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.

Based on the considerations listed above, production flexibility for meeting demand on a regional scale [] can be maximized using small-volume mini-mills (100,000–200,000 metric tons (MT) of steel per year).However, the efficiency of such plants is largely determined by the type of mill used in the rolling shop and the load on the mill.

Rolling is done both hot and cold. In a rolling mill attached to a steel plant, the starting point is a cast ingot of steel which is broken down progressively into blooms, billets and slabs. The slabs are further hot rolled into plate, sheet, rod, bar, rails and other structural shapes like angles, channels etc. Conversion of steel into such commercially …

The most important issue during the pass design with the multi slit rolling is the shape determination of the grooves called the dog bone pass and the slit pass. The remaining passes, before and after slitting, are most often standard stretching passes typically used for round rolling in a merchant bar mill.
