摘　　要：依据鞍钢炼铁工艺参数,利用铁矿石综合品位法和模拟单烧计算法对鞍钢自产精矿和常用外购铁矿粉进行经济性评价;利用修正后的冶金价值评价法对鞍钢常用块矿进行经济性评价,对铁矿石综合品位和模拟单烧计算品位的关系进行拟合。以模拟单烧计算品位为依据,分别对自产精矿和外购粉矿综合品位计算公式进行修正,修正后的评价方法能够指导企业铁矿石采购和降低炼铁成本。The economic evaluation for the concentrates prepared by Ansteel and frequently- used iron ore powders purchased was carried out by the Comprehensive assessment method for the grade of iron ore and simulation calculation method for sintering the one single iron ore according to the ironmaking process parameters used by Ansteel. The economic evaluation for frequently- used lump ore used in Ansteel was also done by the revised metallurgical value evaluation method and then the relationship between the comprehensive iron ore grade and the calculation grade of sintering the single iron ore by the simulation method matched. Based on the calculation grade of sintering the single iron ore by the simulation method, the formulas for respectively calculating the comprehensive grades of the iron ore concentrate and the powder ore purchased are revised. So the revised calculation method can be helpful to the enterprises in purchasing the iron ore and reducing the cost of ironmaking.
