Roll Pass Design for Round Bars

 — In this study, a computer-aided-design (CAD) system to support roll pass and roll profile design of bar rolling, where simple shapes like round and square bars are produced, was developed in order to minimize trial and errors in industry. An interactive design methodology was used in the developed system to provide various design …

Roll pass design optimisation

 — 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 important …

Pass Design

Our design process includes: Developing a preliminary design within the limitations of the rolling equipment. Conducting a rolling simulation reviewing motor loads, torque and throughput. Establishing family tree and product flow drawings. Producing detailed pass groove drawings that include expected bar sizes, reduction factors and groove factors.

Understanding Rolling Process in Long Product Rolling Mill

 — The rolling sequence of a roll pass design is subject to the limitations applied by the rolling load, the roll strength and the torque available for rolling. ... As the rolls wear and the spread of the bar in the pass changes, the rpm of the stands need to be adjusted as the bar area changes. Most modern control systems modify the R-Factor as ...
