Application Summary AI generated

GB/T 28702-2012 specifies the technical requirements, test methods, inspection rules, and packaging for nodularizers used in the production of spheroidal graphite cast iron. It is applied in foundries and metallurgical industries to ensure consistent quality of nodularizing agents, which are added to molten iron to promote graphite spheroidization. The standard governs raw material procurement and quality control for manufacturers of ductile iron components, such as automotive parts, pipes, and machinery.
