Flow prediction in the multi-strand continuous casting tundish of Millcon Steel PLC

The flow characteristics in the multi-strand continuous casting tundish of Millcon Steel PLC were investigated by CFD simulation and physical modelling. The aim of the study is to optimize the residence time distribution (RTD) which results in the better inclusion removal potential and the steel cleanliness. In this research, the 1:3 scale water model of the tundish was established. Tracer injections were computationally simulated using specie transport model and were physically simulated using red dye color mixed with sodium chloride. The flows are characterized by RTD curves which obtained from the tracer concentration measurement at the outlets. The results show that, among all outlets, the outlet in the middle position is critical and has very low of the minimum residence time. The flow modifiers can retard the minimum residence flow time and the mean residence time for all outlets which could promote the steel cleanliness. (c) 2017 Elsevier Ltd. All rights reserved.
