The ‘R&D and preparatory research work for the blast furnace based innovative ironmaking technologies’ has started in FY2006 for usage of low graded raw materials and CO2 mitigation in ironmaking process. The production processes and reaction mechanisms in a blast furnace were studied for two innovative composites with iron oxide, metallic iron and carbon to enhance the carbon and CO2 reactions during FY2006 and 2008. For further developments at a pilot plant scale, a new project, ‘Development of innovative ironmaking process using low cost iron ore and coal’ has been started by JFE Steel Corporation, Nippon Steel Corporation, Kobe Steel, Ltd. Sumitomo Metal Industries, Ltd. and major Japanese Universities. The project has been partly supported by the New Energy and Industrial Technology Development Organization, (NEDO) in FY2009 – 2010 and by the Ministry of Economy, Trade and Industry (METI) in FY 2011 – 2012. This paper describes key technologies, the production process of the ‘Ferro-coke’ at a 30t/d pilot plant and experimental evaluation and simulation model development for blast furnace charging. Construction of heating and briquetting facilities has completed and standard briquetting conditions such as binder addition ratio and briquetting pressure has been established by the continuous operation. The carbonization shaft furnace has completed its construction in September, 2011 and carbonization batch tests was successfully carried out in December. Successive operation of briquetting and carbonization will be carried in the end of FY2011 and Continuous production trials and charging tests to a blast furnace is planned in FY 2012 to find process feasibility of the production process and technical subjects of blast furnace charging.
