Study On The Rational Various Mineral Ore Matching For Sintering Of Tiangang Iron And Steel Corp.

The performance of every iron ore fine agglomeration, rational scheme and technicalparameters of ore matching for sintering were studied in this paper. OM, SEM and EDSwere used to test the sample got from a series of experiments.Following were the main substances of this research: Rules of import-iron oresagglomeration, import-iron ores include Brazil CVRD iron ore,Indias high qualitymine,Brazil iron fine powder,Irani iron fine powder and Mauritania fine powder.Rules of rich iron ores of Tiangang agglomeration, it includes Laiyuan iron ore andQian'an iron ore. On the base of above studies, the rational ore matching for sintering wasstudied, and rational sintering scheme and technical parameters are educed. By studying,we found that intensity, finished product percent, reductive degree, low temperaturereduction degradation rate and distributing of mineral phase in sinters are improved byadding rational Brazil CVRD iron ore and Indias high mine in sintering process. On thebase of above studies, the best ratio of Brazil CVRD and Indias high quality mine, rationalmatching ore for sintering and technical parameters are received by planning scheme ofsinter and analyzing experiments. The results of this research enriched the theories of ironore agglomeration and may play an import role in production operation, process controland scientific research.
