直流电弧炉(Direct current electric arc furnace has only one electrode mast arm and a single graphite electrode which acts as the cathode. 直流电弧炉只有一个电极横臂和一根作为阴极的石墨电极。)
电弧炉(① Much of the productivity gain achieved by the electric arc furnace over the past 10 ~ 15 years was related to oxygen use in it. 在过去 10 ~ 15 年中，电弧炉生产率的提高大多得益于炉内用氧。② The electric arc furnace productivity increased from 32 tonnes per hour to 85 tonnes per hour while power consumption decreased from 494 kWh/ tonne to 357 kWh/tonne. 该电弧炉生产率由 32t/h 提高到 85t/h, 而用电量由 494kW • h/t 下降到 357kW ・ h/t。)
电弧炉炉尘(Conway Steel has developed a technology to recover zinc and iron from electric arc furnace dust by a shaft furnace that is similar to the blast furnace operation. 康韦钢公司开发出一项利用竖炉从电弧炉炉尘中回收锌和铁的技术。该竖炉的操作与高炉操作相类似。)
电弧对炉墙的辐射(At the start of meltdown in electric arc furnace the radiation from the arc to the sidewalls is negligible because the electrodes are surrounded by the scrap. 电弧炉开始熔化时，电极被废钢包围，因而电弧对炉墙的辐射作用可以忽略不计。)
双炉壳直流电弧炉(The expansion program includes a new 150-tonne twin-shell dc electric arc furnace, ladle metallurgy furnace, single-strand continuous slab caster (slabs 5- in. thick, 35.4 to 102. 4-in wide) and walking beam continuous heating furnace. 该扩建规划包括新建一座150 t 双壳直流电弧炉，一座钢包冶金炉，一台单流板坯连铸机(板坯厚5 in, 宽35.4 - 102. 4in) 和一座步进梁式连续加热炉。)
