DC Electric Arc Furnace
DC Electric Arc Furnace
Providing the necessary direct electric power for heating electric arc furnaces (EAFs), especially in applications requiring more precise control and higher melting efficiency. The rectifier creates a more stable and controllable arc in the furnace, leading to better temperature control and optimized energy consumption. DC electric arc furnaces also offer higher energy density, resulting in shorter melting times and higher production rates. In the design and manufacture of Khazartransformer's electric arc furnace rectifiers, special precautions are taken for load fluctuations between short circuit and open circuit.
