Low - carbon agglomeration process of iron ores for green ironmaking
Iron ore sintering process is a major supplier of the agglomerate burden to the blast furnace.The heat source of the process is mainly coke and therefore it emits a certain amount of C02.Because of a large mass of the sinter production,the ratio of C02 emission in an integrated steelworks is nearly 20% and it occupies about 3% of the total emissions in Japan.Biomass will be an alternative energy source of the process since it is recognized as a carbon neutral fuel.Another possibility is metallic iron and lower oxides of iron contained in mill scales.Problems when using such fuels and their possible solutions are discussed.Further,updated technologies for the reduction of C02 emissions in the sintering process are introduced.
