Furnace. Pig iron and refined iron ore pellets (briquetted iron) can also be used, and because his t method is economic at lower volumes these operations are called mini mills. Plants that use Electric Arc Furnaces can be sited closer to the market. Where market size permits, some degree of product specialisation is practised. 1.2 Raw Materials The production of iron is accomplished by smelting of ores, pellets, and sinter in blast furnaces with subsequent refining of molten iron and scrap in oxygen-blown processes. The electric furnace is used to make steel, stainless steels, ferroalloys, and special alloys,

pdf characterization of fluxed iron ore pellets as

A new fluxed pellet for use in iron-making is obtained by mixing and indurating about 1 to about 20%, by weight of the pellet, of ground melt shop slag fines with similarly ground iron ore concentrate, so as to achieve particular ranges of silica content, CaO/SiO 2 ratio, and MgO content. The melt shop slag fines have been considered a waste material, but contain significant slag and metal values. A flux pellet will have higher melting properties in the blast furnace which means it converts from a solid-state to a liquid state at a faster rate. This improved melting performance has a positive impact on iron production and helps reduce the high energy costs of operating a blast furnace. Calculations show that coke use decreases by ...

Dec 21, 2016 In general terms, flux pellets are superior to non-flux pellets because they carry the slag together with the iron ore into the blast furnace, instead of furnace operators needing to load slag in separately. In a blast furnace, you basically load three things iron ore, through a pellet, or through sinter, coking coal, and flux (or slag). What are fluxed iron ore pellets used for Products.

Jun 01, 2017 Indian iron ore fines with high alumina content (2.5% Al 2 O 3 ) resulted in poor quality pellets and a study was under taken to establish suitable pellet chemistry through proper fluxing agents. Limestone fluxed pellets were prepared at varying basicity (0 to 0.8) and pyroxenite fluxed pellets at varying MgO contents (0 to 3%) to study their effect on the metallurgical properties. Total iron ore pellet production and sales by the Swedish company were 24.6 and 22.9 million tons, respectively, in 2017. This compares with 2016 production and sales of 24.0 and 22.7 million tons, respectively. The Kiruna operation delivered 14.4 million tons and the Malmberget/Svapavaara plants accounted for 8.4 million tons of 2017 sales.
