Slag analysis requirements

Slags originate from various stages in the iron and steel making process, e.g. blast furnace, converter, basic oxygen furnace/basic oxygen steelmaking (BOF/BOS), electric arc furnace, or ladle.

Slag has a double role: it permits removal of the gangue and allows exchange reactions with the liquid metal, permitting control of the process to keep the desirable elements in the melt while the others are removed.

The analytical requirements in iron and steel laboratories demand elemental analysis for determination of CaO, SiO2, Fe2O3, MgO, Al2O3, K2O, MnO, Cr2O3, TiO2, P2O5, Na2O and S in slags.

Wavelength Dispersive X-ray Fluorescence (WDXRF) is the technique of choice for these determinations because it provides fast analysis with easy sample preparation, i.e grinding and pressing.
