热回收炼焦和副产品炼焦的焦炭质量变化研究

RESEARCH ON COKE QUALITY VARIATION BETWEEN HEAT-RECOVERY AND BYPRODUCT COKEMAKING TECHNOLOGY

研究了在副产品炼焦和热回收炼焦中，焦炭的结构特性对焦炭质量的影响。与室式焦炉焦炭相比较，热回收焦炉焦炭的质量均匀性较差，正如焦炭反应后强度（CSR）、孔隙和炭结构所展现的。虽然多孔和炭结构影响质量，但孔隙结构对热回收焦炉焦炭的CSR比室式焦炉焦炭的CSR影响大，特别是在热回收焦炉顶部的焦炭。

Coke structural properties influencing coke quality in byproduct and heat-recovery cokemaking are investigated. Compared to slot-oven coke, heat-recovery oven coke is less homogenous in quality, as expressed by coke strength after reaction （CSR）, pore and carbon structure. While both porous and carbon structure influence quality, pore structure has a stronger influence on CSR in the heat-recovery oven than in the slot-oven, particularly coke at the top section of the heat-recovery oven.
