ActiveDirect reduced iron—Determination of iron(Ⅱ) content—The potassium dichromate titrimetric method after decomposition of sample by ferric chloride
直接还原铁 亚铁含量的测定 三氯化铁分解重铬酸钾滴定法
Application Summary AI generated
This standard specifies the potassium dichromate titrimetric method for determining the iron(II) content in direct reduced iron (DRI) after sample decomposition with ferric chloride. It is applied in the mining and metallurgical industries for quality control of DRI used as a feedstock in electric arc furnace steelmaking. The method ensures accurate measurement of metallic iron content, which is critical for evaluating DRI reduction degree and optimizing downstream steel production processes.
