Abstract
The 30Cr2Ni4MoV steel is used to fabricate rotors for the nuclear industry. It required a high grade of the grain size. For the regular grain growth during solidification process under different thermal conditions, a study was performed to simulate the grain structure in different zones in heavy ingot. Based on the café module in procast software, a numerical simulation was conducted. The simulation results show that if the parameters a2 and a3 are set to 8.9 × 10−6 and 4.5 × 10−6, respectively, then the simulation results are fit to the experimental results. The numerical simulations provides data on the grain morphology and the ratio of the columnar and equaixed areas. The numerical results are useful as the grain structure in heavy ingots can be revealed.
