WebApr 1, 2024 · There are three main physicochemical transformations in the rotary kiln furnace. The first one is the evaporation of free moisture. Then the thermal dissociation and removal of the chemically-bound water, also known as calcination. Third, partial removal of oxygen from iron and nickel oxides via reduction reactions with CO [1]. WebHowever in the coal/oil-based DR process, the reducing gas is generated from hydrocarbons (primarily coal, but sometimes oil and natural gas) in the reduction zone of the furnace, …

WebOct 2, 2024 · Iron ore concentrate is an output product from processed iron ores that have been milled (crush, grind, magnetic separation, flotation) to separate deleterious elements and produce a high-quality product. Sintering and pelletizing are economic and widely used agglomeration processes to prepare iron ore fines/iron concentrate for ironmaking use. WebIn a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based. WebBinderless cold bonded super fluxed pellet In order to produce the low melting oxidizing flux, the waste oxides of steel plant and iron ore fines have been agglomer- ated in presence of high percentage of burnt or hydrated lime. Pelletizing route has been followed. gosftp.ibsplc.com
