At the finishing train of rod mills, the strain rates reach as high as 1000–3000 s −1 and the inter-pass times are around 10–60 ms. The results show that the proposed model is an efficient tool for evaluating the effects of process-related parameters on product quality and dimensional tolerance of the products in rod (or bar) rolling.
