Standard Test Method for Measuring Coke Reactivity Index (CRI) and Coke Strength After Reaction (CSR)

Importancia y uso:

4.1 When coke lumps descend in the blast furnace, they are subjected to reaction with countercurrent CO₂ and to abrasion as they rub together and against the walls of the furnace. These concurrent processes physically weaken and chemically react with the coke lumps, producing an excess of fines that can decrease burden permeability and result in increased coke rates and lost hot metal production. This test method is designed to measure indirectly this behavior of coke in the blast furnace.
