Numerical Simulation on the Microstructure of Small Electroslag Remelting Ingot

Abstract:

Article Preview

The technological parameters determine the metal pool profile and the grain size and orientation in the electroslag remelting process, and thus affect the quality of the final ingot. The microstructure in the small electroslag casting process was simulated by CA method by means of the software MATLAB. Along with the remelting process, the columnar grain begins to grow to certain angle with axles, the shape of the metal pool gets closer to paraboloid shape. Improving the slag pool temperature or increasing the coefficient of heat transfer at the bottom or decreasing the coefficient of heat transfer at the side can lead the axial trend of grain growing to increase and the depth of the pool to shallow, otherwise can lead the trend of grain growing to radial direction to increase and the depth of the pool to deep.
