"In Blast furnace hot liquid metal flow inside the furnace at High temperature and pressure due which hearth wall subjected to both static and dynamic loads. An in-depth sympathetic of the liquid metal flow and heat transfer is crucial in order to identify the key mechanisms for the hearth erosion of a blast furnace. In this Paper CFD analysis of Blast furnace hearth is done by simulating iron flow and heat transfer in the hearth which is governed by Navier- Stokes equation. A CAD model of blast furnace hearth is modeled by using Pro E and which is further imported in ANSYS- Fluent. Where heat transfer and natural convection, a computational fluid dynamic calculation was performed to generate flow field in the hearth and the temperature distribution in the refractories during the tapping process. During tapping process hearth wall subjected to shear stress and heat flux due to Tap hole which is been optimized by varying the position of Tap hole as well as the tap hole orientation which result in positive way by getting declination in wall stress upto 6%. Through this it can be conclude that on varying tap hole configuration effects the hearth wall stress and heat transfer. The obtained result and accuracy of the model are validated and shows good agreement with the literature. "
