Apr 02 2020 Primarily the goals of iron ore sintering are to produce consistent chemical composition to increase the strength of iron particles and to create a uniform particle size As such how iron ore is sintered depends on the intended purpose of the finished product
The iron blast furnace is the most widely used and efficient producer of liquid iron however emissions from sintering and coking cause environmental pressure for the integrated steel works The combustion of coke fines breeze during sintering contributes to greenhouse gases eg carbon dioxide and is a source of SO x and NO x emissions
ore fines and their potential impacts on the iron ore sintering process and sinter quality are required In this paper the sintering process and sinter structure have been analysed and the key factors affecting the sintering performance of iron ore fines including productivity and quality identified Under fixed sintering
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines recycled ironmaking products fluxes slagforming 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
