Abstract :
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 process. A three-dimensional model including ten pairs of rollers, slab and the contacts between them has been constructed and applied to case studies. The FEM model involving in thermo-mechanical coupling, elasto-plastic and creep is adopted to calculate the deformation of cast slab and the forces of rollers under different roll-gaps. Three typical roll-gaps that are ideal roll-gap, supposed roll-gap 1 and supposed roll-gap 2 are also discussed. The analysis produces outputs such as the load distribution rules of rollers under different roll-gaps. The indications are that the FEM model is rational and analysis outputs provide theoretical reference for the regulation of roll-gap during continuous casting process.
