Abstract Abstract: on the basis of the analysis and research of the several ordinary imported ores ,the research of optimizing the ore proportioning which used the extra fine concentrate A of Taiyuan steel mill which size is 85 percent below 320 meshes and the several imported ores was studied,it is found out the reasonable ore proportioning technology which apply 38 to 45 percent of concentrate A and the ores from Australia and Brazil. In order to cope with the negative influence of financial crisis and make full use of owned-resource and cheap imported ores,the steel works enhance the proportion of concentrate A to 51 percent and add 9 percent of E ore from Australia instead of the expensive D ore from Brazil in the latter half of 2008. The technology adopted a series of effective measures which including optimizing the technologic parameter of mixture pelletizing,content of moisture,machine speed and the open degree of blower valve.The yield and quality of sinter ore completely satisfied the demand of large blast furnace furthermore it lay the foundation of adding up the proportion of iron,save coke ratio and optimize index of the 4350m3 blast furnace .The cost of sinter ore proportioning decrease about 86 million yuan per year arriving at great effect.
