| Abstract: | The ingot quality of vacuum arc remelting process is depending on the operational parameters.The effect of operational parameters on the solidification during vacuum arc remelting process can be appraised effectively by computational modeling.The computational simulation on the profile of molten pool,fluid motion,temperature distribution within the molten pool and the development of grain structure is introduced in detail in this paper.The simulation results were good agreement with experimental results. |
