Modern steel grades require constant and reproducible production conditions both in the hot strip mill and in the cooling section to achieve constant material properties along the entire strip length and from strip to strip. Prediction of the temperature in final rolling process always utilizes factors such as the work piece's inner organizational structure, plastic deformation, and it's variations of properties and so on, also as well as physical parameters such as gauge, shape, etc. In this paper, a 3-D finite element model is constructed for the temperature field in a rolling process. The temperature field of strip steel is modeled with a 3-D finite element analysis (FEA) structure, simultaneously considering the distribution of the work roll temperature. Then the distribution of field is simulated numerically. From the model, the temperature contours can be obtained by analysis of the temperature distribution of contact area. Finally, the distribution of temperature in any position at any time can be acquired. These efforts provide the reliable parameters for the later finishing temperature, gauge control and shape control. © 2013 American Scientific Publishers All rights reserved.
