前言武钢是我国大型钢铁企业之一,自1958年1号高炉建设投产到1988年底止,总计生产生铁6320.06万吨,粗钢5383.17万吨,共创利税108亿元,为我国四化建设做出了重要贡献。三十年来,武钢的发展经历了艰难曲折的路程,炼铁、炼钢和轧钢三个主体生产系统的生产能力长期处于不平衡的状态,经济效益受到很大的影响。特别是1978~1979年一米七轧机系统三厂一车间相继建成投产后,轧钢系统已形成年产480~490万吨一次材的规模,每年需要560~570万吨粗钢,
Foreword Wuhan Iron and Steel is one of China’s large iron and steel enterprises, since the 1958 blast furnace construction and production to the end of 1988, a total of 6320600 tons of pig iron and crude steel 53831700 tons, a total of 10.8 billion yuan of profits and taxes, made for the four modernizations of our country The important contribution. Over the past 30 years, the development of WISCO has experienced a difficult and tortuous journey. The production capacity of the three main production systems of iron-making, steelmaking and rolling steel has been in an unbalanced state for a long time and the economic benefits have been greatly affected. Especially from 1978 to 1979, the first mill, the third mill and the first mill of 1978 Mill System was put into production one after another. The rolling system has formed a scale of 480 to 4.9 million tons of primary materials each year, requiring 560 to 5.7 million tons of crude steel annually,
