ABSTRACT

With the H-beam gradually accepted by domestic market, sales and output continue to expand. There is increasing user requirement about product performance. It is requirement of that H-beam has comprehensive mechanical properties, which is decided by the raw material and rolling process. The hot rolling process will produce different physical metallurgical phenomena such as work hardening, dynamic recovery and recrystallization. This metallurgy changes decide microstructure and mechanical properties of the final product, which determines the performance of products in a certain extent[1-3]. Therefore, It is necessary that according to the raw material and rolling process, microstructural evolution of rolling process is simulated and analyzed, thus the microstructures and properties are accurately controlled.
