The Effect Of Minor Components And Flux Additions On The Liquidus Temperatures Of The Multicomponent Iron Silicate Slags

Minor components and flux additions can modify the liquidus temperatures of multicomponent slags. In industrial practice, slags with various levels of minor components require various flux additions in order to achieve the lowest possible liquidus temperature The prediction and the optimization of these combinations can decrease the cost of the overall process. In this work the effect of several minor components and flux additions such as Al2O3, MgO, and CaO, on the liquidus temperatures of multicomponent iron-silicate slags has been analyzed in terms of a thermodynamic model Various simple isothermal and non-isothermal diagrams are presented. These diagrams can be used directly by the process operators to define the optimum conditions under which the fluxes can be used to achieve the desired slag liquidus temperatures.
