Minerais de fer pour charges de hauts fourneaux — Détermination des indices de désagrégation par réduction à basse température par méthode statique — Partie 1: Réduction avec CO, CO2, H2 et N2

Abstract / scope

ISO 4696-1:2015 specifies a method to provide a relative measure for evaluating the degree of size degradation of iron ores when reduced with carbon monoxide, carbon dioxide, hydrogen, and nitrogen, under conditions resembling those prevailing in the low-temperature reduction zone of a blast furnace.

ISO 4696-1:2015 is applicable to lump ores, sinters, and hot-bonded pellets.
