摘　　要：通过对高钙镁钙材料在VOD炉现场试用和对其残砖的显微结构进行分析,研究了VOD炉渣与高钙镁钙材料的反应。结果表明,白云石材料具有较高的耐高碱度渣侵蚀性、较高的抗热震性和较高的抗机械冲刷能力;试用中氧化镁颗粒的长大使材料的结构进一步致密,且化学和扩散侵蚀不明显。This paper reviews the reaction mechanism of MgO-CaO brick with high CaO content and VODslag through trial use and microstructures analysis of dolomite residual brick in VOD. The results show that dolomite material has higher erosion-resisting characteristics to high pH value slag, higher resistant characteristics to temperature shock and higher mechanical washing. During the trial use, the growing of the magnesia particles resulted in the dense structure of material, and chemical and diffusion erosion was almost invisible.
