ActiveIron ores for blast furnace feedstocks—Determination of low-temperature reduction-disintegration indices by static method—Part 1: Reduction with CO、CO2、H2 and N2
高炉炉料用铁矿石 低温还原粉化静态试验 第1部分：与CO、CO2、H2和N2的反应
Application Summary AI generated
This standard specifies a static test method for determining the low-temperature reduction-disintegration indices of iron ores used as blast furnace feedstocks, using a gas mixture of CO, CO2, H2, and N2. It is applied in the mining and metallurgical industries to evaluate the physical stability of iron ore pellets or sinter under reducing conditions at low temperatures, simulating the upper zone of a blast furnace. The test helps predict ore behavior during reduction, ensuring feedstock quality for efficient blast furnace operation.
