焦炭反应性及反应后强度试验方法优化

OPTIMIZATION OF STANDARD TEST METHOD FOR COKE REACTIVITY INDEX(CRI) AND COKE STRENGTH AFTER REACTION(CSR)

对焦炭反应性及反应后强度试验条件进行优化,提高样品入炉温度、增加反应前炉子恒温时间、控制制备样品粒度、缩短反应后系统保护时间,可大大提高检测效率。精密度和准确度试验表明:该优化方案快速准确。

The Test conditions for coke reactivity Index and coke The efficiency of detection can be greatly improved by enhancing the strength after reaction are optimized. oven temperature before sample was put in, increasing the constant temperature time of the oven before reaction, controlling the preparation of sample granularity and reducing the system protection time after reaction. Precision and accuracy tests show that： the optimization program is quickly and accurately.
