DB53/T 639.7-2014
Scope
This section specifies methods for the determination of silica, calcium oxide, magnesium oxide, phosphorus, aluminum oxide, manganese, titanium dioxide, potassium oxide and copper content in direct reduced iron. This section is applicable to the determination of silica, calcium oxide, magnesium oxide, phosphorus, aluminum oxide, manganese, titanium dioxide, potassium oxide and copper content in direct reduced iron. The measurement range (mass fraction) of each component is shown in Table 1. Table 1 Measuring range of each component Measuring range of components (mass fraction)/% SiO2 0.25～10.00 CaO 0.10～10.00 MgO 0.10～10.00 P 0.010～2.00 Al2O3 0.10～14.00 Mn 0.10～5.00 TiO2 0.010～10.00 K2O
