为了寻求节能和使用廉价原料和燃料以取代高炉的炼铁新工艺,世界各国正在进行多方面的研究和探索。最近,瑞典STORA和ASEA两公司联合研制成功的电还原炼铁新工艺,是生产铁水的另一条途径。该工艺分两步进行,首先将铁精矿在流化床中进行预还原,然后在直流电弧炉中进 In order to seek new energy-saving and new technology of using low-cost raw materials and fuel instead of blast furnace, many countries are conducting various research and exploration. Recently, Sweden STORA and ASEA two companies jointly developed a successful new electric ironmaking process, is another way to produce molten iron. The process is carried out in two steps, firstly the iron concentrate is pre-reduced in a fluidized bed and then in a DC electric arc furnace
