The electric arc furnaces used for steel recycling are hot enough and can be powered with renewable energy.

用于回收钢铁电弧炉温度可以熔水泥，电弧炉身可以靠可再生能源供电。

" That's the first sample of low carbon Portland cement produced in an electric arc furnace, ever, ever. "

我手中拿是低碳波特兰水泥第一，在电弧炉生产出来。

Investigators concluded, the disaster was caused by the ignition of combustible gas by electric arcs, sparks, or an open flame.

调查人员得出结论，这场灾难是由于电弧点燃可燃气体而引起， 火花或明火。

It was exhilarating, it was fascinating and listening to an electric arc furnace go off melting scrap metal, Erika, sounds like a hundred thunderstorms crackling at one time.

这是令人兴奋，令人着迷，听着电弧炉熔化废金属声音，埃里卡，听起来就像一百场雷暴同时噼啪作响。

During this process, an electric current passes through the gas, creating an electric arc, which moves in the direction of the gas stream while the arc length lengthens.

在此过程中，电流通过气体，产生电弧，电弧在气流方向上移动，同时电弧长度也随之变长。

Instead of those massive plants, it was mini and at the center, instead of the big, open-hearth furnace, it was powered by a smaller, more efficient, electric arc furnace.

它不是那些大型工厂，而是小型工厂，在中心，它不是大型平炉，而是由更小、更高效电弧炉提供动力。
