Present Status and Technical Advances of Steelworks Lime for Basic Oxygen Furnaces in Germany

Source

The effect of chemical analysis, grain composition, and reactivity of lime on slag formation and metallurgy of steelmaking is discussed. Test showed that reburning of soft burn lime may occur in the BOF. By using special lime, which is manufactured from lime and fluxes, it is possible to work against reburning and C2S-formation. The acceleration of lime dissolution and the resulting improvement of the metallurgical reactions lead to a reduction of the blowing time.
