Abstract:Roll failure mechanism of morgan rolling mill in SCR copper rod production line has been analyzed with the random roll wear model, optimal replacement model and hot-rolled copper rod-rolling piece finite element model constructed. After optimized improvement, the “core” issue of roll failure as the technical “bottleneck” restricting the production of low-cost and high-quality copper rod and in the rolling process of similar production lines has been successfully addressed. Morgan rolling mill features a high availability, good quality of copper rod product, high safety in roll use, few rolling accidents, low roll consumption and low production cost.
