我国当前钢铁企业无论从品种、质最、数量上均还不能满足国家建设的需要,每年都要花大量的外汇进口钢材,以1985年为例就进口了近2000万吨钢材,花费五、六十亿美元外汇。“七、五”规化要求生产5500万吨,力争6000万吨钢。因此,五年内要增加1300万吨生铁,增产的方针主要是立足于现有企业挖潜、改造配套、扩建。采取的措施:一是在现有重点企业及地方骨干企业增建9座1200m~3～4063m~3高炉,二是在现有企业中实行分层晋级、分档达标,向先进学习,挖潜增产。但如果不在大修时推进技术进步、采用国内外行之有效的新技术以改变
At present, China’s current iron and steel enterprises are still unable to meet the needs of national construction in terms of variety, quality and quantity. They have to spend a large amount of foreign exchange to import steel every year. In 1985, for example, they imported nearly 20 million tons of steel and spent five or six Billions of dollars in foreign exchange. “Seven, Five” regulatory requirements of 55 million tons of production, and strive to 60 million tons of steel. Therefore, to increase 13 million tons of pig iron within five years, the principle of increasing production should be based on tapping the potentials of existing enterprises, transforming supporting facilities and expanding them. Measures to be taken: First, to build nine 1200m ~ 3 ~ 4063m ~ 3 blast furnaces for existing key enterprises and local key enterprises; second, to implement advanced promotion in existing enterprises, achieve sub-standard compliance, and learn from advanced technologies so as to tap potential growth potential . However, if technological progress is not promoted during the overhaul, effective new technologies at home and abroad are used to change
