直流电弧炉的历史可以追溯到本世纪的初期,由于当时的整流技术和设备条件的限制、这一技术并未引起人们的重视。到六～七十年代,随着大功率可控硅元件和整流技术的发展,直流电弧炉技术又重新提到议事日程,1982年西惠SMS SchLoemann公司在西德政府的资助下,在SMS铸钢车间,建造了第一台公称容量为12吨的直流电弧炉。第二台直流电弧炉在瑞典的AVeSta钢厂投
The history of DC electric arc furnaces can be traced back to the beginning of this century. Due to the limitation of rectifier technology and equipment conditions at that time, this technology did not draw much attention. From the 1960s to the 1970s, with the development of high-power thyristor components and rectifier technology, DC arc furnace technology was again mentioned in the agenda. In 1982, West Schwiemann SMS Schloemann Corporation with the support of the West German government, Steel plant, built the first DC capacity of 12 tons of DC arc furnace. The second DC electric arc furnace was cast at AVeSta Steel in Sweden
