Abstract

Slag analysis is very important in maintaining the quality standards of metallurgical processes. The chemical structure and the physical features of slag play a very important role in the management of blast furnace (BF) processes, favouring the development of the decreasing reactions and acting as a thermoregulator of the furnace by the adjustment of heat transmission through the metallic bath. In this paper, the following ranges of oxides concentrations were obtained in BF slags by X-ray fluorescence with wavelength dispersion (WXRF): 32.29-35.56% SiO2; 42.41-44.1 % CaO; 12.20-15.63% Al2O3; 0.40-0.85% MnO; 5.38-6.17% MgO; 0.45-0.69% FeO. The calculated basicity index of slags varied between 1.031 and 1.103, denoting the acidic character of slags.
