Influence of [Si], [Ti] Content on Fluidity of Hot Metal

Article Preview

The effects of [Si], [Ti] content on viscosity, melting temperature, and flow properties of hot metal were studied in the laboratory in allusion to the feature that hot metal bearing Ti becomes viscous easily. The solubility of titanium in molten iron was calculated with thermodynamic and relationship between solublity and temperature was disscused. The results show molten iron becomes viscous mainly controlled by the dissolution and precipitation of titanium. [Si] has a weakening effect on the solubility of titanium. Titanium will have less influence on the viscosity of hot metal whenΣ [Si+Ti] content is about 0.6 % and [Ti] content is below 0.29%. The choice of appropriate blast furnace temperature is the crux of avoiding hot metal containing titanium becomes viscous, hot metal pit adhesion, slag iron is difficult separation and so on.
