H beam has been widely used in industry and civil steel structure. But there are many key technologies that must be solved in order to produce high quality H-beam. This paper describes an investigation into the rolling technology using MARC software to model reversing rolling process of H-beam and compare the results with PDA data. A FEM model involving in three-dimensional, elasto-plastic and thermo-mechanical...
During the slab continuous casting process, the top frames of the hydraulic segments slope along the casting direction because of their gravity and install error. This slope changes ideal roll-gap into sawtooth shape. Then the fluctuation of roll-gap declines the quality of continuous casting slab. This paper describes an investigation into the roll-gap fluctuation using MARC to model continuous casting...
In this paper, a reasonable creep material model used in FEM analysis for bulging of cast slab was determined based on the comparative results between simulation and experimental data. A thermo-mechanical coupling, creep and dynamic FEM model of continuous casting process has been constructed and applied to case studies. The analysis produces outputs such as the necessity of considering the case slab...
