高强度低冷裂缝敏感性的CF钢是七十年代日本钢结构朝着大型化、高参数化迅速发展的产物,为了满足国内高参数球罐用钢的急需,1980年机械部通用机械研究所与冶金部门鉴定了CF-62钢研制协议,武钢公司于1984年生产出了2炉50吨转炉(扩装72吨钢水) 模铸及1炉连铸工业试生产钢板。目前,对该钢号的基础试验研究工作已初告段落。武汉钢铁公司、通用机械研究所、钢铁研究总院等单位已分别完成了钢板的力学性能、抗H_2S应力腐蚀
High-intensity and low-temperature crack-sensitive CF steel is the product of rapid development of large-scale and high-parameter steel structure in Japan in the seventies. In order to meet the urgent need of domestic high-parameter spherical tank steel, the 1980 General Machinery Research Institute And the metallurgical sector identified CF-62 steel research and development agreement, Wuhan Iron and Steel Company in 1984 produced a 2 furnace 50 tons converter (expansion of 72 tons of molten steel) and 1 furnace continuous casting industrial trial production of steel. At present, the basic experimental study of the steel has been the beginning of the paragraph. Wuhan Iron and Steel Company, General Machinery Research Institute, Steel Research Institute and other units have completed the mechanical properties of steel, anti-H_2S stress corrosion
