iron ore sintering for blast furnace
SINTERING AND PELLETISATION OF INDIAN IRON ORESSinter making is a method of fusing iron ore fines into larger particles suitable for charging into the blast furnace. Predominant source of iron in many blast furnace processes. This technology was developed for the treatment of the waste fines inof coke breeze sintering iron oreIron ore sintering is a very important process which produces sinter as a major burden for blast furnace ironmaking. In this process, iron ore and auxiliary materials, e.g., fluxes, unqualified sinter (called return fine), and coke breeze, are mixedof coke breezeSintering iron ore - Каталог продукции МеталлоинвестA lumped iron ore product that is used as a raw material for sintering. Due to its higher iron content than in blast furnace iron ore, sintering iron ore is perfect for sintering prior to being used in blast furnace production. Sintering iron ore is dried for ease of ...Ironworks - tec-science21/6/2018· The actual melting down and removal of the iron from the ores takes place in blast furnaces, which project about 30 m in height and have a diameter of about 10 m. Some blast furnaces even reach heights of over 70 m and diameters of 15 m. The temperatures of up to 2000 °C in the blast furnace require an extremely heat-resistant lining.

The mixture of iron ore and flux is called charge, which is fed into the blast furnace in layers together with coke (called charging)! Even if the iron content in the ores could be greatly increased by the processing, undesirable substances will still be present. For this ...Blast Furnace Anatomy #1 – To the Heart of Steelworks .31/7/2019· Before the iron ores enter a blast furnace, it undergoes 'sintering' which turns the pristine iron ore into more compact and appropriate sizes. The sintered iron ores become 'sinter.' The iron ores that come in just the perfect size .Recent advances in iron ore sintering: Mineral .Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use.

Optimal Sintering Conditions for Blast Furnace .
The sintering process is utilised to convert weakly-bonded iron ore granules into a partially fused porous sinter cake using coke breeze as fuel, and then into final product – iron ore sinter with specific properties. In a typical sinter strand, air is drawn down and a flame front is allowed to propagate at 1200~1400℃ through the granule bed.Sintering Plant For Blast FurnacePig iron making blast furnace: . ferromanganese smelting blast furnace of 20~ 550m³, auxiliary sintering machine, .
