| Popis: | Ladle-treatment slags are primary wastes from steel production. Slag utilization is prevented by its spontaneous decomposition as a result of polymorphic transformation of dicalcium silicate with decrease in slag temperature. At OOO NLMK-Kaluga, the slag is stabilized by the introduction of boron oxide in the high–magnesia flux during ladle treatment. Industrial tests indicate stabilization of the slag and the formation of a protective layer on the lining, preventing slag corrosion. |
