“…Pouin et al worked on the longitudinal bowing at the inter distance between the forming stands and their reduction. The results showed that the number of forming stands, the inter distance and strip thickness had the most influence on the longitudinal bowing [17]. Cha et al conducted a study on longitudinal strains and twisting effects on asymmetric cross sections.…”

Since the cold roll forming process is currently used in the production of different sections, it is necessary for manufacturers to further improve the quality of these products. Therefore, it is essential to study various factors influencing the production of these products in detail and provide effective solutions to reduce the factors causing defects in such products. This paper investigates the effect of plastic anisotropy and various factors such as strip thickness, the inter distance between stands, web width, and angle increment on the longitudinal bowing and then compares the results with the practical experiments. Accordingly, a model considering the effect of these parameters on the longitudinal bowing of the final section is considered with the accuracy of 88%. The results show that strip thickness and the increment angle at each stand, and the web width have the most influence on the longitudinal bowing, while strip anisotropy and the inter distance has the least effect on bowing.
