在磁铁矿精矿粉的烧结配料中加入硼－镁复合添加剂，可显著提高烧结生产效率及烧结矿的质量。经２４ｍ ２ 烧结机烧结及１８０ｍ ３ 高炉冶炼工业试验表明：采用复合添加剂技术及相应工艺后，烧结机利用系数由１．５６５ｔ／ｍ ２·ｈ提高到２．０９３ｔ／ｍ ２ ·ｈ；燃料消耗由９２．３５ｋｇ／ｔ降低到５４．０４ｋｇ／ｔ；高炉利用系数由２．３１５ｔ／ｍ ３·ｄ 提高到２．９５５ｔ／ｍ ３·ｄ；入炉焦比由６３０．４３ｋｇ／ｔ降低到５１９．６９ｋｇ／ｔ。
Adding the boron-magnesium composite additive to the sintering ingredients of the magnetite concentrate powder can obviously improve the sintering production efficiency and the quality of the sinter ore. After 24m 2 sinter sintering and 180m 3 blast furnace smelting industrial tests showed that: the use of composite additive technology and the corresponding process, sintering machine utilization factor increased from 1.565t / m 2 · h to 2.093t / m 2 · h; fuel consumption From 92.35kg / t to 54.04kg / t; the blast furnace utilization coefficient increased from 2.315t / m 3 · d to 2.955t / m 3 · d; the coke ratio decreased from 630.43kg / t to 519 .69kg / t.
