Metallurgical Coal and Coke Testing - SGS

COKE REACTIVITY INDEX (CRI) AND COKE STRENGTH AFTER REACTION (CSR) When coke descends in the blast furnace, it is subjected to reaction with countercurrent CO 2 and abrasion. These concurrent processes weaken the coke and chemically react with it to produce excess fines that can decrease the permeability of the blast furnace burden.
