The main refractory for the slag-line of the main trough of a blast furnace, is an Alumina-Silicon carbide-Carbon castable (pouring mix), in which nonoxide raw materials such as silicon carbide and carbon, make a great contribution to improve the service life. But one drawback of these raw materials is that they easily oxidize. So the authors conducted a corrosion study to consider the effect of oxidation, and investigated the correlation between the experimental results and the actual operation results.
