Roll pass design optimisation | SpringerLink
Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is important to optimise RPD including the selection of roll materials. New avenues for optimising RPD are to be found by extracting knowledge buried in the vast repository of industrial records.

COMPUTER SIMULATION OF A NEW TWO-THREADED …
Figure 4 presents the results of modeling the stress state for the new roll pass design. Point stresses in the model mesh are specified. The new roll pass design allows maintaining the constant volume throughout the roll-ing process. The tensile stresses are minimum and do not affect the geometry and internal structure of balls (Fig. 4a–c, e).
Roll Pass Design for Flat 50 × 12 – 16 mm
