焦炭反应性(CRI)和焦炭反应后强度(CSR)的相互关系

Inter-relation between coke reaction index(CRI)and coke post-reaction strength(CSR)

本文对昆钢质量计量检测中心提供的实测焦炭反应性(CRI)和焦炭反应后强度(CSR)数据进行回归分析,得出焦CRI与CSR成反比的规律,CSR越高的焦炭,其CRI越低。根据冶金焦炭技术指标数据,发现当焦炭CRI数值达到一级冶金焦标准时,焦炭CSR也达到一级冶金焦标准;而焦炭CRS达到一级冶金焦标准时,焦炭CRI数值不一定符合一级冶金焦标准,提出过分追求低反应性和高反应后强度是否合理,并对这两个指标的关系在数学推论上进行了探讨。

Coke reaction index(CRI)is an inverse measure of coke post-reaction strength(CSR).Smaller coke reactivity index is,the better Coke post-reaction strength is.For national metallurgical coke standard,when coke reactivity index value meets,coke post-reaction strength is always satisfied.However,for the same standard,based on the Kunming steel's laboratory data,when coke post-reaction strength value meets,coke reactivity index is not guarantied to be satisfied.
