| 摘 要： | 根据高炉炉缸在实际生产中的情况,将炉缸内衬划分为有限单元,采用能量平衡原理建立炉缸内衬温度分布模型,并应用于高炉炉缸内衬设计,进而对炉缸的工艺设计做必要的调整优化,以此获得合理的炉缸内衬温度分布。在此基础上,通过实际生产中的内衬温度推测炉缸内衬侵蚀程度,对炉缸内衬的寿命进行预测。研究结果表明:采用了温度场分布设计技术优化的碳砖-陶瓷杯炉缸内衬的高炉,陶瓷杯侵蚀速率很缓慢,推测蒜头状部位的陶瓷杯使用时间可达10 a以上。

| 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 the base of it,the working lifetime of BF hearth lining could be predicted by predicting BF hearth lining corrosion conditions according to thermal couple r... |
