· Roughly, sintering can be classified into three major processes: (1) solid-phase, (2) liquid-phase, and (3) vapor-phase sintering methods [1], [4]. In the first case, all components of the system are solid through the whole process. This is the case when sintering crystalline and amorphous solids. In liquid-phase sintering, some of the

· The raw materials for an integrated steelworks can be classified into four categories, which are iron ores, fluxes, fuels, and reverts. The characteristics of these raw materials strongly affect the metallurgical properties of iron ore sinter and sinter plant performance. An optimal ore blend design is therefore essential to produce low cost

· The present article reviews the sintering process that the mixture follows, once granulated, when it is loaded onto the sinter strand. There, the sinter mixture is partially melted at a temperature between 1300-1480°C and undergoes a series of reactions that forms the sinter cake to be loaded into the blast furnace to produce pig iron.

· The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel and return fines of the sinter plant. These materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.
