“…Differentiated interfacial tension values were found, while the other measuring conditions remained constant. A result of this finding was a development, based on the ion slag theory [9] of the so-called surficial property index (WS) for melted slag-forming mixtures [7,10]. Its numerical value depends on the share of individual cations present in the slag (flux) as well as their magnitude and valence.…”

In the present paper, the results from investigations regarding interfacial tensions present at the borders of a liquid aluminum alloy and two selected melted fluxes (mixtures of salts) are presented. The fluxes feature solidification characteristic curves that are very close to each other as well as differentiated chemical compositions. For the comparative investigations, the so-called surface property index (WS) is calculated for both fluxes with the use of the ion theory of slags. The investigations of the interfacial tensions were conducted on a stand that enabled the measurement of the force values accompanying the tearing-off of the probe from the interfacial surface. A very clear relationship between the interfacial tension values and the WS index values that characterize both fluxes was found. An increase in the WS index value resulted in an increase in the investigated interfacial tension values. It was also found that, in both cases under investigation, an increase in the system temperature value resulted in an increase of the values of the interfacial tensions present within. In the conclusion, we state that the metallurgical treatments (for instance, the recycling of the cast metal composite materials by way of component separation) should be conducted with the use of salt mixtures (fluxes) characterized with WS index and melting temperature values as low as possible.

“…The parameters determining the removal of precipitation efficiency will be the viscosity of the layer on top of liquid metal, densities of the contaminant and fluid, as well as the interfacial tensions at the interface of three phases 4,[15][16][17][18][19][20][21][22] . One of the most important parameters determining the effectiveness of contaminants removal into the slag is its viscosity.…”

In the paper results of numerical analysis of KCl and KF contamination particles present in liquid aluminium assimilationto the slag are presented. Authors analyzed contamination particle movement in the slag model, which base on buoyant,capillary, viscosity, Newton and repulsion forces, interfacial tensions at the interface of phases and surface energy during theparticle movement through phases boundary. On the base of the mathematical model computer program was written to makesimulations under different conditions. In the paper results of particle position in the slag for different particle radiuses: 1, 5, 10,20 μm, and constant slag viscosity including velocity evolution are presented. Another approach was used to indicate influenceof slag viscosity on particle and slag penetration depth. During computations selected slag viscosities of 0.0012, 0.0015,0.0018 [kg / m·s] were taken into account. Different comparisons were made for chosen particle sizes. Each examinationtakes into account impact of contamination particle type. Results clearly show that for larger particles slag penetration depth isgreater and viscosity of the slag has an impact on velocity evolution during assimilation process.
