TITLE : PHOENICS IN THE METALLURGICAL INDUSTRY PARTICLE SEPARATION IN A TUNDISH

BY : CHAM Consultancy Team - M T Madhav
FOR : Hoogovens
DATE : 1991
PHOENICS Version : 1.5.4

DETAILS :

• Three-Dimensional, steady flow
• Geometry shape represented by porosities
• Algebraic Slip Model incorporated to represent different phases
• Model used to predict particle separation performance in terms of those rising to the surface and those leaving through the outlet

NOTES :

• Liquid steel is poured into the tundish through the inlet at the top
• Impurities in the form of particles rise to the surface
• Purified liquid steel exits through the outlet at the bottom
• Two conditions considered : 1. Tundish with dam and weir 2. Tundish without dam and weir

  Pictures are as follows :

  1. Surface contours of particle concentration - WITHOUT DAM AND WEIR - Particle size 30 microns, concentration 0.8

  2. Surface contours of particle concentration - WITH DAM AND WEIR - Particle size 30 microns, concentration 0.825

  Surface Contours : WITHOUT DAM AND WEIR
  Surface Contours : WITH DAM AND WEIR
