Abstract
A method of rolling an initially annular workpiece between forming rolls in which after the forming rolls have been fully advanced they are retracted initially slowly for a predetermined distance. The forming rolls can then be further retracted at a greater speed. The slow retraction reduces the out of roundness of the finished rolled ring.
