The ores utilized for the sintering experiments are of the type with predominant hematite with a siliceous gangue : The various ores can be classified into three groups : a) Banded hematite ores The most typical among these is that of ITABIRA. It occurs in form of little conglomerated crystals of hematite.

In the actual sintering process, a variety of raw materials, such as limestone and iron ore, are mixed with coal in the sinter mix. Therefore, the formation of NO and SO 2 might be affected by the catalytic effect of the mixed raw materials. Tomas da Rocha et al. [ 8] confirmed the effect of CaO and FeO on the formation of NO in coal combustion.

Iron Ore Sintering Process Flow Diagram Raw materials: Iron ore X, iron ore Y, iron ore Z were domestic ore, while iron ore K, iron ore L and iron ore M were foreign ore fines mentioned in sinter test program. These iron ores were uniformly mixed respectively to reduce fluctuation of chemical. Learn More

The Sintering Process of Iron Ore Fines IspatGuru. Mar 09, 2013Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of …
Jun 24, 2015 Gas Fired Sintering Machine 3.5.1 Dwight – Lloyed Sintering Machine: of iron ore fines is now universally carried out on travelling machine running on a continuous basis. In 1958 large machine in operation was 3.7m in width, 223 m2 area, production 800t/day.
sintering process plays very important role on the fluidity of liquid phase and bonding strength of sinter body. Experimental study of assimilation characteristics of 12 kinds of iron ores were conducted using micro-sinter equipment, and pure reagent simulating tests of assimilation characteristic were also carried

Iron ore sintering is a predominant process for fine iron ore and its concentrate to be applied in the blast furnace process. However, sintering produces a negative impact on the environment. One of the effective ways to reduce greenhouse gas emissions from iron ore sintering is to use CO2-neutral biomaterials for the fuel needs of this technology.
Sintering converts the powdered iron ores into an ag-glomerate, which posseses the necessary strengh and gas permeability for efficient high-productivity blast furnace operation. The process is carried out by wet mixing a care-fully blended mixture of fine iron ores with 3–5wt% of coke breeze and other additives, such as limestone, lime
By contrast, concentrations of Si in iron ores played a significant role in decreasing PCDD/F and PCB emissions in both sinter and dust samples. This study also confirmed the …

sintering, the calculations can give a good qualitative results, especially in the temperature of melting begin and the temperature of 50% shrinkage. The calculations reported in this study can be used to esti- mate the sintering behavior of the iron ores under a certain industrial condition to reduce the extra exper- iments.
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
As part of a 2m. 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.
