鞍钢中型轧钢厂是一九三四年建成投产的老厂。解放前,在日伪统治下的十年间,最高年产量还不到十万吨,一九四六年起国民党反动派搞了二年,只生产四千吨。解放后,在毛主席革命路线指引下,经过恢复生产和第一、第二两个五年计划期间,进行了大量的技术改造,生产有迅速发展。特別是无产阶级文化大革命之后,中型厂发生了深刻的变化,八年来,年年超额完成国家计划。实现了三百七十四项技术革新,自己制造各种专机四十八台。一九七○年年产突破了修正主义“五定五保”给中型厂限制的四十万吨的旧框子,一九七三年年产量猛增到相当于一九六五年的一点六倍,是日伪时期十年产量的总合。日伪时期只能生产六个品种和二十四种规 Anshan Iron and Steel rolling mill is built in 1934 the old factory. Before the liberation, the highest annual output during the ten years under the rule of Japan and the Puppet was less than 100,000 tons. Since 1946 the Kuomintang reactionaries engaged for two years and produced only 4,000 tons. After the liberation, under the guidance of Chairman Mao’s revolutionary line and through the resumption of production and the first and second five-year plans, a great deal of technological transformation took place and the rapid development of production was carried out. After the great proletarian cultural revolution in particular, the mid-sized factory has undergone profound changes. Over the past eight years, the state plan has been surpassed. Three hundred and seventy-four technological innovations were realized, and forty-eight special planes of all kinds were manufactured. Its annual output in 1970 broke through the old frame of 400,000 tons bound by the “Five Guarantees and Five Guarantees” of the revisionists to the medium-sized factories. In 1973, the annual output soared to 1.6 times that of 1965 , Is the total output of ten years during the Japanese-puppet period.
