摘　　要：分析了高炉炉缸损坏的机制,认为现代高炉造成炉缸烧穿的关键因素是液态渣铁流动的机械冲刷。当前,炉缸烧穿的主要原因是炭砖的铁水熔蚀指数过高。延长炉缸寿命的关键在于耐火材料质量的突破。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 over- due 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.

关 键 词：高炉炉缸 损坏机制 炉缸冷却 炭砖质量
