Numerical Simulation of Inclusion Behavior in 8-Machine and 8-Strand Tundish
摘要
Abstract
Molten steel in 8-machine and 8-strand tundish was simulated by the software and multiphase flow model, the inclusion behavior in the flow of molten steel in tundish was analyzed, and the size distribution of inclusion with 50, 100, 150 and 200 μm in steel-slag interface were discussed. The removal rates of inclusions with four dimensions in 8-Machine and 8-Strand tundish were quantitative calculated. The results show that the content of the four kinds of inclusions in the 8-Machine and 8-Strand is 0.01％, and the removal rates are 6.5％, 65％, 71.25％ and 88.5％, respectively. It indicates that large size inclusions are more conducive to removal. The gates of No.3 and No.6 setting conducive to the removal of small inclusions, and the gates of No.1 and No.8 setting conducive to the removal of small inclusions.关键词
