主焦煤配入比例对焦炭热反应性的影响

Influence of Blending Ratio of Prime Coking Coal on Coke Thermal Reactivity

在40kg焦炉上进行了多方案的配煤炼焦试验,并对单种煤及配合煤炼焦的焦炭热反应性进行了分析,结果表明,单种焦煤炼焦时25JM的反应后强度最好;配合煤中控制主焦煤的配入比例,适当配入14SM、1/2ZN或26FM后,焦炭的热反应性比单种焦煤炼焦的效果好。

Coal blending coking test for many proposals have been made on 40kg test oven and analysis on coke reactivity from single kind of coal and coal blend has been made. The results show that when single kind of coking coal is used for eoking, after reaction strength of 26JM is better; in coal blend the blending proportion of eoking coal is controlled, after 14SM, 1/2ZN or 26FM are properly blended, its result in coke thermal reactivity is better than coking of single coking coal.
