摘要
对顶装焦炉焦炭的冷热强度与焦比和燃料比的关系进行研究。研究结果表明,随着焦炭的热反应性、耐磨强度的下降,焦比和燃料比呈下降趋势,且趋势逐渐变缓直至水平;随着焦炭的热反应后强度、抗破碎强度的上升,焦比和燃料比呈下降趋势,且趋势逐渐变缓直至水平。从而确定了容积3 000m3高炉的适应性焦炭质量指标,为降低铁前成本,保证高炉顺行打下基础。
The relationship of cold strength,hot strength of coke in top charging coke oven and coke ratio,fuel ratio were studied.It showed that with the increase of coke reactivity and abrasive resistance,coke ratio and fuel ratio show drop trend,and the trend gradually becomes slow until the level.The adaptive dices of coke quality in 3 000 m3 blast furnace are confirmed,which lays the foundation for cost reducing before iron production and direct motion operation of blast furnace.
