Modeling of Wall Shear Stress Induced Inclusion Transport and Removal in Multi-Strand Tundish

Erosion of refractory lining due to flow induced wall shear stress is one among severe problems that shop floor personnel face in continuous casting tundish operation. It decreases the life and increases overall operational cost. Wall turbulent major factors erosion tundish. Inclusion generation creates surface defects may lead rejection final products. Turbulent inhibitor box (TIB) helps reducing by confining zone hence changes pattern. In present work, three-dimensional fluid study has been carried out investigate stress. High zones (HSSZ) are taken as potential inclusion sites. Different sizes inclusions injected from those sites their paths tracked. found shape TIB significantly affects removal rate. Results indicate with 3 arrangement exhibited minimum at all walls. 2 coupled gives highest rate case bottom originated small size (<= 80 µm) least curve inclusions.
