一、单电极直流电弧炉ASEA工业系统公司经过十年努力,已经制造了一种单根石墨电极直流电弧炉。这种炉子设计用来冶炼废钢料及预还原铁矿石粉料。它的优点为:能使电弧炉的电极消耗降低50％以上。试验是在一座30吨炉子上进行,结果表明,每熔化一吨钢石墨电极的消 First, the single-electrode DC EAF ASEA industrial systems company after ten years of hard work, has created a single graphite electrode DC electric arc furnace. This stove is designed to smelt scrap materials and pre-reduced iron ore powder. Its advantages are: can reduce the electrode arc electrode consumption of more than 50%. The test was carried out on a 30 tonne furnace and the results showed that for each ton of steel electrode melted
