摘　　要：用5kg试验焦炉对无烟煤进行配煤炼焦试验,基于无烟煤性质的分析,研究无烟煤粒度和配入量对焦炭质量的影响。结果表明,4种无烟煤性质相近,属易磨中、低热稳定性煤,在烟煤中的容惰能力相差不大;添加3%-5%粒度不大于1mm的无烟煤炼焦,焦炭冷态强度和热态强度分别提高了2.30%和6.03%。Coals blended with anthracite were carbonized in an experimental coking oven of 5kg.Based on the properties of anthracite,effect of the particle size and additive amount of anthracite on coke quality was studied.The results show that four kinds of anthracite have similar properties and inert component capacities in bituminous coal,and their thermal stabilities are moderate or poor.When the dosage of 1-0mm anthracite is kept in the range of 3%-5%,the cold strength and hot strength of coke have increased by 2.30% and 6.03%,respectively.
