A sinter feed with good permeability from ignition until burnthrough is required for efficient operation of a sinter plant. In this regard it is necessary to consider the widely held and simplistic view that sinter feeds containing iron ores with high ultrafines content have lowpreignition permeability. A number of factors influence the granulation

This paper reveals that obtaining highquality sinter, improved or stabilized by its size and strength, is a challenge to be solved by embracing both the formation of sinter with the strong structure and the optimal mineralogical composition of its bonds during the preparation of the sintering blend. The existing technological schemes of iron ore sintering do not allow producing the sinter ...

Sinter Quality and Process of Sintering Iron Ores. Sinter is normally the major component of the blast furnace (BF) charge burden. Sinter consists of many mineral phases produced during process of sintering of iron ores. The quality and properties of sinter are dependent on the mineral structure of sinter. However, since the sintering conditions are usually not uniform throughout the sinter ...

Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. During the iron ore sintering process in iron and steel manufacturing, an online analyzer can be used to determine the elemental composition of the bulk raw materials in sinter feed. How do these ...

ties of the sinter. Sinter productivity increased with increase in iron ore mean particle size due to increased flame front speed (FFS) and improved bed permeability with lower sintering time. Sinter with iron ore mean particle size of mm (Classifier fines) yielded better sinter strength with lower fines (–5 mm) and lower RDI. Higher sinter strength is due to effective distribution of acicular silico ferrites of .

To improve the sinter properties it is necessary to provide good quality of iron ore fines. Due to depletion of high grade iron ore resources, goethite and limonitic ore content in iron ore fines is expected to increase gradually. Usually limonitic and goethite ore are associated with higher alumina and LOI. The conventional sintering process is one of the well established processes for high quality hematite ore. It .

Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process. Iron ore is typically characterized chemically, physically, and mineralogically. The effect of iron ore .
