优化高炉结构的目的是使不断变化的炉料结构更加趋于合理化,是一项广泛应用在炼铁生产中重要的技术方法,具有稳定炉况、保质增产、降低成本等优点。唐钢炼铁南区3 200m3高炉于2010年在保证炉况稳定的前提下,通过调整入炉矿结构,采取合理的技术操作措施,不仅优化了入炉矿结构,同时还改善了入炉自产烧结矿的性能,在取得较好的技术经济指标的基础上,通过降低入炉矿的成本,为生铁成本的降低打下良好的基础。自从优化结构以来,入炉矿的价格逐月由861.51元/t降至846.82元/t。
The purpose of optimizing the blast furnace structure is to make the changing charge structure tend to be more rationalized. It is an important technical method widely used in ironmaking production. It has the advantages of stable furnace condition, higher yield and lower cost. Tangshan Iron and Steel Southern Iron 3 200m3 blast furnace in 2010 to ensure stable furnace conditions, by adjusting the furnace structure, to take reasonable technical measures to not only optimize the furnace structure into the furnace, but also improve the sintering into the furnace On the basis of obtaining better technical and economic indexes, the performance of the mine can lay a good foundation for reducing the cost of pig iron by reducing the cost of entering the ore. Since the optimization of the structure, the price of ore into the furnace dropped from 861.51 yuan / t to 846.82 yuan / t from month to month.
