摘要

摘要本文对不同成分镁碳砖的抗氧化性能进行了评价，得出了影响因素，探讨了抗氧化性能对镁碳砖性能的影响。试验结果表明:对于低碳MgO-C耐火材料，保温时间的影响大于氧化温度的影响;对于中、高碳镁碳耐火材料，氧化温度的影响大于保温时间的影响。耐火材料的抗氧化性能，特别是低碳镁碳耐火材料的抗氧化性能，随着金属添加剂含量的增加而提高。抗氧化性能随着石墨纯度的提高而提高，特别是在低温区。期望本研究能为炉衬耳槽区镁碳砖的优化选择做出贡献，并为长综合使用寿命耐火材料的设计提供参考。

Oxidation resistance of magnesia carbon bricks and the influence on their performance

ABSTRACT In this paper, the oxidation resistance of magnesia carbon bricks with different compositions was evaluated and the influencing factors were obtained, the influence of oxidation resistance on the performance of magnesia carbon bricks was investigated. The test results showed that for low-carbon MgO-C refractories, the influence of holding time was greater than that of oxidation temperature; for medium and high carbon MgO-C refractories, the influence of oxidation temperature was greater than that of holding times. The oxidation resistance of refractories, especially that of low-carbon MgO-C refractories, improved with the increase of the content of metallic additives. The oxidation resistance improved with the increase of graphite purity, especially in the low-temperature region. It is expected that this study can contribute to the optimal selection of magnesia carbon bricks in the trunnion area of furnace lining and provide a reference for the design of refractories with long overall service life.
