Research on Optimization of Flow Field in 60t Tow-Strand Tundish by Hydraulic Model

Abstract:

The original scheme flow behavior of WISCO 60t two-strand tundish was investigated by means of hydraulic model. Optimized scheme was selected by flow field Character analyzing and residence time distribution (RTD) curves analyzing of each scheme. The results show that the dead volume Vd of optimized scheme decreases to 5.33%, reduced by 77.4% compared with the original scheme. The average residence time Ta of optimized scheme increases to 364.5s, increased by 70.5s compared with the original scheme. The optimized scheme favors more reasonable flow field and inclusions removing in the tundish. It is more adaptive than the original scheme for the tow-strand tundish.
