Effect of Thermo-Physical Properties on Solidification Behavior of Large Size High Strength Steel Ingots
The impact of different microsegregation models on solidification behavior of large size steel ingots was investigated.The microsegregation models include the ideal equilibrium solidification equation,the extreme Scheil-Gulliver,and the non-equilibrium equations.Different dendritic solidification equations were used to study the evolution of the properties and the cooling process of a 40 Metric Tons(MT)ingot of a medium carbon high strength steel.Material thermophysical properties were determined by means of thermodynamic softwares FactSage(R)together with various proposed models from the literature and the thermal simulations were done using Thercast(R)FEM code.The results obtained in this study demonstrate the significant influence of microsegregation model on temperature dependent solid fraction profiles,thermophysical properties,thermal field and solidification time needed for the casting of the large size ingot,which ultimately affect the extent of macrosegregation.
