Certain aspects of the Nippon Steel Corp. (NSC) based test for measuring metallurgical coke reactivity were studied at the Spanish National Coal Institute (INCAR). It was found that some highly reactive cokes do not follow the correlation between the coke reactivity index (CRI) and the coke strength after reaction (CSR) observed in most metallurgical cokes. It was proved that the temperature of the furnace at the beginning of the NSC test is irrelevant to the subsequent determination of CRI and CSR. By starting the test with a hot furnace, the total operation time and energy consumption can be reduced. In addition, a good correlation was found between the NSC test and a simpler and more economical test: the ECE-INCAR reactivity test.
