Abstract
Specialized carbon-doped spinellide-periclase refractories developed for the bottom lining of a ladle furnace are described. Large-sized PShUP 1-1-grade refractory blocks have been used for the “impingement” zone which made it possible to reduce the conventional wear rate of 6.21 mm per heat to 2.55 – 2.95 mm in the impingement” zone and to 1.09 – 1.66 mm in the hot layer of the bottom lining.
