Physical properties of BOS slags

The extant data for the physical properties of BOS slags and for slag systems relevant to BOS have been collated and evaluated. Data for the following physical properties have been reviewed: phase equilibria, viscosities, densities, electrical conductivities, thermal conductivities, and the surface and interfacial tension between the metal and slag. In addition, various mathematical models have been developed for the estimation of the liquidus temperature, density, viscosity, surface tension, heat capacity, and enthalpy of slags. The efficacies of these different models have been evaluated and their reliability in predicting physical property for molten BOS slags has been assessed.
