Ore Sintering - an overview ScienceDirect Topics

2010-4-2  Iron ore sintering is a material preparation process employed worldwide in the production of iron and steel. According to statistical data on pollution, sintering plants rank second in terms of toxic emissions, after the incineration of municipal solid waste ( Menad et al., 2006; Remus et al., 2013 ).

Modeling and Simulation of Iron Ore Sintering Process

the sinter varies between 30–42 mm with the initial diameter of granules of 3.2 mm. Particles of raw mixture including iron ore, coke fine, limestone and et al. are pelletized into granules. Typically the mean diameter of iron ore particle is controlled at 3–5 mm. Coarser particle inclines to become the nuclei with

speaking, sinter quality is determined by the mineral com-position and microstructure. The sintering theory of iron ore fines and practical production show that the bonding phases present during sintering process make iron ore fines bond together. It is worth noting that among these different bond-ing phases, complex Silico-Ferrites of Calcium and Alu-
