Kinetic modelling of cement raw mix containing iron particles and clinker microstructure
This paper investigated the oxidation of iron particles contained in cement raw mix using stationary electric furnace. Results showed that oxidation kinetic of metallic particles in cement raw mix was limited by diffusion and occurred mainly in the transition zone. Complete oxidation of metallic particles in the raw mix can be achieved at about 800 deg C. This is about 400 deg C lower than that of abrasive slurry. The presence of CaO enhances the oxidation of metallic particles in raw mix. When used as raw mix component, abrasive slurry containing high metallic particles content can significantly influence the clinker minerals chemical composition, morphology and phases ratio. This is due to increased probability of localized high Fe2O3 concentration and consequently increased acidity of the liquid phase.
