摘　　要：安钢实施"低成本运行"战略以来,安钢铁前系统紧紧围绕公司生产要求,不断优化烧结配料结构,炼铁不断优化高炉炉料结构,提高烧结矿和进口块矿比例,减少价格昂贵的进口球团的入炉比例,同时抓好高炉精料其他方面的工作,配合炉料结构的变化,采取了一系列技术措施,保持了高炉的长期稳定顺行,实现了炼铁的低成本运行。After Ansteel implemented the strategy of low cost to run,the system of ironmaking improved the structure of sinter blending,optimized the burden structure of blast furnace,increased sinter and lump ore's ratio imported,and reduced the proportion of expensive pellets imported.At the same time,a good job was did in other areas of concentrate material.With changes of the burden structure,a series of technical measures were taken to maintain a long-term stability of the blast furnace,and achieved low-cost ironmaking operation.

关 键 词：高炉 炼铁 炉料结构 低成本
