Use of blue dust [email protected]

Blue dust is rich in iron content with low silica and alumina. Yet, it has little use in sintering due to its fine size. A study was undertaken to estimate the quantitative effect of addition of blue dust in the range of 20 40% on the strength of sinter. The other variables studied were coke breeze and moisture in

Blue dust does not effect the strength. The optimum levi (-4: variables for the maximon strength of the sinter produ(A is determined by the method of hexagonal design of experjnent. The results indicate that for a basicity of 1.9 an acceptable quality of sinter can be produced. Blue dust amounting to 40.0% of all the iron

Feb 05, 2019 Blue dust was also used in Iron ore sintering as a sweetener [7]. Huge quantities of Blue dust of various grades is available in the Iron Ore Mines of NMDC Limited. This blue dust as such cannot be used as a feed material for steel production due to its fine nature. This blue dust has to be agglomerated (Sintering and Pelletisation) depending

Iron Ore Sinter an overview ScienceDirect Topics

Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process. Iron ore is typically characterized

Iron Ore Sinter IspatGuru

Jul 15, 2014 Iron Ore Sinter. Iron ore sinter or simply called sinter is usually the major component of a blast furnace iron bearing burden material. Sinter normally consists of various mineral phases produced by sintering of iron ore fines with fluxes, metallurgical wastes and a solid fuel. Coke breeze is normally used as fuel in the sinter mix since it

Sintering: A Step Between Mining Iron Ore and Steelmaking

Jun 11, 2019 World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Iron Ore Sintering: Process: Mineral Processing and

Mar 24, 2017 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.

Ore Sintering an overview ScienceDirect Topics

Apr 02, 2010 Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation. As shown in Figure 14.1, iron ore sintering is carried out in three stages: raw material
