EXPERIMENTAL STUDY ON THE RESTRICTION IN FLUORINEAND ALKALI CONTENT IN BLAST FURNACE SLAGAT BAOTOU IRON AND STEEL CO

DU Hegui MA Ximing (Northeastern University)  
The experiments showed. the fluorine and alkali content in Baotou BF slag influence seriously on its metallurgical properties with CaF2 as a dominant factor. When CaF2 and (K2O+ Na2O) are decreased to about 2.52% and 0.19% respectively, the viscosity and melting temperature of slag is reduced to the values close that of common BF slag. The good results can be obtained for increasing the surface tension of Baotou BF slag. when CaF2 content in slag is decreased to below 2.5%.
