焦炭的性质与高炉对焦炭质量的要求,描述正确的是()。A、炼焦过程中灰分不能熔融,对焦炭中各种组织的粘结不利,使裂纹增多,强度降低,焦炭灰分主要是酸性氧化物B、提高最终炼焦温度与延长焖炉时间,可以降低焦炭挥发分含量C、同一种焦炭的M40与M10两指标之间,并非都有良好的相关关系,亦即抗碎指标好时,抗磨指标不见得也好D、焦炭高温性能包括反应性CRI和反应后强度CSR,两者有较好的相关关系
关于焦炭强度说法错误的有()A、M40指标每升高1%,高炉利用系数增加0.04,综合焦比下降7kgB、一般来说,M10指标好的焦炭能较好的抵抗高炉中各种因素的侵蚀与作用C、焦炭强度可以用冷态强度、热态强度来表达D、焦炭落下强度表征焦炭在常温下抗破裂能力的焦炭机械强度指标
