Abstract
The stand-to-stand transmission ratios between the working sizing passes at the entry end of a rolling block for rolling bars, rods or wire are fixed but are different from one another. This enables an entire range of finished workpiece cross sections to be obtained from a given first pass workpiece entry cross-sectional area, merely by omitting one or more of the working stands and shifting other working stands from one location to another and by changing only the stands of the finishing sizing passes at the delivery end of the block.
