POSSIBILITIES FOR THE UTILISATION OF STEELMAKING SLAGS FOR THE PRODUCTION OF SLAG-FORMING MATERIALS

The paper presents existing methods and findings of own research on the utilisation of steelmaking slags for the production of slag-forming materials used in secondary steelmaking. The research conducted concerned the possibilities for the utilisation of BOF slag and ladle slag for this purpose. On the basis of calculations and tests performed it has been found that reduced ladle slag of high Al(2)O(3) content blended with lime and bauxite additions can be used for the production of slag-forming compounds. The amounts of lime and bauxite added should be determined on the basis of calculations performed with computer thermodynamic databases.
