原平气肥煤炼制优质冶金焦的探讨

High Quality Metallurgical Coke Production from Yuanping Gas/fat Coal

为获得低灰、低硫、低挥发分、高强度的冶金焦炭,以山西原平气肥煤为主煤源,配入适量太原西山瘦煤进行20kg小焦炉试验,结果表明,所得焦炭粒度组成较好,工业分析、机械强度等均达一级冶金焦指标。在此基础上,进行了捣固炼焦试验,所得焦炭反应性明显降低,分别由原来的66.5%和71.5%降到47.5%和48.1%,反应强度明显提高,分别由原来的5.22%和3.5%提高到30.5%和29.7%。大焦炉生产应用表明,配入10%原平气煤后,所得焦炭各项性能测定结果较好,达到了降低成本,提高经济效益的目的。

To get high quality coke Yuanping coal was blended with Xishan lean coal for a 20 Kg coke oven pilot test.The results show that the coke quality is good.Its proximate analysis and strength achieve the index of first-grade metallurgical coke.The stamp-charged test was also carried out.The reactivity of coke remarkably decreases from 66.5% to 47.5%,and from 71.5% to 48.1%,respectively.The strength after reaction increases from 5.22% to 30.5%,and from 3.5% to 29.7%,respectively.Large scale coking production sh...
