本文全面地分析了高炉与非高炉炼铁工艺的技术特点,并对各种工艺的投资、成本等进行了全面比较。各种不同的炼铁工艺具有各自不同的冶炼特点和经济效果,因此应根据资源供应、地区条件、工厂规模、产品纲领等不同情况进行因地制宜地选择炼铁工艺流程,以达到技术上可行,经济上合理的目的。
This paper comprehensively analyzes the technical characteristics of blast furnace and non-blast furnace ironmaking process, and makes a comprehensive comparison of the investment, cost and other aspects of various processes. Different ironmaking processes have different smelting characteristics and economic effects. Therefore, the ironmaking process should be selected according to different conditions such as resource supply, regional conditions, factory scale and product program, so as to achieve technically feasible and economic On a reasonable purpose.
