Abstract
The liquidus temperature of CaO-SiO2-Fe2O3-TiO2 slags was studied using the HTCLSM and high temperature equilibration and quenching method in this work. Furthermore, Raman and XPS spectra of quenched slags with various TiO2 content under the same superheat degree and the CaO-SiO2-Fe2O3-5wt%TiO2 slag at different quenched temperatures were studied to reveal the structure characteristics of the slags. From the HTCLSM and quenched experiment, the slag liquidus temperature decreased with adding TiO2. The analysis results of Raman and XPS spectra indicated that TiO2 could depolymerize the slag network structure under the same superheat degree by increasing the fraction of free oxygen, forming new weaker Ti-O bonds and reducing the quantity of complex silicate units. The increase of the superheat degree could also decrease the polymerization degree and simplify the structure of CaO-SiO2-Fe2O3-5wt%TiO2 slags, which could decline the complexity of structural units and promote the transformation of polymerized units from complex to simple.
