The function of the Sinter Plant is to supply the blast furnaces with sinter, a combination of blended ores, fluxes and coke which is partially 'cooked' or sintered. In this form, the materials combine efficiently in the blast furnace and allow for more consistent and controllable iron manufacture. Figure 1 shows a simplified diagram of a ...
In normal sintering operations for preparing feed for the lead blast furnace, lead concentrate is mixed with slag, return sinter, and fluxing agents and the mixture is pelletized and sintered. The mixture consists of approximately 25 pct high-grade lead concentrate, 50 pct return sinter, 15 pct slag, and 10 pct fluxing agents, dusts, etc.
In ferrous metallurgy sintering is the thermal preparing process that permits the conversion of fine particles of iron ores under the action of heat into a material suitable for use in blast furnace (Figure 1).

Therefore, measures that lead to reductions in the consumption of fuel and carbonate fluxes will result in abatement of direct emissions of CO 2 from sinter plants. No doubt, reductions in electricity consumption for example to drive the downdraught and cooling fans during sintering will also result in the reduction of indirect CO 2 emissions ...

This sintering cycle contains a heating stage, sintering stage and cooling stage. During these three stages, detailed controlling parameters could be proposed, such as heating rate, sintering temperature, cooling rate and mode, initial and final cooling temperature, which have significant effect on the crystalline state of the material.

The energy consumption in sintering process is about 10%–15% of the total energy consumed in iron and steel companies in China [1], [2], and nearly 50% of the energy consumption in sintering process is carried away by the flue-gas in sintering process and the waste gas in cooling process. ... Therefore, recovering the waste heat …
Sintering Plant: WHRS (waste heat recovery system); steam and power is being generated through heat recovery from sintered ore cooling process In sinter plant during sinter cooling process lot of heat being carried away by the cooling air which is supplied by cooling fans from the bottom of cooler. This heat is being wasted.
Modern sinter plants were developed in 1906 by Arthur S. Dwight and Richard L. Lloyd, and a chain grate strand type sinter machine which was able to operate continuously had been put into operation at Birdboro, Pennsylvania, USA, in 1911 (Vegman et al. 2004).The sintering process gained popularity quickly around the 1950s as …
Therefore, measures that lead to reductions in the consumption of fuel and carbonate fluxes will result in abatement of direct emissions of CO 2 from sinter plants. …
Basic sintering technology. The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger agglomerates. A typical sinter plant consists of a number of sequential operating units with the sinter machine at the heart of the plant.
