The paper analyses the mechanism of the damage of furnace hearth and acknowledges that the mechanical washout of molten slag and iron is the crucial factor for the breakout of modern furnace hearth. Nowadays the overdue corrosion index of carbon bricks is the main cause of hearth break. The elongation of hearth life is based on the improvement of refractory material quality.
