RH-Degasser Refractory Corrosion Mechanism by Lime-Silica Slags of Different Basicity

摘要

Results are provided for a laboratory study of the reaction of industrial self-dissociating slag after steel treatment in an OAO NTMK furnace-ladle unit and synthetic slag of the system CaO-SiO2-Al2O3 with five forms of periclase-spinelid refractories produced by enterprises of Gruppa Magnezit in Russia and Slovakia (Slovmag), and also two Chinese producers. Refractory slag resistance is compared, and their mineral and phase compositions are studied before and after testing.
