据美国动力钢公司总经理Keith Busse称,该公司正在寻找废钢的替代品,同时寻找高炉的替代工艺。该工艺称RedSmelt铁矿还原工艺。目前正在建设的一套系统将向电炉提供铁水,其流程是先将铁矿石装入环形炉内,用煤基固态还原法进行还原,然后还原铁在热态被装至潜弧电炉中。电炉连续装料、分批出铁。环形炉采用电阻加热熔化铁并进行进一步的还原,脱除脉石、硫及灰分。液态铁水可铸造成铁锭,但大部分将直接装入电弧炉中。动力钢公司的子公司动力铁公司目前正在建几套新的生产设备,建成后将满负荷生产。该公司年产能为50～60万t,预计今年9月投产。
According to Keith Busse, general manager of American Power Steel, the company is looking for alternatives to scrap while looking for an alternative blast furnace process. The process is called RedSmelt iron ore reduction process. A system that is currently under construction will provide hot metal to the electric furnace by charging the iron ore into a toroidal furnace and reducing it with a coal-based solid state reduction process. The reduced iron is then hot-submerged into a submerged arc furnace. Electric furnace continuous loading, batch iron. The ring furnace uses resistance heating to melt the iron and perform further reduction to remove gangue, sulfur and ash. Liquid hot metal can be cast into iron ingots, but most will be loaded directly into the electric arc furnace. Power Iron Company's subsidiary, Power Iron, is currently building several new production facilities, which will be built at full capacity. The company's annual production capacity of 50 to 600,000 t, is expected to put into operation in September this year.
