Some experiences in the sintering of iron ores S. JAYARAM, D. D. BHUPTANI, P. MEHTA, and F. W. KOKO AS PART of a 2 m. ton expansion project, the Tata Iron and Steel Company set up an ore-crushing and sintering plant to provide a sized ore plus sinter feed to the blast-furnaces. The sinter plant started operation in late 1959,

sinter made from magnetic concentrates is no longer massive but open and cellular in structure, and deserves a preference for furnace use as compared with natural ores. Silicate of iron, which composes heating furnace cinder and is difficult to reduce in the blast furnace, does not occur in the sinter produced by the continuous down-draft method.

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 fines: The larger sized iron ore fines (> 10mm) does not take part in agglomeration rather is sometimes came un-sintered. The larger sized iron ore will segregate at a particular portion where sintering will be fast leaving behind the other portion. This situation will generate heterogeneous sinter

Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as part of a manufacturing process used with metals, ceramics, plastics, and other materials.The atoms in the materials diffuse across the boundaries of the particles, fusing the

During the iron ore sintering process, two types of particles are present in the sinter bed: (1) fines, which are actively taking part in melting and the formation of secondary phases, and (2) coarse ores, which are partially interacting with the surrounding melt. The quality of the final sinter is particularly determined by the secondary phases and their bonding ability.
