Results are presented for mineral and petrographic study of chromite-periclase refractories used for obtaining nickel in RNB arc furnaces under ZF AO GMK Noril’sk Nickel enterprise conditions. The nature and mechanism of refractory breakdown during service is revealed on the basis of studying the chemical and phase composition of reaction zones formed in a refractory, and versions are considered for improving their service life.
