In this study, a steady state simulation scheme was developed to improve the computational efficiency of the non‐steady state three‐dimensional finite element solution for analysing bar rolling processes. To find the steady state solution, an iterative procedure was applied for updating the billet mesh geometry using sectional sweeping technique based on the streamline tracing and three‐dimensional contact algorithm. The developed program was applied to simulations of the three‐mill and round–oval–round multi‐pass bar rolling processes. According to the simulation results, it was found that the developed program offers accurate solutions for simulating the bar rolling processes with better computational efficiency compared to the non‐steady state approach.
