在首届全国工业企业技术进步成就展览会的钢铁工业馆内,一件件展品、一串串比较数字、一张张图表都联系着一项项革新和发明创造。这些科研成果和高新技术装备,为钢铁工业的发展插上了腾飞的翅膀。 1949年全国钢产量只有15.8万吨,品种规格也少得可怜。1990年钢产量达到6604万吨,相当于建国初期年产量的413倍。特别是改革开放十多年来,钢铁工业蓬勃发展。1978年到1990年的12年间,铁产量翻了一番,净增3400多万吨,增长量超过改革前的29年。品种质量也有很大发展。50年代初,我国只能冶炼
In the steel industry hall of the First National Industrial Technology Progress Achievements Exhibition, a piece of exhibits, a string of comparative figures, and a series of charts all linked to a project of innovation and invention. These scientific achievements and high-tech equipment, for the development of the steel industry plugged off the wings. In 1949, the national steel output was only 158,000 tons, and the specifications of the products were pitifully small. In 1990, the steel output reached 66.04 million tons, equivalent to 413 times the annual output of the early years of the founding of New China. In particular, since the reform and opening up for more than a decade, the steel industry has boomed. In the 12 years from 1978 to 1990, the output of iron has doubled, a net increase of more than 34 million tons, an increase over the 29 years before the reform. Variety quality also has great development. In the early 1950s, our country only smelted
