“…The SiO 2 -Al 2 O 3 -CaO-MgO systems are of considerable importance for controlling and optimization of metallurgical process. In a previous study, 7) a density calculation model for the SiO 2 -Al 2 O 3 -CaO-MgO system and its subsystems has been proposed by present authors successfully. In the present work, the model will be applied to the prediction of surface tension of molten slag in SiO 2 -Al 2 O 3 -CaO-MgO systems and the model parameters will optimized based on the published reliable data.…”

A calculation model of surface tension for molten slags in SiO 2-Al 2 O 3-CaO-MgO systems has been developed in the present study, based on a statistical modelling approach. A total of 832 experimental data of slags have been critically selected and used for the optimization of model parameters, and the present model has a fairly lower average deviation with 4.60% within the applicable composition and temperature ranges. And also, the composition and temperature dependences of surface tension have been discussed using the model. The results indicate that the surface tensions always decrease with increasing SiO 2 content and increase with increasing MgO content. The surface tension will decrease with increasing temperature. KEY WORDS: surface tension; statistical modeling approach; molten slag; SiO 2-Al 2 O 3-CaO-MgO systems.

“…The density of liquid Ti 2 O 3 was measured by Ikemiya et al under an Ar-H 2 gas mixture (1993); extrapolated to 1600°C, Ti 2 O 3 has a density of 4.0 g/cm 3 . Finally, the density of liquid FeO was taken as 4.4 g/cm 3 at 1600°C based on the measurements done by Xin et al (2019). The resultant calculated densities for the example slags (Table I) are given in Figure 8.…”

The properties of high-TiO 2 slags are markedly different from those of many other metallurgical slags. The objective of this paper is twofold: firstly, to assemble in one document the TiO 2 slag properties, including Ti 3+ /Ti 4+ ratio, liquidus temperatures, heat capacity, density, viscosity, thermal conductivity, and electrical conductivity: all expressed in terms of temperature and composition dependency. Secondly, this paper attempts to correlate published experimentally measured data with theoretically based parameters, which will enable the application of the measured properties to wider slag compositions within the pseudobrookite-TiO 2 slag system. Keywords high-TiO 2 slag, properties.

“…The slag-metal separation could be promoted under higher smelting temperature. Increasing smelting temperature would significantly decrease the viscosity and density of molten slag discussed in the authors' previous papers, 18,19) which improve the fluidity of molten slag and decrease the settling resistance of the iron droplet.…”
