Conclusions
We recommend utilization of (15±2)% graphite kish (a waste product of metallurgical industry) as a polyphase material containing carbon and an antioxidant for producing periclase-carbon refractories.
The presence of graphite kish facilitates low-temperature densification of the structure of the products.
In the specimens containing graphite kish, a positive effect is obtained due to three factors, viz., the presence of an antioxidant in their composition, intensified evolution of a dense structure of the products during the process of heat treatment, and decreased degree of decarbonization.
Wide application of the graphite kish-containing periclase-carbon refractories in the linings of steelmaking furnaces makes it possible to improve their service life and to solve an important problem of National Economy, namely, to develop waste-free technological routes in certain ferrous industries.
