Abstract

Rails are produced by several rolling processes. These processes play an important role on the performance of rails. We analysed the rolling processes by finite element code, DEFORM. The distributions of temperatures and effective strains are obtained. After the rolling processes, the rails are sent to the cooling bed. During the cooling, the rails are bended and twisted. These bending and twisting should be minimized to produce a high quality rail. The analyses of cooling processes and residual stresses produced through the rolling processes will be Presented in the next paper.
