摘要
通过在反应气中加入氢气，研究此种气体组成条件下，喷补料抗CO侵蚀能力．同时，探讨一种用混合气体来检测耐火材料抗CO侵蚀能力的标准．结果表明：添加氢气促进了CO对喷补料的侵蚀；在95％CO＋5％H2气氛中反应24h与试样在纯CO气氛中反应200h取得相的结果；可以用95％CO＋5％H2代替纯CO气氛，进行耐火材料抗CO侵蚀能力的检测.
The resisting ability of gunning material for blast furnace to CO corrosion was invesitigated under the pure CO and the mixed gas condition through adding hydrogen into pure CO. A standard for testing the resisting ability of refractory to corrosion with mixed gas instead of pure CO has also been discussed. The results showed that the addition of hydrogen acclerates the CO corrosion on gunning material and the corrosion degree of refractory with the pure CO,200 h is same as that with the 95%CO + 5%H2, 24 h. So, It is reasonable to use 95%CO + 5%H2, 24 h instead of pure CO, 200 h to test the resisting ability of refractory to CO corrosion.
