Distribution of Draught In A Pass, Roll Pass Design for …

The simplest case for rolling with non-uniform draught is the flattening of a round bar between plain-barreled rolls. If a square bar is rolled hi an oval pass, non-uniform deformation is affected by the shape of the pass [Fig. 1.30 (я)]. A more complex case of non-uniform defoimation is the rolling of an oval bar in a square pass [Fig. 1.30 (&)].
