Iron ores for blast furnace feedstocks — Determination of low-temperature reduction-disintegration indices by static method — Part 1: Reduction with CO, CO2, H2 and N2
ISO 4696-1:2007 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 4696-1:2007 is applicable to lump ores, sinters and hot-bonded pellets.
