Numerical Simulation of TC18 Titanium Alloy Ingot during Vacuum Arc Remelting ProcessBased on MeltFlow-VAR
The process parameters of vacuum are remelting influence the metallurgical quality of ingot,the complex VAR process can be visualized by numerical simulation,to predicting the rationality of process parameters and guiding actual production.This paper introduces the theoretical control model of electromagnetic field,flow field,temperature field,turbulent mixing of MeltFlow-VAR simulation software.Through simulation the process parameters of Φ820mm standard TC18 titanium alloy,verified the correctness of'model,the pool depth,pool shape,chemical composition distribution,and the temperature field change rule was obtained,It provides theoretical basis for the optimization of process parameters.
