Outline
In this paper, the research is carried out from such aspects as chemical composition, size composition, basic sintering characteristics and process parameters adjustment after production applications of Mongolian powder ore. The research results showed that the air permeability of sinter bed became worse, utilization coefficient was decreased by 0.001 t/ (m2·h), solid fuel consumption was increased by 0.83 kg/t, drum strength was decreased by 0.63 percentage point, average particle size was decreased by 0.05 mm, proportion of particle size of 5~10 mm in finished sinter was decreased by 0.12 percentage point and direct material cost was decreased by CNY 8.15 Yuan/ t when 7% Mongolian powder ore was used to replace the same proportion of Mac powder ore. The sintering process could maintain stable state by increasing moisture of mixture by 0.1 percentage point and fuel proportion by 0.2 percentage point.
