Conclusions The use in steel-teeming ladles of a combined lining of periclase-chromite parts in the zone of the metal and periclase parts in the slag belt provided a lining life of up to 14–18 heats and a minimum quantity of nonmetallic inclusions and metallic chromium in teeming of cord steel. During service zone formation accompanied by change in texture, structure, and phase composition of the refractory occurs. Wear of the periclase-chromite parts in the zone of the metal is caused by mechanical breaking away of the dense working layer from the less dense one at boundary with the transition or least changed zone. Wear of the periclase refractories occurs as the result of chemical interaction with the slag with formation of lowmelting compounds with subsequent passage of them into the slag.
