Refractories and Industrial Ceramics | Year: 2015

Results are provided for mineral and petrographic study of phase formation and structural changes in chromite-periclase refractories after experiments for their reaction with slag melt and with slag-nickel melt. A reaction mechanism is established for refractories with melts and it is shown that a metal-slag melt exhibits significantly greater refractory corrosiveness than slag. © 2015 Springer Science+Business Media New York

Refractories and Industrial Ceramics | Year: 2015

Results are provided for mineral and petrographic study of phase formation and structural changes in chromite-periclase refractories after experiments for their reaction with slag melt and with slag and nickel melt. The mechanism and intensity of refractory chemical corrosion during action on it of metal and slag, and slag melts are compared. It is shown that periclase-carbon refractory reacts significantly weaker than chromite-periclase with both types of melts. Presence of carbon prevents mutual diffusion of components and chemical corrosion of periclase-carbon refractories, and this considerably improves their resistance compared with chromite-periclase. © 2015 Springer Science+Business Media New York
