球扁钢用于建造万吨级出口船舶及国内各种远洋、沿海、内河船舶的船体结构。在船体结构上起脊椎骨和主要筋骨作用,是制造万吨级船舶必不可少的关键钢材。全国同行业中只有鞍钢和武钢生产球扁钢。武钢大型厂生产20号和22号两种规格的球扁钢。鞍钢大型厂和中型厂生产27号～20号、18～10号等九种规格的球扁钢,采用的钢号有2C、3C 及军用钢种。鞍钢生产球扁钢已有近三十年的历史,随着工艺技术的不断改进,产量、质量都得
Ball flat steel used in the construction of 10,000-ton export ships and various domestic ocean, coastal, river vessels hull structure. The vertebrae and the main bones in the structure of the hull are the essential steel for the manufacture of 10,000-ton ships. In the same industry, only Anshan Iron and Steel Company and Wuhan Iron and Steel Company production of flat steel. Wuhan Iron and Steel Company large-scale production of 20 and 22 specifications of the two-ball flat steel. Large-scale factory and medium-sized Anshan Iron and Steel Plant production No. 27 to 20, 18 to 10 and other specifications of the nine-ball flat steel, the steel used in 2C, 3C and military steel. Angang Steel flat steel production has nearly three decades of history, with the continuous improvement of technology, production, quality have to
