摘要： Sensors measure magnetic field components, and the measured fields are used to calculate and estimated transverse position of a longitudinal electric current flowing as an electric discharge across a discharge gap. Based on the estimated position, and according to a selected transverse trajectory or distribution of the estimated discharge position, magnetic fields are applied transversely across the discharge gap so as to control or alter the estimated discharge position. Inventive apparatus and methods can be employed, inter alia, during operation of a vacuum arc furnace.

摘要： A graphite lined crucible includes an upper horizontally extending flange having a seal ring around its periphery. The crucible may be raised by a hydraulic cylinder so as to bring the seal ring into engagement with the inside of a refractory lined roof. Electrodes supported by the roof extend downwardly into the crucible for melting the flux within the crucible. The roof and the crucible are air-tight thereby preventing air from entering the crucible. An exhaust port located in the upper portion of the roof is connected to a vacuum device for exhausting fumes from the crucible and for controlling the atmosphere within the crucible.
