摘要：
The electrical conditions of operation of ac and dc 0.5- to 25-t furnaces, namely, the installed, active and net powers, the maximum electric arc voltage, the electric arc operating current, and the electrical efficiency, are considered and compared. The parameters of a dc twin furnace, where one power supply is used for two furnaces and the periods of melting and finishing of a liquid metal in these furnaces are separated in time, are analyzed. © 2018, Pleiades Publishing, Ltd.
