“七五”期间,是我国钢铁工业蓬勃发展的五年,钢产量提前两年超额完成“七五”计划,1989年突破6000万吨,1990年产钢达6604万吨;钢铁产品品种结构大有改善,产品贸易稳步提高。与此同时,钢铁生产各项技术经济指标有了新的突破,节能降耗工作成绩显著。“七五”期间,通过开展系统节能,采用了各种节能新技术,使吨钢综合能耗由1985年的1.75吨标准煤下降到了1.62吨标准煤,其中重点钢铁企业的吨钢综合能耗已下降到1.2吨标准煤。五年间,冶金系统累计节约标准煤700万吨,取得了钢铁产量增长,能耗下降的好成绩。从节约金属的情况来看,“七五”期间成绩也是显著的,效益也是可观的。
During the “Seventh Five-Year Plan” period, China’s iron and steel industry boomed for five years. Its steel output surpassed the “Seventh Five-Year Plan” two years ahead of schedule, surpassing 60 million tons in 1989 and 66.04 million tons in 1990; There has been improvement, and trade in products has steadily risen. In the meantime, new breakthroughs have been made in various technical and economic indicators of steel production, and remarkable achievements have been made in energy saving and consumption reduction. During the “Seventh Five-Year Plan” period, a series of energy-saving new technologies were adopted to carry out systematic energy conservation so that the comprehensive energy consumption per ton of steel dropped from 1.75 tons of standard coal in 1985 to 1.62 tons of standard coal, of which the comprehensive energy consumption per tonne of key steel enterprises Has dropped to 1.2 tons of standard coal. In five years, the metallurgical system has saved a total of 7 million tons of standard coal and achieved good results in the growth of steel output and energy consumption. From the perspective of saving the metal, the achievements during the “Seventh Five-Year Plan” period are also remarkable, and the benefits are also considerable.
