鋼のアーク加熱装置。 A method for producing molten steel comprising a container containing molten steel, a heating electrode and an immersion electrode extending in the vertical direction, the lower end of the immersion electrode being immersed in the molten steel, and the molten steel being heated by an arc generated between the heating electrode and the molten steel. In the arc heating device, the heating electrode and the immersed electrode are held by separate lifting and lowering drive devices, and the immersed electrode is provided with a hole penetrating in the longitudinal direction, and the upper part of the immersed electrode is provided with a hole that passes through the immersed electrode. An arc photodetector is disposed so that the arc light enters through the hole, and while the arc light is generated in response to an output signal of the arc photodetector,
An apparatus for arc heating molten steel, characterized in that the immersion electrode is equipped with an elevation control device for issuing a descending command signal to the elevation drive device for the immersed electrode.
