Application Summary AI generated

This standard specifies a test method for determining the low-temperature reduction-disintegration index and degree of metallization of iron ores used as feedstocks in shaft direct-reduction furnaces. It is applied in the mining and metallurgical industries to evaluate the physical and chemical behavior of iron ore pellets or lumps during the initial stages of gas-based direct reduction. The test ensures feedstock quality for processes like Midrex or HYL, where ore must resist crumbling and achieve sufficient metallization at low temperatures.
