Abstract:With the advancement of the casting process and to meet the demand of the quality, more and more expert and producer have been concerned about the optimization of the mould taper. In this study, thermal-mechanical finite element model is applied to optimize the mould taper of 150 billets. 2D transient conduction equation has been established to simulate the shell growth and shrinkage of the shell;a 3D thermal-mechanical finite element model has been established to optimize the mould taper, Based on this foundation the curve taper mould has been designed. The result shows that when the casting speed is 2.5m/min, multiplicity mould taper should be adopted, and the distortion of the mould makes little effect on the taper of the mould ,the taper of the mould mostly depend on the shrinkage of the shell.
