计算了铜冷却壁相对于铸铁冷却壁的投资增加额。列出了高炉应用铜冷却壁后发生变化的相关成本因素。以 2 0 0 0m3 高炉为例计算了大高炉应用铜冷却壁的主要效益。分析了 30 0～ 6 0 0m3 小高炉使用铜冷却壁的经济可行性。得出的结论是 ,应用铜冷却壁不论对大高炉还是中小高炉都能产生良好的经济效益 The increase of investment in copper stave relative to cast iron stave was calculated. The cost factors associated with changes in the blast furnace after the application of copper staves are listed. Taking the 200m3 blast furnace as an example, the main benefit of using copper stave for large blast furnace is calculated. The economic feasibility of using copper stave in 30 0 ~ 600m3 blast furnace was analyzed. The conclusion is that the use of copper cooling stave can produce good economic benefits for both large and small blast furnaces
