DC power supply for vacuum consumable arc furnace

     Vacuum consumable arc furnace is mainly used for melting active and refractory metals such as titanium, zirconium, molybdenum, etc., and is a mature industrial melting method. Its characteristics are fast melting speed and the ability to produce large ingots, which can basically meet the requirements of general industry. The melting process of a vacuum consumable arc furnace is carried out under the action of an arc with low DC voltage and high current.
