Coke Reactivity in Simulated Blast Furnace Shaft Conditions

New research results concerning the metallurgical coke reactivity in the blast furnace shaft suggest that widely used standard method, Coke Reactivity Index (CRI) may not be entirely accurate for estimating coke reactivity in the blast furnace. Researcher J. Haapakangas et al. published a paper in Metallurgical and Materials Transactions B in which this topic is carefully examined. It is proposed that H2 and H2O should be present when the reactivity of the metallurgical coke is measured. The research is part of System Integrated Metal Processes (SIMP) program and RENEPRO project.
