针对中国当前炉料结构的合理性在高炉炼铁节能减排中的效果和地位,进行了系统的分析和论述。提出高炉炼铁“合理的炉料结构”这一理论概念和实践:高炉炼铁要实现精料;现代烧结是精料加工厂;不宜选用烧结工艺进行铁精矿造块;球团具有更优越的冶金性能;低品位含铁原料加工成预还原金属化炉料对高炉炼铁节能减排是有利的。
Aiming at the effect and status of the rationality of the current charge structure in blast furnace ironmaking in energy saving and emission reduction, a systematic analysis and discussion are given. Put forward the theory and practice of blast furnace ironmaking “reasonable charge structure ”: the blast furnace ironmaking should realize the fine material; the modern sintering is the fine material processing factory; Should not choose the sintering craft to carry on the iron concentrate manufacture; The pellet has more Superior metallurgical properties; processing of low-grade ferrous raw materials into prereduced metallurgical charge is beneficial to blast furnace iron making energy saving and emission reduction.
