Abstract：Thermal distribution model of BF hearth lining is established on the base of energy balance principle by dividing BF hearth lining into limited units according to operation conditions of BF hearth, which has been applied to BF hearth lining design and necessary BF process design optimizing to achieve reasonable thermal distribution in BF hearth lining. On such a base, the working lifetime of BF hearth lining could be predicted by predicting BF hearth lining corrosion conditions according to thermal couple readings in BF hearth lining during BF operation. The study has shown that corrosion speed of ceramic cup is very slow for the blast furnaces which adopt “Carbon-Ceramic Cup” hearth lining optimized by thermal distribution design technology. It is predicted that the lifetime of ceramic cup at “Elephant Foot” area could be more than 10 years.
