摘要
对不同变质程度的5种烟煤进行了5 kg实验焦炉炭化实验.并就单种煤的结焦性与对应焦炭的微晶结构间的关系进行了探讨.结果表明,1/3焦煤焦炭、焦煤焦炭的冷态强度和热态强度较好;X射线衍射(XRD)分析结果表明,肥煤焦炭的炭结构因子(La/Lc)最小,石墨化程度最高.焦炭的真相对密度(TRD)随着La/Lc的增大而减小.
In this paper 5 bituminous coals with different coal ranks were carbonized in the 5 kg experiment coke oven. The relationshipship between the eoking property of single coals and the crystallite structure of the cokes were discussed. The results showed that the quality of the cokes which had been prepared from the coking coal and the 1/3 eoking coal were fairly good. It was shown from X-ray diffraction （XRD） results that the carbon structural factor （La/Lc） of the coke prepared from fat coal was smallest, but the graphitization degree was highest. The true relative density （TRD） of the coke was decreased with the increase of La/Lc.
