Conclusions
The wear resistance of periclase-carbon articles grade PUÉP-116 in the walls of steel ladles is 1.5–2 times greater than that of mullite-corundum refractories MKS-72.
The feature of the phase inversion of periclase-carbon articles is the formation in the working zone of a dense, spinel-containing subzone which retards the wear of the refractory lining.
The wear of periclase-carbon articles occurs through the gradual replacement of the periclase by the more fusible aluminosilicate compounds of the mellilite and merwinite type, and subsequent fusion of the rapidly slagged surface layer.
