| 摘 要： | 为提高瘦煤和1/2中黏煤在传统炼焦配煤中的比例,研究了在配煤中添加改质沥青及酚渣对焦炭质量的影响,采用不同配比的改质沥青和酚渣分别进行40 kg小焦炉配煤炼焦试验。结果表明:随着配煤中改质沥青配比的增加,焦炭的块度减小、干基全焦率Kd降低、粉焦率增加、灰分Ad降低,而焦炭硫含量的变化趋势不明显;配入质量分数1%的改质沥青时,焦炭的抗碎强度M4 0达到最大,比空白试验提高0.9%,配入质量分数1%~3%的改质沥青时,耐磨强度M10比空白试验低0.2%~0.3%;配入质量分数4%的改质沥青,焦炭的反应性和反应后强度都达到最佳,分别比空白试验降低7.9%和升高15.7%;酚渣的配入大幅降低了焦炭的冷强度,其不适宜作为黏结剂用于配煤炼焦。

| Abstract: | In order to improve the proportion of the lean coal and 1/2 coking coal in the traditional coking coal blending,a research on the influences of the modified asphalt and phenol residue added to the coke quality was conducted and the different blending ratio of the modified asphalt and phenol residue were individually applied to the blending coal coking tests in a 40 kg coking oven.The results showed that with the modified asphalt ratio increased in the blending coal,the coke lump would be reduced in size,the... |
