摘　　要：文章从蒙古粉矿化学成分、粒度组成、烧结基础特性以及生产应用后工艺参数调整等方面开展研究。研究结果表明,使用7%蒙古粉矿同比例替代麦克粉矿,烧结料层透气性变差,利用系数降低0.001 t/(m^(2)·h),固体燃耗升高0.83 kg/t,转鼓强度降低0.63个百分点,平均粒径降低0.05 mm,成品烧结矿中5~10 mm粒级占比减少0.12个百分点,直接材料成本降低8.15元/t。通过提高混合料水分0.1个百分点,提高燃料配比0.2个百分点,可保持烧结过程处于稳定状态。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/(m^(2)·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.
