1978年,我厂广大工人、干部和工程技术人员,在实现四个现代化的目标指引下,以新的跃进速度,全面地超额完成了国家计划和增产计划,在高炉冶炼钒钛磁钛矿上有了新突破。全厂在一座高炉大修(占两个月时间)、一座高炉中修(占27天)的情况下,生铁产量比国家计划超产了9.94％,比增产计划超产2.08％,合格率达到99.14％。各项主要技术经济指标与77年相比:利用系数提高了0.324,焦比降低了66公斤/吨铁,生铁合格率提高了8.59％,休风率降低了1.22％。由于操作技术的提高,高炉煤气利用CO_2达到15.55％,比历史最高水平(13.14％)上升了2.41％。炼铁厂历年的主要技术经济指标列于表1。
In 1978, under the guidance of the four modernizations, the vast numbers of workers, cadres and engineers and technicians of our factory comprehensively surpassed the completion of the state plan and production increase plan under the new leap forward speed, Have a new breakthrough. In the case of a blast furnace overhaul (accounting for two months) and a blast furnace repair (27 days), the entire plant produced overproduction of 9.94% over the national plan and overproduction of 2.08% over the plan to increase production, with a passing rate of 99.14%. The main technical and economic indicators compared with 77 years: utilization factor increased 0.324, coke ratio decreased by 66 kg / ton of iron, pig iron qualified rate increased 8.59%, the wind fell 1.22%. Due to the improvement of operation technology, the utilization of blast furnace gas reached 15.55%, an increase of 2.41% over the highest level (13.14%). The main technical and economic indicators of the ironworks over the years are shown in Table 1.
