A New Method to Determine Internal Reduction Efficiency during Continuous Cast Bloom under Soft Reduction

Abstract

To clarify the efficiency of internal reduction during continuous casting bloom when the technology of soft reduction is applied, a thermal-mechanical coupled FEM model was developed to investigate the internal reduction efficiency. Basing on the model developed in this article, the area variation of the mushy zone under soft reduction could be calculated. A new calculation method of internal reduction efficiency through the area variation of mushy zone was proposed. The variation trend of internal reduction efficiency as a function of soft reduction amount, calculated by two different methods, was introduced.
