Abstract

With the progressive deterioration of sinter feed quality worldwide in recent years, steelmakers need to seek alternatives to mitigate the deficiency of this raw material. Alternatives to make up for this deficit are the use of concentrate, pellet feed and application of pre-agglomeration technologies, such as intensive mixers, pelletizing discs and nodulizers. The possibility of using in the sintering mixture a high grade Brazilian pellet feed, designated as HGPF, which presents advantages compared with the natural sinter feed currently available in the market, such as low alumina and silica contents, suitable surface morphology and mineralogical properties, was investigated. Sintering tests were conducted at SGA (Studiengesellschaft für Eisenerzaufbereitung) laboratory in Germany to evaluate the performance of this product when added to typical sintering mixtures used in Western Europe. The results showed gains in the chemical, physical and metallurgical quality of the sinter produced.

Keywords
