资源的匮乏、环境的污染现状,迫切需要节能减排。我国现代化建设中,钢铁消耗量惊人。高炉炼铁是生产生铁的主要方法,但非高炉炼铁炼铁可减少排放球团、烧结等污染物,主焦煤利用较少。通过对行业的分析,以非高炉炼铁需要较高质量的原燃料,比如天然气,生产规模不大,难以有效普及开来。熔融还原比高炉炼铁的耗能量大已是不争的实时。 Lack of resources, the status of environmental pollution, the urgent need energy-saving emission reduction. In our modernization, the consumption of steel is staggering. Blast furnace ironmaking is the main method of producing pig iron, but non-blast furnace ironmaking can reduce emission of pellets, sintering and other pollutants, the main coking coal utilization less. Through the analysis of the industry, non-blast furnace ironmaking needs higher quality raw fuel, such as natural gas, which is not large-scale production and difficult to popularize effectively. Melting reduction blast furnace ironmaking energy consumption is an indisputable real-time.
