BS ISO 4696-1:2007

Iron ores for blast furnace feedstocks. Determination of low-temperature reduction-disintegration indices by static method. Reduction with CO, CO2, H2 and N2 | Status: Revised, Superseded, Withdrawn

1 Scope This part of ISO 4696 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. This part of ISO 4696 is applicable to lump ores, sinters and hot-bonded pellets.
