Influence of Mould Slenderness Ratio on the Solidification of Heavy Ingots by Numerical Simulation

Article Preview

Abstract:

The quality of heavy ingot normally depends on the processing factor and ingot mould type. Based on the ingot mould type only, the quality and solidification process of a 96-ton ingot moulds with different slenderness-ratios have been studied numerically using the software package ProCAST. The results show that the position of shrinkage porosity moves up and the macroporosity in the ingot center increases prominently as slenderness-ratio increasing, meanwhile, the inclusion-floating time through the middle and bottom part of ingot decreases, and A-segregation alleviates as well. The correlation between the quality and slenderness-ratio of the ingot is not a liner relationship, when the slenderness ratio is 1.4, the ingot has better quality.
