Mar 15, 2015· Use of sized sinter is desirable for the improvement of production rates in the blast furnace. Further, crushing the sinter to 30 mm size at the sinter plant yields a more stable sinter because the smaller size fractions are more resistant to degradation. A supervisory station controls all steps of the sintering process.

PDF | Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry ...

as feed to blast furnaces. These ore fines are agglomerated typically through sintering or pelletization to improve the blast furnace burden permeability, reducing the coke consumption rate and improving reduction rate. Sinter is used as blast furnace feed at percentages of up to 90%, and contributes to reduced operating costs (Kogel et al., 2006).

The invention provides a harmless process method for chrome slag by utilizing metallurgy sintering and a blast furnace. In the method, chrome slag to be processed is taken as a raw material, coal dust or coke powder is taken as reducing agent, and adhesive serves as additive to prepare into a spherical core; the raw material of sinter ore or pellet ore is utilized to prepare into a spherical ...

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...

In a blast furnace, iron ore reacts with hot coke to produce pig iron. The sintering or pelletising process prior to the blast furnace operation is added to allow blending of iron ores and also to control the size of the blast furnace feed. Sintering or pelletising improves the blast furnace operation and reduces energy consumption.

super-fluxed sinter in order to incorporate the lime required for fluxing the acid constituents during the smelting inside a blast furnace. Other parameters which has influence on the coke rate and blast furnace productivity are (a) reduction properties (RDI/RI) of sinter, (b) Fe content in the sinter, and (c) fines in the sinter.

Increasing amounts of roll scale, ore fines, return fines, and blast furnace slag were most beneficial to feed permeability, sinter bulk density, and strength. Burnt lime additions improved feed permeability but were not beneficial to sinter strength or bulk density. Sinter …
