [24 Dec 1969] 60615/70 Headings B3A and B3M In order to prevent slip of working rolls, particularly when shaping steel slabs into prestrips on broad strip mills, the middle portion of the roll has a coarser surface finish than the end portions. In the case of a new roll the middle portion is roughened by sand blasting, and in the case of a worn roll whose middle portion has been roughened by use, the end portions only are machined down to the diameter of the middle portion. This middle portion may extend from one-fifth to one-third of the overall length of the roll.
