君津３号高炉高煤粉喷吹率下的操作结果［日］ＨｉｒｏｍｉｔｓｕＵｅｎｏ１引言为降低炼铁成本和在不久的将来替代焦炉，开发了往炉内大量喷吹煤粉的技术。在欧洲的有些高炉上，早已用２００ｋｇ／ｔ生铁以上的煤粉喷吹率进行实际操作。就是在日本，煤粉喷吹率已接近２０...
Operation Results at High Pulverized Coal Injection Rate of Kimgu No.3 BF HiromitsuUeno1 Introduction In order to reduce the cost of ironmaking and replace coke ovens in the near future, technologies have been developed for pulverized coal injection into the furnace. Some blast furnaces in Europe have long been practiced with pulverized coal injection rates above 200 kg / t pig iron. It is in Japan, pulverized coal injection rate is close to 20 ...
