This paper is concerned with the method for estimating an erosion surface of refractory brick in blast furnace hearth. The boundary element method (BEM) is used combinedly with a cellular automata (CA) method. The meridional cross-section of the blast furnace hearth is divided into a number of uniform cells, and a state variable defined on each cell is altered by local rules and also a transition rule. The cost function is defined as the square sum of differences between the measured and computed temperatures at some selected points on the outer surface. The minimum value of the cost function is searched in an iterative manner. This paper presents a practical guideline for estimation of the erosion line through numerical simulation. It is demonstrated that there is a region of existing erosion lines which can be well estimated from a several mumber of initial shapes of the erosion line by finding the minimum value of the cost function.
