Conclusions
The investigation of the service conditions for periclase-chromite refractories in the roof of the electricarc furnace RKZ-10.5 RRN-1 and their examination after service established the causes of the low roof resistance, and suggested measures aimed at improving the life.
The most effective turned out to be creating an annular design for the roof using shaped articles PKhSÉ-3 and PKhSÉ-5 which at the present time are being introduced for all arc furnaces at the Chelyabinsk Electrometallurgical Combine.
