摘要
攀钢高炉喷煤始于80年代初,当时的煤比为30～60kg/t。近几年来,通过采取一系列措施,如新建喷煤车间、改进喷煤设备和工艺、提高煤粉质量、改善原料条件、提高风温、改进高炉操作等,煤比逐年提高,1998年5月全厂4座高炉的平均煤比达到76.25kg/t,其中3号高炉平均煤比突破80kg/t。
The PCI of BFs started from early 1980s at Panzhihua I & S Group Co. ,and the PCI rate was only 30 - 60 kg/tHM. In recent years, a series of measures, such as building new PCI works, reforming PCI equipments and process,improving the quality of pulverized coal and burden,enhancing blast temperature,improving BF operation,and so on,was taken. As results,the PCI rate of BFs was enhanced year by year,the average PCI rate of all 4 BFs reached 76.25 kg/tHM and that of No. 4 BF exceeded 80 kg/tHM in May of 1998.
