一、前言近年来高炉中碱金属的危害引起国内外炼铁工作者的广泛重视。目前武钢高炉碱负荷约7～9公斤/吨铁,已造成危害。本文着重论述武钢高炉碱金属的来源及其在高炉各部位残砖、渣皮及炉料中的富集分布状况,并通过热力学计算对武钢高炉内碱金属的行为进行探讨。二、武钢高炉碱金属的来源武钢高炉常用块矿主要是海南矿、澳矿、清路矿、综合矿等。人造富矿由武钢烧结厂一烧、三烧车间提供,高炉熟料约80％,常用原燃料的化学成分见表1。从表1可见,清路、广南等矿碱金属含量较高,但高炉碱金属的主要来源是烧结 I. Introduction In recent years, the hazards of alkali metal blast furnace caused widespread attention by iron and steel workers at home and abroad. At present, Wuhan Iron and Steel blast furnace alkali load of about 7 ~ 9 kg / ton of iron, has caused harm. This paper focuses on the sources of alkali metals in blast furnace of WISCO and their enrichment and distribution in residual bricks, skins and charge in various parts of blast furnace. The thermodynamics calculation is used to discuss the behavior of alkali metals in blast furnace of WISCO. Second, the source of WISCO blast furnace Alkali blast furnace commonly used lump ore is mainly Hainan mine, Australian mine, Qinghai mine, integrated mine and so on. Man-made rich ore from WISCO sintering plant a burn, three burn shop, about 80% of blast furnace clinker, the chemical composition of common fuels in Table 1. As can be seen from Table 1, the contents of alkali metals in Qingnian Road and Guangnan Mine are higher, but the main source of blast furnace alkali metal is sintering
