Rolling pass schedules leading to round stock generally employ sequences of ovals and rounds such as illustrated in Figure 17.2. 127 The alternating geometry ensures that the width of the entering rod section is less than the width of the emerging rod section which is necessary for roll entry. As a practical matter actual rod cross sections may be "out of round" and not rigorous ovals.
