| 摘 要： | 采用光学显微镜(OM)、扫描电镜(SEM)和能谱仪(EDAX)对AOD炉用镁钙砖的残砖进行了分析,探讨了炉衬镁钙砖的侵蚀机理。结果表明:AOD炉衬镁钙砖的蚀损主要是由硅酸盐液相的溶解和渗透引起的;在残砖反应带和原砖带之间形成的平行于工作面的横断裂纹,是加速镁钙砖损毁的重要因素。 |
| 关 键 词： | AOD炉 镁钙砖 显微结构 侵蚀机理 |

| Abstract: | Residual MgO-CaO brick after being used in AOD furnace was determined by OM,SEM and EDAX. Corrosion mechanism of MgO-CaO brick as furnace lining was studied.Results show that:the corrosion of MgO-CaO brick is mainly owing to the solution and infiltration of silicate liquid phase.Transverse cracks between reacted zone and original zone are parallel to the working face, which is an important factor for quick corrosion of MgO-CaO brick. |
| Keywords: | AOD furnace MgO-CaO brick Microstructure Corrosion mechanism |
