摘　　要："加钙品位"是作者提出的一个新概念,其定义为:铁矿石补加氧化钙达到高炉炉渣碱度要求时铁元素的质量百分含量,表达式为:TFe+CaO=Fe 100+SiO2×Rs-CaO×100。分别对铁矿石、铁精粉、烧结矿、球团矿等做了加钙品位、扣钙品位计算,并进行了比较和分析。结果表明:加钙品位能更客观、更合理地反映铁矿石的冶炼价值,而基础品位(通常说的品位)和扣钙品位则不能很好地反映铁矿石的冶炼价值。A new concept——Plussing Calcium Oxide Grade was put forward,which is the very mass percentage of iron element when Calcium Oxide addition fulfills the need of the basicity of the blast furnace slag,and the expression is TFe＋CaO=Fe 100＋SiO2×Rs-CaO×100.The Plussing Calcium Oxide Grade and Reduction Calcium Oxide Grade of iron ore,iron concentrate,sinter and pellet was calculated,analyzed and also compared.The results showed that： the Plussing Calcium Oxide Grade can reflect the smelting value more objectively and reasonably,while the basic grade and Reduction Calcium Oxide Grade can not.
