摘　　要：以太铜大关山矿特级白云石为主要原料，配入４０％辽南一级镁石，用直接电熔法熔炼的电熔镁白云石砂纯度高、密度大、抗水化性强、微观结构好．以此种电熔砂为原料生产的无水树脂结合的全电熔镁白云石（炭）砖，在ＬＤ转炉和ＡＯＤ精炼炉应用取得了较好的使用结果。A spotal grade dolomite from Taigang Daguan Shan Mine and a first grade magnesite(40%) from south Liaoning were used to produce fused magnesiodolomite clinker by direct fusion method. The clinker is characterized by high purity.high density,gnd hydration-resistance and good microstructure,which is fit for being used as starting material to produce water-free resin bonded m]ly-fused magnesia-dolomite-carbon brick for LD converter and AOD refijing furnace.
