| dc.description.abstract | Sulfur content of steel can be reduced to a lower level with a low content of hot metal, which can be implanted by employing the magnesium injection process in the blast furnace to have an efficient desulfurization of the liquid iron. However, the slag surface tension and viscosity change with the increase of MgS content of desulfurization product.
In this thesis, the melting temperature and surface tension of FetO-SiO2-CaO-MgO-Al2O3-TiO2-MnO-MgS slag with different composition including magnesium sulfide will be first evaluated with the sessile drop contact angle method. The viscosity is then predicted by using the optical basicity ratio model. Furthermore, by applying Pelofsky equation, the surface tension could be calculated with the viscosity values. Finally, the experimental surface tension is correlated with measured values. | en |
