ABSTRACT
Since the 1 950s，lots of C02 emissions caused by the industrial revolution had made extreme weather events and exacerbate water shortages in northem and drought in southern happen frequently．These environmental changes had serious effect on agiculture and industry．C02 emissions of steel industry in China occupies 1 5％of the national total emissions．The ironmaking in blast fumace accounts for about 70％of the total C02 emission in steel
indus仃y．Therefore，it is important to use less carbon in ironmaking for reducing C02 emissions of steel industry．Crude steel production increases rapidly in our country realizing the new industrialization process．It causes resources and energy crisis．Above of those leaded to the profit space reduce．So the development the technology of poor quality coal--low·-grade iron and

expanding the range of raw fuel used in blast furnace ironmaking are the key
to enhance steel enterprises competitiveness．
For this purpose，the study is based on the blast furnace metallurgical principles and the analysis dynamic cutting—edge research in domestic and foreign．The non—coking coal and iron ore are crushed and mixed，after they are thermoformed and coked，C—O-Fe contact distance become shorter and CIC gasification reaction is easer to occoure at low temperature．Fe catalyst and lower CIC gasification thermodynamics characteristics can reduce the top gas and lumpish tempera
