Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.

The 10-pass example should be fine if you're running non-notched, postcut mild steel. If the section is notched, precut, or high-strength material, you'll need more passes to achieve desired results. Additional passes allow the material to flow through the mill with less strain. Design the Layout and Roll Tooling

The typical mill layout for such a rolling mill is at Fig 2. The universal roughing and edging mills are reversing multiple pass mills that run in tandem through computerized speed matching. The universal roughing mill is normally a four-roll mill with two driven horizontal rolls and two non-driven vertical rolls.
