Summary

Silicon carbide refractories has been in use in 47% of the industrialized world's blast furnaces since the middle 19709. Applications have ranged from the tuyere bowl to the middle stack. Samples from shutdown furnaces, as well as cores from operating ones, have been obtained from a variety of these installation. The physical and chemical changes have been studied to determine the effect of alkali attack and oxidation on the overall performance of this class of refractories.
