烧结矿成分的稳定,是高炉实行精料方针的一个重要内容,而建立完善的原料中和混匀设施又是烧结矿成分稳定的基本保证。控制烧结原料成分波动,主要是指铁和二氧化硅的含量。日本早就规定烧结矿铁含量的波动范围小于±0.5％,二氧化硅波动小于0.10％。而我国有矿山基地的大型钢铁企业(如鞍钢、武钢、攀钢)对铁含量波动范围仅要
The stability of the sinter composition is an important content of the blast furnace to implement the principle of concentrate, and establish and improve the raw materials and mixing facilities is the stability of the basic guarantee sinter. Control of raw material composition fluctuations, mainly refers to the iron and silica content. Japan has long stipulated that the fluctuation range of iron content in sinter is less than ± 0.5% and the fluctuation of silicon dioxide is less than 0.10%. However, large-scale iron and steel enterprises (such as Anshan Iron and Steel Company, Wuhan Iron and Steel, Panzhihua Iron and Steel) mine base in our country on the iron content fluctuation range only
