作者提出重视磁镜式双放弧电极直流钢包炉在我国应用的问题。
It is supposed to pay great attention to the application of the direct current ladle furnace with magnetic mirror bi-arc electrodes at home.
试验表明，三电极直流钢包炉技术可解决底电极式直流钢包炉存在的不足，使炉子加热速度快和不发生偏弧现象。
The results show that threeelectrode DC ladle furnace, increasing heating speed and without arc bias, can overcome the shortcomings of bottom-electrode DC ladle furnace.
