Interactions Between Molten Iron and Carbon Bonded Filter Materials

AbstractThis chapter presents the interaction between carbon free active and carbon bonded reactive ceramic filter materials and molten iron by utilizing the sessile drop method. The most of carbon free ceramic filter materials showed non-reactive system during the interaction. After the interaction, the number, type, and the size of the non-metallic inclusions were registered with the aid of ASPEX analysis. On the other hand, the carbon bonded materials showed a series of phenomenon during the interaction including the formation of oxide layers covered on the iron droplet and whiskers on the surface of the sample droplets and substrates. To explain these phenomena, the stability of the oxides was calculated. The calculated results indicate that the oxides that consisted of substrates could decompose under the present experimental conditions.
