Assessment of the Adequacy of the Model for Determining the Composition and Properties of Final Slag in a Blast Furnace

The correctness of the calculated composition and characteristics of the final slag at a blast-furnace engineer’s workstation is assessed. The developed model accounts for the combined effect of the components of the slag on its properties by calculating the viscosity polytherms in the range of temp...

Zusammenfassung:The correctness of the calculated composition and characteristics of the final slag at a blast-furnace engineer’s workstation is assessed. The developed model accounts for the combined effect of the components of the slag on its properties by calculating the viscosity polytherms in the range of temperatures in the blast furnace. The use of the model is extended to slags with widely varying composition and content such as Al 2 O 3 3–17%; MgO 5–20%; SiO 2 ≥33%; СаО ≥ 33%, TiO 2
