武钢炼铁原料中含有较高的碱金属,给高炉生产带未危害。本文以热力学分析和高炉解剖资料为依据,提出在武铜原料条件下,用含碱金属低的原生精矿生产高碱度烧结矿,用含碱金属高的氧化精矿生产酸性烧结矿,有可能抑制碱金属在高炉内的循环富集,减轻碱金属对高炉生产的危害。 WISCO contains a high amount of alkali metal in its raw materials, which gives the blast furnace production zone unharmed. Based on the thermodynamic analysis and the blast furnace anatomical data, this paper proposes that the high-basicity sinter should be produced from primary concentrates containing low alkali metals and the acidic agglomerates should be produced from high-concentration alkali concentrates containing alkali metals, May inhibit the cycle of enrichment of alkali metals in the blast furnace to reduce the hazards of alkali metal blast furnace production.
