阐述了氧化铁皮的形成原因及成分,介绍了氧化铁皮对烧结矿的理化性能、燃料消耗及产最的影响.氧化铁皮具有一定的去磷能力,可以显著加速初期渣的成渣过程,提高吹炼前期去磷等.生产实践证明,在相同成本条件下,氧化铁皮在炼钢厂使用比在烧结厂使用效益更为显著,为公司创造效益72 302元.同时炼钢一倒三命中率提高了11.8％,更有助于护炉工作的开展,冶炼周期缩短了0.2 min.实现了氧化铁皮的高效利用,有助于为公司创造效益.

The formation cause and composition of the iron oxide scale are reviewed.The effects of the iron oxide scale on the physical and chemical properties,the yield and the fuel consumption of sinter ore are introduced.The iron oxide scale has a certain ability of dephosphorization,which can significantly accelerate the slagging in the early process,and improve the dephosphorization ability in early stage of the blowing.The production practice shows that,the iron oxide scale used in steel mills can create benefits with 72 thousand and 302 yuan for the company,which is higher than that created by the iron oxide scale used in sintering with the same cost.At the same time,one to three hit rate is increased by 11.8％,which is more helpful to carry out the work of protecting furnace.The smelting period is shortened by 0.2 min,which can realize the efficient utilization of the iron oxide scale and create benefits for the company.
