摘　　要：2000年,在实验室条件下对10种试验煤的理化性能进行了检测,通过煤种优化的相关计算得出单喷时喷吹B煤和混喷时喷吹B和A煤效益最佳的初步结论。2001—2003年,首钢高炉喷吹煤种优化的工业试验获得成功,实现了混煤喷吹及煤比提高,取得了较好的技术经济指标,并验证了实验室的研究结论。工业试验中提出了煤比提高过程中的冶炼规律及提高煤焦置换比的措施。In the lab condition,the physical and chemical performance of ten coals was inspected in 2000,the preliminary result had been educed by optimizing research of injection coal species. A coal is optimal when injecting alone coal and A-B mixed coal is optimal when injecting mixed coals.The Shougang successfully went along the industry experiment of the optimization of injection coal species in 2001-2003.It realized mixed coal injection in BF and higher coal rate ,resulting in good technical and economical index. The smelting rules during advancing the coal rate and the methods for advancing the coal-coke exchange ratio were summed.
