摘　　要：攀钢在80年代成功地在一座高炉进行了煤比为40 kg/t和60 kg/t的工业试验,并开发了氧煤混喷技术。在国家“八五”攻关试验中又成功地进行了90 kg/t的氧煤混喷试验。以后,攀钢新建了年喷煤量达32万t规模的喷煤系统。制粉系统建成投产后,解决了许多遗留的工艺和设备问题。1998年全厂高炉平均煤比达到75kg/t,1999年1月煤比超过了90 kg/t。The PCI industrial tests with coal rate of 40 kg/t and 60 kg/t were successfully carried out at No. 1 BF of Panzhihua Iron &. Steel Group Co. in 1980s.With oxy-coal lance, a coal ratio of 90 kg/t was reached.Based on these works, a new PCI workshop was built, which can produce 3.2×105 t pulverized coal annually. The averaged coal ratio of 75 kg/t was reached in 1998, and 90 kg/t in January, 1999.
