Roll pass design for the rolling of a 12 mm square. i Lll, Fig. 13. The rolling of a near-square flat of 14 9 mm, using a fast shaping method, and a fluted square to achieve straight edges. If this roll pass design is used, also, for rolling the final square section for rolling near-sqaare flats, a new problem arises.

Gerdau Cartersville was upgraded with the addition of three CS type stands in front of the continuous mill train. In addition, a new cold saw was added into the existing finishing end. The upgrade will allow the mill to increase productivity by optimizing the pass design and improving the section control.

Hot rolling is among the most widely used manufacturing techniques. However, rolling mills are major resource consumers; thus, urgent rationalisation is required in the relevant industrial systems. Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is …

Do a progressive set up. This means jog the material through the first driven breakdown, through the first 1-2 side roll pass, (if your mill configuration has side passes) and into the second driven breakdown, then stop. Many firms jog the material all the way through the entire mill before starting any set up checks.
