Different aspects of technologies and equipment for secondary refining of liquid steel in the ladles with bath heating by DC arc and various disposal of electrodes are examined. The principal shemes and calculated characteristics of some projects of pilot aggregates ladle-furnace and vacuum arc degassing, designed by three institutes: VNIIMETMASH, TsNIICHERMET and VNIIETO are given. Technico-economic and ecological advantages of metal heating by DC or plasma arc and results of executed experiments give the foundation for continue of works in this direction.
