天铁3号高炉(600m~3)第三代炉役于1997年5月投产。1998年10月～1999年9月,连续12个月高炉利用系数超过2.1,平均利用系数达2.3,煤比达135kg/t,入炉焦比下降到438kg/t,吨铁成本864元/t,多项指标创天铁历史最好水平。在创高产、增效益的同时,生铁质量、安全生产及高炉顺行指标亦有了显著的提高。生铁合格率100％,一级品率达75％,各类生产事故为零,悬料次数
Tiantie No. 3 blast furnace (600m ~ 3) the third generation of furnace service put into operation in May 1997. From October 1998 to September 1999, the blast furnace utilization coefficient exceeded 2.1 for 12 consecutive months with an average utilization factor of 2.3, a coal ratio of 135kg / t, a reduction of coke ratio of 438kg / t, a cost of iron of 864 yuan / t , A number of indicators of a record high level of history in the sky. In a record high yield, increase efficiency at the same time, pig iron quality, safety in production and blast furnace along the line has also been significantly improved indicators. Pig iron pass rate of 100%, a product rate of 75%, all types of production accidents is zero, suspension times
