Application Summary AI generated
GB/T 30899-2014 specifies technical requirements, test methods, inspection rules, and packaging for selected luppen used as a high-grade iron raw material in steelmaking and smelting processes. It applies to the production and quality control of granular iron products derived from direct reduction or smelting reduction, ensuring consistent chemical composition and physical properties for efficient furnace operation. This standard is primarily used by iron and steel enterprises in China for procurement, acceptance, and processing of luppen intended for electric arc furnaces or basic oxygen furnaces.
