A computational method for pass design of the four-roll rolling
First, we want to introduce the basic geometry of a flat pass in the 4RP, since it has specific differences from the well-known two-roll rolling process. The roll gap, as shown in Fig. 1, is formed by four rolls, which are inclined at an angle of 90 degrees relative to one another.
