Corrosion Profile on Boundary Solid Phase – Slag Melt
Interceram 65 (2016)  232-236
The corrosion of refractories constitutes a high-temperature process of solid phase dissolution in the melts. Dissolution is a physico-chemical process with changing chemical composition of the solid and liquid phase. The liquid layer, which is in contact with the surface of the solid phase, is enriched by dissolved matter. This leads to changes in the structure of the melt and also changes to the physical properties in the contact layer, which evokes both vertical and horizontal hydro-dynamical flow in the melt in an effective diffusion layer and this process consequently creates a solid-phase corrosion profile.
Herein we describe the impact of wetting angle, viscosity, melt density, and surface tension under conditions of free convection on the shape of the corrosion profile of the solid surface.
As an example, this paper presents a model of the corrosion profile formed based on experimental measurement of the physical properties of melts of the FeO-SiO2-CaO-MgO system, which have been used for the development of a corrosion profile in the system MgO(s)–[FeO-SiO2-CaO](l).
