高炉喷吹物料及其演变趋势

介绍了几种高炉喷吹物料的作用及现状，指出凡是可以块状形式从炉顶加入的物料，均可以粉末形式从风口败炉内，作为高炉冶炼达到优质、高产、低耗、长寿的必要调剂手段；高炉喷吹应向以喷吹煤粉为主的复合喷吹方向发展，并与环境保护及二次资源利用结合起来。建议进一步开展对复合喷吹的研究开发工作，以及开展对高炉喷吹废弃可燃物的有关研究开发工作

MATERIAL INJECTION INTO BLAST FURNACE AND EVOLUTIONAL TREND

Present state and action of several BF material injection processes are introduced.It is indicated that every material,which may be fed into BF through the furnace roof in the form of lump,can be injected into BF at tuyere as powder,which is taken for an adjustable means required to achieve high quality,high yield, low consumption and long life. Combined injection method mainly based on pulverized coal injection should be taken as the developing trend of BF injection in consideration of the environmental protection and the secondary resource utilization. It is suggested that the combined injection and combustible waste material injection into BF, such as waste plastics and tyre, should be researched further.
