1.The practice showed that the blast furnace slags mainly consisted of melilite, cuspidine, bivalent metallic sulphide and Ce-Ca silica.
结果表明：黄长石、枪晶石、二价金属硫化物、铈钙硅石是构成高炉渣的主要矿物。
2.Inclusions in the gray strip defects consist of MgO and trace melilite, which result from MgO-C refractory in slag line.
灰色条带状缺陷中外来物主要为氧化镁，并含少量黄长石，来源于渣线镁碳砖耐火材料；
