Combined with practical production experience, taking the rail products of seven racks universal production line as an example, this paper studies and deduces the pass design method of the universal zone. According to the finished product size, each pass's elongation coefficient, the local size deformation relationship of each pass, the cross-sectional area, and the elongation coefficient of each pass are inversely calculated. On this basis, combined with the pass design experience, the structural shape and pass the size of each pass are determined. The field application for more than ten years shows that the research results can fully meet the efficient development of high-precision rail and have the characteristics of reducing the number of trial and error of pass design, high design efficiency, high product yield, and high dimensional accuracy and low production accident rate.
