The Mathematical Model and Simulation of Macrosegregation during Solidification Process of Super Heavy Steel Ingot

Abstract:

Through establishing solidification-heat transfer mathematical model of the super heavy steel ingot, the temperature distribution at different moments in the solidification process of steel ingot has been simulated. Based on the simulated temperature field and the law of solute redistribution, the carbon macrosegregation in the solidification process has been calculated. The results show that, the complete solidification time of the 600T steel ingot is 68.34 hours, and positive segregation of carbon forms in the ingot head, and the concentration of carbon near the upper axis which is higher than 81 percent of the ingot’s height is over 2 times than the average value.
