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.

Fig. 1.1 Rolling of a Product in a Rolling Mill. Roll Pass Design Object of Roll Pass Design. Steel sections are generally rolled in several passes, whose number is determined by the ratio of initial input material and final cross section of finished product. The cross section area is getting reduced in each subsequent passes and gr adually the ...
• The rolling unit accommodates a single pass design from stand 1 through the last stand of the finishing block. Used in a combination bar and rod mill, both the Morgan Rod Reducing/Sizing Mill and Morgan Bar Reducing/Sizing Mill are integrated to work with the same single-family pass design. High mill efficiency can be maintained without regard

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.

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability and …
If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. At 114.16 tons/hour that is an additional 10,000 tons can be rolled.
