摘　　要：矿热炉用碱性耐火制品,以镁质砖为主。镁含量不同的镁砖其基质间的硅酸盐相组成和含量也不同,通过对原料的微观结构,成品砖的导热系数、线膨胀及静态抗渣实验的分析,对不同镁含量的镁砖有更清晰的认知。Basic refractory products for submerged arc furnace are mainly made of magnesia bricks.The composition and content of silicate phase between the matrix of magnesia bricks with different magnesium content are also different.Through the analysis of the microstructure of raw materials,thermal conductivity,linear expansion and static slag re-sistance experiments of finished bricks,a clearer understanding of magnesia bricks with different magnesium contents can be obtained.

关 键 词：矿热炉 镁砖 导热系数 热膨胀 抗渣性
