Abstract

The Blast Furnace hot metal constitute and performance were effect by fluidity and fusion of the slag, as a result, BF smelting course was influenced. In the paper, the titanium slag was researched on, one iron and steel enterprise BF slags were detected and analysis by Scanning Electron Microscope (SEM), Energy Disperse Spectroscopy (EDS) and X - Ray Diffraction (XRD), then the CaO·FeO·2SiO₂ and CaO·TiO₂ were tested beside the TiC that is the production of the reduction, at the same time, the residue iron was found in slag. By the thermodynamic calculation with the Factsage, the liquid phase regions contain magnesium titanate were changed when the percent of TiO2 was enhanced. The smelting rate of slag system can be accelerated when the viscosity of the slag can be decreased, so the content of TiO₂ and B₂O₃ should be controlled.
