文中阐明Fe_2O_3—SiO_2—CaO系中CaO/Fe_2O_3与CaO/SiO_2(碱度)的关系;把该相图人为地分为四个不同碱度与CaO/Fe_2O_3的特性区,并论述了各区矿相结构特征。建议在生产中应组织低CaO/Fe_2O_3高碱度烧结料进行生产,控制烧结矿中全铁含量≥45.54%,SiO_2含量≤12.17%,CaO含量以CaO/Fe_2O_3≈0.35(或CaO/TFe≈0.5时),可作为较佳比例范围,控制CaO/Fe_2O_3(?)0.7时,可作为CaO的最大极限含量,这样可以获得高产优质低能耗的烧结矿。
In this paper, the relationship between CaO / Fe_2O_3 and CaO / SiO_2 (basicity) in Fe_2O_3-SiO_2-CaO system is illustrated. The phase diagram is artificially divided into four characteristic zones with different basicity and CaO / Fe_2O_3, Structure. It is suggested that low-CaO / Fe_2O_3 high basicity sintering materials should be organized for production to control the total iron content in the sinter to be ≥45.54%, the SiO_2 content to be less than 12.17% and the CaO content to CaO / Fe_2O_3≈0.35 (or CaO / TFe≈0.5 ), Which can be regarded as the better proportion range. When CaO / Fe_2O_3 (?) 0.7 is controlled, it can be regarded as the maximum limit content of CaO, so that sinter with high yield, high quality and low energy consumption can be obtained.
