The thermal–mechanical and microstructural model for the FEM simulation of hot plate rolling

Abstract This paper deals with the modeling of heat transfer, metal flow and microstructure evolution during the hot rolling of steel plates. For computer simulation a finite-element code of program Elroll is used. The Elroll code is based on a rigid–plastic flow formulation coupled with the finite-element solution of the convective diffusion equation of heat transport. To describe the process of recrystallization, precipitation and grain growth for the austenite phase, a semi-empirical equation was used. The presented program was applied to the modeling and design of the multi-pass reverse rolling of hot steel plates. The results of simulation was compared with results from the actual rolling process.
