Development of waste-free technology for periclase-carbon refractory production

Results are provided for a study of product nonconformity during manufacture of periclase-carbon ladle refractories and refractory scrap as a potential raw material source. Optimum charge compositions are given with addition of secondary refractories and a production scheme for the manufacture of periclase-carbon refractory objects taking account of existing technology in the OOO Ogneupor magnesium-dolomite refractory workshop. Pilot batches of objects are produced for industrial tests, confirming a lack of deterioration in operating properties.
