包钢高炉的矿石基地是白云鄂博矿,矿石中含有稀土、氟、钾、钠等多种元素,给高炉冶炼带来了一系列的特殊性。自1979年以来,我厂通过对碱金属的控制,有效地解决了白云矿冶炼特殊性的一个方面,使生产有了明显的进步。一、碱金属问题的提出和解决苏良赫研究员在五十年代末期和杨永宜教授在1974年曾先后指出过,白云矿含有碱金属可能是包钢高炉结瘤约重要原因。1975年,炼铁厂和钢研所根据炉瘤中有大量碱金属存在,提出了“钾钠在高炉中的循环积累
Baotou blast furnace ore base is Bayan Obo mine, containing rare earth ore, fluoride, potassium, sodium and other elements, to blast furnace smelting has brought a series of special. Since 1979, our factory has effectively solved one aspect of the particularity of smelting of dolomite by controlling the alkali metals, and has made obvious progress in production. I. The Proposition and Solution of Alkali Problem In the late 1950s and 2001, Professor Yang Yongyi pointed out that the inclusion of alkali metals in Baiyun Mine may be an important reason for the nodule formation in Baotou blast furnace. In 1975, the ironworks and Steel Research Institute, based on the presence of a large amount of alkali metals in the hearth, proposed "the cyclic accumulation of potassium and sodium in the blast furnace
