DESIGN OF ESR SLAGS ACCORDING TO REQUESTED PHYSICAL PROPERTIES; PART 2: DENSITY AND VISCOSITY

摘要

Density and viscosity components of multifunction Γ(T, ρ, η,κ) which for requested working temperature (T), density (ρ), viscosity (η) and electrical conductivity (κ) defines all six-component (CaF_2, CaO, MgO, Al_2O_3, TiO_2, SiO_2) 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 T 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 (MgF_2, MnO_2, LaF_3, La_2O_3, and ZrO_2) will be also included in the set of solutions.
