Influence of Wettability and Reactivity on Refractory Degradation – Interactions of Molten Iron and Slags with Steelmaking Refractories at 1550°C
Refractories, materials that can withstand high temperatures, play an important role in the iron and steel sector which alone accounts for ~70% of total refractories pro‐ duced. In this chapter, detailed wettability and interfacial phenomena investiga‐ tions on alumina-carbon and zirconia-carbon refractories at steelmaking temperatures. The wettability between refractory substrates and molten i...
متن کاملInterfacial Friction-Related Phenomena in Continuous Casting with Mold Slags
Many phenomena in continuous casting including the formation of surface defects are greatly affected by heat transfer in the mold. The interfacial slag layers between the solidifying steel shell and the mold wall dominates the resistance to heat removal and thus controls mold heat transfer. Surface defects, such as longitudinal cracks and star cracks have been associated with variation of slag ...
متن کاملSurface Tension during Molten Metal Granulation
The surface tensions of a number of common commercial ferroalloys have been measured during their granulation in water. These measured values are significantly lower than would be expected from a normal metal-gas interface and are more typical of the interfacial tensions of slag-gas interfaces. This would seem to indicate that the slag-metal interface on the surface of a granule produces no sig...
متن کاملInterfacial Tension of Electrolyte Solutions
A theory is presented to account for the increase in surface tension of water in the presence of electrolyte. Unlike the original “grandcanonical” calculation of Onsager and Samaras, which relied on the Gibbs adsorption isotherm and lead to a result which could only be expressed as an infinite series, our approach is “canonical” and produces an analytic formula for the excess surface tension. F...
متن کامل[Physical properties and metal elutions of the thirteen molten slags produced from incinerated ash].
In recent years, there have been many attempts to reuse molten slag. Molten slag is obtained through further treatment of incinerated ash produced in the disposal process of garbage or sewage sludge and is used in building materials, such as brick. To establish the safety of such slag, its physical properties and metal contents were investigated in this study. After examining the physical and c...
