ActiveIron ore pellets for blast furnace feedstocks—Determination of the free-swelling index
高炉用铁球团矿 自由膨胀指数的测定
Application Summary AI generated
This standard specifies the test method for determining the free-swelling index of iron ore pellets used as blast furnace feedstocks. It is applied in the iron and steel industry to evaluate the volume expansion behavior of pellets under reducing conditions at high temperatures, ensuring they maintain structural integrity during the smelting process. The standard is critical for quality control in mining, pellet production, and blast furnace operations to prevent operational disruptions caused by excessive swelling.
