摘　　要：通过对原料煤可磨性、工业分析、灰成分、煤岩组分、黏结性及结焦性能的研究,结果表明,进口莫桑比克煤为中等灰分、中等挥发分、低硫分、强黏结性的中等煤化程度主焦煤,采用其单独炼焦可以制得冷热强度均较高的优质焦炭.通过与国内生产的优质主焦煤性能指标进行比较,莫桑比克主焦煤具有硫分适中、强黏结性和结焦性等优势,确定莫桑比克主焦煤可以替代国内优质主焦煤进行配煤炼焦.采用70kg实验焦炉进行不同配比的莫桑比克焦煤代替主焦煤的炼焦实验,结果表明,莫桑比克主焦煤可以作为配煤煤种资源进行应用,并在满足焦炭质量的前提下,确定了进口莫桑比克主焦煤的最佳配比,降低了焦炭的生产成本.The results showed that imported Mozambique coal is a kind of coking coal with medium degree of coalifieation, which has medium ash and volatile, low sulfur and strong caking by studying the grindability, industrial analysis, ash composition, coal maceral, the ca- king and coking properties. Higher cold and hot strength coke will be got when it is used alone to coke. Compared with the properties indexes of high-quality coal that was made in domestic, Mo- zambique coking coal has the advantages of moderate sulfur, strong adhesion and caking property and so on. Therefore the Mozambique coking coal can replace domestic coking coal for blending eoking. Through the experiment that Mozambique replaces domestic eoking coal was made under different blending ratio in 70 kg test oven, the results indicated that Mozambique coking coal can be applied as coal blending resources in the company. In addition, the optimal ratio was deter- mined under the premise condition of meeting the quality of coke. It also reduced the coke pro- duction cost by this method.
