高炉炉缸用碳复合砖在水蒸气条件下的氧化行为研究
|
摘要
高炉生产过程中,因风口、冷却器操作失误或设备故障等问题漏水现象频发,研究炉缸用耐火材料在水蒸气条件下的抗氧化性能具有很重要的现实意义,通过热重实验结合热力学分析,研究了高炉炉缸用碳复合砖在不同气氛、气体流量、水蒸气含量条件下的氧化行为。结果表明:碳复合砖在水蒸气条件下表现出良好的抗氧化性能;经比较,碳复合砖的抗水蒸气氧化性能远优于炭砖的抗水蒸气氧化性能,在水蒸气条件下能保证高炉的安全生产。
Because of the misoperation or equipment failure of tuyere and cooler error,water leakage phenomenon occurred frequently in blast furnace production process. Therefore it is meaningful to research the oxidation resistance of refractory material used in hearth under the condition of the steam. By thermogravimetric experiment,combined with the thermodynamics analysis,the oxidation behaviors of carbon composite bricks used in blast furnace hearth in different atmosphere,gas flow rate and steam content. The results show that,the carbon composite bricks under the condition of the steam showed good antioxidant properties. By comparison,the steam oxidation resistance of carbon composite bricks is far better than that of carbon brick,that is to say,the carbon composite bricks can guarantee the safety of the blast furnace.
