| 摘 要： | 针对昆钢高炉使用的耐火砖，进行了K，Na，zn，Pb单独和混合作用的侵蚀实验，考察了时间、温度对侵蚀的影响．由实验确认：自焙碳砖和石墨碳砖抵抗有害元素侵蚀性能比复合棕刚玉砖更优越；K，Na侵入复合棕刚玉砖和自培碳砖的适宜温度区间为800～1000℃，而对石墨碳砖K，Na的侵入与温度呈正相关关系；较低的实验温度更有利于Zn对砖体的侵蚀，温度对Pb的侵入影响不大．砖体内有害元素含量均随侵蚀时间的延长而增加．

| Abstract: | The erosion experiments of K,Na,Zn and Pb to refractory bricks used in blast furnaces of KISCO are performed separately and combinedly to determine the effects of temperature and time on erosion by these hazardous elements.The following results are shown through the experiments: selfbaking carbon bricks and graphite carbon bricks are better to resist erosion of hazardous elements than corundum bricks;the favorable temperature erosion range of K,Na on composite brown corundum bricks and selfbaking bricks is ... |
