A two dimensional heat balance model has been formulated to predict the temperature profile in the sub-hearth of an iron blast furnace. The partial differential equation, constituting the model, is solved along with the boundary conditions using the Finite Element Method. From the predicted location of temperature isotherms corresponding to 1150°C, the two dimensional profile of the salamander and its depth of penetration are predicted. Effects of cooling conditions at the side walls and at the bottom of the sub-hearth on the salamander penetration and temperature profile have been discussed.
