【摘要】 对洁净钢冶炼钢包用无碳耐高温材料渣侵蚀后的显微结构进行了分析,得到钢包精炼熔渣与Al₂O₃-MgO（SP）耐高温材料的反应产物主要有钙黄长石（C₂AS）、钙长石（CAS₂）、六铝酸钙（CA₆）。分析其损毁机理主要包括熔渣与耐火材料的反应、熔渣在耐火材料中的渗透以及钢液在耐火材料中通过裂纹的侵入,提出了延长洁净钢冶炼钢包用无碳耐高温材料寿命的技术方向。更多还原

【Abstract】 The microstructure of Al₂O₃-MgO（SP）non-carbon refractory after slag erosion in clean-steel refining industry was analyzed. The results showed that C₂AS,CAS₂ and CA₆ were produced when the slag reacted with Al₂O₃-MgO（SP）.The destroying mechanism of the refractory in steel ladle was revealed as the reaction between the slag and the refractory,the invasion of slag into the refractory and the invasion of the steel liquid into the refractory through the crack.Accordingly,extending the life-span of non-carbon refractory is becoming the research trend.更多还原
