摘　　要：针对"经济料"的大量使用和频繁变料对烧结矿低温还原粉化指标的影响,安钢从烧结原料结构、燃料配加量、烧结矿SiO2控制范围以及烧结矿R范围等方面分析影响烧结矿低温还原粉化强度的因素,从而改善烧结矿低温还原粉化指标,确保高炉块状带的透气性,实现经济、稳定、顺行。In view of the influence of large amount use of the＂economic raw material＂and frequent material changes on the low temperature reduction of sinter,factors affecting the low temperature reduction of sinter are analyzed through raw material structure,the amount of fuel,control range of Si O2 and R range of sinter,thus the low temperature reduction index of the sinter is promoted. That ensures the permeability of the lumpy zone in blast furnace and realizes the economic,stable and smooth operation.
