碱金属的循环富集是使高炉炉况恶化和导致结瘤的一个重要原因.矿石中大量氟的存在加剧了碱金属的危害.本文研究了生产高炉内碱金属的平衡及影响炉渣排碱的因素.总结了冶炼含碱金属炉料保证高炉顺行和防止结瘤的基本经验.
The cycle enrichment of alkali metals is one of the important reasons for the deterioration of blast furnace condition and the formation of nodules.The presence of a large amount of fluorine in the ore exacerbates the damage of alkali metals.This paper studies the balance of alkali metals in blast furnace and the influence of slag alkali Factors summarized the basic experience of smelting alkali-containing metal charge to ensure smooth blast furnace and prevent nodulation.
