ActiveDirect reduced iron—Determination of metallic iron—Bromine-methanol titrimetric method
直接还原铁 金属铁含量的测定 溴-甲醇滴定法
Application Summary AI generated
This standard specifies the bromine-methanol titrimetric method for determining the metallic iron content in direct reduced iron (DRI). It is applied in the iron and steel industry for quality control and acceptance testing of DRI used as a feedstock in electric arc furnaces or blast furnaces. The method ensures accurate measurement of metallic iron, which is critical for evaluating the reduction degree and economic value of the material.
