摘　　要：用于炼钢厂电炉沉降室的耐火材料若在使用过程中出现裂纹、剥落和坍塌,会影响正常生产,存在着较大的安全隐患。通过现场对破损原因进行分析和确认,制定了解决措施,主要包括对耐火材料的材质、烘烤方式进行改进,并对施工方案进行优化。改进后耐火材料的整体使用寿命可以由目前的1年提高至5年,成本可节约80万元左右。If the refractory material used in the settling chamber of a steel plant cracks, peels off, and collapses during use, it will affect normal production and also pose significant safety hazards. Through onsite analysis and confirmation of the causes of damage, solutions have been developed, which mainly include improving the refractory material and baking method, and optimizing the construction plan. The overall service life of the improved refractory material can be increased from the current 1 year to 5 years, and the cost can be saved by about 800 000 yuan.
