A computational method for pass design of the four-roll rolling process for sizing of round sections. The four-roll rolling process (4RP) enables the further evolution of sizing processes in ...
The traditional approach to the design of the profile of the roll passes is based on subdividing the entire sequence into sub-sequences (Ref 1 ), e.g., diamond-diamond, square-diamond-square, square-oval-square, and round-oval-round (Fig. 1 ). The calculation of the number of passes is then made by considering an average elongation ratio.

Having the strain rate, bar temperature, and grade, we use the graph for the correct steel grade, look for the curves at the temperature closest to case at hand, then look across the x-axis for the natural strain, then up to the curve and across to the flow stress value. This is the flow stress σ we use to determine the separating force. Roll ...
