High ferrotitanium prepared directly by the thermite method has a disadvantageously high O content (≥ 10 wt%) because of the short slag-metal separation time. In this study, CaO and CaF2 are added to the melt to improve the basicity of the slag and melt separation under heat preservation is performed to strengthen slag-metal separation. The thermodynamics of the step-by-step reduction process of TiO...
Ferrotitanium is used as a deoxidizer and alloying agent during steelmaking process, which has a high demand for sulfur control. Sulfur was introduced from raw materials in the process of producing ferrotitanium by thermite method, where CaO was used as fluxing agent. At the same time, CaO has a great desulfurization capability. Effects of CaO addition on the distribution of sulfur in high titanium...
