Abstract
We describe the development of the technology of periclase-carbon composite refractories with a new complex binder, which combines the properties of phenolic resins and coal-tar pitch. Theoretical analysis and the results of application in steel teeming ladle lining show that a combination of these thermoreactive and thermoplastic components in the new binder provides a more compact (denser) structure of the coke framework (residue) possessing increased resistance to oxidation. Articles made of the new composite refractory have been successfully tested in the lining of steel teeming ladles. The wear characteristics of new lining materials in steel ladles has been studied.
