采用当代高新技术进行大修改造的首都钢铁公司二号高炉,自今年5月18日开炉点火以来,利用系数(即高炉-立方米有效容积一昼夜产铁吨数)连创世界新纪录。投产的第24天,利用系数就达到2.52,创造了开炉达产的世界纪录,以后又稳步提高到2.6和2.7以上,8月21日突破2.8,再创世界冶金史上的奇迹。 高炉利用系数是衡量高炉生产水平高低的最重要的指标,也是反映炼铁技术高低的重要标志。据有关资料,1990年我国十大钢铁企业高炉利用系数平均为
Utilizing modern high technology to make major overhaul, Capital Steel II No.2 blast furnace has set a new record in the world by utilizing the coefficient (blast furnace - effective cubic meter of cubic meters of iron and steel tonnage produced day and night) since the furnace started firing on May 18 this year. On the 24th day of operation, the utilization factor reached 2.52, creating a world record of open-hearted production and steadily increasing to 2.6 and 2.7 in the future. It exceeded 2.8 on August 21 to create a miracle in the history of metallurgy in the world. Blast utilization factor is a measure of the level of production of blast furnace the most important indicator, but also reflect the level of iron and steel technology is an important symbol. According to relevant information, in 1990 China’s top ten iron and steel enterprises blast furnace utilization coefficient averaged
