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

由流动引起的壁面剪应力引起的耐火衬里的侵蚀是车间人员在连铸中间包操作中面临的严重问题之一。它会缩短衬里寿命并增加总体运营成本。湍流引起的壁面剪应力是造成中间包内衬侵蚀的主要因素之一。由于侵蚀产生的夹杂物会产生可能导致最终产品报废的表面缺陷。湍流抑制器盒 (TIB) 通过限制湍流区域来帮助降低壁面剪切应力，从而改变流动模式。在目前的工作中，已经进行了三维流体流动研究，以研究流动引起的壁面剪应力。高剪切应力区 (HSSZ) 被视为潜在的夹杂物生成位点。从这些位置注入不同大小的夹杂物并跟踪它们的路径。结果表明，TIB 的形状显着影响流动引起的壁面剪应力和夹杂物去除率。结果表明，采用 TIB 3 排列的中间包在所有壁上都表现出最小的壁剪应力。TIB 2 耦合中间包在底壁起源的小尺寸夹杂物 (<= 80µ m) 和最小去除率（在曲线壁起源的夹杂物的情况下）。
