Design of ESR Slags According to Requested Physical Properties; Part 2: Density and Viscosity

Density and viscosity components of multifunction Γ(T,ρ,η,к) which for requested working temperature (T), density (ρ), viscosity (η) and electrical conductivity (к) defines all six-component (CaF₂, CaO, MgO, AI₂O₃, TiO₂, SiO₂) slags of requested properties have been defined. The seven parameter correlation parameters describing molten flux density were calculated using Gauss-Jordan multivariable regression analysis approach and literature data. Mills and Sridhar method for estimating molten flux viscosity, has been used. The brute force algorithm for solving Γ has been updated and tested. Our results showed, despite of the exploratory nature of our work, that the calculated compositions included slags manufactured at American Flux & Metal, both: containing fluorspar and those composed only of oxides. The developed numerical algorithm for solving multifunction Γ is powerful enough to give us solutions in reasonable time so in the future additional components of ESR slags (MgF₂, MnO₂, LaF₃, La₂O₃, and ZrO₂) will be also included in the set of solutions.
