What is Effect of the Depth of the Submerged Entry Nozzle in the Mold on Heat, Flow and Solution Transport in Double-stream-pouring Continuous Casting about?

The effect of the depth of the submerged entry nozzle (SEN) in the mold on the velocity, temperature fields and composition distribution in the solidification zone was investigated for double-stream-pouring continuous casting (DSPCC) processing using the standard k-ε turbulent model. This analysis is based on an axi-symmetric steady mathematical model involving coupled flow, heat and solution transport. The results show that the mixture zone in the liquid pool between the internal and external fluids moves down and the liquid pool becomes deeper when the depth of the SEN in the mold increases. The 2024/3003 aluminum composite ingots were prepared using a laboratory-made DSPCC facility. The measured copper concentration in the cross-section of the ingots for the different depths of the SEN in the mold is in good agreement with that calculated by numerical simulation.
